Over a 10-year period NOAA scientists have collected 72,000 seawater samples, and their data show that the ocean is becoming more acidic because of climate change -caused warming. That small shift is enough to...

It’s not an easy question to answer. In the lab, scientists can set up a series of seawater tanks with a variety of pH levels to figure out how different species react to more acidic water, observing...
The first unmanned, underwater robot or glider Scarlet Knight maneuvers through the dangerous opposing and circular currents in swirling eddy fields of the Atlantic Ocean to collect data below the...
On April 20, 2010, the Deepwater Horizon oil rig exploded, opening up a well that pumped nearly 5 million barrels of oil into the ocean. It was the largest spill in U.S. history. In this presentation...
The Baltic is a brackish sea, a unique combination of freshwater from rivers in the surrounding countries and salt water from the ocean. The low salinity levels are one of the factors that determine...
Fossil fuels that power our cars, homes, and businesses add carbon dioxide (CO2) to the atmosphere. The ocean absorbs large portions of this CO2 and acts as a buffer against climate change . But, Dr...
How will changes in temperature affect glaciers and ice sheets? Dr. Sarah Das from the Woods Hole Oceanographic Institution explores this phenomenon first hand in Greenland, where she studies how the...
Globotruncana falsostuarti -- a foram that lived about 75 million years ago, during the Cretaceous Period, from southeastern Tanzania. By measuring the chemistry in the shell, scientists can estimate...
Oceanographers divide the ocean into three broad zones. Together, they could hide 20 Washington Monuments stacked on top of each other. Each zone has a different mix of species adapted to its light...
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 Deepwater Horizon disaster has imperiled the ecosystem along the U.S. Gulf Coast. Most oil spills have occurred at the ocean surface. This one, originating at the ocean floor and rising up...
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...
Marine biologist Mette Kaufman measures the temperature of a recently-drilled ice core . Variations in temperature at different points of the ice core provide information about the living conditions...
A screen capture from NOAA's NowCoast website which displays real-time weather data, including current speeds, projected hazards, temperature and wind speed. Real-time data is helping scientists work...
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...
Many species are being recruited to gather data in hidden corners of the ocean. From sea lions to sharks, these animals can collect information about how climate change is affecting ocean temperature...
The Woods Hole Oceanographic Institution's "Line W" program is conducting research to better understand how the oceans and the atmosphere work together to cause, and are affected by, climate...
