Recently I became involved with a series of expeditions to lost colonial mines and caves in the northeast. We’re currently using my OpenROV to explore the flooded section in search of artifacts. The water in the mines is low in oxygen, so there is not much bacteria in the water. Due to this we hope to find organic artifact that usually would have decayed by now. In the near future we hope to up our game with an upgrade to the new Trident ROV.
Here you can see the teaser for a documentary of our explorations of mines & caves where we deploy the OpenROV.
