This presentation highlights Finding Hal, a citizen science initiative designed to support the recovery of the critically endangered white abalone (Haliotis sorenseni) throughout the Southern California Bight. Once abundant along the California coast, white abalone populations have declined to the brink of extinction, making every confirmed observation valuable for conservation and recovery efforts. Through the Wanted Alive! White Abalone campaign, recreational divers are empowered to contribute directly to marine conservation by documenting abalone sightings, learning species identification skills, and submitting field observations that may help locate remnant wild individuals. Attendees will learn how community science can expand monitoring capacity across vast marine habitats, the importance of accurate species identification, and how partnerships among NOAA, Aquarium of the Pacific, and the diving community are helping advance endangered species recovery.
