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...
Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
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...
Dr. Peter Auster gets ready for a dive to study the ecology of fish predators at Gray’s Reef National Marine Sanctuary off the coast of Georgia.
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...
An estimated 1.8 billion people will suffer from water scarcity by 2025. Looking for sources of water is becoming important and with oceans containing around 97% of Earth’s water, it would be nice if...
EPA divers from Atlanta place this instrument in Charleston Harbor in order to monitor currents and better predict sand movement for a harbor deepening project.
Save Our Seas scientist Alison Kock tags a Great White Shark ( Carcharodon carcharias ) to gather data about their movements off the coast of South Africa. More about the great white shark can be...
The mauve stinger’s ( Pelagia noctiluca ) name in German means “night light,” referring to the jelly’s reddish coloring and its bioluminescence, the display of light by a living creature. Unlike a...
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...
At Carrie Bow Cay in Belize , Dr. Candy Feller explains her research on the effect of excess nutrients on mangrove swamps. Feller runs the Animal-Plant Interaction Lab at the Smithsonian...
With 1,400 named species of ribbon worms inhabiting every ecosystem on earth, seeking one out should be an easy proposition. But I quickly learned that it can be quite daunting when you’re looking...
Arctic scientists study a range of marine animals – from large species like polar bears to the microscopic, like phytoplankton. The amount of phytoplankton at different depths can tell us about the...
Back at the lab, researchers sort the fish specimens they gathered in the field.
Dr. Amy Baco-Taylor observed corals like these on her first submarine dive to a deep-sea coral bed off the coast of Hawaii. They include primnoids, zoanthids, and Gerardia . The high density and...
The Chikyu allows scientists to gather and study data about seafloor sediments as soon as they are collected. After a powerful 9.0 earthquake triggered a devestating tsunami in Japan in March 2011 ,...
