We quickly recognized that the ADCP profiles of backscatter intensity appeared to be well-correlated to vertical distributions of euphausiids, principally E.superba, but including Thysanoessa macrura. Zooplankton samples

From three seasonal investigations, it is clear that the marginal ice zone is an important habitat for E. superba. The pack ice serves as a nursery ground for larval and juvenile krill and offers protection from predator

We ended the experiment when we saw no swimming nauplii in the pressure vessels 18 hours after the eggs hatched in the 2liter jars. One potential problem in the small closed vials would be lack of oxygen. The oxygen conc
