My Trip to the Bottom of the Sea

What’s it like to travel to the bottom of the sea? Lamont graduate student Bridgit Boulahanis describes the bioluminescence and colorful sea life as she explores a seamount by mini submarine in the Pacific Ocean.

Exploring Obama’s Seafloor Canyons by Mini Submarine

Only a few people have ever explored deep inside the seafloor canyons that President Obama just designated a national marine monument. Bill Ryan is one of them. In this podcast he describes what his team saw and learned.

Shipboard Science: It’s All About Collaboration This Week

Early-career scientists aboard the UNOLS training cruise are getting to try new techniques and technologies, and collaborations are springing up everywhere.

The Magic of Exploring Under the Sea

It’s midnight on the ship, and the labs are filled with scientists busy examining samples. Two of them just got back from a trip to the seafloor, and the excitement is palpable.

Life Aboard a Research Cruise: 24-Hour Workdays, Amazing Discoveries

When scientists say “research cruise,” they aren’t talking about sunny afternoons of shuffleboard and margaritas on deck. Life aboard a research vessel means tight spaces, few amenities, and long workdays.

The AUV Sentry discovered an area of seafloor where methane is bubbling up, similar to the earlier photo. The data will be used to plan the team's next dive with scientists inside a submersible. Photo: NOAA

Roving the Abyss: It Takes a Team

Bridgit’s first mission with the autonomous underwater vehicle (AUV) Sentry was a rousing success, including locating a patch of seafloor where methane is bubbling up.

When Doing Science at Sea, Prepare to Adapt

Bridgit’s research training cruise started with a fundamental lesson of ocean science: Science at sea requires constant adaptation. Morning fog meant rewriting dive plans and reconsidering priorities.

Going Deep for Science

Bridgit Boulahanis, a marine geophysics graduate student at Lamont-Doherty Earth Observatory, prepares to head out on her first research cruise exploring the seafloor with underwater vehicles.

Climate Change Leaves Its Mark on the Sea Floor? Maybe Not

A new study in Science questions the provocative idea that climate change may shape the texture of the sea floor. A Snickers bar helps explain what’s really going on.

The Lamont Seamounts are an example of the view from the seafloor synthesized by a team of oceanographers at Lamont-Doherty Earth Observatory. The seamounts are due west of El Salvador, at about 9.55 degrees N, 104 degrees W.

Time and Technology and the Really Down Deep

Two years before Google Earth was launched, Bill Ryan and Suzanne Carbotte, oceanographers at the Lamont-Doherty Earth Observatory, began a project to transform the way we look at the ocean. They started collecting reams of data that had been gathered by scientists sailing on research vessels all over the world since the 1980s, one ship transect at a time.
