Vertical distribution and seasonal variation in ice algae biomass in coastal sea ice off Zhongshan Station, East Antarctica
The biomass of ice algal communities in coastal sea ice off Zhongshan Station, Antarctica were monitored from April to December 1992. The maximum thickness of ice cover was 1.74 m in November/December and covered-snow was less than 35 cm in depth throughout the study period. Brown layers occurred in...
