On Today’s Zero Limits Podcast I chat with Greg Lapin current Law Enforcement SWAT Operator and Lapin owns an exceptional jiu jitsu academy in Mandeville, Louisiana. Lapin spent eight years as a Louisiana Law Enforcement Officer with the majority of his time in Special Investigation and Narcotics units. He went on to work for Triple Canopy conducting high threat protection for the Department of State in conflict zones. Lapin was then recruited for a Department of Defense program in which he also worked in conflict zones while deployed. He has conducted various missions for both government and non-government clients around the globe. Lapin is currently a Sheriffs Deputy assigned to SWAT, an instructor for both firearms and Brazilian Jiu-jitsu, and is also an avid USPSA competitive shooter. Let’s GO!McQuilty developed resilience, a positive mindset, and fought back to be deployed again. He deployed to Afghanistan in 2011 with the 2nd Battalion, Royal Australian Regiment. On the 13 August 2011, McQuilty’s life changed again, forever. McQuilty was Wounded-in-Action by an improvised explosive device detonated under his vehicle. The vehicle was thrown ten metres from the blast site, McQuilty was ejected from the rear hatch and thrown thirty metres and landed on the side of the road headfirst. Let’s GO!

Today, he shares his story of the accident, his miraculous physical recovery, and the extreme hardships he faced following the incident. He explains how a traumatic brain injury led him to a psych word, on psychiatric medication – and how he started his journey to healing, and supporting others to do the same.
On today’s Zero Limits Podcast I chat with Chris May former Australian Army Armoured Corps crewman of the ASLAV and Bushmaster PMV. Chris joined the army at the age of 17 with his first posting was to Brisbane to C Squadron, 2nd 14th Light Horse Regiment ( Queensland Mounted Infantry). Chris’s brother Scott was already posted there as he had joined in mid ‘05. He then posted to B Squadron 3rd / 4th Cavalry Regiment in Townsville in 2009 and was immediately attached to Bravo Company on Mentoring and Reconstruction Task Force 2 (MRTF2) Afghanistan with 1 RAR Battle Group. He deployed again in 2011 whilst still at B 3/4, this time with the Mentoring Task Force 3 (MTF3) as part of the 2 RAR battle group Afghanistan. In September 23rd, 2011 the PMV Chris was commanding struck an IED which resulted in destroying the vehicle and both the driver and Chris were wounded in action with both escaping serious injury.

He would apply these lessons in East Timor in 2001 treating children and adults impacted by the conflict. All his training would not prepare him to see the horrors of war in Iraq in 2006 and his mind was injured. Upon returning home McQuilty delved into a nightmare ridden life, consuming alcohol to drown out the horrors of his time in Iraq. He was lucky to have his wife, who along with their two kids saved him from a perilous journey of minimal sleep, nightmares, flashbacks and suicidal thoughts.

Matt shares his own inspirational story about resilience and triumph over adversity. After 10 years as a front-line Police Officer with SA Police, witnessing constant human depravity and the failings of the system, Matt was diagnosed with severe Post Traumatic Stress and Depression. Matt almost lost his marriage and family and was battling suicidal thoughts when his deep depression and reckless behaviour led to his arrest whilst at work in 2015. Listen in for the whole story, let’s GO!
Field attended Macquarie University to receive training in early childhood education, and founded the Wiggles with fellow students Murray Cook, Greg Page and former bandmate Jeff Fatt in 1991. He worked as a preschool teacher for two years before the success of the Wiggles led him to focus on children’s music full-time. The Wiggles became one of the most successful and active groups in Australia. Field, who wears a blue shirt while performing with the Wiggles, was responsible for the production aspects of their stage and television shows, albums, and DVDs. His issues with chronic pain and depression, which almost forced him out of the group at the height of their success, are well-documented. After the departure of Cook, Fatt, and Page in 2012, he is the only remaining original Wiggle. Get ready for this one! Let’s GO!

