Instruments Mobilization & Setup – Day 1

Today we mobilized and set up the CSEM and multi-beam systems onboard the Huki Pono survey boat. We tested the two CSEM transmitters (Main unit: 150 Amp output current; Spare unit: 50 Amp output current) with a dummy-load, and they both operate as expected. The multi-beam head was adjusted to the ideal depth of transmission and tested successfully. After all, we had a pretty good first day, as team members worked together to prepare the boat for the survey. Thank guys for all of your hard work!
