December 14, 2021 — Incredibly rich and diverse deep coral and sponge communities are thriving in Papahānaumokuākea Marine National Monument, researchers concluded after a 20-day deep-sea research expedition.
The team of NOAA, Ocean Exploration Trust, researchers and partners returned from the voyage on Dec. 6. What they encountered during the course of their work blew them away.
“The sheer size and density of some of these ancient sponges boggles my mind. This expedition shows me what a treasure we have in the monument,” said Dr. Christopher Kelley, retired University of Hawai’i researcher and one of the leaders of the expedition. “In my 21 years exploring the deep-sea environment of Hawai’i, and well over 100 submersible and ROV dives in the archipelago, the communities on these seamounts have to rank as some of the best I have seen.”
The research team reported their findings in a press release issued Monday, Dec. 13.
