Because walrus avoid ice - covered waters
where sea ice concentration is 80 % or greater, any heavy ice concentrations reduce the areal extent of walrus foraging habitat.
Sea ice extent is defined as the surface area enclosed by the sea ice edge (
where sea ice concentration falls below 15 %).

The team investigated the trajectories of
sea ice drifting in the ocean and saw a pattern of
ice — and hence water — flowing northward from the vast northern coast of Russia toward the middle of the Arctic Ocean,
where the radium
concentrations had increased.
As the BRT stated, «Research suggests that, during the time of whelping and nursing, bearded seals prefer areas
where the percent
concentration of
sea ice is > 25 %.
Top panels: 50 % annual
sea ice concentration (dashed blue line) and buoyancy fluxes,
where negative values (blue shading) are associated with
sea ice formation; note that these areas expand equatorward in the LGM simulation.
