Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2020_V10, titled MNF Trials, Storm Bay Modelling and Information System Data Collection, and Bathymetric and Benthic Habitat mapping of the Huon AMP. The voyage took place from 11-22 November 2021 departing from Hobart (TAS) and returning to Hobart (TAS).

The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter through the shelf-break region and seamount clusters within Huon AMP.

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 and *.wcd format for watercolumn backscatter at CSIRO. There are:

-148 files totalling 8.7GB of raw *.all files in this dataset.
-106 files totalling 9.6GB of raw *.wcd files 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 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.
