Starksia blennies, small coral reef fish, have been well-studied for more than 100 years. But Smithsonian scientists discovered that what were thought to be three species of the fish are actually 10...
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...
Brian Skerry, an award winning photographer for National Geographic, explores the underwater world searching for the perfect photo. But getting that photo is never easy. Read more from Brian about...
Studies along the Northwest Atlantic Ocean shelf break- the transition from continental shelf to slope- by researchers from Woods Hole Oceanographic Institution and Rutgers University are revealing...
Expedition data went to the Arctic Ocean Diversity database of the Census of Marine Life to establish a baseline that will help to document change in the poorly known Arctic Ocean. Scientist Kevin...
What happens to deep-sea coral samples after they are collected? In this image gallery, see some of the ways ocean scientists sort, measure, photograph, and study them. Learn more in the multimedia...
Scientists talk about the experience of exploring the ocean in this excerpt from the Deep Ocean Explorers video. More about deep ocean exploration can be found in our Deep Ocean Exploration featured...
Researcher Aimee Ellison tests samples for DNA barcoding at the Gump Field Station on Moorea.
"Inside the Open Ocean: Blue Water Diving" produced by Woods Hole Oceanographic Institution (WHOI) , describes a specialized diving technique that lets biologists study the ocean's most fragile...
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...
Researchers can study ocean acidification in the lab by rearing organisms in seawater with variable pH and measuring if they grow, eat, breathe, reproduce, or develop differently. It's common, for...
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...
My father once told me that the world is divided into two kinds of people: those who believe that the world is divided into two kinds of people and those who don’t. Wherever you come down on this...
Peter Auster and colleagues direct a Remotely Operated Vehicle (ROV) dive on the New England Seamounts. Three teams composed of three scientists and four ROV engineers take two 4-hour watches every...
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...
Dr. Francisco Chavez of the Monterey Bay Aquarium Research Institute estimates that a million tons of CO 2 enter the ocean hourly. His studies in Peru explore the phenomenon of ocean acidification ,...
For more than two centuries, Boston Harbor has been a dumping ground. In 1773, colonists famously dumped shiploads of tea to protest taxes. But in recent decades, the harbor has received less tea and...
Deep-sea coral beds are true biodiversity hotspots. It’s urgent that we study these extreme environments because we know so little about them, because they are important communities for so many deep-...