Sentinel Foundation was founded with one goal in mind – to end underage children being exploited around the world. While this cause isn’t new, our method to achieve it is. We have the personnel, technology, the law enforcement support, and more importantly the perseverance to see it through. The Sentinel Foundation Operations team focuses on targeting elusive child traffickers that use highly skilled methods to find and exploit their victims. Children in underdeveloped and under resourced countries have virtually no defense against these networks.
Corporal Huggett was awarded the Medal for Gallantry and the citation says he displayed the highest standards of gallantry and personal courage on operations in Afghanistan in 2007. Let’s GO!On todays Zero Limits Podcast we speak to Jorge Kohn a former US Navy Sonar Technician / VBSS Sailor. Jorge’s first ship posting was to the USS Cole which was a target of a suicide attack. On October 12, 2000, suicide terrorists exploded a small boat alongside the USS Cole—a Navy Destroyer—as it was refueling in the Yemeni port of Aden. The blast ripped a 40-foot-wide hole near the waterline of the Cole, killing 17 American sailors and injuring many more. After spending 20 years of service in the US Navy Jorge discharged and now operates Makai Metal Works forging knives. Makai Metal Works recently forged knives made from steel from the World Trade Trade Centre for a veterans fund raising campaign. To find out more have a listen! Let’s Go!

The analysis of lake sedimentary records can be used to assess how strongly these recent changes have altered lake ecosystems. Sediments deposited during the last millennium from Lake Blokkvatnet, Prins Karls Forland, were analysed using a multiproxy approach, including stable isotope and X-ray fluorescence analysis. The results were interpreted as reflecting variability of (1) soil organic matter inwash, and potentially catchment and lake primary production, and (2) catchment weathering and erosion. Organic content began increasing after 1920 AD to the present, likely in response to warming. Earlier peaks of a similar magnitude occurred on three occasions since 1300 AD, with evidence indicating that these may have coincided with multidecadal-scale periods with higher temperatures, reduced sea ice and negative phases of the North Atlantic Oscillation. Catchment weathering and fluvial erosion began to increase around 1800 AD and peaked during the early twentieth century, potentially due to rising temperatures in autumn and winter causing increased liquid water availability. The records suggest that similar levels of erosion and weathering occurred between approximately 1300 and 1600 AD, spanning the transition from the Medieval Climate Anomaly to the Little Ice Age.

Arctic lakes are exposed to warming during increasingly longer ice-free periods and, if located in glaciated areas, to increased inflow of meltwater and sediments. However, direct monitoring of how such lakes respond to changing environmental conditions is challenging not only because of their remoteness but also because of the scarcity of present and previously observed lake states. At the glacier-proximal Lake Tarfala in the Kebnekaise Mountains, northern Sweden, temperatures throughout the water column at its deepest part (50 m) were acquired between 2016 and 2019. This three-year record shows that Lake Tarfala is dimictic and is overturning during spring and fall, respectively. Timing, duration, and intensity of mixing processes, as well as of summer and winter stratification, vary between years. Glacial meltwater may play an important role regarding not only mixing processes but also cooling of the lake. Attribution of external environmental factors to (changes in) lake mixing processes and thermal states remains challenging owing to for example, timing of ice-on and ice-off but also reflection and absorption of light, both known to play a decisive role for lake mixing processes, are not (yet) monitored in situ at Lake Tarfala.
Late Glacial and Holocene soils and sediments in southern Chile contain an important record of explosive volcanic activity since the end of the last glaciation, and have considerable potential for the development of a regional tephrostratigraphical framework. This paper reports the discovery of several new tephra deposits from the Hualaihue region (similar to 42 degrees S) of southern Chile. Eruption sizes, constrained from field observations, and ages, constrained by 25 new radiocarbon dates, show that the volcanoes of the Hualaihue peninsula have had relatively few explosive, tephra-generating eruptions during the Holocene. An eruption of Apagado deposited similar to 1 km(3) of bedded basaltic scoria at similar to 2.6 calibrated (cal) ka BP, and Hornopiren produced a similar, but volumetrically-smaller unit at similar to 5.7 cal ka BR Activity at Yate over the same time period has been predominantly characterised by lava production, although small explosive eruptions, the products of which span a range of compositions, have also occurred, including one at similar to 0.9 cal ka BR The northern part of the regional tephra sequence is dominated by andesitic pumice fall deposits derived from Calbuco volcano. These include deposits from several eruptions during a 3500-year-long period at the start of the Holocene, as well as two large explosive eruptions in the past 2000 years. A distinctive rhyolitic tephra layer that is interbedded with the locally derived tephra sequence is the Cha1 unit, from Chaiten volcano, 108 km south of Hornopiren. This rhyolitic pumice deposit, dated at similar to 9.75 cal ka BP, is the largest volumetrically of those described here, with a volume of 3.5 km(3). This new tephrostratigraphy covers a region whose volcanic history was previously very little known, and contributes to a regional record of large explosive eruptions that now spans a 500 km-long segment of the southern Andean arc, between Calbuco and Hudson volcanoes.

