We are defenders of the ocean
ODA volunteers can be vastly different in age, backgrounds, skillsets, and interests. But we come together for one shared cause: To clean our oceans and make them safer for all life.

Crew and the Catch of the Day

Where we make a difference

 

ODA has two main geographical areas of operation. We have boats, divers, and onshore volunteers stationed in Southern California and the Hawaiian islands.

California

California

California has served as our homebase since ODA was founded in 2002. We remove debris of all kinds in the coastal waters and shorelines from San Diego to Ventura County.

Hawaii

Hawai'i

The high-volume of ocean debris in Hawai’i is alarming. Since 2017, we’ve had boats and volunteers on the Big Island and Oahu cleaning debris from beaches and in the water.

You are needed!
