RV Investigator Voyage IN2021_E01 EK60/EK80 Echosounder
This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2021_E01 (Trials and Calibration) which departed Hobart on the 10th November 2021 and returned to Hobart on the 14th November 2021.
The purpose of this voyage was to undertake annual equipment calibrations and commissioning, sea trials and personnel training. The Simrad EK80 wide band transceivers (WBT) 18, 38, 70, 120, 200 and 333 kHz and the EK60 split-beam GPT 18, 70, 120, 200 and 333 kHz were calibrated at the start of this voyage at anchor in the Derwent Estuary on the 10th November 2021. The EK80 WBTs were calibrated using default settings for both CW and FM modes. The EK80 system was then used to acquire acoustic backscatter data to a range of 1500 m for the remainder of the voyage offshore to the southeast of Tasman Peninsula.
All frequencies were logged sporadically for the extent of the voyage. The frequencies were set to passive for periods during the voyage when conducting other system calibrations. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 289 files totalling 25.7 GB of raw data in this dataset. No processing has been conducted on this data.
Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request.
