Melting sea ice for taxonomic analysis: a comparison of four melting procedures
The influence of four melting procedures on the taxonomic composition of the sea-ice algal community in Kobbefjord, south-west Greenland, was investigated in April 2008. Direct melting (at 4 and 20°C) was compared with melting in buffering seawater (with salinities of 10 and 30). The sea-ice algal c...

The influence of four melting procedures on the taxonomic composition of the sea-ice algal community in Kobbefjord, south-west Greenland, was investigated in April 2008.
