Our mission is to promote and foster understanding and stewardship of coastal ecosystems through research and education


Autumn, Winter, and Spring are our SEAL WATCHING/RESEARCH seasons.

Join us at Cupsogue Beach, or the outer islands of eastern Long Island Sound to learn about, view, and photograph the wild seals of New York


Summer is our WHALE WATCHING/RESEARCH Season.

Travel with us from Montauk to near and offshore waters in search of whales, dolphins, porpoises, sea turtles, pelagic birds, and more.


The Coastal Research and Education Society of Long Island,  was founded in the summer of 1996 by a group of experts in marine mammal science, environmental sciences, education and conservation. CRESLI was formed for the purposes of conducting research, providing educational experiences and promoting conservation of coastal ecosystems.  Research and education are inextricably linked in all CRESLI activities. As such, CRESLI actively seeks cooperative alliances with researchers, educational institutions, and the participation of the public. Our pinniped and cetacean research projects, for example, utilize public whale watch cruises and seal walks as platforms for collecting data and educating the public at the same time. 

We are committed to our mission and have been since 1996. Join us on any of our excursions, lectures, activities to learn about our coastal waters and the ecosystems therein. Come out on trips top see the amazing diversity of marine mammals, sea turtles, pelagic birds, and other marine life. Become a member and/or a volunteer and join us in our work.

CRESLI is a non profit organization as defined in section 501 (c) (3) of the Internal Revenue Code
