ARCGEO Geolocator-TDRs for birds

  • Product Type Icon Tag

Geolocation and diving behaviour

Following on from the success of the LAT2000 Series, the ARC range is able to record the same data, but with an impressive 16 MB of memory in only 3.4 g (TBC). More detail can be recorded on the diving behaviour, or data can be collected over a much longer period of time.

ARC tags are easily mounted onto a ring on the leg of a waterbird, for minimal impact, and to record when birds are on the water as well as when they are diving for food.


Options

  • Sensors: Light for geolocation, Pressure for diving, Temperature, Wet/Dry.
  • Product Features

    Sensors:
    Recording light and temperature data for geolocation, plus pressure and wet/dry for diving behaviour.

    Up to 8 Sequential Logs:
    To record the data most appropriate for the time of year, breeding cycle.

    Geolocation and depth visualisation:
    LAT Viewer Studio software (without maps) is provided with the ARC TagTalk, so that sophisticated Template Fit or Threshold geolocation analysis can be run or dive profile, light and temperature data can be visually explored. Geolocation tracks can be exported to GoogleEarth or as spreadsheets.

    Tag Storage:
    ARC tags can be stored for the next season, with much of the capacity saved, provided the tag is in a “Stopped” status. This is a great improvement on other tags that drastically deplete their capacity even if not deployed.

    Data Safety:
    Memory contents retained for 25 years ensuring data retention even if the tag is recovered years after the battery is exhausted.

  • Product Applications

    These ARCGEOs are designed for seabird researchers interested in where birds go, how often they are on the water, how frequently and to what depth do they dive and the temperatures they experience.

    While light-based geolocation is not as accurate as GPS, the technique works with relatively small tags attached to the legs of seabirds, so the deployments can be much longer than GPS tags taped to feathers.  Over the last decade, researchers have made exciting discoveries about migration from light-based geolocation.

    Combining dive depth and frequency, with time spent on the water can reveal even more about what those seabirds do when they are away from the breeding colonies.  This information has the potential to reveal important feeding areas, and helps us understand the  energetic demands seabirds endure.
