Doubled Your Impact for Our Ocean

Did you know that because of this caring community, more than 27,000 marine mammals have been rescued since the Center opened in 1975?

The animals are showing us that human activity is putting their lives at risk and threatening the health of our ocean. That’s why studying ocean health is key to helping marine mammals. And you can make a real difference today by doubling your impact for our ocean.

You can celebrate 27,000 animals rescued with your gift of just $27. Your life-saving donation will be matched dollar-for-dollar by a group of generous donors like you!
