The purpose of this voyage was to undertake post port-period 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 333 kHZ were calibrated at the start of this voyage at anchor in the Derwent Estuary on July 29, 2020. 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. The EK60 split-beam GPTs for 18, 70, 120 and 200kHz were calibrated at anchor in the Derwent Estuary at the end of the voyage on August 6th, 2020. 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.
