Full description

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 EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information for a total of 3054 km primarily for surveying the bottom of the canyons in the sampling area and also in deep water >1000m on the transit back to Hobart.

The EM122 provides a 1 degree by 1 degree angular resolution. The echosounder's nominal frequency is 12 kHz.

Data are stored in *.all raw format for bathymetry and backscatter at CSIRO. There are 213 files totalling 7.46 GB of raw data in this dataset.

Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are 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 information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
