<p>Despite the fact that glaciers and ice sheets have been monitored for more than a century, knowledge on glacial biota remains poor. Cryoconite holes are water-filled reservoirs glacier’s surface one of most extreme ecosystems micro-invertebrates. Tardigrada, also known as water bears, common inhabitant cryoconite holes. In this paper we present novel data morphology, diversity, distribution role in food web tardigrades Arctic glaciers. From 33 sampled 6 Spitsbergen, 25 were found...

Global warming results in increasingly widespread wildfires, mostly Siberia, but also North America and Europe, which are responsible for the uncontrollable emission of pollutants, to High Arctic region. This study examines 11 samples rainfall collected August a coastal area southern Bellsund (Svalbard, Norway). It covers detailed analysis major ions (i.e., Cl−, NO3−, SO42−) elements Cu, Fe, Mn, Pb, Zn) Hybrid Single-Particle Langrarian Integrated Trajectory( HYSPLIT) backward air mass...

Abstract During last years an interest in the processes of transport and fate pollutants to polar regions located distantly from industrial centers, has significantly increased. The current analytical techniques enabling conducting studies prove that Arctic (in past considered as a pollution free area) have become area highly intensive anthropopresion. Svalbard archipelago stands out other due its specific environmental conditions geographic location, which results becoming reservoir...

Abstract Progressive climate change may have unpredictable consequences for the Arctic environment. Permafrost catchments off west coast of Svalbard, described as “thin” and “warm,” are particularly sensitive to change. The interdisciplinary research on hydrochemical response surface underground water functioning within a small permafrost catchment area focused determination impact meteorological conditions (temperature ( T ), precipitation P )) mean daily discharge Q lowering groundwater...

The expansion of glacier-free areas in polar regions favours the appearance lakes non-glaciated parts glacier basins. This paper presents differentiation organic compound concentrations fifty-four Arctic collected four locations (Logne Valley, vicinity Scott, Renard and Antonia glaciers). We cover meteorological measurements, chemical analysis sixteen dioxin-like compounds (Polycyclic Aromatic Hydrocarbons (PAHs)), formaldehyde (HCHO), sum parameters phenolic (∑phenols) dissolved carbon...

Abstract Permafrost regions are under particular pressure from climate change resulting in widespread landscape changes, which impact also freshwater chemistry. We investigated a snapshot of hydrochemistry various environments the lower Kolyma river basin (North‐East Siberia, continuous permafrost zone) to explore mobility metals, metalloids and non‐metals thaw. Particular attention was focused on heavy metals as contaminants potentially released secondary source permafrozen Yedoma complex....

During both winter and summer, Svalbard reindeer selectively feed on different types of vegetation that are not only a source nutritional value, but also place heavy metal accumulation. In the present study, content cadmium, chromium, copper, iron, lead, nickel, manganese, zinc in excrement was measured. The main aims were to determine seasonal several metals faeces, compare their values terms dietary preferences during year. Summer gathered along designated linear transect running through...

Persistent organic pollutants (POPs) are contaminants that may appear in polar regions. In present work surface water was collected from the main stream Fuglebekken basin. The precipitationsamples near area by Polish Polar Station Hornsund. investigationreveals results of analysis these samples for their total phenols, formaldehyde, TOC, PAHs and PCBs content. presence basin (thousands kilometers distant industrial centers) those compounds is testimony to fact transported over vast distances...

The shaping of surface water chemistry in the Svalbard Archipelago is strongly dependent on geology catchment and process long-range transport atmospheric pollutants (LRATP). It was found that dissolved trace elements Scott River, which characterized by a decreasing degree glaciation, were natural origin (i.a. weathering dissolution local geological substratum). exception Zn originated from LRATP. paper describe influence changes hydro-meteorological conditions presence seabird colony...

This study focuses on short-term monitoring of trace metals in the Svalbard archipelago. Short-term studies using lichen bioindicators are important because temporary changes metal levels mainly dependent air pollutants.

This paper is a preliminary attempt to assess the composition of pollutants in two different caldera lakes situated Indonesian Archipelago: Batur and Bratan. Both are characterized by largely physico-chemical regimes; Lake located an area that currently volcanically active, unlike Bratan Lake. The latter much smaller shallower than concentration equatorial unknown, impact both biological geothermal processes on their distribution requires attention. study shows concentrations cations (Na+,...

In the last three decades, pollutant concentrations reaching Arctic from temperate latitudes have been significantly reduced, changing character of "Arctic haze" occurring in winter and spring. However, climate change leads also to remobilisation pollutants secondary sources environment. The resulting atmospheric pollution may vary substantially space hence we add a potentially important location for studies air map high Arctic. We investigated anthropogenic particles characteristics...

The character of atmospheric pollution and its impact on surface waters may vary substantially in space, hence, we add a potentially important location for the studies air to map High Arctic. We have investigated anthropogenic particle characteristics selected persistent organic pollutant concentrations, priorly unmonitored Arctic (Svalbard), exposed climatic gradient. Single-particle analysis PM indicates that besides prevailing natural aerosol particles, ones were present. likely origin...

The research area was localized in the Indonesian Archipelago, at latitude of eight and nine degrees S on one Lesser Sunda group island provinces, Bali (563,3 km2). Two massive calderas (Mount Batur 1717 m above sea level.; Mount Sangiyang 2093 level) are most prominent landforms chain volcanic mountain ranges Island. Lake (17,18 km2) Spring (which part freshwater lake system Mt. caldera) also Danau Bratan (one unconnected lakes next to caldera), were selected for studies pollutants...
