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.


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 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.
