SNOW ALGAL COMMUNITIES ON ARCTIC PACK ICE FLOES DOMINATED BY CHLAMYDOMONAS NIVALIS (BAUER) WILLE (17th Symposium on Polar Biology)
The occurrence of algae on the surface of Arctic ice floes was studied during the expedition ARK VIII/3 with the German research icebreaker RV POLAR-STERN in summer 1991. The species Chlamydomonas nivalis (BAUER) WILLESCWSW KOL was observed on all ice floes sampled covering the central part of the A...

The occurrence of algae on the surface of Arctic ice floes was studied during the expedition ARK VIII/3 with the German research icebreaker RV POLAR-STERN in summer 1991.

At one location a red coloured snow patch contained 1.56-10^5 cells ml^<-1> melted snow of C. nivalis. Only akinetic cells were observed. They were coloured bright red and were mostly incorporated into mucilaginous aggregates together with lithogenic sediments.
