Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2025_V03, titled "COAST‐k – Clean Ocean Air Sampling upwind of Tasmania ‐ kennaook" which departed Hobart on April 29 2025 and returned to Hobart on May 18 2025.

The EM124 provides a 1 degree by 1 degree angular resolution. The echosounder's nominal frequency is 12 kHz.

Data are stored in *.kmall raw format for bathymetry and backscatter and *.kmwcd format for watercolumn backscatter at CSIRO.

There are 220 files totalling 18.1 GB of raw data and 220 files totalling 36.4 GB of watercolumn data in this dataset.

Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.kmall format are corrected for motion and position.

GPS tide was computed using the EGM2008 model and applied to the processed data. Processed data has had outliers removed.

Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report.
