SPLASH-F-391

The SPLASH-F-391 is the first shape in our updated SPLASH product line. Our updated SPLASH (formerly SPLASH10) tags incorporate the last ten years of researcher input to create a tag with model-ready temperature profiles and fully integrated with the Wildlife Computers Data Portal.

The SPLASH-F-391 (Fastloc®) tags is a data-archiving, satellite transmitting tags designed for tracking vertical and horizontal movements of free-range marine animals. A SPLASH-F-391 tag works best for researchers conducting fine-scale movement studies on diving animals like pinnipeds but also for studies involving oceanographic research.

Fastloc technology is what sets this tag apart. Fastloc uses GPS to provide highly accurate locations in under a second. Fastloc allows for fine-scale locations on animals that surface too quickly for a traditional GPS or Argos fix— Fastloc acquires positions every few minutes compared to a maximum of a few dozen a day with Argos-only tags.

Key Benefits of Fastloc:

  • Highly accurate—precise to 20 m.
  • Fast acquisition—even after prolonged sleep, a location can be achieved in a fraction of a second. Very little surface exposure is needed.
  • Validation pre-storing—only successful locations are saved and transmitted to allow for dynamic scheduling in case of failure.
  • Flexible scheduling—fixes can be scheduled at regular intervals or duty-cycled depending on the day or season.
  • Many locations possible—hundreds achievable per day for a higher resolution track.

Other Key Features Available in the SPLASH-F-391

  • Improved Temperature Profiles with Standard Oceanographic Levels—SPLASH-F-391 offers model-ready water column profiles coupled with GPS-quality locations making it ready for animals-as-ocean-observers.
  • Efficient summary of behavior with Empirical Cumulative Distribution (ECD) of time-at-depth.
  • Highly Customizable Data Collection and Transmitting Schedule—researchers have the power to customize and prioritize data collection and transmission to capture the information that is most significant for the project. Deployments can be tailored to achieve unique experimental objectives. Flexible transmissions provide the ability to extend the life of the tag by focusing on specific seasons or times of the year.
  • The Portal Advantage—SPLASH-F tags are supported by the Wildlife Computers Data Portal, a collection of data management tools and services. Developed specifically for the display and investigation of data from Wildlife Computers tags, the data portal streamlines the processes of acquiring, preserving, and sharing data services. Fastloc Solver is built right in so you can schedule automatic processing to the most reason Fastloc locations so they are ready whenever you are. The portal helps collect, prepare, and analyze the data returned from the tag—via Argos or the archive. Data are easily sorted, filtered, searched, uploaded, and shared. You can see a Google Earth display of your deployment track, color-coded to show the relative age of each location. You can also set up a live KMZ to get data into your own monitoring system.
