Fish

Surgically implanted TDR-Mk9 archival (electronic data storage) tags provide a record of ambient and internal body temperature, pressure, and light. They are placed into the peritoneal cavity of the fish, with the light and temperature sensor stalk protruding outside the body through an incision in the abdominal wall. Latitude and longitude geolocation estimates are possible from the light intensity data, augmented with information on sea surface temperature and depth.

Our Pop-up Archival Transmitting tags (PAT or PSAT) also provide fisheries-independent information by allowing the remote recovery of data from non-surface-oriented marine animals. Researchers attach the tags externally and program release for when certain parameters are met. Upon release, the tags float to the surface and transmit to the Argos satellite network. Pop-up tags are used to study animals such as tuna, sharks, marlin, swordfish, halibut, and eels.

*** Tag will sample for over 8 years based on sampling depth, body temperature, external temperature and light every 30 seconds. Maximum deployment length is limited by memory, thus depends upon the user-programmed sampling rates.
