Water column acoustic data collected from 2016-09-26 to 2016-11-03 during cruise JR16001 in the Atlantic Ocean
Water column acoustic data collected in the Atlantic Ocean (from 2016-09-26 to 2016-11-03) during cruise JR16001.
Multi-frequency (38,120 and 200 kHz) acoustic data were collected using a Simrad EK60 echo sounder. The dataset comprises of calibrated and processed 38 kHz volume backscattering strength (Sv, dB re 1m-1). Data processing was undertaken using Echoview and Matlab. Processed netCDF data files are made available as part of the NERC Southern Ocean Network of Acoustics (SONA) and the EU MESOPP project.

Methodology:
Data were collected from a hull-mounted multi-frequency (38, 120 and 200 kHz) Simrad EK60 echosounder, in Simrad .raw format during cruise JR16001 on the RRS James Clark Ross (https://www.bodc.ac.uk/data/information_and_inventories/cruise_inventory/report/jr16001). Data were processed at the British Antarctic Survey, detailed in https://sona.aq/data/data-overview/
. Acoustic calibration constants were obtained during cruise JR16003, detailed in https://www.bodc.ac.uk/data/information_and_inventories/cruise_inventory/report/jr16003, and applied to the acoustic data in post processing. Post-processing was undertaken using Echoview and Matlab, using BAS-SONA processing suite, a modified version of the CSIRO-BASOOP processing suite.
Data collection:
Simrad EK60 echo sounder (38, 120 and 200 kHz)
Data quality:
Raw data (time, gps and acoustic) are not quality checked. A measure of quality control is given by the proportion of data retained after a sequence of filters within the processing chain. The sequence is: 1) manual removal; 2) impulse noise filter; 3) attenuated signal filter; 4) signal to noise ratio (https://sona.aq/data/data-overview/).
