Cetacean and sea turtle visual observations using line-transect survey methods aboard a NOAA DeHavilland DHC-6 Twin Otter (TO) aircraft in the Gulf of Mexico, during the Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPPS survey TO17Su) from 6/29/2017 to 8/17/2017.
Data Set
Completed
2021-10
Marine mammal (cetacean) cue (when recorded) and sighting data with calculated perpendicular distances (sightingDistanceInMeters) for the forward team (T1).
Please note that cues to marine mammal sightings are not necessarily recorded for all sightings.
Main goal of this file is to provide platform location at time of cue and sighting recording, and perpendicular distance of the sighting in relation to the platform based on vertical angle and observation height.

Unique identifier to a survey (vessel or aircraft based) event. For vessel survey: composed of the vessel's acronym followed by a 2-digit survey year and a 2-digit consecutive mission-number on that vessel (a.k.a cruise code).
Cruise name / Cruise Number
Made up of a combination of
a two character Boat Abbreviation : GU = Gordon Gunther
a two digit year: 18 for 2018
a two digit cruise number: 01 for first cruise of the year

Active
Unique numeric identifier for each survey effort point recorded at regular time intervals. For vessel surveys: approximately every 30 seconds. For aerial surveys: approximately every 10 seconds. This is the indexing number that allows each marine mammal sighting, non-mammal occurence and cue to be linked to the effort points. See also dwc:eventID

Yes
No
Active
Effort status designating if observers were on effort (e.g. observers actively scanning for marine mammals through the big eye binoculars with the vessel steadily cruising on the trackline) or off effort (e.g. observers searching naked eyed, whenever the ship was maneuvering and turning onto a new trackline, if other operations were taking place, during bad weather and whenever observers were not actively searching for cetaceans through the big eyes) at the moment of data recording. Y=Yes (on effort), N=No (off effort). For vessel survey: #1=vessel's Flying Bridge, #2=vessel's Bridge Wing (a.k.a. bridge deck).

Active
Interval for the sighting based on markings on the belly port splitting the window into sections with numbers from 1 to 4 and letters to designate the left (L) or right (R) side in relation to the plane, with 1 being closest to the center of the window, i.e., closest to the trackline. Observers record the section of the window when the sighting is directly under the aircraft.

One-character string to flag only the initial sighting records which can be used in density and abundance estimation. Opportunistic and subsequent sighting records can be included in the dataset, but these are easily identified from this term for exclusion from abundance and density modeling. The fixed vocabulary terms are: F = first observation sighting on transect, O = opportunistic sighting, S = subsequent sighting either on or off transect, Null = for position-only records or non-VLTS datasets.
