NERC EDS UK Polar Data Centre. https://doi.org/10.5285/0826a8a0-e9c5-4504-8f75-a7516041c282 Acoustic backscatter data were collected on board the RRS James Clark Ross during cruise JR17002 on 20/01/2018 in Bransfield Strait and the caldera of Deception Island. Data were collected using a Simrad EK60 echosounder at 38, 70, 120 and 200 kHz. The EK60 was calibrated on 07/01/2018 in Stromness Harbour, South Georgia. More information about the calibration can be found in the Cruise Report for JR17002. This work was carried in the frame of the Polar Ocean Ecosystem TimeSeries - Western Core Box (POETS-WCB) project.

Each data file contains approximately 10 minutes of data and is approximately 26 MB in size. Each data file contains raw ping data with associated GPS fixes and date/time. In order to process the data, 3 files in the TOML syntax language are supplied: - transect file (defines the start and end times for a given transect, list the raw and environmental files making up the transect, and references to associated metadata and calibration files) - water column active acoustic metadata file (compliant with ICES. 2016, a metadata convention for processed acoustic data from active acoustic systems, SISP 4 TG-AcMeta Version 1.10, ICES WGFAST Topic Group, TG-AcMeta. 47 pp.) - calibration file (calibration data and metadata ((compliant with ICES. 2016, a metadata convention for processed acoustic data from active acoustic systems, SISP 4 TG-AcMeta Version 1.10, ICES WGFAST Topic Group, TG-AcMeta. 47 pp.) Data collection: Data were collected using a Simrad EK60 echosounder at 38, 70, 120 and 200 kHz. Data quality: Raw data (time, gps and acoustic) are not quality checked. The instrument was calibrated on 07/01/2018 in Stromness Harbour, South Georgia. asNeeded completed
