Dataset credits: Coastal Research and Education Society of Long Island, Inc. Abstract: These data were collected during local (5-8 hour) whale watching trips conducted by the Viking Fleet and CRESLI. Trips originated from Montauk Harbor in Montauk, New York and occurred regularly from 1997-2002 and again from 2009 - present, during July, August and early September. The data were collected during efforts to gather information about the distribution, abundance, habitat use and site fidelity of cetaceans in the waters around Montauk, New York. The general public were educated, and volunteers were involved in collecting data, as citizen scientists. The data are maintained by CRESLI and are submitted to appropriate catalogs when possible.

Our mission is: "To promote and foster understanding and stewardship of coastal ecosystems through research and education ." Part of our work is to observe and document the whale and sea bird populations of NY and New England and to take people to see these animals in the wild. Since 2002 we have been offering incredible and successful multi-day offshore pelagic bird and whale observation trips. asNeeded Arthur Kopelman Coastal Research and Education Society of Long Island Primary contact president@cresli.org www.cresli.org NA NA NA Arthur Kopelman owner Marianne McNamara originator NA zd_896 2025-07-31T15:50:28-04:00 dataset Kopelman, A. and M.
