This record describes multibeam echosounder data collected on RV Investigator voyage IN2016_E01, 'East Tasman Plateau – key to unravelling the onset of the Antarctic Circumpolar Current/MNF Equipment Sea Trials,' which departed Hobart on the 17 August 2016 and returned to Hobart on the 22 August 2016.

The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information between Hobart and the Cascade Seamount.

The EM710 MKII provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 40 to 100 kHz.

Data are stored in *.all raw format for bathymetry and backscatter at CSIRO. There are 26 files totalling 1.24 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 has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry and backscatter grids in geotiff 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.
