New technology is making it possible for scientists to go where they’ve never gone before, the depths of the icy Arctic...
By Emily Frost Throw a message in a bottle into the vast ocean and where does it go? The answer to this question is not just a romantic curiosity. Thinking about where a small floating item might end...
AUV Sentry is an autonomous underwater vehicle (AUV) that was used in the Gulf of Mexico directly after the Deepwater Horizon oil spill in 2010. Researchers rushed to get to the Gulf as quickly as...
A fleet of underwater floats called Argo is deployed at more than 3,000 spots around the world. The floats transmit information about water temperature, salinity, and pressure which scientists use to...
This small drone helped scientists follow a trail of pink dye tracking water movement below the ocean surface in the Gulf of Mexico. Along with pre-placed underwater sensors, a helicopter, and a kite...
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...
Algae, like all organisms, normally grow in balance with their ecosystems, limited by the amount of nutrients in the water. But sometimes, certain species of algae reproduce so rapidly that they...
Tectitethya crypta (formerly known as Cryptotheca crypta ) is a large, shallow-water sponge found in the Caribbean. It was first studied for medical purposes in the 1950s when few scientists or...
When oil gushed out of the Deepwater Horizon oil rig in the Gulf of Mexico in spring and summer 2010, it was all anyone could talk about. Several years on, it’s much further from our minds—but that...
The robotic arm of a Pisces submersible collects a gold coral colony ( Gerardia sp.) during a research cruise in the Hawaiian Islands. Ocean scientists have radiocarbon-dated some Gerardia specimens...

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...
The Curasub departs for a deep sea dive, up to 1,000 feet off the island of Curaçao, where this sub is located. Smithsonian's Deep Sea Observation Project (DROP) is exploring these waters and using...
Come along as scientist Dr. Brendan Roark narrates a submersible dive to collect and study deep-sea corals. Roark studies deep-sea corals to understand the history of the ocean and past ocean...
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...
The Baltic’s waters are so frigid that the sandy seabed was often frozen during Oceana's 2011 expedition. The divers’ underwater cameras had to be put on automatic settings to take photos, as their...
NOAA is working with students across the globe to place floating buoys throughout the ocean through their Adopt a Drifter Program . The buoys will drift with the help of ocean currents and record 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...
