For millennia humans have extracted biological and physical resources from the planet to sustain societies enable development of technology infrastructure. Growth in human population changing consumption patterns increased footprint on ecosystems their biodiversity, including fresh waters. Freshwater biodiversity face many threats it is now widely accepted that we are a crisis. One means protecting restoring freshwater better manage exploitation biota aggregate (e.g., sand, gravel,...
Abstract Although Greenland is a hub for climate science, the perceptions of Greenland’s predominantly Indigenous population have remained largely unstudied. Here we present two nationally representative surveys and show that Greenlanders are more likely than residents top oil-producing Arctic countries to perceive change happening about twice as personally experienced its effects. However, half unaware human-caused those who most affected appear be least aware. Personal experience awareness...
Arctic coasts constitute the critical interface between land and sea, are subject to rapid changes caused by a warming climate. Current trends throughout show increasing erosion trends, while other parts of coast experiencing prograding trends. Until now, vast majority our knowledge coastal evolution is confined site-specific studies with limited geospatial representation. Here, we present DeltaCAN, novel data set on locations Canadian deltas larger than 500 m in width derived visual...
ABSTRACT Natural resource mining is a vital global industry serving sectors such as construction, infrastructure and electronics. The negative impacts of mining, exacerbated by poor governance lax legislation, have detrimental consequences on the environment, especially in freshwater systems. Mining shown to disrupt hydrological regimes, sediment dynamics vegetation structure, which affect water quality, species composition overall ecosystem health. However, little known about extent...
Accelerated climate warming has caused the majority of marine-terminating glaciers in Northern Hemisphere to retreat significantly during 21st century. While glacier and changes mass balance are widely studied on a global scale, impacts deglaciation adjacent coastal geomorphology is often overlooked. We examined proglacial zones across period 2000-2020 provide complete GIS dataset new coastline released from glacial ice hemisphere that time as well lost due advance. identified total 2466...
Diversity and complexity of infections with Plasmodium falciparum were described from cross-sectional surveys in November-December 1996 6 villages the Usambara Mountains, Tanzania, where transmission ranged markedly 0.03 to 91 infective bites per individual year. Forty-eight samples, stratified for age parasite densities, examined each village (n = 288). Genotyping was performed by a nested PCR method using primers specific allele families genes merozoite surface protein 1 (msp-1) 2 (msp-2)....
Geological studies of past and present sea level rely on valid robust features marking in geological sections. Present sea-level markers around the upper shoreface to beachface transition are detected a beach-ridge plain formed microtidal regime. These identify specific relative levels at time formation. Ground-penetrating radar (GPR) data collected across youngest part system Feddet, Denmark compared with independent coastal morphological sedimentological active strand interpreted relation...
ABSTRACT Beach‐ridge systems are important geo‐archives providing evidence for past wave climate including catastrophic storm flood events. This study investigates the morphological impacts of 1872 Baltic on a beach‐ridge system (sandy spit) in south‐eastern Denmark and evaluates frequency extreme events area over longer time perspective. paper combines field studies morphology sedimentary deposits, historical maps, digital terrain model, ground‐penetrating radar profiles, luminescence...
Abstract Identification of sea-level proxies is important for reconstruction past variation. Methods reconstructing Holocene relative curves are crucial quantification the impact Greenland ice thickness variation on global sea level and vertical land movement. Arctic beach ridges constitute potential archives However, their surface morphology may have undergone modification since deposition due to freezing/thawing processes erosion, therefore not be trustworthy reconstruction. Therefore,...
Abstract Climate change will increase the duration of annual sea‐ice‐free periods and shift precipitation patterns across Arctic. Those factors are likely to erosion rates along its coasts. Large parts Arctic coast consist hard rock. However, glacial, deltaic, coastal sedimentary deposits occur in deglaciated areas isostatic uplift following glaciations has created beach ridge plains pocket beaches with coarse soft‐sediment cliffs. Hitherto, very little was known about spatial distribution,...
F lakket on the island of A nholt in D enmark is a cuspate foreland facing microtidal K attegat sea. It composed number beach ridges typically covered by dune sand and separated swales wetlands. OSL dating indicates that evolution began c. AD 1000. Foreland growth was punctuated major episode coastal reorganization leading to retreat 1800. Coastal led formation an erosion surface separates older higher‐lying beach‐ridge swale deposits from younger lower‐lying deposits. The palaeo‐sea level...
A wide range of delta morphologies occurs along the fringes Young Sound in Northeast Greenland due to spatial heterogeneity regimes. In general, regime is related catchment and basin characteristics (geology, topography, drainage pattern, sediment availability, bathymetry), fluvial discharges associated load, processes by waves currents. Main factors steering Arctic into are snow ice melt precipitation catchment, extreme events like glacier lake outburst floods (GLOFs). Waves subordinate...
