Modelling dispersal of juvenile krill released from the Antarctic ice edge: Ecosystem implications of ocean movement

We develop a hypothesis, based on historical observations, that surface krill patches composed of juvenile krill move passively with ocean currents after their release from the sea ice edge zone in spring. Applying this hypothesis and method to the Southern Hemisphere spring/summer, leads to results that indicate that the observed changes in distribution of krill patches from historical to contemporary records could be related to the southward shift of the sea ice edge over the last century.
