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 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.
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!
Fuel ODA's boats, and sustain our efforts to clean our oceans.
Dive in with us - on our boats, on shore, and from home.
