WILDLIFE mrPAT Small Fisheries Independent Argos Location Reporter
This user guide will give you all the essential information needed for interacting with, and deploying a Wildlife Computers Mark Report PAT
About the Mark Report PAT (mrPAT)
The mrPAT is a small, fisheries-independent Argos location reporter. An animal is tagged at a known time and location. At some user-defined time interval, or absolute date, the release pin is activated causing the tag to separate from its tether. Being positively buoyant, the tag floats to the surface and Argos transmissions are initiated once a dry environment is recognized. The first Argos location marks the last known location of the tagged animal.
Before you Begin
The list below shows what is required to configure and deploy the mrPAT:
- A Wildlife Computers online portal account
- A Windows computer with Tag Agent Software and USB driver installed
- A Wildlife Computers communications cable
- A magnet
Visit wildlifecomputers.com to download the required software (Tag Agent and
the USB-Blue Driver) and setup an account. At the end of this document, there
is a list of key terms and concepts for reference. We recommend new users
review this list.
Anatomy of a Tag
Wet/Dry Sensor
The wet/dry sensor is composed of two elements; a small metal post at the top
of tag and metal strap on the side of tag.
The wet/dry sensors should never be covered in any way. This includes anti-
fouling substances and attachment adhesives (e.g. epoxy). Covering can
interfere with the tag’s ability to differentiate between wet and dry
conditions.
Contact Wildlife Computers if tags are to be used in brackish or freshwater.
Special wet/dry sensor hardware may be necessary depending on water
conductivity.
Communications Port
The communications port is where the Wildlife Computers Communications Cable
connects to the tag. Prior to a deployment, this port should be sealed with
the plug provided. Smear a small amount of the silicone grease supplied onto
the sides and bottom of the plug, align the plug and pins, and carefully push
the plug into the port. If it does not align easily with the pins, rotate it
180° and try again. The plug prevents corrosion of the pins during the
deployment; however, the plug is not required for the tag to function
normally.
LED Indicator Light
The LED indicator light displays what mode the tag is in.
Release Pin
The tag begins its release sequence by energizing the release pin causing an
electrolytic reaction. In sea water, it takes about 4 hours for the pin to
erode to a point where the tag separates from the tether.
Antenna and Float
The mrPAT is designed to float with the antenna and wet/dry sensor above the
water surface. It is of great importance that the full package (with tether
and anchor attached) is positively buoyant. If attachment fails and the anchor
pulls out of the animal, the tag will only report if a dry environment is
detected. If the tag sinks, it may be crushed or sit on the bottom until the
release date/mission duration is achieved.
Interacting with a Tag
Tag Agent Software is used to communicate with the mrPAT. Tag Agent and the
USB-Blue Driver can be downloaded from our website:
wildlifecomputers.com. Once installed, Tag
Agent can be used to:
• Configure the tag deployment duration or release date
• Change tag states
• Upload remotely-selected settings into a tag
• Check sensor readings and conduct test transmissions
To communicate with a tag, open Tag Agent Software (Figure 2).
Use the USB communications cable to plug the tag into your PC. Take care to ensure that the pins are aligned. Once plugged in, swipe a magnet near the tag communication port to establish connection. The tag LED at the base of the antenna will turn orange, and the Tag Agent home screen will appear with tag information on the left and sensor readings on the right (Figure 3).
If the tag is new or was previously programmed by another user, a pop-up box will appear asking if you wish to take ownership of the tag. Becoming a tag administrator gives you the authority to select and save new settings.
Configuring Deployment Duration
To set the tag deployment duration or release date within Tag Agent, select the Administer Tag button in the upper menu.
A new window will open up revealing two sections: Tag Information and Tag Release Sequence.
Tag Information
All information about the tag type, serial number, tagware version, and Argos
settings can be found under the Tag Information tab. The Tag Name field is an
optional user-definable label.
Tag Release Sequence
The mrPAT can be programmed to begin its release sequence either after a specified deployment duration (interval), or on a specific calendar date.
- When an interval duration (day) is selected: release is initiated at the same time of day when deployment was detected. For example, a deployment scheduled for five days starting on 1 May 2017 at 18:00 UTC will initiate its release sequence on 6 May 2017 at 17:59 UTC, five days from deployment.
