Adding a hook to the Trident

​As I mentioned in previous posts, we want to use the Trident to recover our hydrophone and camera array from the seafloor. While planning for the next deployment, I took some time to perform some tests and added a pole at the front of the Trident with a carabiner. After few iterations, I found a reasonable design that does not affect too much the maneuverability of the Trident and is easy to put together (and repair in the field). Once hooked to the mooring, the carabiner detaches itself from the pole and is closed using a simple quick release mechanism. I tested it in shallow water (5m) off a dock nearby and it worked pretty well. The real test will be to use it in deeper water, but things look promising so far.

Our instruments are working again and we are planning to deploy the fish array in the next few days, as soon as the weather calms down. Stay tuned...
