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 EM122 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information for two periods between Broome and Henderson when water depths exceeded 500 meters.

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 28 files totalling 1.1 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 applied to the processed data using GPS tides in CARIS v10. 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 information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
