Cue counts of whale blows


Cues are treated as an indirect count, requiring the use of multipliers.


A data.frame with 109 rows and 15 variables.


Because whale blows disappear instantaneously, there is no need to measure a decay rate. However a cue production rate (blows per individual per unit time) is required, as is a measure of variability of that rate.


There are two other nuances in this survey. Even though the survey is taking place on a moving ship, effort is measured as amount of time scanning for blows. In some instances, it is not possible for the observer to scan the sea all around them as view may be restricted by the ship's superstructure. Here a sampling fraction multiplier is employed to deal with restricted vision. Units of measure of cue.rate and Search.time must be equal.
