The sPAT is a pop-up archival transmitting tag (PAT tag, also known as a PSAT) specifically optimized for short-term survivorship studies. The sPAT uses a suite of sensors and algorithms to monitor the status of the tagged animal for up to 60 days.
The operational definition of “survivorship” is when the tag is still attached to a swimming animal 30 days after deployment.
Below are the physical specifications of the sPAT. A full description of these features is available on the downloadable sPAT Product Features (PDF).
