Northeast Pacific Seamounts

Seamounts—underwater mountains that rise from the sea floor—are internationally recognized as critical to protect for healthy oceans.

These highly-structured environments are ideal for coral and sponge growth, in turn providing nursery and foraging habitat important for fish populations and other marine life.

    From July 5-21, 2018, the Haida Nation, Fisheries and Oceans Canada, Oceana Canada, and Ocean Networks Canada embarked on an expedition to explore seamounts near the islands of Haida Gwaii in the northeast Pacific Ocean off the coast of British Columbia.

    The expedition team spent 16 days on board Ocean Exploration Trust’s state-of-the-art vessel, Nautilus, equipped with two remotely operated vehicles (ROVs) Hercules and Argus, and a multi-beam echosounder used for seafloor mapping.

    All known seamounts located in Canadian waters are found off the coast of British Columbia, near the islands of Haida Gwaii. This expedition surveyed three of them: SGaan Kinghlas-Bowie, Dellwood and Explorer.

    The ROVs installed long-term ocean monitoring instruments on Dellwood and collected scientific data and samples as well as established monitoring sites on all three seamounts. In addition, high-definition video was captured by the ROVs and streamed in real time online to share with the world.
