Princepajaro, a male California sea lion, swims in a pool during treatment for leptospirosis at The Marine Mammal Center in Sausalito, CA. When a leptospirosis outbreak occurs, the Center’s scientists study the disease to learn more about what causes an outbreak and how we can improve treatment for infected animals.

Major Disease Outbreak Strikes California Sea Lions

Leptospirosis afflicts sea lions on a semi-regular cycle, but warming waters and migrating fish could make the marine mammals more susceptible

Species in the Northwest Atlantic, like this red tree coral, are threatened by ocean acidification, which may be causing the dissolution of the sea floor.

Parts of the Ocean Floor Are Disintegrating—And It's Our Fault

A new study has found that calcium carbonate on the sea floor is dissolving too quickly in an effort to keep up with excess carbon dioxide

Seagrass plants have a large capacity for absorbing and storing carbon on the seafloor.

Underwater Meadows of Seagrass Could Be the Ideal Carbon Sinks

Many ecosystems absorb and store vast amounts of carbon dioxide, and seagrass is one of the most efficient natural carbon storage environments
