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 . That small change in acidity is enough to dissolve the shells...

A fleet of underwater floats called Argo is deployed at more than 3,000 spots around the world. The floats transmit...
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...
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...
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...
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,...
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...
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...
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...
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...
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...
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...
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...
CREDIT: Provided by Rutgers University Glider Technology Now Used to Study Oil Spill in Gulf of Mexico The first underwater robotic vehicle—or “glider”—to cross an ocean is the centerpiece of a new...
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...
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...
Ultraviolet light illuminates the growth rings in a cross-section of a 44-year-old deep-sea coral ( Primnoa resedaeformis ) collected off the coast of Newfoundland at about 1,300 feet (400 meters)...
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 . That small change in acidity is...
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...
Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't...
