Coastal Research and Education Society of Long Island, Inc.

Cetacean sightings data for the waters off Montauk for July through mid
September 2023

The Coastal Research and Education Society of Long Island is a non-profit
research and education organization. Our mission is: "To promote and
foster understanding and stewardship of coastal ecosystems through
research and education ." Part of our work is to observe, document, and
collect pertinent data and photographs of the cetaceans and sea bird
populations of NY and New England and to take people to see these
animals in the wild.

Since 1996 we have been offering incredible and successful single day and
multi-day offshore pelagic bird and whale observation trips.

A static view of vessel tracks is available. To show it online, go to "Layers" tab
