TDR-Mk9-329

TDR-Mk9-329

Wildlife Computers Mk9 Time-Depth Recorders (TDR-Mk9) are small archival tags best designed for studies involving marine animals where the tag and/or animal can be recovered.

Overview

Key advantages of the TDR-Mk9 include:

  • Small size—it is Wildlife Computers smallest data archiving tag and it can withstand 1000 meters of pressure. Additional configurations withstand up to 2000 meters.
  • Long life—efficient power management allows tags to function for multi-year deployments.
  • Cost-effective—TDR tags are a cost-effective option for studies where tags can be recovered.
  • User-programmable sampling protocols—users can specify which sensors to sample and at what interval.
  • Tag activation—the tag can be turned on and off with a magnet. The LED flash sequence indicates whether the tag is in standby mode or deployed.
  • Data decoding, analysis, and communication—Wildlife Computers provides easy-to-use software that allows the user to set up the tag for deployment, download the data after recovery, and aid in the analysis of the data.
  • Geolocation using light-level—Wildlife Computers GPE3 estimates daily longitude and latitude from recorded light-level curves.

Data Products

The TDR-Mk9 measures depth, temperature, and light-level and also differentiate wet or dry conditions at a user-configured sampling interval.

Light-level and a second temperature sensor can be added to a sensor stalk making it suitable for both external attachment and internal implantation. TDR-Mk9s have been used on seals, penguins, otters, large pelagic fish, and many other applications.

User Guide/Software
