In 2020, the Columbia River Inter-Tribal Fish Commission (CRITFC) assumed stewardship of the Center for Coastal Margin Observation and Prediction (CMOP) seeing it as a perfect complement to their efforts to combine cutting edge scientific research with traditional ecological knowledge in the estuary and ocean environments.
