Recent Antarctic expeditions have documented climate-induced changes to emperor penguin habitats and impacts on how the penguins feed, breed, and raise their young.
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...
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.

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...
Auster gets ready to study fish predators at Gray’s Reef National Marine Sanctuary off the coast of Georgia.
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...
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...
Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
Picture this: clear, warm water bathing spectacular coral reefs , clouds of fish, circling sharks, and 17 scientists intent on studying the pristine tropical marine ecosystems of the Southern Line...
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...
Alvin, a human occupied vehicle (HOV), returns to the ship after a deep ocean dive to a seamount .
On May 31, 2009, this one-of-a-kind hybrid robotic vehicle reached the deepest part of the ocean—the Marianas Trench, located in the western Pacific Ocean, 10,902 meters (6.8 miles) below the surface...
