Watch as Dr. Dallas Alston and a team of researchers study the effects of aquaculture at a fish farm near Puerto Rico. With careful planning and good daily practices, aquaculture can be part of a...
J. Murray Roberts is a scientist who studies and maps an area of the cold-water coral called Lophelia in the North Atlantic, where the bases of some coral mounds are 2.6 million years old. Explore...
In the wet lab aboard the R/V Seward Johnson , Dr. Martha Nizinski examines a sample of the deep-sea coral Lophelia pertusa , collected 600-m (1,969-ft) deep off the coast of the southeastern United...
"Inside the Open Ocean: Blue Water Diving" produced by Woods Hole Oceanographic Institution (WHOI) , describes a specialized diving technique that lets biologists study the ocean's most fragile...
Fargo, the dog pictured here, is not just having a relaxing day at sea. He is helping researchers at the New England Aquarium in Boston detect scat (or poop) from North Atlantic right whales . The...
Back at the lab, researchers sort the fish specimens they gathered in the field.
Dr. Clyde Roper, Smithsonian zoologist and squid expert, tries to measure up to a giant squid specimen (Architeuthis) from New Zealand. The squid wins. More about the giant squid can be found in our...
A scientist, Chris Reddy from Woods Hole Oceanographic Institution, collects oil-laden "sand patties" on a Louisiana beach two years after the oil spill. Watch a video of Chris Reddy talking about...
Scientists from the Integrated Ocean Drilling Program (IODP) collect sediments drilled from Earth’s crust. This marine research program supported by 24 countries is increasing our understanding of...

If you think only men can helm research vessels to get their hands dirty and study ocean currents, you're wrong. This short film follows the mostly-female scientists of the R/V Knorr research ship on...
The Woods Hole Oceanographic Institution's "Line W" program is conducting research to better understand how the oceans and the atmosphere work together to cause, and are affected by, climate...
Two events made me passionate about deep-sea corals . One was my first submarine dive in a deep-sea coral bed off the Hawaiian island of Oahu. There was an incredibly lush community of corals and...
