Geolocation, Depth and Temperature Loggers
[Introduction] [Geolocators] [Temperature Depth Recorders]

Introduction

Our sister company, Lotek, have been building data storage tags for many years. Initially developed for fish, they are now being used to investigate behaviour and migration paths of many birds that are too small to carry satellite tags.

Geolocators are tags capable of measuring and storing data on light levels. Once retrieved this data can be used to calculate the latitude and longitude using a process known as light-based geolocation. Alternatively Temperature Depth Recorders (TDR tags) can tell you about the diving activities of seabirds. Despite their small size, these tags have enough battery and memory capacity to store several years’ worth of data.

Until now species studied have been restricted to those where there is a good chance of recovery. Biotrack and Lotek are now working together to improve the recovery of these tags by including a VHF radio-tag to find the tag. To keep weight to a minimum the radio-tag is set to start when the individual returns to the trapping area, thus avoiding the need for power (and therefore battery weight) when away. If you would like to know more about this please contact us.

For more examples of Data Storage Tags and how they have been used please see the Lotek Website
