Devices for Tracking Marine Animal Movements

Have you ever wondered what habitats great white sharks choose or where dolphins and turtles prefer to migrate? For scientists and researchers, these questions are subjects of study. Observing the movements of a large number of animals of various species is possible thanks to the use of special tracking devices.

Data on animal movements allow scientists to obtain information about the migrations of both individual animals and entire populations. Monitoring results are extremely important for understanding the impact of global warming and anthropogenic effects on the natural habitats of animals, as well as for determining measures to prevent species extinction and the spread of diseases among animals.

Worldwide, scientists use small tracking devices that are attached to wild animals without causing them harm. Using GPS, tracking devices determine the animals' coordinates, store them, and send them via satellite communication to the appropriate databases. Data transmission intervals depend on the transmitters used and the specific tasks faced by researchers, and can be one minute, one hour, several hours, etc.

Information about the movements of individual animals helps researchers understand how animals navigate across the globe.

Use of tracking devices 

KELLER supplies 3L series pressure sensors for the production of miniature tracking devices specifically designed for studying marine animals. Thanks to the built-in sensor, such devices can withstand dives to depths of about 1000 meters and operate in a wide temperature range. In addition, installing 3L series sensors ensures cost-effective use of the devices for many years.
