Submit Sightings of Harbor Porpoise and other Cetaceans


There are two ways you can submit "opportunistic" sightings of harbor porpoise, Dall's porpoise and Pacific white-sided dolphins.

1. Send us an email with the following information: date, time, location, duration, activity and number of porpoises.

2. Via our iNaturalist Harbor Porpoise Project (instructions here)

We are particularly interested to know if you see any very large groups of harbor porpoise! If you do, please send us a report, or call the office number below as soon as possible.
