Wildlife tracking technologies have already massively advanced our understanding of the natural world, from uncovering previously mysterious migration patterns and key movement corridors to demonstrating the impacts of anthropogenic pressures and climate change. Recent advances in the development of technologies for collecting and transmitting biologging data have unlocked the potential for fine-scale data collection at a near-global scale, which when integrated with remotely sensed environmental data offers an unprecedented biological lens into ecosystem health and environmental change (Jetz et al. 2022).
New technologies on the horizon include small satellites like CubeSats, which are being investigated by NASA, the ICARUS Initiative's satellite system, and a variety of other ventures aiming to improve the coverage, accuracy, and capacity of wildlife tracking data collection. Combined with the increased availability of high-resolution environmental data and analytical developments in movement modeling, these advancements are empowering movement ecologists to ask previously unanswerable or unimaginable questions. It’s clear that this discipline sits at the precipice of major breakthroughs that could revolutionize our understanding of animal movement and the natural world.

Fully-retrievable Satellite Tags for Seals?
10 April 2024 4:49pm
7 May 2024 4:04pm
Honestly, no (at least not for wildlife applications).
I suspect for the manufacturing community it's a balancing act, and I am not confident that the manufacturing community has invested a lot of resources or effort to integrate sustainability in their tag designs specifically related to the materials. Reasons that come to mind are material durability and cost (both materials costs and cost to for R&D).
With that said, I think Stuart (below) makes a good suggestion...
14 May 2024 11:26am
We are ready to make efforts on materials, but today there are few solutions available. Today, our partners' R&D efforts are focused on renewable energies and the energy source's capacity. In the absence others solutions, and to take action, we have chosen to develop solutions to recover these tags, some of which are reusable (thanks to Gonio RXG-234 @ThomasGray). To date, thousands of tags have been recovered and some reused. This is the "upcycling" of science! It's a small step, but a great leap forward!

Acoustically Transparent Epoxy
26 April 2024 3:26pm
1 May 2024 5:35pm
Same issues here. A MEMS is a great idea to pot, but you really need a piezoelectric element for this to work and not a MEMS based on capacitance (btw they're all capacitance, except for one now discontinued...). It was originally made by Vesper, but the company was bought out last year and the MEMS is no longer made.
This is because you're no longer really doing a typical microphone, this would be a contact type hydrophone. For waterproofing, you can actually get a waterproof MEMS. As long as your not submerging this for an extended period, it should do the job. Be sure to keep the cable short between the PCB and the mic as you'll get noise as I've experienced.
For generally answering your question on the "best" epoxy to with sound transparency, in general the harder the material the lower the acoustic impedance. I use Epotec 301 resin with a hardness of 85. Your shape will also influence the resonance frequencies, meaning the flat frequency response will now be distorted and you'll probably have distorted audio. .
3 May 2024 1:25am
You generally don't want to pot MEMS microphones since they're designed to pick up on air pressure changes and adding any material in front of the microphone just introduces another transition layer where pressure waves need to propagate through. Also, potting the MEMS microphone can be tricky since if you get any material in the port, you could damage the microphone or drastically reduce its performance. If you want to seal something with epoxy, take a look at contact microphones. Higher frequencies will be attenuated but depending on the application, it could work.
There are companies, however, that design fabrics that are waterproof/resistant but have a relatively low acoustic impedance. SAATI has a variety of samples that you can request and GORE makes Acoustic Vents that could work. You can design a mechanical housing around your MEMS microphone with small perforations that are covered by one of these materials. I did this for one of my latest projects and it holds up just fine in heavy rain conditions.
3 May 2024 5:34pm
Hi Jesse,
For a material to be acoustically transparent (in air), the speed of sound in the material times its density must match that of air. Realistically, any solid material will have a greater density than air, and a higher speed of sound to boot, so I'm afraid there's no way to match it to air. Sorry.

Waterproofing DIY VHF transmitter
27 March 2024 8:57am
21 April 2024 9:27am
That's my kinda crazy @Rob_Appleby. Reminds my of a concept from my last job where they were trying to create strain gauge power meters that customers could self apply to their bikes. Normally this process was done in factory using special CA glue cured in 50-90c ovens. For the self applying version they were experimenting with an adhesive that had tiny metal beads in it that would heat up when a current was applied to self cure if I remember correctly.
22 April 2024 2:44pm
Now I want to be able to drop it from a drone and have it glue itself to the fur of a deer or wild hog. I am designing that now, it will have a detachable lawn dart that drops from a drone and lands on a target animal. That lawn dart delivers the payload, either a tracker or a dose of contraceptives. Then the drone comes and picks up the lawn dart again for reloading.
So the lawn dart has a small compressed air cylinder and some pneumatic style switches. When it touches down the switch actuates and the compressed air energy is used to deliver a dose of drugs and or spray some glue and ink. That can be reloaded with a bike pump and hypodermic.
22 April 2024 2:51pm
I am working on that too haha. So in my design you load the glue gun with two part Loctite, it has two separate metal rings. Glue and hardener in each ring. Then each ring has a few tiny holes drilled, and you fill the holes with a disposable plug.
When the switch is actuated the pressure inside the metals rings goes from atm to 100kPa, and sprays the glue and hardener together as the plugs blow out. The transmitter is attached to the plugs, so it is left behind and glued in place with one switch. That loctite glue is basically instant. The whole thing would not even be that traumatic to the animal. When you score a hit, you find the lawn dart glue gun again and pick it up with the drone.

