Temperature & Chemistry

How and why do ocean temperatures fluctuate throughout the ocean? Not only are there massive temperature changes in the ocean (called a thermocline), but also swift changes in salt, oxygen and other chemicals that can tell scientists a lot.

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...
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...
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...

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...
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...