- When a specific calendar date is selected: release is initiated at midnight UTC rollover into the release date, regardless of the time of day the deployment was detected. For example, a deployment on 1 May 2017 at 18:00 UTC with a release date of 6 May 2017, will initiate its release sequence on 6 May 2017 at 00:00 UTC, four days and six hours from deployment.
Once release is initiated, the release link begins to degrade. After approximately 4 hours, the nose cone will separate from the body of the tag. The tag will ascend to the surface and Argos uplinks will begin.
Conditional Release
The mrPAT monitors for premature tag detachment. The default settings will
trigger release if the tag is more than five percent dry for two consecutive
hours with the wet/dry sensor sampled every three seconds. The standard
release settings are appropriate for pelagic fish that don’t often surface.
You can choose to create custom settings and adjust the conditions that will
trigger release.
Premature release detection is a critical feature of the mrPAT. Prompt
reporting on release ensures you get the last known location of your animal,
even if the tag is shed before the scheduled release date. Disabling
conditional release is not recommended unless animals are expected to venture
into fresh water.
Send Changes Button
Once release settings have been chosen, use the blue Send Changes button to
load settings into tag. Tag Agent will confirm receipt of settings via dialog
box. The Check for Updates tab on the top left navigation bar of Tag Agent
home screen can be used at any time to see if setting updates are available.
Tag States: Auto Start, Start, and Stop Modes
The mrPAT has 3 states: Auto Start, Start, and Stop (Figure 5).
- Auto Start puts the tag in standby. A tag in auto-start mode can be activated by sea water submersion or by magnet swipe protocol.
- Start mode activates the tag. In Start, data collection is running and the tag begins monitoring for its set release condition. The mrPAT can only be started by submersion in salt water or by magnet protocol. Tag Agent cannot be used to activate the mrPAT.
- Stop puts the tag into deep shutdown for storage. The tag will remain unresponsive unless connected to Tag Agent.
LED Blink Patterns
Passing a magnet near the communications port will cause the tag to blink the
indicator light. The blink pattern reveals the tag state:
- Auto Start: Two blinks and a pause repeated 3 times
- Start: Ten rapid blinks
- Stop: No blinks
Changing Tag States with a Magnet
Passing a magnet near the communications port can toggle the tag between Auto
Start and Start mode. After a magnet is swiped and the blink pattern is
displayed, the indicator light remains on for two full seconds. If the magnet
is swiped again during the window that the light is on, the mode will change
and the blink pattern of the new mode will display. Once the tag begins
release, you can no longer change modes with a magnet. You must change modes
by connecting to Tag Agent.
If you start a tag, and are using the default premature release settings, the
tag must be deployed in water within two hours or premature release will
begin.
Figure 7—Magnet and indicator light sequence to switch from Auto Start to Start. A magnet swipe near the communications port, will double-blink three times. Then the indicator light will remain on for two seconds. Swiping the magnet again in the window while the light is on will put the tag in Start mode. The tag will blink 10 times rapidly and then remain lit for two seconds to show it is activated.
Note: If a tag is deployed by mistake, either the magnet swipe protocol or Tag Agent can be used to set the active tag back to Auto Start.
Disconnect from the mrPAT
Use the Disconnect Tag tab on the upper left of the Tag Agent Menu to select
the tag state before unplugging. If you are planning to deploy in the near
future, select Auto Start mode. The tag will then auto-deploy on saltwater
submersion.
Always disconnect the tag using the Disconnect Tag button. Unplugging without setting the tag state could leave the tag in a mode that will rapidly deplete the battery.
Checking Sensor Readings and Transmission Test
The sensor values displayed on the Tag Agent home screen are continuously
updated from the tag. Sensor functionality can be validated by manipulating
the sensors as follows:
Temperature—when you first plug into the tag, the temperature will read
approximately room temperature. You can expect the value to increase over time
as the LED heats the sensor.
Wet/Dry—connecting a wire from the large rectangular ground plate strap to the
small metal post at the top of tag will change the value from over 200 to less
than 20.
Tilt—changes with tag orientation.
Test Transmission
Under the Advanced button on the top menu, there is an option to Send Test
Transmission. When
selected, a pop-up box will appear displaying the transmit voltage. The
transmission voltage should read approximately 2.5-3.0v.
