Is seaweed the future of fuel?

Engineering & Technology Magazine

“Macroalgae needs to scale up to the point where it’s economically feasible for biofuel, and to do this we are going to have thousands of hectares of farms,” says Erin Fischell, an assistant scientist at WHOI.

A New Ship’s Mission: Let the Deep Sea Be Seen

New York Times

Mr. Dalio was thinking of buying the Alucia when a team of WHOI experts used the vessel and an undersea robot to find the shattered remains of Air France Flight 447, which in 2009 had vanished over the South Atlantic with 228 passengers. Other search teams had failed, and Mr. Dalio saw the 2011 success as an indication of the field’s exploratory promise.

Exploring Deepwater Ecosystems with eDNA

Between September 23-27, 2019, a team of ocean scientists and engineers from WHOI and Lehigh University used NOAA research vessel Manta and the newly developed autonomous underwater vehicle (AUV) Mesobot to collect environmental DNA (eDNA) in order to explore the biodiversity of deepwater ecosystems near Flower Garden Banks National Marine Sanctuary in the Northwestern Gulf of Mexico.

Welcome home, Alvin!

Alvin is the world’s longest-operating deep-sea submersible. It was launched in 1964 and has made more than 4,700 dives, along the way participating in some of the most iconic discoveries in the deep ocean. Throughout 2011, 2012, and into 2013, Alvin received a comprehensive overhaul and upgrade funded by the National Science Foundation that greatly expanded its capabilities and will eventually put almost the entire ocean floor within its reach.

Opening our eyes to the deep: Molly Curran

Molly Curran is a mechanical engineer in WHOI’s Deep Submergence Laboratory. She works on the design and operation of deep-sea robotic systems, including remotely operated vehicles, autonomous vehicles, and deep-sea samplers. She was the institution’s first pilot for Mesobot, WHOI’s latest autonomous robot designed to study the midwater realm known as the ocean twilight zone.

ROV Jason captures underwater video during earthquake

In January and February 2020, scientists on R/V Atlantis explored hydrothermal vents on the Cayman Rise. They used the remotely operated vehicle Jason to get an up-close view of the vents and life around them. The vents lie on a seismically active part of the seafloor known as a mid-ocean ridge. Deep-sea shrimp swarm the vents, feeding on microbes that live on chemicals flowing from the vents. While they were there, a magnitude 4.7 earthquake struck just 100 miles away. Scientists will now be able to study how seismic activity affects hydrothermal vents and the life around them.

Nereid Under Ice explores Aurora hydrothermal vent field

nereid under ice vehicle

The newly upgraded Nereid Under Ice, a hybrid remotely operated vehicle, is deployed from the Norwegian Icebreaker KronPrins Haakon to conduct its first deep ocean dives to 4,000 meters (over 13,000 feet) along the Gakkel Ridge in the Arctic Ocean.
