TDR-Mk9 tags are our most cost-effective archival tags. They can be used when depth, temperature and light-levels are the only sensors required by your study. Archival tags must be physically recovered to retrieve the data.
- The small size of the TDR-MK9 configurations makes this tag suitable for implantation, external attachment on small animals, or monitoring of the performance of fishing gear.
- Depth and temperature (of the tag body) are standard sensors on all models.
- A second fast-response temperature sensor is an available configuration for applications that require a minimal time-lag in registering changes in temperature external to the tag body, such as oceanographic studies.
- Light-level and a second temperature sensor can be incorporated on a sensor stalk for applications that require measurement of ambient light and temperature while the tag is implanted within the animal’s body.
- A wet/dry sensor is included in some configurations.
Below are the general physical specifications of TDR-Mk9 tags. A full description of the features is available on the downloadable TDR-Mk9 Product Features (PDF). Visit our Back/Head mount and Surgical Implant Configuration sections for the specifications of the various models.
|Attachment type||Surgically-implanted or externally mounted***|
|Sensors||Depth, Temperature and Light-level ***|
|Depth sensor range||0-200m, 0-1700m, 0-2000m ***|
|Depth sensor resolution||0.5 m|
|Depth sensor accuracy||+/- 1% of reading|
|Temperature sensor range||-40 to 60°C|
|Temperature sensor resolution||0.05°C|
|Temperature sensor accuracy||+/- 0.1°C|
|Light sensor (when installed)||5 x 10-12W.cm-2 to 5 x 10-2W.cm-2|
|Pressure rating (m)||***|
|Operating temperature rating (°C)||-20 to 50°C|
|Recommended storage temperature range (°C)||5 to -20°C|
|Maximum deployment length||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.|
*** indicates the specification is dependent upon the configuration model
The Mk9-TDR provides a time-series of readings from each sensor.
A full suite of data products are easily constructed from the sampled data using our WC-DAP program. These data products are compatible with the data products that are transmitted by our Pop-up and SPLASH tags.
- Tracking Data: Light-based Geolocation
- Diving Behavior: Dive-Duration Histograms, Dive-Max-Depth Histograms, Dive-Profile Log, Time-at-Depth Histograms
- Haulout Behavior: 20-Minute Timeline, %-Dry Timeline, Dry-Deep-Neither Timeline
- Temperature Profiles: Profile of Depth and Temp (PDT), Time-Series Temperature, Time-at-Temperature Histograms
TDR-Mk9 User Guide
Detailed description of the features of the TDR-Mk9. Includes instructions on how to use the Mk9Host program to set up and deploy TDR-Mk9 tags.
USB-Blue Driver Version: 8.00.50727 15-Jan-2009
Driver for the Wildlife Computers USB-Blue communications cable.
Mk9Host (Wildlife Computers Mk9 Host Program) Version: 1.09.1028 16-Apr-2010
Installs the Mk9Host program which is used to communicate with TDR-Mk9 tags. Mk9Host allows you to set up the tag’s deployment parameters. It also allows you to download archived data when the tag is recovered.
WC-DAP (Wildlife Computers Data Analysis Programs) Version: 3.0.369.0 05-Jan-2016
An integrated suite of programs to decode and visualize tag data downloaded from Argos and recovered tags. Also processes Fastloc® GPS and light-based geolocation data to calculate latitude and longitude estimates.
WC-GPE2 (Wildlife Computers Global Position Estimator) Version: 2.00.0027 11-Apr-2014
Produces light-based geolocation latitude and longitude estimates. Although this program is integrated with WC-DAP it must be installed separately.
