hugh: Seal "hugh" dive data.

In EdFarrell/animalTrack: Animal track reconstruction for high frequency 2-dimensional (2D) or 3-dimensional (3D) movement data

Description

A sample of recorded field data from a seal. The seal makes 6 dives with 5 surface intervals. Data have been pre-filtered but are in somewhat of an intermediate form for the purposes of examples within the animalTrack package.

a numeric vector of calibrated accelerometer Y-axis values scaled from -1 to +1g. A low-pass filter was applied in order to obtain "static" acceleration.

Az.dec

a numeric vector of calibrated accelerometer Z-axis values scaled from -1 to +1g. A low-pass filter was applied in order to obtain "static" acceleration.