Environmental changes and their consequences on biodiversity are known to have far-reaching effects on the resilience of animal populations and associated livelihoods around the world. To counteract negative demographic and economic effects on pastoralism, knowledge about the historical and current status of the environment is essential. In this study, we show how extractive industries, especially large-scale mining, induced a cascade of land conversions which are affecting animal populations and pastoralists’ adaptive responses in northern Sweden. We examine social-ecological vulnerability in Arctic reindeer husbandry by integrating herders’ knowledge, population statistics for semi-domesticated reindeer Rangifer t. tarandus, public data on socio-economic variables and geospatial tools. We determine that approximately 34% of Laevas reindeer herding community’s grazing grounds are functionally unavailable to reindeer at present due to the accumulation of multiple competing land use pressures. Reindeer numbers currently only remain stable due to increased management efforts. Moreover, we identified current hotspots of high cumulative impact and mineral exploration as the spatially dominating land use factor in this area. Our approach and results provide new insights for scientifically robust cumulative impact assessments of anthropogenic stressors by creating a baseline of current developments via a combination of reindeer herder’s knowledge with historical data of trends and extents of human activity over the last century.
Snow is a critically important and rapidly changing feature of the Arctic. However, snow-cover and snowpack conditions change through time pose challenges for measuring and prediction of snow. Plausible scenarios of how Arctic snow cover will respond to changing Arctic climate are important for impact assessments and adaptation strategies. Although much progress has been made in understanding and predicting snow-cover changes and their multiple consequences, many uncertainties remain. In this paper, we review advances in snow monitoring and modelling, and the impact of snow changes on ecosystems and society in Arctic regions. Interdisciplinary activities are required to resolve the current limitations on measuring and modelling snow characteristics through the cold season and at different spatial scales to assure human well-being, economic stability, and improve the ability to predict manage and adapt to natural hazards in the Arctic region.Idag fokuserar jag mina tvärvetenskapliga forskningsprojekt på hur snabba förändringar i klimat och markanvändning påverkar fjällen och ger
ändrade förutsättningar för bland annat renskötseln. Tillsammans med forskare med kompetens inom klimatmodellering och miljö- och urfolksrätt, renskötare från flera samebyar och Svenska Samernas Riksförbund fokuserar vi nu på att ta fram förslag på hur konsekvenserna av klimatförändringarna bäst bedöms innan beslut om förändrad markanvändning fattas.

Vi forskar om förändringar i klimat och miljö, både bakåt i tiden och nutida förhållanden. Genom klimatmodeller vill vi sedan simulera framtida klimat- och miljöförändringar.
Laboratory experiments and point observations, for instance in wetlands, have shown evidence that microbial sulfate reduction (MSR) can lower sulfate and toxic metal concentrations in acid mine drainage (AMD). We here hypothesize that MSR can impact the fate of AMD in entire catchments. To test this, we developed a sulfur isotope fractionation and mass-balance method, and applied it at multiple locations in the catchment of an abandoned copper mine (Nautanen, northern Sweden). Results showed that MSR caused considerable, catchment-scale immobilization of sulfur corresponding to a retention of 27 ± 15% under unfrozen conditions in the summer season, with local values ranging between 13 ± 10% and 53 ± 18%. Present evidence of extensive MSR in Nautanen, together with previous evidence of local MSR occurring under many different conditions, suggest that field-scale MSR is most likely important also at other AMD sites, where retention of AMD may be enhanced through nature-based solutions. More generally, the developed isotope fractionation analysis scheme provides a relatively simple tool for quantification of spatio-temporal trends in MSR, answering to the emerging need of pollution control from cumulative anthropogenic pressures in the landscape, where strategies taking advantage of MSR can provide viable options.

