A class of digital recording tags has been developed that can be attached to marine mammals and thereby record the animals movements and vocalizations over a period of 24 hours or more. Examples of such tags are Dtag, CritterCam, Daily Diary and Acousonde. These tags contain accelerometers, magnetometers and pressure sensors.

TrackPlot™ is a software package designed to help analyze kinematic patterns from tag data. This package allows for novel kinematic patterns to be rapidly identified and analyzed. It also allows for the pseudo-track to be georeferenced if a set of surface fix locations exist. And it allows for sound to be played synchronously with movement.

This software is still somewhat experimental. Please contact Colin Ware for help in using it.
