Deploying ARMS (Autonomous Reef Monitoring Structures) is tricky in the deep sea, where SCUBA divers can't place and secure them to the floor with their hands and a hammer. Researchers with DROP (...
This illustration shows how Scarlet Knight , the first unmanned, underwater robot or glider to cross an ocean basin, faced an entire fleet of fishing ships, equipped with nets, threatening the glider...
In the late 1990's, researchers at the Woods Hole Oceanographic Institution (WHOI) invented the D-Tag —a radio device that can be attached by suction cups to a whale's back. Using a tiny underwater...
In 2011, Oceana researchers spent two months surveying life and conditions in the Baltic Sea. The team covered more than 7,000 nautical miles and completed more than 130 dives. The data, samples,...
The spiral-tufted bryozoan ( Bugula neritina ) is being studied for a potential Alzheimer's disease and cancer drug—but it's not the bryozoan that makes the chemical. The chemical, found in the...

Great White Sharks are stealthy hunters and the secret is in their skin. Shark skin is covered by tiny flat V-shaped scales, called dermal denticles, that are more like teeth than fish scales. These...
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...