Climate in the Arctic has warmed at a more rapid pace than the global average over the past few decades leading to weather, snow, and ice situations previously unencountered. Reindeer herding is one of the primary livelihoods for Indigenous peoples throughout the Arctic. To understand how the new climate state forces societal adaptation, including new management strategies and needs for preserved, interconnected, undisturbed grazing areas, we coupled changes in temperature, precipitation, and snow depth recorded by automatic weather stations to herder observations of reindeer behaviour in grazing areas of the Laevas Sami reindeer herding community, northern Sweden. Results show that weather and snow conditions strongly determine grazing opportunities and therefore reindeer response. We conclude that together with the cumulative effects of increased pressures from alternative land use activities, the non-predictable environmental conditions that are uniquely part of the warming climate seriously challenge future reindeer herding in northern Sweden.Observational data show that climate in the Southern Ocean region is rapidly changing. However, past the instrumental period, our understanding of climate variability in the region is limited by a scarcity of highresolution palaeoclimate records. Alpine glaciers, present on many Southern Ocean islands, may provide such data because changes in their mass balance, extent and erosion rates often mark a response to climate shifts. Rock flour, the fine-grained fraction of the glacial erosion process, is suspended in meltwater streams and transferred into the sediments of downstream lakes, continuously recording glacier variations. Here, we utilize this relationship to present a reconstruction of the Late Holocene glacier history of subantarctic South Georgia, using sediments from the glacier-fed Middle Hamberg Lake. To fingerprint a glacial erosion/size signal, we used titanium counts, validated against changes in sediment density and grain size, allowing a continuous reconstruction of glacier variations over the past similar to 1250 years. Together with local moraine evidence and supporting evidence from other Southern Hemisphere glaciers on New Zealand and in Patagonia, our findings reveal a series of consecutively diminishing Late Holocene advances. In addition to a glacier maximum before 1250 cal a BP, these include a twostage Litle Ice Age with advances around 300 and 120 cal a BP, in line with evidence from southern Patagonia. In addition, we present evidence for an unreported retreat behind present limits around 500 cal BP.

An emerging solution in mine waste remediation is the use of biological processes, such as microbial sulfate reduction (MSR), to immobilize metals, reducing their bioavailability and buffering the pH of acid mine drainage. Apart from laboratory tests and local observations of natural MSR in, for example, single wetlands, little is known about spatiotemporal characteristics of freshwater MSR from multiple locations within entire hydrological catchments. We here applied an isotopic fractionation (δ34S values in SO42−) and a Monte Carlo-based mixing analysis scheme to detect MSR and its variation across two major mining regions (Imetjoki, Sweden and Khibiny, Russia) in the Arctic part of Europe under different seasonal conditions. Results indicate a range of catchment-scale MSR values in the Arctic of ∼5%–20% where the low end of the range was associated with the non-vegetated, mountainous terrain of the Khibiny catchment, having low levels of dissolved organic carbon (DOC). The high end of the range was related to vegetated conditions provided by the Imetjoki catchment that also contains wetlands, lakes, and local aquifers. These prolong hydrological residence times and support MSR hot spots reaching values of ∼40%. The present results additionally show evidence of MSR persistence over different seasons, indicating large potential, even under relatively cold conditions, of using MSR as part of nature-based solutions to mitigate adverse impacts of (acid) mine drainage. The results call for more detailed investigations regarding potential field-scale correlations between MSR and individual landscape and hydroclimatic characteristics, which, for example, can be supported by the isotopic fractionation and mixing scheme utilized here.Jag är professor i geografi, med naturgeografisk inriktning och forskar om effekter av klimatförändringar i alpina och polära miljöer med fokus på snö, glaciärer och vatten.

