Abstract
The comparison of sea ice signals preserved in surface sediments from the North Pacific realm indicates that the IP25 biomarker signal is most closely related to modern extension of winter sea ice. Diatom and dinoflagellate signals are less well constraint to the sea ice extent but may be indicative of presence/absence of sea ice at areal scale. Down-core mismatches between IP25 and diatom sea ice indicator occurrences can be explained by different mechanisms responsible for signal formation and signal biasing by selective diatom dissolution.
