65432 Group Sizes Entity Published / External 65428 Cetacean visual observations using line-transect survey methods onboard the NOAA Ship Gordon Gunter in the Gulf of Mexico, January through March 2018, GoMMAPPS survey (GU1801) Data Set Completed 2021-10 Group size estimations for marine mammal sightings; Main goal is to provide values estimated by observers Data Table Yes Group size estimations for marine mammal sightings 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 20 sightingNumber numeric Yes No Active The numeric identifier to the cetacean sighting 30 scientificName character Yes No Active The full scientific name or lowest level taxonomic rank that could be determined for the sighting. See also dwc:scientificName 40 vernacularName character Yes No Active The common or vernacular name for the species or lowest level taxonomic rank that could be determined for the sighting. YYYY-MM-DDHH24:MN:SS 50 recordedBy numeric 4 Yes No Active Numeric code for each observer 60 observersCountsMin Numeric 3 Yes No Active Value estimated by the observer to reflect the minimum number of animals in the sighting. 65 observersCountsBest Numeric 2 Yes No Active Value estimated by the observer to reflect the most accurate number of animals in the sighting 70 observersCountsMax Numeric 3 Yes No Active Value estimated by the observer to reflect the maximum number of animals in the sighting. 75 typeVLTS character Yes No Active 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. 85 platformVLTS character 1 1 Yes No Active One-character string to flag survey platform type for visual line transect surveys. For aerial surveys: All records flagged “A” For boat-based surveys: All records flagged “B”. 90 higherInstitutionCode Character Yes No Active Institution codes, in the form of abbreviated institution names, separated by semicolons, that define the hierarchy of institutions within which the data originator operates. Includes the originating institution as the lowest level (rightmost) code. 110 permitnumber Character Yes No Active The permit number which gives authority /permission for collection of the marine mammal data. 240 platformAttributes character Yes No Active Model, name and/or other proper characteristics of the platform where the survey was conducted. For vessel: e.g. NOAA Ship Gordon Gunter, NOAA Ship Pisces. For aerial survey: e.g. NOAA De Havilland DHC-6-300 Twin Otter. 250 relatedProjectProgram character 100 Yes No Active Official project and/or program under which the survey was conducted (e.g. AMAPPS, GoMMAPPS). If applicable. 270 samplingProtocol character Yes No Active The names of, references to, or descriptions of the methods or protocols used during an Event. Public URL to survey and/or cruise reports if available.