Especially in the Arctic, knowledge gaps remain regarding the long-term mine waste impacts, such as metal leakage, on water quality. We study the small copper (Cu) mines of Nautanen, northern Sweden, which had been in operation for only six years when abandoned approximately 110 years ago in 1908. Measurements from field campaigns in 2017 are compared to synthesized historical measurement data from 1993 to 2014, and our results show that concentrations of Cu, Zn, and Cd on-site as well as downstream from the mining site are order(s) of magnitude higher than the local background values. This is despite the small scale of the Nautanen mining site, the short duration of operation, and the long time since closure. Considering the small amount of waste produced at Nautanen, the metal loads from Nautanen are still surprisingly high compared to the metal loads from larger mines. We argue that disproportionately large amounts of metals may be added to surface water systems from the numerous small abandoned mining sites. Such pollution loads need to be accounted for in sustainable assessments of total pollutant pressures in the relatively vulnerable Arctic environment. 2008. Laura Cunningham (et al.). European Climate of the Last Millennium, Millennium Milestone meeting 2, Cala Millor, Mallorca, 13th-15th March 2008, 80-81Here we present a lake sediment study from west central Sweden that covers the last thousand years. The study site Lake Spåime is a shallow, hydrologically open lake situated above the present tree line. We applied chironomid analysis with the aim to reconstruct mean July air temperature at a high temporal resolution and we evaluated our reconstruction with significance tests and comparison with observed meteorological data. We examined the relationship between changes in chironomid-inferred July temperature, isotope hydrology and minerogenic detrital input. We also assessed the influence of running water and semi-terrestrial/terrestrial chironomids. The inferred July air temperatures ranged from 8.5˚C to 11.6˚C (mean 9.6˚C) over the past millennium. The temperatures inferred with running water- and terrestrial taxa removed was similar, but with a 0.6 ˚C higher amplitude. The results of significance testing were inconclusive. Comparison with meteorological data showed that the chironomid-based July air temperatures were similar during the last 110 years. Individual years when chironomid-inferred July air temperatures were lower than the instrumental data were characterized by low June air temperatures and high amounts of winter precipitation. From this, we assume that late snowmelt led to cool melt water input in July which in turn caused a decoupling between water and air temperatures causing too low inferred temperatures. Inferred July temperatures show similarities and discrepancies with reconstructions derived from other proxies in the region, such as tree-ring and sea surface temperature records, and fail to reconstruct the cold summer conditions characteristic of the years between AD 1650 and 1750. We conclude that the Spåime July temperature reconstruction was partly biased, possibly because of major changes in the Spåime catchment system that influenced the chironomids. For example, changes in hydrology caused by shifts in seasonality and amount of precipitation may have triggered changes in sediment erosion and deposition rates, affecting the chironomid composition to a larger extent than mean July air temperatures. Future challenges include examination of the temperature sensitivity of chironomid taxa and continued critical assessment of individual chironomid inferred temperature reconstructions, not only against other temperature proxies but also against proxies for variations in hydrology. In Arctic alpine regions, glacio-lacustrine environments respond sensitively to variations in climate conditions, impacting, for example,glacier extent and rendering former ice-contact lakes into ice distal lakes and vice versa. Lakefloors may hold morphological records of past glacier extent, but remoteness and long periods of ice cover on such lakes make acquisition of high-resolution bathymetric datasets challenging. Lake Tarfala and Kebnepakte Glacier, located in the Kebnekaise mountains, northern Sweden, comprise a small, dynamic glacio-lacustrine system holding a climate archive that is not well studied. Using an autonomous surface vessel, a high-resolution bathymetric dataset for Lake Tarfala was acquired in 2016, from which previously undiscovered end moraines and a potential grounding line feature were identified. For Kebnepakte Glacier, structure-from-motion photogrammetry was used to reconstruct its shape from photographs taken in 1910 and 1945. Combining these methods connects the glacial landform record identified at the lakefloor with the centennial-scale dynamic behaviour of Kebnepakte Glacier. During its maximum 20(th) century extent, attained c. 1910, Kebnepakte Glacier reached far into Lake Tarfala, but had retreated onto land by 1945, at an average of 7.9 m year(-1). We studied the variability of elemental carbon (EC) over 3 years (2009-11) in the winter snowpack of Storglaciaren, Sweden. The goal of this study was to relate the seasonal variation in EC to specific snow accumulation events in order to improve understanding of how different atmospheric circulation patterns control the deposition of EC. Specifically, we related meteorological parameters (e.g. wind direction, precipitation) to snow physical properties, EC content, stable-isotope 8180 ratios and anion concentrations in the snowpack. The distribution of EC in the snowpack
varied between years. Low EC contents corresponded to a predominance of weather systems originating in the northwest, i.e. North Atlantic. Analysis of single layers within the snowpacks showed that snow layers enriched in heavy isotopes coincided predominantly with low EC contents but high chloride and sulfate concentration. Based on this isotopic and geochemical evidence, snow deposited during these events had a strong oceanic, i.e. North Atlantic, imprint. In contrast, snow layers with high EC content coincided with snow layers depleted in heavy isotopes but high anion concentrations, indicating a more continental source of air masses and origin of EC from industrial emissions.In this article, we present results from a palaeolimnological study from Lake Vuoksjavratje in the mountain tundra region in the Vindelfjallen Mountains, northwest Sweden. We suggest that the influence of precipitation may be one of the factors causing discrepancies between chironomid-based late-Holocene July temperature (JulyT) reconstructions from Fennoscandia. We combine quantitative temperature reconstruction using chironomids for the last 5100 years with qualitative analysis of chironomid composition and geochemical analyses, such as x-ray fluorescence (XRF), total organic carbon (TOC) and C/N analysis. The studied sequence is dated by Pb-210, Cs-137 and 11 C-14 datings from terrestrial macrofossils. The aim of the study was to use chironomids to reconstruct late-Holocene summer temperature variation on a multi-centennial to centennial timescale and to use geochemical data to identify periods during which the changes in chironomid composition might have been forced by environmental variables other than temperature, such as within lake processes or precipitation. Based on ordination techniques, and a comparison between chironomid-inferred JulyTs and changes in minerogenic sedimentation with regional temperature and wetness records, it is concluded that the JulyT signal was modulated by precipitation. The proxies indicate that both JulyT and annual precipitation have influenced the chironomid communities in Lake Vuoksjavratje, and that catchment-related processes caused by enhanced precipitation have overridden the summer temperature signal between 3000 and 2200 cal. yr BP, and between 1050 and 100 cal. yr BP.

