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...
These watercolor sketches of Trapezia crabs were drawn by Frederick Bayer, a former Smithsonian coral biologist, in 1947. Trapezia crabs live on and within corals, feeding on their tissue and mucus,...
Scientists from the Integrated Ocean Drilling Program (IODP) collect sediments drilled from Earth’s crust. This marine research program supported by 24 countries is increasing our understanding of...
The long silver tool shown here is a piece of traditional Australian fishing gear called a “yabbie pump.” Researchers use the device to collect burrowing shrimp and other fast-moving animals from the...
Photographer David Liittschwager took a 12-inch metal frame to Moorea, French Polynesia, and four other disparate environments to see how much life he could find in one cubic foot. Read more about...
Ocean Sampling Day 2014 will be the largest ocean sampling effort ever orchestrated on a single day. Over 170 sites globally will participate, with every participating site represented on the map...
Diving to survey, sample, and manage marine life takes a great deal of skill and knowledge. This diver is sampling the seafloor, also known as the benthic zone. This kind of sampling is important for...
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...
Cooks Bay in Moorea is one of the places that researchers are scouring in their quest to collect one of every life form big enough to pick up with tweezers. In the background is Mt. Rotui—the...
This brightly colored squat lobster collected in Moorea is a common find among the coral heads. Although called lobsters, this group of crustaceans is more closely related to hermit crabs than to...
