CRESLI, the Coastal Research and Education Society of Long Island (https://cresli.org), is a non-profit research and education organization with the following mission: To promote and foster understanding and stewardship of coastal ecosystems through research and education. I am CRESLI's president and am also a retired professor and population ecologist, studying the populations of whales and seals in the waters of NY. The photographs here are those taken on research and public trips that I lead to observe our marine mammals and pelagic birds.
