An Arctic char observed in a glacial Spitsbergen river

An anadromous Arctic char (male) was recorded in southwestern Spitsbergen, in a very muddy glacial river, in August 2008. This is apparently the first specimen of this species observed in such an unfavourable habitat in Svalbard. Arctic char (Salvelinus alpinus), the only freshwater native fish in Svalbard, is rather common (occurring in more than 100 lakes and watercourses) and is differentiat...

Assumption and realization of Arie catchment measuring system, Spitsbergen

Geoecosystems of polar areas are particularly sensitive to climate change. The fluctuations of mean annual temperatures of Svalbard areas recorded for many years and progressing glacier recession indicate unequivocally that the Arctic areas strongly react to long-term weather and climate changes. Energy released in the form of proglacial waters contributes considerably to the transformation of ...

Monothalamous foraminifera from West Spitsbergen fjords, Svalbard: a brief overview

During the 2004 summer season, 14 sediment samples were collected in Kongs− fjorden and Isfjorden, West Spitsbergen, from 6 down to 345 m water−depth (mwd). The samples yielded abundant assemblage of monothalamous foraminifera, belonging to almost 40 morphotypes. Our qualitative (>125 μm) and quantitative data (125–500 μm) allowed to distinguish three water−depth related assemblages in both Kon...
