The Disturbance data contains a record of observed disturbances.
The columns included in the dataset are:
Date: Date of observations. Format is yyyy-mm-dd
VP Start: Start time of all vantage point observations (flight, count, disturbance)
VP End: End of all vantage point observations
Observer: Initial of the observer
VP: The Vnatage point location (see Vantage Point resource for location data)
Dist Watch start: Start of observation for disturbance
Dist Watch end: End of disturbance observation
Disturbance Type: Description of the type of disturbance observed, including record if no disturbances were observed during the disturbance watch period.
Observation detail: Freetext field describing vessels or events causing disturbance.
enter and left L1-4, and R1-4 Are timestamps for the entry and exit from observation sectors of the disturbance identified.
The observation areas describes a 90 degree arch split in a left and right 45 degree arch. The number indicates distance from vantage point (0-250m, 250-500m, 500-1000m, and 1000-2000m). This R3 indicates the righthand observation sector with a distance beetween 500 and 1000m from the vantage point.
Please consult the report methodology section for detail on the observation areas and methodology.
