Tuning into the Musician Seamounts

During their 2015 Hohonu Moana expedition, the NOAA Ship Okeanos Explorer discovered and mapped an unnamed seamount in the Central Pacific Ocean Basin (shown in the image above). The ship and scientists are now returning to this region, “Musician Seamounts”, to conduct additional mapping and remotely operated vehicle (ROV) operations over two consecutive cruises. These efforts will be focused north of the Hawaiian Islands, close to the Papahānaumokuākea Marine National Monument (PMNM).

From August 8th through August 31st, 2017, the Okeanos Explorer will map the area using multibeam sonar technologies aboard the ship.   Operations will start and end in Honolulu, HI. The additional mapping data will assist in better understanding the geologic history of the seafloor in the remote Pacific Ocean.

During the second cruise, from September 6th through September 30th, 2017, the ROVs Deep Discoverer and Seirios will explore the waters around the Musician Seamounts. By observing the marine habitat and organisms in this area, scientists hope to learn more about life in the Pacific Ocean Basin and the composition of the ocean ecosystem of this region.

The currents and upwelling of nutrients occurring in seamounts creates optimal habitat for high-density coral communities, as shown here in this image taken during a 2015 Okeanos Explorer dive on the Swordfish Seamount, in the Pacific Ocean.

Living Fossil: Tiny mollusc makes big impression on marine biology world

A February 2017 dive by the NOAA Ship Okeanos Explorer yielded an exciting discovery. Scientists spotted a live monoplacophoran, a rarely observed type of mollusc that is thought to be the closest living relative of the ancestors of modern day bivalves (e.g. clams and mussels) and gastropods (e.g. snails).

A Rare Opportunity: Observing the life cycle of a young volcano

The NOAA Ship Okeanos Explorer has kicked off its 2017 field season so far with amazing dives in the waters off American Samoa, a US territory in the southern Pacific Ocean. In February 2017, the expedition team explored the Vailulu’u Seamount, an underwater volcano located east of the  Samoan Island of Ta’u. This offered scientists a rare and exciting opportunity to observe the geological and ecological characteristics of an active underwater volcano.
