Deep-sea Corals

Deep-sea Corals

Not all corals are found on island coasts in shallow seas. In fact, over half of all known coral species are found in deep, dark waters where temperatures range from 4-12° C. For this reason, we call these corals the “cold-water” or “deep-sea” corals. They are found all over the world

Deep-sea Canyons

Deep-sea Canyons

Submarine canyons are steep-sided valleys cut into the sea floor of the continental slope, sometimes extending well onto the continental shelf. These canyons vary in size, shape, and morphological complexity; some were scoured by the flow of rivers during past low sea level periods, but most formed via other erosional processes, such as mud-slides, debris flows, and turbidity currents.

Cold Seeps

Cold Seeps

Cold seeps are locations where hydrocarbon-rich fluid seeps up from below the sea floor, often as methane or hydrogen sulfide. Cold seeps have been found to support significant chemosynthetic communities.
