The American Cetacean Society protects whales, dolphins, porpoises, and their habitats through public education, research grants, and conservation actions.
Founded in 1967, the American Cetacean Society (ACS) is the oldest whale conservation group in the world. ACS is a 501(c)(3) non-profit organization with an office in San Pedro, California and chapters in Los Angeles, Orange County, Puget Sound (Seattle), Monterey, San Francisco, and the Channel Islands (Santa Barbara / Ventura). Our members live throughout the United States and in more than 20 countries.
We take our responsibility as participants in the web of life seriously, and volunteer our time and resources to not just protect whales, dolphins and porpoises, but to promote the health of the oceans and ultimately our planet as well.
