Metadata
This section includes fields that describe the angle at which the animal(s) dive. Note that this section refers to the descent phase of a dive; the following section (Surfacing Angle) corresponds to the ascent phase of the dive.
 Minimum Dive Angle
DA_MinDiveAngle(deg): The minimum angle at which the animal(s) descend (degrees).
 Maximum Dive Angle
DA_MaxDiveAngle(deg): The maximum angle at which the animal(s) descend (degrees).
 Mean Dive Angle
DA_MeanDiveAngle(deg): The mean or average angle at which the animal(s) descend (degrees).
 Median Dive Angle
DA_MedianDiveAngle(deg): The middle value in the distribution of the dive angles (degrees). If there is an even number of dive angle values, it is the average of the two middle values.
 Mode Dive Angle
DA_ModeDiveAngle(deg): The most common dive angle value; in the frequency distribution, the dive angle with the greatest number of frequencies (degrees).
 Gamma Distribution Alpha
DA_GammaDistAlpha: The shape parameter of the gamma distribution of dive angles, determined by submitting data and fitting the raw data in a statistical package.
 Gamma Distribution Beta
DA_GammaDistBeta: The rate parameter, equal to 1/Θ (the scale parameter), of the gamma distribution of dive angles, determined by submitting data and fitting the raw data in a statistical package.
 Dive Angle Standard Deviation
DA_DiveAngleStdDev: To express the degree of dispersion in the dive angle data, the standard deviation (square root of the variance) should be entered (degrees).
 Comments
DA_Comments: Freeform field to note complications with data entry, information to review at a later date, etc.
