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...
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...
Using a drill, a team removes a chunk from the thick Arctic ice. Small samples are taken from where the ice meets liquid seawater. The ice is then melted for analysis.
Dr. Amy Baco-Taylor dives to deep-sea environments to study corals and the invertebrates that live in them. Learn how she became interested in deep-sea corals , and explore more in the multimedia...
The Woods Hole Oceanographic Institution's "Line W" program is conducting research to better understand how the oceans and the atmosphere work together to cause, and are affected by, climate...
Charles Potter (left) and Dr. James Mead of the Smithsonian perform a post-mortem examination on a goose-beaked whale specimen sent to them by colleagues at Portland State University.
The world beneath the Arctic ice is magical, but cold. Divers have to tolerate temperatures of 30 degrees Fahrenheit (about -2° Celsius.) To stay warm they wear thermal undergarments and use special...
White abalones are slow-moving, algae-eating mollusks. Rapid overharvesting since the 1970s has resulted in white abalones becoming the first marine invertebrate listed as endangered on the...
Two events made me passionate about deep-sea corals . One was my first submarine dive in a deep-sea coral bed off the Hawaiian island of Oahu. There was an incredibly lush community of corals and...
Watch as a team of wave chasers heads to Somoa where they search for an undersea river five kilometers beneath the ocean's surface. There they measured skyscraper-sized internal gravity waves, which...
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.
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 ,...
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...
Off the coast of North Carolina, Dr. Martha Nizinski and Johnson Sea Link pilot Phil Santos descend through the water column toward the target site. During this dive, Nizinski will observe and record...
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...
A scientific diver collects data on an underwater slate. Over the past several decades, scuba diving has become a serious, rigorous research tool that has an enormous impact on our understanding of...
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...
The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical...
