LATEST CATCH

The first time biologist Mandy Joye dove to the deep sea in the Johnson-Sea-Link submersible (pictured here), she had never seen the bubbles of a methane seep. But after that fateful day in 1994, she was entranced. Instead of...

DIVE DEEPER

New technology is making it possible for scientists to go where they’ve never gone before, the depths of the icy Arctic...
This radio device is used to track North Atlantic right whales. Suction cups hold the device to a whale's back, where it records data such as depth, water, temperature, and underwater sounds. These...
The bright, brilliant swirls of blue and green seen from space are a phytoplankton bloom in the Barents Sea. Phytoplankton can bloom like this, rapidly growing and reproducing, because of a sudden...
On March 1, 1954, the United States military tested nuclear bombs in the ocean around Bikini Atoll in the Pacific Ocean to see what kind of damage they would do to ships. The largest explosion was...
Lights attached to this modern deep-sea camera system enable scientists to capture detailed images of deep-sea coral reefs and their inhabitants in otherwise dark water. Learn more about how ocean...
Microbes are some of the most important organisms in the sea. These miniscule organisms provide an important link in the food web between the dissolved nutrients in the ocean and larger organisms...
This video, produced by Waterlust, shows how the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) uses drifters to collect important data about the ocean...
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...
Searching for useful chemicals, marine scientists grow bacteria associated with deep-sea coral on nutrient agar to identify the bacteria and test their metabolic and biochemical capabilities. Some...
Last week, Smithsonian research zoologists Dr. Jerry Harasewych and Dr. Martha Nizinski were in Curaçao looking for deep-sea marine gastropods and decapod crustaceans , respectively. I learned they...
In 2011, Oceana researchers spent two months surveying life and conditions in the Baltic Sea. The team covered more than 7,000 nautical miles and completed more than 130 dives. The data, samples,...
New technology is making it possible for scientists to go where they’ve never gone before, the depths of the icy Arctic Ocean . By collecting organisms and mapping the seafloor, researchers can...
In the spring of 2011, a research crew from Oceana spent two months in the brackish Baltic Sea . The Baltic faces challenges from pollution, algae blooms, over fishing, and invasive species. Oceana...
Smithsonian researchers are using this five-person submersible to study the biodiversity of the deep reefs of Curaçao in the southern Caribbean. Read about their adventures in the Summer in a Sub...
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-...
Two divers, one in an atmospheric dive suit (left) and the other in standard dive gear (right), prepare to explore the Lusitania shipwreck in 1935. Over the decades, diving gear has evolved and...
Traveling aboard the Charles W. Morgan , a 173-year-old whaling ship on its 38th Voyage, I’m struck by its paradox: this vessel which spent years chasing and killing whales is now helping us to study...
Ever since fourth grade I’ve wanted to explore the creatures and landscapes of the deep ocean in a submersible. It took awhile, but I finally got my chance this summer as part of the Deep Reef...