Argos Transmitter Test
The Argos Transmitter test allows for a full system test to confirm that the
tag is successfully sending messages to the Argos satellites. Click on the
Advanced Tab then Argos Transmitter Test.
- Seconds Offset: If you will be testing multiple tags at one time, you can use this parameter to offset transmissions so the tags will not transmit at the same time.
- Transmit Count: How many times you want the tag to transmit. 120 transmissions at a 90 second interval will provide a 3-hour test, which is usually enough to coincide with a couple of satellite passes. Check the satellite passes in your area prior to beginning the test.
- Seconds Apart: The time between each transmission. The usual repetition rate for a mrPAT is 90 seconds.
When all of the tags are setup and deployed, take them outside where they have
a full view of the sky. For best results, float the mrPATs in a bucket of
saltwater.
When the test ends, the tag will automatically go into Stop Mode. You will
need to connect to the tag again with Tag Agent to put it into Standby Mode
prior to deployment.
Upon completion of the Argos Transmitter Test, the tag will be in STOP mode
and you will need to communicate with it again prior to deploying it.
Set Tag Time
Under the Advanced button on the top menu, there is an option to Set Tag Time.
If the tag clock is not set when you first communicate with a tag, Tag Agent
will ask if you want to set the clock. If there is any other time that you
wish to confirm that the clock is set, you can choose this Set Tag Time
option.
Apply Script and Console
These two options under the Advanced Menu in Tag Agent are for troubleshooting
with Wildlife Computers Support. You will not need to use these options under
normal circumstances.
Using Tag Portal to Select Settings Remotely
Tag Portal is the cloud-based service offered by Wildlife Computers for
remotely selecting tag settings.
When logged into your Portal account, a list of the tags which you have administrator power over can be viewed under the “My Tags” tab. To select settings, click on the serial number of the tag you wish to configure or use the pencil icon.
This will open a new window with setting selections. The same programming
options are available whether settings are configured via Tag Portal or from
within Tag Agent.
Once settings have been selected in Tag Portal, click the blue Propose
Changes. This will save the settings in the cloud. The next time that tag
communicates with Tag Agent (no matter who plugs the tag in), a dialog box
will appear notifying you that new settings are awaiting upload.
Multiple set-ups can be published resulting in a queue of configurations
awaiting upload. In this case, a dialog box will reveal a list of the
configurations published, when they were selected, and which administrator
chose the settings.
Tag Portal maintains a historic record of tag settings each time changes are
uploaded into a tag. The record is instantly updated so long as an Internet
connection is available.
Offline Mode
Before programming can be done offline, Tag Agent must be downloaded and
opened with valid credentials entered while connected to the Internet.
So long as the software has been opened once and credentials have been
entered, programming offline is feasible. To program the release date or
mission duration, select Administer Tag from Tag Agent’s top navigation bar,
choose Settings, and click Send Changes. A dialog box will confirm settings
have been loaded into tag.
The next time Internet connection is established, and Tag Agent software is
open, the historical record will be updated in Tag Portal.
Online templates are not accessible when working offline. To program a group
of tags with the same settings when working without an Internet connection
create a local template. A file of the selected tag settings will be saved
onto your local machine. Local templates can be created and applied in the
Template Manager. Expose the Template Manager with the icon in the upper right
corner of the screen.
The Internet connection status is displayed at the bottom of the Tag Agent
home screen.
Sync Argos PTT Numbers to your Portal Account
Wildlife Computers supplies the Argos PTT numbers for all mrPAT tags. These
PTT numbers must be synced to your portal account to view data.
Before tags are shipped, Wildlife Computers will contact you with Argos sub-
program login credentials. To link these credentials to your Portal account:
- Log in to your portal account
- Click on the account holder’s name in the top-right menu bar
- Select Account Settings
- Select the Add Account tab and enter the provided username and password. Once your Argos sub-program is synced, all incoming data will be automatically ingested into the portal
Transmitted Data
Transmitted data helps infer if the tag was still attached to a swimming fish
at the time of release.
