FUNDING
The tissue samples were collected during tagging activities sponsored by ONR, IWC, IUCN, Navy Fleet Command, Exxon Neftgas, and private donors to the Marine Mammal Institute Endowment. This project is funded by the Marine Mammal Institute's Oregon Gray Whale License Plate Program. We deeply appreciate the support of the Oregonians who purchased or renewed their Coastal Playground license plate!
