Summary
Abstract: ---- 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.

Quality
CTD and Acoustics data have been quality controlled. The trawl data once resources are provided to complete laboratory analysis will be quality controlled.


Access Constraints
These data have been aggregated together with other acoustics data, and are available via the metadata record, 'AAD Hydroacoustics hard disks - data collected from Southern Ocean cruises 1993-2004' (AAD_Hydroacoustics_data).
