Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
A drawing of Phoenix from the Right Whale Catalog documents her callosity pattern and other identifying marks. More about whales can be found in our Tale of a whale featured story .
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...
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...
How many animals swim in the sea? It's not easy to count them all. To get a feel for the ocean's diversity, scientists, such as those involved in the Census of Marine Life , sail out on research...
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...
A student from the University of Cape Town in South Africa uses a field guide to help identify organisms during a shoreline survey at Cape Columbine.
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...
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...
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...
So far, researchers have developed DNA barcodes to accurately identify 4,600 of the more than 29,000 known fish species. Atlantic cod is an economically important fisheries species. However, it's...
Now that the Census of Marine Life is over, we’re checking in with some of the researchers to hear about their favorite expedition, what they learned, and how the Census and its findings continue to...
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,...
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...
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...
The rough patches of skin known as callosities occur in unique patterns on all North Atlantic right whales and help researchers identify and track individual whales. This whale is named Phoenix. More...
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...
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...
