65576 Effort Points 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 Describes characteristics of when observations are attempted. To describe the effort made to observe the marine mammals. Data Table Yes Effort Table 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.
