Studies on the Presence and Spatial Distribution of Anthropogenic Pollution in the Glacial Basin of Scott Glacier in the Face of Climate Change (Fiord Bellsund, Spitsbergen)
PublikacjaThe study area covered the NW part of the Wedel Jarlsberg Land (SW part of the Svalbard Archipelago). The primary study object was the catchment of the Scott Glacier in the vicinity of the Research Station of of Maria Curie-Skłodowska University in Lublin – Calypsobyen. The Scott River catchment (of glacial hydrological regime) has an area of approximately 10 km2, 40% of which is occupied by the valley Scott Glacier in the phase...

Impact of Climate Change on a Runoff Formation in Seaside Catchment Area on the Example of the Babica River Catchment
PublikacjaThe paper presents the impact of taking into account climate change in the perspective of 2050 on the results of hydrological calculations of characteristic flows in the hydrographically diverse seaside catchment area on the example of the Babica river catchment. A mathematical model of the Babica river catchment was made in the HEC-HMS program. The SCS method was used. The outflow from the basin was analysed for waters with...

Chemical hazard in glacial melt? The glacial system as a secondary source of POPs (in the Northern Hemisphere). A systematic review
PublikacjaToxicity of compounds belonging to persistent organic pollutants (POPs) iswidely known, and their re-emission from glaciers has been conclusively demonstrated. However, the harmful effects associated with such secondary emissions have yet to be thoroughly understood, especially in the spatial and temporal context, as the existing literature has a clear sampling biaswith the best recognition of sites in the European Alps. In this...

Characteristics of the Radunia river and its catchment in view of WFD
PublikacjaCelem Ramowej Dyrektywy Wodnej (RDW), między innymi problemami jest ochrona śródlądowych wód powierzchniowych, zabezpieczenie przed dalszym pogorszenien ich stanu i poprawa stanu ekosystemów wodnych. Badania Rzeki Raduni i jej zlewni zostały wykonane przez Instytut Budownictwa Wodnego i Politechnikę Gdańską. Dotyczyły one wód śródlądowych (rzeki, jeziora, zbiorniki), ich hydrologii, hydrauliki i jakości wody. Rzeka jest istotna...

Abundance and biomass of bacteria in two Arctic glacial fjords
PublikacjaTotal numbers and biomass of bacterioplankton in water in two glacial fjords off west Spitsbergen have been studied. Samples were collected from different water depth layers - from the surface to 80-90 m. Total bacterial number (TBN), biomass and morphological structure were determined by the acridine orange direct count method. The highest values of TBN and biomass in the water column were found on stations situated adjacent...

Release and Transport of Toxic, Mobile Organic Compounds (Formaldehyde and Phenols) on an Arctic Glacier
PublikacjaAs a result of current deglaciation, the chemical cycles of many compounds, including toxic formaldehyde and phenols, are changing. However, the processes by which these chemicals are released have yet to be studied in situ. Here, we quantify fluxes of HCHO and phenols in a glacial catchment within one summer season, obtaining a net release from the glacier of 0.106 · 106 g formaldehyde and 0.255 · 106 g phenols, which can be interpreted...

Aluminium in glacial meltwater demonstrates an association with nutrient export (Werenskiöldbreen, Svalbard)
PublikacjaThe aluminium (Al) cycle in glacierised basins has not received a great deal of attention in studies of biogeochemical cycles. As Almay be toxic for biota, it is important to investigate the processes leading to its release into the environment. It has not yet been ascertained whether filterable Al (passing through a pore size of 0.45 m) is incorporated into biogeochemical cycles in glacierised basins. Our study aims to determine...
