The purpose of this voyage was to undertake post port-period equipment calibrations and commissioning, sea trials and personnel training.The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter in Storm Bay and offshore to the southeast of Tasman Peninsula. A patch test calibration was performed to determine the angular offsets of the system on July 30, 2020.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 and during this voyage was acquired with a frequency range setting of 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 122 files totalling 12.4 GB of raw bathymetry (.all) data and 118 files totalling 89.3 GB of raw watercolum (.wcd) in this dataset.Sound velocity profiles were applied to this data during data acquisition.

Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2020_E01 (Trials and Calibration) which departed Hobart on the 29th July 2020 and returned to Hobart on the 6th August 2020. The purpose of this voyage was to undertake post port-period equipment calibrations and commissioning, sea trials and personnel training.

The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter in Storm Bay and offshore to the southeast of Tasman Peninsula. A patch test calibration was performed to determine the angular offsets of the system on July 30, 2020.

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 and during this voyage was acquired with a frequency range setting of 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 122 files totalling 12.4 GB of raw bathymetry (.all) data and 118 files totalling 89.3 GB of raw watercolum (.wcd) 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 all of the the processed data. GPS tide was applied to files 0083, 0085, 0087, 0090, 0092, 0096, 0098, 0100 & 0103 (bathymetry reference surface lines) and files 0031, 0033, 0035, 0037, 0040, 0042, 0044 (patch test lines). Processed data has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry in geotiff format.
