Video feed from a robotic submersible used to explore the impacts of low oxygen along the Oregon coast. Depicted are scenes recorded before the on set of anoxia, or zero oxygen conditions of shallow rocky reefs showing diverse populations of rockfishes and large bottom-dwelling marine life. The onset of anoxia during the summer of 2006 resluted in the disapperarnce of all fishes and die-offs of most large bottom-dwelling marine animals including Dungeness crabs, marine worms, sea cucumbers and sea stars.
