NOAA Ship Okeanos Explorer Gulf of Mexico 2017 Expedition

Welcome to the NOAA Ship Okeanos Explorer Gulf of Mexico 2017 expedition! The team will be exploring the Gulf of Mexico from November 29 – December 21, 2017, using multibeam sonar and the remotely operated vehicle (ROV), Deep Discoverer, to explore the  seafloor. The 23-day expedition will focus on acquiring data on priority exploration areas identified by ocean management and scientific communities.  Tune in to the live streams and explore with us!

Titanic Returns for its 20th Anniversary

In honor of its 20th anniversary, the 1997 film, Titanic, is being brought back to the big screen, for one week only, in select AMC Theatres.

Most of the film is based on real events. In 1985, the eventual founder of URI’s Inner Space Center, Graduate School of Oceanography professor, Dr. Robert Ballard, discovered the wreck in its resting place at the bottom of the North Atlantic Ocean.

Creature Comparison: Corals and Sponges

Despite being frequently encountered by scientists aboard the NOAA Ship Okeanos Explorer, E/V Nautilus, and other exploration vessels, much is left to learn about corals and sponges. Both are sessile (non-moving) organisms, serve as vital resources for other marine life, and can indicate the health of oceanic ecosystems. Learn more about these fascinating animals below!

Corals

Corals exhibit some plant-like characteristics, but are actually animal relatives of jellyfish and anemones. They are all within the phylum Cnidaria. All corals are classified as either “hard corals” or “soft corals”. Hard corals have a limestone skeleton, and make up the foundation of a coral reef. They can take a rounded, branching, or flat appearance. Soft corals bind together on a softer structure, and can take the shapes of whips, spirals, and trees. Hard corals can grow as much as ten centimeters per year, the same rate of growth as human hair, but most only grow up to three centimeters each year.  Soft corals grow at a rate of two to four centimeters per year. When a coral reef is damaged by a storm, pollution, or by other factors, it may take a significant amount of time before it is able to recover and grow to its former size.

A variety of soft octocorals were found on the East “Wetmore” Seamount near Hawaii at around 2,065 meters deep (6,775 feet). (Image courtesy of the NOAA Office of Ocean Exploration and Research, 2017 Laulima O Ka Moana.)

Weekend Discoveries

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

Ocean Exploration, “Olympic-Style”

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).

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).

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). Continue reading Living Fossil: Tiny mollusc makes big impression on marine biology world

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.

Discovering the Deep: Exploring Remote Pacific MPAs

On March 25th, the NOAA Ship Okeanos Explorer wrapped up an exciting cruise to explore the depths of remote Pacific Marine Protected Areas (MPAs). As scientists collected data and made discoveries over the course of the expedition’s 19 dives, the remotely operated vehicles collected amazing images of life in the deep ocean. Continue reading Discovering the Deep: Exploring Remote Pacific MPAs

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
