In 2009 Dr. Vecchione served as Chief Scientist on a six-week expedition to the Mid-Atlantic Ridge for the Census of Marine Life. He is shown here aboard the expedition ship, NOAA’s Henry B. Bigelow.
Smithsonian Zoologist Dr. Clyde Roper (rear) and museum specialist Mike Sweeney examine the mantle of a dead giant squid. Everything we know about giant squid comes from studying specimens found...
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...
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...
Ichthyologist John R. Paxton of the Australian Museum studies freshly caught lanternfishes. Paxton was on the team that solved the whalefish mystery .
How do you explain a scientific paper in three minutes or less? What if you were being judged by a bunch of middle-schoolers in classrooms around the world… and you only had a month to do it? The...
Dr. Stephen Cairns is a research zoologist and chair of the Department of Invertebrate Zoology at the Smithsonian’s National Museum of Natural History. His research focuses on the diversity,...
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...
Marine ecologist Dr. Jeremy Jackson and a team of researchers conducted an in-depth study of the effects of a 1986 oil spill on the coast of Panama. In this video , Dr. Jackson discusses the study,...
Often it's the tiniest organisms that do the most harm. One example is microscopic algae, which can grow rapidly to form harmful algal blooms . Such blooms (some are called "red tides") create...
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 ,...
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...
Marine biologist Mette Kaufman measures the temperature of a recently-drilled ice core . Variations in temperature at different points of the ice core provide information about the living conditions...
Dr. Candy Feller is framed by the roots of a mangrove tree on Panama’s Pacific coast. Mangrove trees grow particularly large in this area. More about mangroves can be found in our Mangroves featured...
Ice divers Katrin Iken (left) and Elizabeth Siddon are about to descend through a hole in the Arctic ice and into the frigid world below.
Did you know that over 17,000 species thrive in the deep sea where no light penetrates the ocean waves? Or that an old restaurant menu can teach us about the history of fish populations? Or that...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
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...