Understanding the impacts of extractive industries on sustainable development requires analyzing them as part of dynamic social-ecological-technological systems. Building on insights from studies of social-ecological systems and socio-technical systems, as well as fieldwork on the impacts of mining in the Nordic Arctic, this article presents an analytical framework for co-production of knowledge about the role of industrial or infrastructure projects for regional development. We use this framework to analyze Swedish mining policy, assessment guidelines, and environmental impact assessments for three mining projects in Arctic Sweden. We conclude that Swedish mining policy and guidelines for impact assessments neglect key aspects of social-ecologicaltechnological systems, including the impacts of climate change, and treat many social aspects of sustainable development in a cursory manner. We suggest that more systematic analysis of the dynamics of social-ecologicaltechnological systems would facilitate more transparent decision making and help identify the potential role of proposed mining projects in pathways towards sustainable development in northern regions.
Waters from high-altitude alpine lakes are mainly recharged by meteoric water. Because of seasonal variations in precipitation and temperature and relatively short hydraulic residence times, most high-altitude lakes have lake water isotopic compositions (delta O-18(lake)) that fluctuate due to seasonality in water balance processes. Input from snowmelt, in particular, has a significant role in determining lake water delta O-18. Here we compare two high-resolution delta O-18(diatom) records from lake sediments in the Swedish Scandes with instrumental data from the last century obtained from nearby meteorological stations. The time period AD 1900-1990 is characterised by an increase in winter precipitation and high winter/summer precipitation ratios and this is recorded in delta O-18(diatom) as decreasing trends. Lowest delta O-18(diatom) values and highest amount of winter precipitation are found around AD 1990 when the winter North Atlantic Oscillation index was above +2. We conclude that for the last 150 a the main factor affecting the delta O-18(diatom) signal in these sub-Arctic high-altitude lakes with short residence times has been changes in amount of winter precipitation and that delta O-18(diatom) derived from high-altitude lakes in the Swedish Scandes can be used as a winter precipitation proxy.Stable isotopes (O and C) of lacustrine carbonates (Chara spp algae and Pisidium spp molluscs) from a lake sedimentary sequence in central Sweden were analysed to infer changes in lake hydrology and climate during the late Holocene. Results from analysis of lake water isotopes (O and H) show that Lake Blektjärnen water isotope composition is responsive to the water balance between evaporation and input water (E/I ratio). A high E/I ratio results from a dry and probably warmer climate, decreasing the relative importance of precipitation input. Under such conditions evaporation and atmospheric equilibration enrich lake water in O and C, respectively, which is reflected in the isotopic composition of the carbonates in the lake. From the relatively positive Chara O values we infer that conditions were dry and warm between 4400-4000 cal yr BP whereas more negative values indicate that conditions were wetter and probably cooler between 4000-3000 cal yr BP. A drier climate is inferred from more positive values between 2500-1000 cal yr BP. However, a successive depletion after ca 1750 cal yr BP, also detected in several other O records (carbonate and diatom), suggest increasingly wetter conditions in Scandinavia after that time, which is probably related to increased zonal flow.

