Drifters deployed into the Gulf of Mexico sent location information back to scientists through a GPS satellite. Some of the 5.7 million data points about the drifters locations are seen in this map...
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...
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...
The research submersible Alvin uses bright lights to illuminate the dark seafloor. Built in 1964, it has made more than 4,400 dives. It can carry two scientists and a pilot as deep as 4,500 meters (...
A boat full of SCOPE drifters waits to release small, biodegradable buoys that will travel throughout the Gulf of Mexico and send GPS coordinates to researchers. This is the second experiment by...
The first underwater robotic vehicle—or “glider”—to cross an ocean is the centerpiece of a new exhibit at the Smithsonian. Rutgers University professor Scott Glenn explains that the technology is now...
Sponsored by the United Nations, the Global Ocean Observing System is committed to sharing observations about the ocean to all nations. Some of the data they collect comes from buoys like the one...
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...

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...
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...
The remotely operated vehicle ROPOS recovers a volcano monitor from NOAA’s New Millennium Observatory on the Juan de Fuca Ridge, off the coast of the Northwest United States. The station was set up...
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...
Chilean and Smithsonian paleontologists study several fossil whale skeletons at Cerro Ballena, next to the Pan-American Highway in Atacama Region, Chile, in 2011. The fossils were discovered when the...
