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...
Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
Oceanographer and executive director of Oceana Europe , Xavier Pastor, led the Baltic Sea expedition. The crew covered more than 7,000 nautical miles and completed more than 130 dives to collect...
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...
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...
Dr. Martha Nizinski holds a specimen of a fan sponge ( Phakellia sp. ) collected at a deep-sea coral study site off the coast of South Carolina. Deep-sea corals and sponges provide structure for a...
Alvin, a human occupied vehicle (HOV), returns to the ship after a deep ocean dive to a seamount .
Scientists talk about the experience of exploring the ocean in this excerpt from the Deep Ocean Explorers video. More about deep ocean exploration can be found in our Deep Ocean Exploration featured...
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...
Studies along the Northwest Atlantic Ocean shelf break- the transition from continental shelf to slope- by researchers from Woods Hole Oceanographic Institution and Rutgers University are revealing...
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...
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...
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...
Picture this: clear, warm water bathing spectacular coral reefs , clouds of fish, circling sharks, and 17 scientists intent on studying the pristine tropical marine ecosystems of the Southern Line...
White abalones are slow-moving, algae-eating mollusks. Rapid overharvesting since the 1970s has resulted in white abalones becoming the first marine invertebrate listed as endangered on the...
Using a drill, a team removes a chunk from the thick Arctic ice. Small samples are taken from where the ice meets liquid seawater. The ice is then melted for analysis.
