Full description

This record describes ME 70 scientific multibeam fisheries echosounder data collected on the Marine National Facility (MNF) RV Investigator voyage IN2025_V04, titled "Untangling the causes of change over 25 years in the southeast marine ecosystem - Voyage IV." The voyage took place between May 27, 2025 and June 28, 2025 (AEST), departing from Hobart and returning to Hobart.

The Simrad ME70 scientific multibeam echosounder acquired acoustic backscatter data through the water column up to 500 m (maximum). The echosounder's frequency range is from 70 kHz to 120 kHz. The ME70 logged sporadically only for specific trawling operations for the extent of the voyage.

Data are stored in Simrad *.all raw format at CSIRO. There are 519 files totalling 60.2 GB of raw data in this dataset.

No processing has been conducted on this data.

Additional information regarding this dataset, including the settings used, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
