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.

The Scintillating Sea Life of Pao Pao Seamount

The NOAA Ship Okeanos Explorer had an amazing dive March 9, 2017 on Pao Pao Seamount, an underwater mountain in the Tokelau Seamount Chain in the South Pacific. Continue reading The Scintillating Sea Life of Pao Pao Seamount

To Boldly Go… Ahyi Seamount

About 12.5 miles off the coast of Farallon de Pajaros, within the Mariana Trench Marine National Monument, lies the Ahyi Seamount, an active underwater volcano. This site remained unexplored until June 22nd, 2016, when the NOAA Ship Okeanos Explorer launched its remotely operated vehicles (ROVs) to investigate the volcano.
