There is a very useful analysis of Antarctic climate in an article of David Brockett, 2005, «Antarctic katabatic winds».

Strong katabatic winds related to the ice sheets (shown tentatively as stippled black arrows), were probably responsible for ice - free polynya - type conditions off the major ice sheets, causing phytoplankton and sea - ice algae productivity recorded in cores PS2138 - 3 and PS2757 - 8 (for the region off the Greenland - Laurentide Ice Sheet no proof from sediment cores are available.

Such an extended ice sheet associated with strong katabatic winds should have caused polynya - like open - water conditions in front of the ice sheet (Fig. 5a), resulting in increased fluxes of phytoplankton, ice algae and terrigenous matter as observed in the PS2757 - 8 record (Fig. 2c and Fig. 6, Scenario 2), i.e., a situation similar to that proposed for the Barents Sea continental margin (Fig. 5a) 57, 58.
