(Table 1) Dissolved organic carbon, water temperature and conductivity in three subarctic ponds near Kilpisjärvi, North Finland, supplement to: Zellmer, Iris D; Arts, M; Abele, Doris; Humbeck, Klaus (2004): Evidence of sublethal damage in Daphnia (Cladocera) during exposure to solar UV radiation in subarctic ponds. Arctic, Antarctic, and Alpine Research, 36(3), 370-377

Iris D Zellmer, M Arts, Doris Abele & Klaus Humbeck
Daphnia was collected from five subarctic ponds which differed greatly in their DOC contents and, consequently, their underwater light (UV) climates. Irrespective of which Daphnia species was present, and contrary to expectations, the ponds with the lowest DOC concentrations (highest UV radiation levels) contained Daphnia with the highest eicosapentaenoic acid (EPA) concentrations. In addition, EPA concentrations in these Daphnia generally decreased in concert with seasonally increasing DOC concentrations.Daphnia from three of the ponds was also...

Occurrence of metazoans, and gut pigments and fatty acid composition of Acartia bifilosa in ice and under-ice water samples from Santala Bay, supplement to: Werner, Iris; Auel, Holger (2007): Environmental conditions and overwintering strategies of planktonic metazoans in and below coastal fast ice in the Gulf of Finland (Baltic Sea). Sarsia, 89(2), 102-116

Iris Werner & Holger Auel
A field study was conducted in Santala Bay with weekly samplings during February and March 2000. Ice thickness was 20-28 cm, snow cover 0-1 cm. The under‐ice water column was stratified with a cold (-0.3 - 0.2°C) and less saline (S = 2.1-4.9) interface layer. Concentrations of particulate organic carbon (0.5–5.8 mg POC/l) and algal pigments (0.3-18.2 µg chlorophyll a/l) were higher in the ice than in the water (0.2-0.5 mg POC/l, 1.6–7.1 µg chlorophyll...

Mean snow accumulation rate, and mean methane sulfonate, chloride and nitrate concentration in snow pits and firn cores of Dronning Maud Land, supplement to: Weller, Rolf; Traufetter, Fidan; Fischer, H; Oerter, Hans; Piel, Claudia; Miller, Heinz (2004): Postdepositional losses of methane sulfonate, nitrate, and chloride at the European Project for Ice Coring in Antarctica deep-drilling site in Dronning Maud Land, Antarctica. Journal of Geophysical Research, 109(D7)

Rolf Weller, Fidan Traufetter, H Fischer, Hans Oerter, Claudia Piel & Heinz Miller
We quantified postdepositional losses of methane sulfonate (MSA-), nitrate, and chloride at the European Project for Ice Coring in Antarctica (EPICA) drilling site in Dronning Maud Land (DML) (75°S, 0°E). Analyses of four intermediate deep firn cores and 13 snow pits were considered. We found that about 26 ± 13% of the once deposited nitrate and typically 51 ± 20% of MSA- were lost, while for chloride, no significant depletion could be observed in firn...

Gut content, fatty acid composition and metabolic rates of the amphipod Anonyx sarsi during POLARSTERN cruise ARK-XIX/1, ice station PS64/070-6, supplement to: Werner, Iris; Auel, Holger; Kiko, Rainer (2004): Occurrence of Anonyx sarsi (Amphipoda: Lysianassoidea) below Arctic pack ice: an example for cryo-benthic coupling? Polar Biology, 27(8), 474-481

Iris Werner, Holger Auel & Rainer Kiko
During a winter expedition to the western Barents Sea in March 2003, benthic amphipods of the species Anonyx sarsi were observed directly below pack ice. Only males and juveniles [16.0-37.0 mm long, 16.2-120.8 mg dry mass (DM)] were collected. Guts contained macroalgal fibres, fish eggs and flesh from large carrion. Amphipods had very low levels of total lipids (2.7-17.2% DM). Analysis of lipid biomarkers showed that some of the specimens had preyed on pelagic copepods....
