Full description

This record describes multibeam echosounder data collected on RV Investigator voyage IN2026_V01,titled "Cook Ice Ecosystems and Sediments (COOKIES)." The voyage took place between January 02, 2026 and February 25, 2026 (AEST), departing from Hobart and returning to Hobart.

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 1226 files totalling 122 GB of raw data and 1226 files totalling 193 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.

Maintenance and Update Frequency: asNeeded
Statement: Original field data. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position and edited using CARIS version 12.1.1
