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

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

onEffort
character

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).

distance
numeric
Yes
No
Active
The number of reticles below the horizon using big eye binoculars (reticle 0 indicates the sighting is at the horizon) or the distance in meters if naked-eye between the animal (or center of group of animals) and the vessel when the cue was first seen by the observer.
120
distanceUnit
character
Yes
No
Active
The unit of measurement of the sighting distance: reticles (big eye binoculars) or meters (naked eye).
130
bearingToAnimals
Numeric
Yes
No
Active
Horizontal angle in degrees between the trackline and the line to the animal or group of animals when first sighted, even if a reliable species identification has not yet been made. The trackline is defined as the line of travel that the platform is actually doing, which may not necessarily be the proposed line that was in the original design. Assuming the platform is traveling forwards, the line of travel on the trackline, which is the front of the platform (e.g. bow of ship or front of plane) is at zero degrees bearing. During SEFSC vessel surveys, the observers scan the water from 10 degrees on the opposite side to 90 degrees and bearings are recorded from 0 to 90 on the left or right.

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.