In this study, summer rainfall contributions to streamflow were quantified in the sub-arctic, 30% glacierized Tarfala (21.7km(2)) catchment in northern Sweden for two non-consecutive summer sampling seasons (2004 and 2011). We used two-component hydrograph separation along with isotope ratios (O-18 and D) of rainwater and daily streamwater samplings to estimate relative fraction and uncertainties (because of laboratory instrumentation, temporal variability and spatial gradients) of source water contributions. We hypothesized that the glacier influence on how rainfall becomes runoff is temporally variable and largely dependent on a combination of the timing of decreasing snow cover on glaciers and the relative moisture storage condition within the catchment. The results indicate that the majority of storm runoff was dominated by pre-event water. However, the average event water contribution during storm events differed slightly between both years with 11% reached in 2004 and 22% in 2011. Event water contributions to runoff generally increased over 2011 the sampling season in both the main stream of Tarfala catchment and in the two pro-glacial streams that drain Storglaciaren (the largest glacier in Tarfala catchment covering 2.9km(2)). We credit both the inter-annual and intra-annual differences in event water contributions to large rainfall events late in the summer melt season, low glacier snow cover and elevated soil moisture due to large antecedent precipitation. Together amplification of these two mechanisms under a warming climate might influence the timing and magnitude of floods, the sediment budget and nutrient cycling in glacierized catchments.
Here we present delta P-18(diatom) data from two high-latitude lakes; one has short residence time and a water isotopic composition (delta O-18(lake)) that fluctuate due to seasonal variations in precipitation and temperature, and the other has delta O-18(lake) that is influenced by longer lake water residence times and evapor
ation. The delta O-18(diatom) records reveal common responses to precipitation forcing over the past millennium. Relatively wet summers are inferred from delta O-18(diatom) between 1000 and 1080 AD, 1300 and 1440 AD, and during the early 19th century, coincided with periods of high cloud cover inferred from tree-ring carbon isotopes, and other data for high Arctic Oscillation index. While relatively dry summers with increasing influence of winter snow are indicated between 1600 and 1750 AD. The co-response between carbon isotopes in trees and oxygen isotopes in diatoms strengthens the relationship between cloud cover and precipitation and the hypothesis that these changes were the result of significant regional shifts in atmospheric circulation.Reindeer and reindeer herders in the circumpolar North are exposed to harsh and often hard-to-predict weather conditions. Herding communities have previously adapted to these external disturbances by flexible pasture use, seasonal mobility, changing herding practices, diversifying livelihoods and continuously developing traditional or experience-based knowledge. However, few places in the world experience ongoing climate change as clearly and rapidly as the high northern latitudes. The effects of climate change and increased frequency of extreme weather events are transforming the biophysical environment of reindeer husbandry. These changes challenge the adaptive capacity of herders who operate in a landscape they share with, and which is highly impacted by, other forms of land use. Thus, sociopolitical factors play a major role in developing adaptation strategies that are perceived as desirable and possible. This chapter summarizes the observed and expected changes in climate and impacts thereof within the reindeer herding area (RHA) of northern Fennoscandia. The chapter further presents a range of strategies adopted by herders to cope with adverse, seasonal weather conditions and indirect impacts of climate change. Finally, it situates these strategies in the context of more proactive and institutional adaptation.

Snow particle size is an important parameter strongly affecting snow cover broadband albedo from seasonally snow covered areas and ice sheets. It is also important in remote sensing analyses because it influences the reflectance and scattering properties of the snow. We have developed a digital image processing method for the capture and analysis of data of snow particle size and shape. The method is suitable for quick and reliable data capture in the field. Traditional methods based on visual inspection of samples have been used but do not yield quantitative data. Our method provides an alternative to both simpler and more complex methods by providing a tool that limits the subjective effect of the visual analysis and provides a quantitative particle size distribution. The method involves image analysis software and field efficient instrumentation in order to develop a complete process-chain easily implemented under field conditions. The output from the analysis is a two-dimensional analysis of particle size, shape, and distributions for each sample. The results of the segmentation process were validated against manual delineation of snow particles. The developed method improves snow particle analysis because it is quantitative, reproducible, and applicable for different types of field sites.Lacustrine sediments are often used for paleoclimate reconstructions as continuous archives of several physical and biological proxies. The relation between autochthonous and allochthonous sedimentation in alpine lakes is a complex system that may cause difficulties when interpreting biological and physical parameters. Results from previous studies of alpine lakes in northern Sweden have demonstrated that non-glacial processes produce minerogenic lake deposits with similar physical characteristics (density, LOI, magnetic susceptibility, grain-size) as those that have been associated with glacier fluctuations in proglacial lakes. In this study of two consecutive proglacial alpine lakes we show that fluvial redeposition of alluvial fan deposits significantly affects the Holocene lake sedimentation. Depending on the geomorphological setting, such fluvial redeposition signals may actually overprint a glaciofluvial signal. We also show that minerogenic laminations of fluvial origin are impossible to separate from the type of laminations usually used to infer glacier activity using the most common lithological sediment parameters. This emphasizes the complexity of sediment transport system in proglacial (paraglacial) settings where redeposition of older glacial sediment is of major importance. Our results highlight the need for thorough understanding of the geomorphological setting before inferences are made about climate variations from sedimentation in alpine lakes. moth lakes in this study contain sediment sequences with both episodic (turbidites) and continuously deposited sediments. Unfortunately we have too few radiocarbon dates to exactly date the turbidites but it is clear that turbidite layers in any case should be excluded from age model constructions since episodic sedimentation significantly influences the sediment age-depth relationship. In our age-model turbidites cause a potential dating error of several hundred, up to a thousand, years.

