Seasonal Development of Ice Algae and its Prediction from Environmental Factors near Resolute, N.W.T., Canada
Development of ice algae growing at the bottom of first-year congelation sea ice near Resolute, N.W.T. (75°N) was studied 1984–86. Ice algae moved downwards 1.5 cm∙d −1 as the ice thickened. Biomass increased logarithmically with doubling times on the order of 4–8 d, reaching over 150 mg chlorophyll...
