SV3/Tiny deployment to transit to Station M, test comm’s with Benthic Rover. Eco-Puck returned data over fetch. No obvious problems with the pump. The OA payload (Payload 3) shut off a few days into deployment and could not be restarted. MET data also stopped coming through around the same time. CW: "I sent my troubleshooting summary to LR and they suspected that we had a failure of one of the power boards inside the CCU box. A new board was purchased and we installed it this morning. Preliminary testing of the light and S3 payload port was successful and looks promising, but I will need to do more thorough testing in the next couple of weeks."
