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.
