Full description

This record describes multibeam echosounder data collected on RV Investigator research charter, IN2015_C01, 'GAB deep water geological and benthic ecology program' which departed Hobart on the 25 October and returned to Port Lincoln on the 28 November. A short sea trial voyage (October 22 - 25, Hobart - Hobart) was undertaken prior to the charter. Data for those days is also included in this data set.

The Kongsberg EM710 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter.

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 65 files totalling 4.93 GB of raw 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 not applied to the processed data. 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.
