What Is Ocean Acidification & Why Does It Matter?

As excess carbon dioxide is absorbed into the oceans, it is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain.

Lamont-Doherty Earth Observatory: Milestones in Climate Studies

Much of the modern understanding of climate has been shaped by pioneering studies done at Columbia University’s Lamont-Doherty Earth Observatory.

The Southern Ocean Is Breathing in Carbon Dioxide at a Healthy Rate

Since the late 1980s, the Southern Ocean’s rate of CO2 uptake appeared to have stagnated, alarming scientists. New data shows a recovery.

In northern winter, the Bering Sea, dividing Alaska and Siberia, becomes the most acidic region on earth (in purple) as shown in this February 2005 acidity map in pH scale. Temperate oceans are less acidic. The equatorial Pacific is left blank due to its high variability around El Niño and La Niña events. (Takahashi)
