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 use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
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...
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...
In recent years, I have taken to watching flying fish along the Maine coast. Not the usual flying fish that skim over tropical seas, but fish dangling from the beaks of flying puffins. Puffins are...
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...
In 2009, Ruth Meadows, a science teacher from Opelika Middle School in Opelika, AL was part of a team of international scientists that may have found a new species! Led by Mike Vecchione of the NOAA’...
Ice divers use a quadrat to study the density of creatures living on the underside of Arctic ice floes. A quadrat is a standardized square used to take sample measurements that allow researchers to...
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...
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...
New England Aquarium researchers Dr. Moira Brown and Yan Guilbault conducting aerial surveys for North Atlantic right whales over the Roseway Basin, Canada. More about right whales can be found in...
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...
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...
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...
Reef sharks rarely get any love. These sharks, comprising several species, loiter around coral reefs, snacking on small fish, squids and crustaceans. And while their size is nothing to smirk at—5-10...
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...
