Corals, Seamounts & Canyons
The deep-sea landscape and its gardens — ancient cold-water corals, towering seamounts, submarine canyons and the oases of life they shelter.

- — Dive 06: Ellis Seamount: 2015 Hohonu Moana. Dive 06 of the third leg of the 2015 Hohonu Moana: Exploring Deep Waters off Hawaii expedition was the first dive ever conducted on Ellis Seamount, located in the Geologist Seamounts group. The objective of this dive was to survey a rift zone ridge coming off the northern end of the seamount for corals and sponges, to gather more information on whether high-density communities can be found on ridge topography. From beginning to end, the dive observed high densities of coral colonies.
- — Corals in Concert: 2017 Deep-Sea Symphony. Deep-sea coral and sponge communities are often hot spots of biodiversity, providing important habitat for life within deep ocean waters. As the ocean knows no boundaries, NOAA has a responsibility to study these communities both inside and outside of U.S. waters. The area explored in the Musicians Seamounts during the Deep-Sea Symphony expedition hosted some of the most-dense coral and sponge communities encountered throughout the entire CAPSTONE project in the Pacific.
