Raw acoustic data collected by ship-borne EK60 echo sounder in Scotia Sea (Oct - Dec 2006)

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).
