TDR10-DD-278 Product Information



The Daily Diary will be retired on 31-December-2022.

The Daily Diary tag offers the most sensors among Wildlife Computers archival tags. These additional sensors (accelerometer, magnetometer, and speed) allow for an expanding field of applications, including three-dimensional track reconstruction and energetic inference. The user can choose to sample the three-axis accelerometer up to 32 Hz, and the three-axis magnetometer up to 8 Hz. This tag also includes the standard archival sensors for depth, temperature, and light level.

The additional sensors can be used to estimate a range of behavioral characteristics. The accelerometer can be used to differentiate between movement and resting behavior, and can also be used to identify foraging events. Orientation and body position can also be derived by combining attitudinal information (tilt and roll) from the accelerometer with magnetometer readings. Combining changes in depth with the paddle wheel speed measurements will also allow the derivation of the horizontal and vertical components of the animal’s swimming speed.
