MiniROV and ROV Doc Ricketts
February 26, 2015
Today was another very successful day aboard the Western Flyer, with nearly six-hour dives with both the MiniROV and ROV Doc Ricketts. Working with both ROVs lets us cover a greater depth range than with one alone. As I mentioned in the February 22 post, ROV Doc Ricketts is capable of very deep dives (up to 4,000 meters), but is not easily maneuverable at depths shallower than 200 meters. The MiniROV, on the other hand, can easily work at the surface and down to 1,000 meters. The MiniROV is small and due to its electric power, it is very quiet compared to the Doc Ricketts, which uses hydraulic power. The Doc Ricketts is large and powerful, but loud, which can affect the animals we observe. Using each ROV for half of the day allows us to thoroughly survey the deep midwater.
Everyone on board the ship is involved in the daily operations during the expedition. We are very grateful for the crew and pilots, who make doing our research not only successful, but fun, too!
Just in case you were disappointed that I didn’t include any beautiful images of deep-sea animals…here you go. This gorgeous shot was taken with ROV Doc Ricketts’ high-definition video camera.
