| Summary: | Acoustic backscatter data were collected on board the RRS James Clark Ross (cruise JR161) as part of the Discovery 2010 programme. Data were collected using a Simrad EK60 echo sounder. This cruise ran two transects (Stanley to Signy and Signy to South Georgia) across the Scotia Sea in the austral spring (October - December) of 2006. Within these transects, three process stations and five condensed stations were undertaken. Acoustic transects were run at each of the stations, although the EK60 was also run continuously throughout the cruise. JR161 was the first of three cruises which comprise the field studies of the Discovery 2010 programme. The programme was designed to analyse interactions in the Southern Ocean ecosystem. The raw data files (Simrad .raw format) are held by the Polar Data Centre (PDC) at the British Antarctic Survey (BAS). : The dataset comprises Simrad raw format files that have not undergone any processing or quality checking. The EK60 was calibrated prior to data collection. Commercial software Echoview is required in order to process and analyse the data. https://www.echoview.com/ |
