Circumpolar connections between Antarctic krill (Euphausia superba Dana) populations: Investigating the roles of ocean and sea ice transport
in the Southern Ocean. Krill have a close association with sea ice which provides access to a ... critical food source and shelter, particularly in the early life stages. Advective modelling of transport ... . Here we present Lagrangian modelling studies at the circumpolar scale that include interaction with sea ... ice. The advection scheme uses ocean velocity output from the Ocean Circulation and Climate Advanced ...
