 Time to Krill? crucial antarctic ecosystem threatened
Antarctic krill are mainly herbivorous feeding on the phytoplankton (microscopic suspended plants) of the Southern Ocean but planktonic animals (zooplankton) may also form a part of their diet.
It is the aggregating nature of krill that has enabled the baleen whales to evolve their feeding habits; if krill were any less dense, great whales would not be able to filter enough water to strain out sufficient prey, and their great size attests to the abundance of krill.
Although the fishery for Antarctic krill is not turning out to be the cornucopia that many had imagined, it is also not turning out to be the environmental scourge that it had the potential to be; in fact, it may end up being the agent for the restoration of the Antarctic ecosystem.

 Annual Report 2002 - Dynamics of Overwintering Antarctic Krill Populations   (Site not responding. Last check: 2007-10-16)
Adult krill constitute a large fraction of the zooplankton biomass in key areas and often occur in very large numbers massed in intense patches and swarms ranging in size from a few tens of square meters to tens of square kilometers.
During the relatively ice-free fall cruise, krill adults and larvae were distributed principally in the upper 200 meters (660 feet) of the water column.
Large numbers of larval krill, however, were observed only in regions where the ice undersurface was highly irregular as a result of the ridging and down thrusting caused by ice sheet collision and compaction during violent winter storms.

In a study that may demystify parts of the Antarctic food web, Andrew Brierley and colleagues from the British Antarctic Survey report in the March 8 issue of Science that krill, which are surface-dwelling, shrimp-like creatures, are concentrated under Antarctic sea ice in a band just south of the line between open water and ice.
The Antarctic krill distribution patterns the submarine discovered confirm that the most popular whale hangouts along the sea-ice edge are places with the highest concentrations of krill, and highlight the sea-ice edge as important terrain for Antarctic ocean dwellers.
Using this information, Brierley and colleagues found that krill were five times more abundant within a thick band as large as thirteen kilometers under the sea ice than in the open ocean.