Over 11 000 L of kerosene was deposited on the surface of Rabots glaciar on the Kebnekaise Massif, northern Sweden, following the crash of a Royal Norwegian Air Force aircraft in March 2012. An environmental monitoring programme was subsequently commissioned, including a series of dye tracing experiments during the 2013 melt season, conducted to investigate the transport of pollutants through the glacier hydrological system. This experimental set-up provided a basis from which we could gain new insight into the internal hydrological system of Rabots glaciar. Results of dye tracing experiments reveal a degree of homogeneity in the topology of the drainage system throughout July and August, with an increase in efficiency as the season progresses, as reflected by decreasing temporary storage and dispersivity. Early onset of melting likely led to formation of an efficient, discrete drainage system early in the melt season, subject to decreasing sinuosity and braiding as the season progressed. Four distinct meltwater flow regimes are identified to summarize the temporal and spatial evolution of the system. Analysis of turbidity-discharge hysteresis further supports the formation of discrete, efficient drainage, with clockwise diurnal hysteresis suggesting easy mobilization of readily available sediments in channels. Dye injection immediately downstream of the pollution source zone reveals prolonged storage of dye followed by fast, efficient release. Twinned with a low dye recovery, and supported by sporadic detection of hydrocarbons in the proglacial river, we suggest that meltwater, and thus pollutants in solution, may be released periodically through an efficient, and likely pressurized, hydrological system within the upper reaches of the glacier.

In MMA we have two hands, two feet, two knees, two elbows plus all the outcomes that can happen based off a takedown. It’s a lot of things and I’ve been feeling from like 34 to 37 that in that department and solely in that department my reflexes and reaction time took a big dip. It’s not where it used to be when I was 35 even.

Genom att dagligen täcka världens snabbast växande sport med bra artiklar, intressanta reportage och högklassiga produktioner tror vi att vårt mål bäst uppnås. Kimura.se är oberoende och drivs av ett gäng eldsjälar som brinner för sporten.
Here’s the honest truth. I’m still fast, I’m still explosive, I have good endurance. I know so much more about the sport than when I started. There’s just a couple things that as you get older slow down. That’s like the overload sensory from [head] to [heart] and my body doing it. Matchen var Masvidals 52:a i en karriär där han stod för 35-17 i record och han förblir en gigantisk profil inom MMA-världen trots att han inte längre är aktiv. 38-åringen kommer nu fokusera på sin roll som promoter och ägare av kampsportsorganisationerna Gamebred FC och Gamebred Boxing. Men även om planen nu är att vara aktiv utanför buren så kommer Masvidal aldrig säga aldrig. Masvidals främsta period i karriären var utan tvekan segersviten under 2019 där han blev en av sportens allra absolut största stjärnor. Detta när han tog tre raka dominanta segrar via avslut. Först knockade han Darren Till inför dennes hemmapublik i London och han avslutade med att besegra stjärnan Nate Diaz på legendariska Madison Sqaure Garden via TKO. Mellan dessa så kom det mest oförglömliga ögonblicket dock när han knockade den då obesegrade Ben Askren via otroligt spektakulärt flygande knä efter endast 5 sekunder av matchen.Förra månaden på hemmaplan vid UFC 287 valde Masvidal att lägga handskarna på hyllan efter sin fjärde raka förlust efter en tapper insats mot toppfightern Gilbert Burns där denne till slut vann via tydligt enhälligt domslut.

I’ll never say like, ‘I’ll never come back’ because I love this sport so much. I have so many great memories that just fill me and will stay with me forever about this sport. So, I’ll never say I can’t come back.
Även i sina två senaste förluster mot hatobjektet Colby Covington och den tidigare nämnde Burns visade Masvidal glimtar av det som gjorde honom till en absolut toppfighter men väl medveten om den nivå där han fightades på så känner inte Masvidal att det är värt att fortsätta om han inte kan besegra dem bästa:
