Dr. Karen L. McKee collects a peat core in a mangrove forest in Belize. It will help her reconstruct how mangroves have changed over the past 8,000 years. Dr. McKee’s research has shown that when...
The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical...
Researchers use Autonomous Reef Monitoring Structures (ARMS) like this one to study the diversity of coral reef organisms. They leave the structures underwater for about a year. Then they retrieve...
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...
On May 31, 2009, this one-of-a-kind hybrid robotic vehicle reached the deepest part of the ocean—the Marianas Trench, located in the western Pacific Ocean, 10,902 meters (6.8 miles) below the surface...
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...
Dr. Robert Ballard poses with an unmanned submersible, like the one he used when locating and exploring the wreck of the RMS Titanic. A veteran explorer, former U.S. Navy Commander, and professor of...
Chilean and Smithsonian paleontologists study several fossil whale skeletons at Cerro Ballena, next to the Pan-American Highway in Atacama Region, Chile, in 2011. The fossils were discovered when the...
The pre-industrial American landscape was once rightly described as a place where “the deer and the antelope roam.” On land, we take it for granted that the plant-eating deer and antelope far...
The ocean is so big that it can be easy to forget the microscopic beauty of the organisms that live within. Some of this beauty is documented by the Nikon Small World photomicrography competition ,...
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...
Dr. Amy Baco-Taylor observed corals like these on her first submarine dive to a deep-sea coral bed off the coast of Hawaii. They include primnoids, zoanthids, and Gerardia . The high density and...
Ice divers Katrin Iken (left) and Elizabeth Siddon are about to descend through a hole in the Arctic ice and into the frigid world below.
Dr. Amy Baco-Taylor dives to deep-sea environments to study corals and the invertebrates that live in them. Learn how she became interested in deep-sea corals , and explore more in the multimedia...
Expedition data went to the Arctic Ocean Diversity database of the Census of Marine Life to establish a baseline that will help to document change in the poorly known Arctic Ocean. Scientist Kevin...
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”...
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...
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...
