Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2019_T03, "ORCA: Using the Investigator radar as a moving reference for the Australian operational radar network" which departed Darwin on the 23 December 2019 and returned to Henderson on the 2 January 2020.

The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter between Darwin and Henderson.

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 and *.wcd format for watercolumn backscatter at CSIRO. There are 258 *.raw files totalling 70.4 GB and 257 *.wcd files totalling 464 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.
