RV Investigator Voyage IN2017_V03 EK60 Echosounder

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2017_V03, 'Sampling the abyss: latitudinal biodiversity patterns along the base of Australia’s eastern continental margin' which departed Bell Bay on the 15 May 2017 and returned to Brisbane on the 16 June 2017.

The Simrad EK60 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data when possible. All frequencies were logged mainly when transitting between sites as all ship acoustics were turned off when listening for beacon signals on most operations.
Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 45.5 GB of raw data in this dataset.

Amy Nau, will be processing this data.
