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. notPlanned 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_2275 2025-07-31T17:40:40-04:00 dataset Kopelman, A. and M.
