Brief description

---- Public Summary from Project ----
This project is designed to provide an understanding of the interactions between krill, other zooplankton, the physical environment and the predators dependent on krill. This will directly address a number of pressing problems facing CCAMLR (the Commission for the Conservation of Antarctic Marine Living Resources) in its attempts to manage the krill fishery using an 'ecosystem approach'.

Expected outcomes:
As a result of logistic operations (i.e. diversion to Casey) the 29 days on site allocated to this work was reduced to 10 days. Hence only a fraction of the intended program of work was conducted.

Acoustics:
Acoustics data (for 38, 120, 200kHz) was collected for the top 250m of the water column for nine and a half of the planned 13 transects in our 60 x 60 nautical mile survey region.
