66282 Entity Published / External 65831 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 TO18Fa) from 10/12/2018 to 11/28/2018. Data Set Completed 2021 Effort points with sampling conditions collected by the aft team (T2) effort-point data; main goal is to provide sampling conditions recorded by observers and platform movement during marine mammal visual observations by the aft team (T2) Within files for each team, effort points can be cross-referenced to cues, sightings, and non-mammal occurrences via eventID Data Table Yes Effort points with sampling conditions collected by the aft team 10 surveyEventID Character 6 6 Yes No Active 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 15 eventID numeric Yes No 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.
