The Orca Network has been monitoring the Southern Resident and Transient orcas of the Salish Sea (from Puget Sound to the Straits of Georgia, Canada) for over 40 years. They have helped create an identification system for the orcas. They share observations and sightings with the public via the Inteernet daily, sometimes on almost an hourly basis, hold educational workshops, share calls heard on hydrophones, etc. I believe the most important work they have/are doing is in the research field; they collect data which is then shared with governmental agencies (NOAA) and other research organizations. This has already led to changes in laws to help protect these endangered species, and may possibly contribute to further changes in statutes that will affect the entire nation.
