This record describes multibeam echosounder data collected on RV Investigator voyage IN2017_T02, 'Collaborative Australian Postgraduate Sea Training Alliance Network (CAPSTAN): Training the Next Generation of Marine Scientists'. The voyage took place between November 14 and November 26, 2017 departing from Fremantle (WA) and arriving in Hobart (TAS).

The Kongsberg EM710 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information. A total of 1,711 km was covered, primarily used for mapping the continental shelf and the top of the canyons within the sampling area in addition to being the primary sounder in shallow water.

The EM710 provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 70 to 100 kHz.

Data are stored in *.all raw format for bathymetry and backscatter at CSIRO. There are 164 files totalling 24.9 GB of raw data in this dataset.

Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format is corrected for motion and position.

Tide corrections were not applied to the processed data. Processed data had outliers removed. Processed line data are available in *.gsf and ascii format.

Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
