dc.description.abstract

A number of common sterols were identified in sea ice diatoms from the Arctic and the Antarctic. The main sterols in floating sea ice algal aggregates collected from Resolute Passage (Canadian Arctic) and Nansen Basin (North Svalbard) in 2012 were 22E-dehydrocholesterol, cholesterol, epi-brassicasterol, 24-methylenecholesterol and 24-ethylcholesterol, although the distribution varied between the two locations, likely reflecting compositional differences in diatom taxa. The three major sterols in cells of Berkeleya adeliensis picked from a melted sea ice core collected from Ryder Bay in the Antarctic Peninsula in 2014, were 24-ethylcholesterol, cholesterol and 22E-dehydrocholesterol. We suggest that certain sea ice diatoms may thus contribute to the sedimentary budget of common sterols in seasonally sea ice-covered locations following ice melt.
