This weekend the NOAA Ship Okeanos Explorer visited Shostakovich Seamount, and began its “Water Column Wonderland” week. Check out some of the unique creatures that live beneath the sea with imagery captured by remotely operated vehicle (ROV) Deep Discoverer! Continue reading Weekend Discoveries
From August 18, 2017, to September 3, 2017, the E/V Nautilus will be exploring the Olympic Coast National Marine Sanctuary (NMS), located along the Olympic Peninsula of Washington state. The sanctuary encompasses 3,189 square miles (8,260 km2), an area equivalent to the states of Delaware and Rhode Island combined. It extends 25 to 50 miles (40 to 80 km) from the shore, including most of the continental shelf, as well as three important submarine canyons: the Nitinat Canyon, the Quinault Canyon and the Juan de Fuca Canyon. The main objectives of this expedition are to explore and characterize seafloor resources and features associated with these submarine canyons. Quinault and Quileute Canyons have never been explored by remotely operated vehicle (ROV) or autonomous underwater vehicle ( AUV).
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).
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).

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.

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
On December 7th, 2016, the NOAA Ship Okeanos Explorer dove on two Japanese mini-subs that sank 75 years earlier, during the attack on Pearl Harbor. The USS Ward fired the first shot of the Pacific War, sinking this submarine 90 minutes before the air raid on Pearl Harbor. This attack marked the introduction of the United States into World War 2. Highlights from the dives on these submarines can be viewed below:
More photos and illustrations of the mini-subs and the USS Ward are available on the National Marine Sanctuaries website.

The NOAA Ship Okeanos Explorer‘s 2017 field season will kick off January 18, 2017, with a mapping expedition from Honolulu, Hawaii, to Pago Pago, American Samoa. This field season marks the third year of CAPSTONE, the Campaign to Address Pacific Monument Science, Technology, and Ocean Needs. The goal of which project is to collect data necessary to support science-based decision making for marine protected areas (MPAs) in the central and western Pacific.
