Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2017_V05, Long-term recovery of trawled marine communities 25 years after the world’s largest adaptive management experiment, which departed Broome on the 11 October 2017 and returned to Henderson on the 10 November 2017.

The Kongsberg EM710 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter around the Northwest Shelf.

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 and *.wcd format for watercolumn backscatter at CSIRO. There are 1436 files totalling 177GB of raw *.all data and 483 water column *.wcd files totalling 438 GB of 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 applied to the processed data using GPS tides in CARIS 10.3. Processed data 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.
