Deep Sea Sponges and Invertebrates on Vogt Seamount
While exploring Vogt Seamount, our Corps of Exploration encountered multiple deep-sea sponges and their associated species. Dead sponge stalks provide habitat for associates, such as worms and Venus flytrap anemones (Actinoscyphia aurelia), which use their height to catch prey floating by in the water column. Previous dives here have documented high abundance and diversity of deep-sea corals and sponges, and this follow-up did not disappoint. Check out a bunch of unique creatures, hydroids, nudibranchs, and even carnivorous sponges!
The Mattingan: Mariana Arc Volcanic Exploration (NA171) expedition is exploring deep-sea areas identified by the local management and science community, including sites with signatures of active volcanism, abyssal plain habitats, and areas in and around the Monument where new data can support resource management priorities. This expedition is supported by NOAA Ocean Exploration, the Bureau of Ocean Energy Management, and the US Geological Survey via the Ocean Exploration Cooperative Institute.

Mattingan: Mariana Arc Volcanic Exploration
E/V Nautilus will begin the 2025 season exploring the ocean of the Mariana Islands- one of the most tectonically and volcanically dynamic locations on the planet. This area is home to one of the most active arc volcanic systems on Earth with more than 60 submarine volcanoes, and a back-arc spreading center where new seafloor is created.
