As part of the AMAPPS program, the Southeast Fisheries
Science Center conducted shipboard surveys of continental
slope and shelf break waters along the US East Coast from
Central Florida to Delaware during 30 June – 19 August,
2016 (designated Cruise code GU16-05). The marine mammal
survey was designed for analysis using Distance sampling,
and a two-team (independent observer) approach was used
correct for perception bias in resulting abundance
estimates. Team 1 was stationed on the vessel's flying
bridge (height above the water 13.9 m) and team 2 was
located on the bridge wings (height above the water 11.2
m). Between 20 - 24 August the ship transited into the
Gulf of Mexico and only team 1 was active.


The goal of the survey was to conduct line-transect surveys
using the Distance sampling approach to estimate the
abundance and spatial distribution of cetaceans in the
continental slope and shelf break waters along the US East

Supplemental information

Trip ID / Dataset ID of this dataset is GU1605.

Perpendicular distance to the animal is not publicly
The dataset is accompanied by transect (effort) data
is provided as a separate file.
Sightings included were detected on-effort by the flying
bridge only or by both the flying bridge and bridge wing
teams; you may request the full dataset and sightings
including opportunistic ones directly to the provider.
