This dataset contains processed acoustic backscatter data that reflect integrated density estimates for Antarctic krill (Euphausia superba). The acoustic backscatter data are from the Western Core Box (WCB), comprising 8 acoustic transects that span the shelf-break at South Georgia. The data were obtained from a time series of 22 cruises carried out between 1996/97 and 2019/20. Data were collected using either a Simrad EK500 or EK60 echo sounder by biological oceanographers working at the British Antarctic Survey under the Ecosystems scientific research programme and predecessor Discovery 2010 and Dynamo research programmes. Funding was provided by the NERC/BAS Antarctic, Logistic, Infrastructure (ALI) Science and predecessor Long Term Monitoring Science research programmes.

A shallow and deep mooring has been deployed in the Southern Ocean, north of South Georgia, during multiple marine cruises from October 2002 onwards. As part of a long-term monitoring and assessment of the status of the marine ecosystems in the region of South Georgia, known as the Western Core Box, measurements were made for sustained observations of zooplankton abundance and distribution in its environmental context. Standard datasets include profiles from a Conductivity-Temperature-Depth (CTD) analyser, and Acoustic Doppler Current Profiler (ADCP). Funding was provided by the Scotia Sea open-ocean observatory (SCOOBIES) project. Data Access is provided via the RELATED DATA SET METADATA links.
