After landing on rippled sediment to start Dive 12 of the 2021 North Atlantic Stepping Stones expedition, the remotely operated vehicles moved towards a steep slope, along the way encountering a large boulder field that looked to be the result of mass wasting of igneous rocks from above. In many places, debris flow of rock cobbles and sediment chutes were evident. In this area of bouldered terrain, we observed black corals, as well as sparse, mostly dead bamboo corals.
