Kopelman, A. 2013. Opportunistic marine mammal sightings from commercial whale watching vessels, Montauk, New York 1981-1994. Data downloaded from OBIS-SEAMAP (http://seamap.env.duke.edu/dataset/1006) on yyyy-mm-dd.

Abstract

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.

Purpose

Supplemental information
