If you are a bird watcher you have probably heard of the Christmas Bird Count. The first one occurred on Christmas Day in 1900 at a variety of locations throughout North America, and it has since...
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...
Dr. Candy Feller is framed by the roots of a mangrove tree on Panama’s Pacific coast. Mangrove trees grow particularly large in this area. More about mangroves can be found in our Mangroves featured...
Dr. Valerie Paul is studying chemical defenses that may protect coral reefs from many species of herbivores that live on coral reefs. In this picture she is examining tropical seaweeds on...
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...
Back at the lab, researchers sort the fish specimens they gathered in the field.
To learn more about the creatures living on the Arctic seafloor, scientists use a variety of tools including this box corer.
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 world beneath the Arctic ice is magical, but cold. Divers have to tolerate temperatures of 30 degrees Fahrenheit (about -2° Celsius.) To stay warm they wear thermal undergarments and use special...
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...
There can be catastrophic results when a large amount of oil is spilled into the ocean—as when the Deepwater Horizon rig exploded and spewed oil into the Gulf of Mexico in 2010. But did you know that...
Alvin, a human occupied vehicle (HOV), returns to the ship after a deep ocean dive to a seamount .
Doing scientific research on a ship isn't always easy. On top of having to live and sleep on a boat on the water, you have to fit all your scientific equipment onboard—and make sure it continues...
This is the world’s first unmanned, underwater robot—or “glider”—to cross an ocean basin, the pioneering Scarlet Knight . The robotic glider, also known as RU27, can dive to depths of 200 meters (660...
A number of questions have inspired marine ecologist Stuart Sandin to head to the coral reefs of the Line Islands . Sandin works at the Scripps Institution of Oceanography at the University of...
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...
Hermit crabs, like this one collected in Moorea, usually protect their soft, vulnerable abdomens from predators by reusing empty snail shells. They are picky home owners and they will trade shells...
