Summary: | During two expeditions of the R.V. “Polarstern” to the Arctic Ocean, pack ice and under-ice water samples were collected during two different seasons: late summer (September 2002) and late winter (March/April 2003). Physical and biological properties of the ice were investigated to explain seasonal differences in species composition, abundance and distribution patterns of sympagic meiofauna (in this case: heterotrophs >20 µm). In winter, the ice near the surface was characterized by extreme physical conditions (minimum ice temperature: -22°C, maximum brine salinity: 223, brine volume: <=5%) and more moderate conditions in summer (minimum ice temperature: -5.6°C, maximum brine salinity: 94, most brine volumes: >=5%). Conditions in the lowermost part of the ice did not differ to a high degree between summer and winter. Chlorophyll a concentrations (chl a) showed significant differences between summer and winter: during winter, concentrations were mostly <1.0 µg chl a/l, while chl a concentrations ... : Supplement to: Schünemann, Henrike; Werner, Iris (2004): Seasonal variations in distribution patterns of sympagic meiofauna in Arctic pack ice.
