Throughout the course of the second leg of the Okeanos Explorer Northeast U.S. Canyons 2013 Expedition, scientists on the ship and on shore, along with the remotely operated vehicle (ROV) team and ship's crew, were joined by thousands of online viewers as we all explored canyons and intercanyons and Mytilus Seamount along the northeastern coast of the United States. This video captures highlights from the 15 dives that were conducted during Leg 2 of the expedition from the ROV Deep Discoverer and the Seirios camera platform.
