NOAA’s New Millennium Observatory (NeMO) was set up to study geologic, chemical, and biologic interactions along the mid-ocean ridge system. Learn more about NeMO and watch a video about underwater...
Researchers can study ocean acidification in the lab by rearing organisms in seawater with variable pH and measuring if they grow, eat, breathe, reproduce, or develop differently. It's common, for...
My father once told me that the world is divided into two kinds of people: those who believe that the world is divided into two kinds of people and those who don’t. Wherever you come down on this...
Did you know that over 17,000 species thrive in the deep sea where no light penetrates the ocean waves? Or that an old restaurant menu can teach us about the history of fish populations? Or that...
Nine years ago I was invited by a colleague to join a research team investigating deep-sea coral habitats . I was asked to examine the invertebrates associated with these ecosystems. After my first...
Peter Auster and colleagues direct a Remotely Operated Vehicle (ROV) dive on the New England Seamounts. Three teams composed of three scientists and four ROV engineers take two 4-hour watches every...
I’m a high school student interested in pursuing marine science. I have loved the ocean since I was 3 feet tall and only getting my feet wet at the beach. I’m a senior in high school, and over the...
Diving can be a wild ride that evokes more than a little trepidation, especially in the Pacific Ocean's famously big, cold waves. Waves that are otherwise fun for my weekend surfing can turn a...
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...
Marine biologist Mette Kaufman measures the temperature of a recently-drilled ice core . Variations in temperature at different points of the ice core provide information about the living conditions...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
Dr. Clyde Roper prepares to dive thousands of feet to a giant squid habitat off the coast of New Zealand in a one-person submersible. More about the giant squid can be found in our Giant Squid...
For more than two centuries, Boston Harbor has been a dumping ground. In 1773, colonists famously dumped shiploads of tea to protest taxes. But in recent decades, the harbor has received less tea and...
Mark Dodd, a wildlife biologist from Georgia's Department of Natural Resources, surveying oiled sargassum seaweed in the Gulf of Mexico after the Deepwater Horizon oil spill in 2010. Learn more about...
NOAA Teacher at Sea Ruth Meadows sorts specimens aboard the NOAA Ship Henry B. Bigelow as part of the Mid-Atlantic Ridge Ecosystem (MAR-ECO) project.
Follow a journey with satellite tags placed on bull sharks and tarpon. Both of these large predatory fish are found in coastal in-shore ecosystems and the two species have similar diets. If given the...
Researchers in Moorea use a variety of tools to collect organisms. Some are simple, everyday items like buckets and brushes, and some are…a little stranger. Here, two researchers use a “yabbie pump”...
At Carrie Bow Cay in Belize , Dr. Candy Feller explains her research on the effect of excess nutrients on mangrove swamps. Feller runs the Animal-Plant Interaction Lab at the Smithsonian...
