Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2019_v06, titled 'Tropical observations of atmospheric convection, biogenic emissions, ocean mixing, and processes generating intra-seasonal SST variability' which departed Darwin on the 19th of October 2019 and returned to Darwin on the 17th of December 2019 ,consisting of two legs.

Leg 1 - Darwin, 20:00, 19 October 2019 to Darwin, 19:00, 10 November 2019
Leg 2 - Darwin, 20:00, 11 November 2019 to Darwin, 08:00, 17 December 2019

The Kongsberg EM710 multibeam echosounder was used to acquire seafloor bathymetry and backscatter information around the Northwest Shelf station (121.5 E, 14 S) for Leg 1, and between the Warruwi & Berrimah weather stations in Northern Territory for Leg 2.

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.

Leg 1 contains 56 files totalling 9.3 GB of raw data, covering approximately 483 nautical miles and
Leg 2 contains 279 files totalling 129 GB of raw data, covering approximately 1,448 nautical miles.

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 for Leg 1, but were applied to the processed data for Leg 2.

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.
