Following a 1902 collision off the Massachusetts coast, the coal schooners Frank A. Palmer and the Louise B. Crary now exist as one intertwined wreck, captured by here side-scan sonar in Stellwagen Bank National Marine Sanctuary.Read More
In May 2021, members of WHOI’s Ocean Twilight Zone project braved the rough seas of the Northeast Atlantic aboard the Spanish research vessel Sarmiento de Gamboa. Their mission: locate the spring phytoplankton bloom and measure how carbon moves through the mysterious mid-ocean “twilight zone.”
The Sarmiento joined two other research vessels funded by NASA’s EXPORTS program to intensively study the area. This remarkable and rare coordination of 150 scientists from several organizations, and crew on three different ships, was years in the making.
Watch as the WHOI research team, led by Ken Buesseler and Heidi Sosik, deploys innovative new imaging technologies and hauls up hundreds of fascinating specimens from the deep sea. Along the way, you’ll gain an endless appreciation for the vast, weird, and wonderful ocean twilight zone – without getting wet.Read More
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.Read More

Phytoplankton use sunlight and carbon dioxide to grow, forming the base of the ocean food web. Phytoplankton are eaten by zooplankton, which are eaten by other animals. Dead zooplankton and other particles become marine snow drifting in the ocean, but how much marine snow sinks below the sun-lit ocean surface? Scientists are developing a new device
that will follow marine snow into the ocean’s twilight zone.
The MINION is a small (2 Liters) inexpensive instrument. It is equipped with… cameras, seawater sensors, acoustic recorder, ballast weight. Once deployed, MINION will sink to the twilight zone and drift with currents.
Cameras on the side record the rate and quantity of particles falling through the ocean. Falling particles also accumulate on a clear glass panel. A camera on top will record the particle type and accumulation rate.
Similar images have revealed the twilight zone is a perpetual snowstorm, of organic debris. Particles such as this fecal pellet from a jellyfish-like salp are extremely carbon-rich. Pellets like this will sink quickly to deeper waters, or even become buried in the seafloor. Any marine snow that reaches the deep ocean means less carbon in the atmosphere.
The MINION is designed to listen for underwater sound sources. This will determine their location as they drift.
After a MINION has finished its mission, it will release weight and float to the surface. At the surface, it sends a homing signal so it can be recovered. The next generation of MINION will send compressed data-sets via satellite. Allowing them to be deployed by the dozens. Data from MINIONS will help scientists learn more about the ocean’s role in Earth’s climate system.Read More
