The sightings came originally from the
Okeanos Ocean Research Foundation (Samuel S. Sadove, executive director; Okeanos is no longer in existence), and were recorded from commercial whale-watching vessels out of Montauk in late spring and summer of 1981–1994 (primarily the Finback I and Finback II). These sightings are heavily concentrated in the area between eastern Long Island and Block Island and during the whale-watching season, and therefore somewhat biased, but provide valuable information on several less-common species.
Data records that were missing time, animal count information, or located on land were excluded. One data record with two sighted species listed was also excluded.
