Abstract

During 6 June 2017 – 15 July 2017, the Northeast Fisheries Science Center (NEFSC) conducted aerial abundance surveys targeting marine mammals and sea turtles. The southwestern extent was New Jersey and the northeastern extent was off of Halifax, Nova Scotia, Canada. This survey covered waters from the coast line to about the 2000 m depth contour with a higher coverage over the New York State Offshore Planning Area. This survey coordinated with the SE aerial survey south of this study area in US waters. Track lines were flown 183 m (600 ft) above the water surface, at about 200 kph (110 knots). The two-independent team methodology was used to collect data. In Beaufort sea states of six and less, about 9,479 km of on-effort track lines were surveyed, where 95% of this effort was in Beaufort 3 and below.

Purpose

The objectives of this aerial flight was to collect the data needed to estimate abundance of cetaceans and turtles in the study area and to investigate how the animals’ distribution and abundance relate to their ecosystem.

Supplemental information

The survey code is TONE17SPR.

Perpendicular distance to the animal is not publicly available. Please contact the data provider to obtain this attribute.
