Full description

This record describes multibeam echosounder data collected on the RV Investigator voyage IN2016_V03, 'Monitoring Ocean Change and Variability along 170° W from the ice edge to the equator', which departed Hobart on the 26 April 2016 and returned to Lautoka, Fiji on the 30 June 2016. There was a port call at Wellington, New Zealand, 26 - 27 May for some science personnel change; this resulted in two "legs" of the voyage therefore Leg 1 is 26 April - 26 May 2016, and Leg 2 27 May - 30 June 2016.

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

The EM710 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 at CSIRO. There are 46 files totalling 5.51 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 has had outliers removed. Processed line data is available in *.gsf and ascii format and processed bathymetry 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.