- Daily Temperature Range: Min and Max values for each GMT day for the last 100 days of deployment
- Status Message: Current temperature at the time of transmission
Email Alerts
Within the Data Portal, alerts can be set to email you when tags begin
transmitting. On the Data Portal home page, select Data Alerts from the left
sidebar menu.
Click New Alert. Select the PTT ID numbers and specify the destination email
address and alert start/stop times. When complete, click Save.
Tag Storage and Battery Maintenance
Proper tag storage is important to minimize passivation and keep the batteries charged. When stored correctly, the amount of battery life lost per year is only 1-2 percent.
mrPAT Storage—Less Than One Month
Not much needs to be done as you will be deploying them soon. Wildlife
Computers recommends storing tags in a cool, dry environment—ideally around
+5° C.
mrPAT Storage—Longer Than One Month
If you will be storing mrPAT tags longer that one month, you will need to
place your tag in “Stop” mode using Tag Agent and exercise the batteries every
3 months.
Connect to each tag and login to Tag Agent. In the menu at the top, you will
see the “Disconnect Tag” tab. Scroll down to “Stop.” The tags can now be
stored. Wildlife Computers recommends storing tags in a cool, dry
environment—ideally around +5° C.
Once tags are stored, they must be “exercised” by sending test transmissions in Tag Agent. Connect to each MiniPAT and log into Tag Agent. In the menu at the top, you will see the “Advanced” tab. Scroll to select, “Send Test Transmission.”
The test transmission voltage should read approximately 2.5-3.0v and the
battery voltage displayed on the main sensor screen should be around 3.2v.
If you receive a low voltage reading, it may be due to passivation forming
during storage. We recommend repeating this test at least 3-10 times to
dislodge the possible passivation layer. If you continue to receive a low
voltage reading, anything less than 3.2v, contact your technical sales
consultant.

Antifouling Tags
Heavily fouled tags can be hugely detrimental to tagging studies as fouling
growth over critical sensors can impede the tag’s transmitting performance.
Especially for deployments in tropical waters, it is imperative that tags be
protected against marine growth. Wildlife Computers endorses two antifouling
paints, Micron and Propspeed. While we prefer Micron66, it is not available in
some countries. There are dozens of paint options available, but Micron 66,
Micron77 and Micron99 are our favorites from years of testing and client
feedback. Micron66 is a copper-based antifouling paint that has a biocide
which repels barnacles. For optimal protection, it is critical to use
International Paints’ Interprotect primer in addition to several coats of
paint. Micron66 is a great choice for slow movers like sea turtles and whale
sharks—http://bit.ly/Micron66
Propspeed is non-toxic and widely available. Its glossy texture sloughs off marine growth before it has a chance to bond. Constant water flow is key to Propspeed’s effectiveness making it most beneficial for active swimmers. Wildlife Computers offers an optional service to sand, mask, and paint tags with Propspeed antifouling and coat the wet/dry sensors with conductive polymer. This comprehensive antifouling service is offered at a charge of $100 per tag prior to shipping. We do not apply Micron antifouling paint due to the hazardous nature of the product.
Tips and Tricks When Antifouling Your Tags
Here are a few critical points to ensure successful tag antifouling:
- Mix the Micron paint with a battery drill and paint mixer tool—this step is imperative to dislodge the copper off the bottom of the can! If you can’t use a drill, mix it thoroughly with a wide paddle to ensure all the copper sludge is mixed into the paint.
- After covering the wet/dry sensors, communications port, depth sensor opening, “Battery Isolator” screw, and LED viewing port with tape, prime the entire tag including all the antennas when applicable—Fastloc® GPS patch antennas, Fastloc® GPS whip antenna, and the Argos antenna.
- Only prime two to three tags at a time and ensure that the first coat of Micron paint goes on when the primer is tacky and not dry (if too late, apply another coat of primer and then paint when tacky).
- Apply three to four coats of Micron, allowing time to dry between coats (it is ablative, so it needs several coats that will wear off over time in the water).
- Remove masking tape!
- Optionally, apply another coat to the Fastloc® GPS and Argos whip antennas after attaching the tag (especially to a turtle). Remember to avoid the wet/dry sensors. Micron will not harm the attachment epoxy.
Check out our antifouling resources on the Wildlife Computers website including a video that shows you exactly how to do apply antifouling paint.