Thanks @Freaklabs, I think you'll really enjoy getting involved with this too as we're looking for input from makers in the community to get the most from the approach and to capture features and usability ideas from a large number of people.
I've a new modular drop-off tag build using @Rob_Appleby's original SensorDrop board that I think would be great for this project too to see if we can drop different compartments, or do various different timed events with the one TimeLord board.
Most importantly, we have to make it play a MIDI version of the DoctorWho theme song when you arm the device. That has to be the #1 feature if you ask me!

non-invasive technique to apply GPS collars without catching?
14 June 2021 12:01pm
2 April 2024 7:18pm
Not sure what happened to the excerpt I wanted to post. Apperently the Alaska study authors had some scepticism themselves.
I would be extremely worried about catching wrong species in many cases - with potentially detrimental effects.
12 April 2024 2:17pm
My study in particular is only looking at species that go under fence holes in Southern Africa. The hole determines species size and juveniles for these species are so small the collar would just fall off. I think a proper study could really determine these collars could be useful if the right study species and setting location was determined.

DIY VHF receivers?
12 March 2024 2:51pm
29 March 2024 4:32pm
Hi Brandon,
I agree and think VHF will always have better range than UHF. Given how commonly it's used in wildlife tracking, it also makes perfect sense to use it if possible. The trade-off for us was to go for lower cost and higher availability parts. This is particularly a problem for VHF receivers, as you mentioned in your original message. But, SDR is good option potentially for VHF (and UHF), especially given the success of MOTUS.
Range of our 433MHz UHF tags was usually around 250m (up to 500m) LOS, using an external antenna and a high transmission power. We also used high gain, omnidriectional antennas on the receiver end. Tags were triggered by an accelerometer threshold so that they'd save a bit of power whilst animals were resting.
More than happy to discuss further and help if I can.
Cheers,
Rob
3 April 2024 5:04am
Hi Brandon,
This is hard for me to write, because I don't have good news for you. You can find many receivers and transmitters for 433MHz that are used for remote control, such as wireless doorbells, garage door openers, lost model locators, etc. These are extremely cheap, a couple of dollars literally. While this tech can be modified to operate with wildlife tags (around 150MHz), we are talking about hacking RF, not to be approached lightly.
If you really need to DIY, I see 2 options: migrate to 433MHz and build/rebuild all your kit (tags, collars, receivers, locators). Commercial solutions are cheap and available, the work remaining is not much above handyman level. But it is work, and not just work but also testing.
The other option is to remain with 150MHz (although you can make your own tags) and modify an aviation receiver (it lets you listen in to aircraft talking to each other or to the airport). These receivers operate at 130MHz, which puts it in spitting range of 150MHz wildlife tags (this matters). This is the option I'd go for, just because I know it can be done, and I have less sense than curiosity.
4 April 2024 9:05pm
You mention you're working with an engineer, here are a couple of pointers:
- with an SDR (the "digital USB receivers" you mention) you can scan some bandwidth to detect radio pulses. I'm only familiar with the Lotek coded VHF transmitters but they can be received as in the Motus Sensorgnomes. I can point you at the code used there, it does involve a good amount of digital signal filtering/analysis code. One issue with the SDRs is that they're pretty power hungry so you need to plan on more solar panel and battery than you may like, e.g. even rPi Zero + SDR is probably >300mA. Another issue can be interference in that SDRs have a very wideband front-end and so TV, radio, and other stuff can desensitize the front-end.
- there are integrated receivers (ICs) that can be tuned to 150Mhz and can detect VHF transmissions, it's easy for non-coded ones, a bit more involved for coded ones. Specifically, the Semtech sx1231 or sx1276 series are widely available (often called Hope RF69 or RF96, which are modules with those chips). You need someone comfortable writing a customized driver that uses OOK mode or RSSI detection. The other issue is that while there are many suitable boards available for 433/868/915Mhz (e.g. Adafruit, Sparkfun, LilyGo, and many others) you most likely won't find one for 150Mhz. However, for RX-only the matching isn't so super important if you have a good antenna and the signal isn't crazy weak. From a power point of view these can sip power so you can run one on an 18650 for days and a small 1W-5W solar panel is most likely all you need.
Hope this helps...

Need tips on best practices tracking turtles
4 March 2024 12:52pm
6 March 2024 1:24pm
Hi Gabriel,
Our TagRanger Tags can be used for tracking turtles, we already have a tracking project commencing soon in South America for ~40 turtles...
https://www.tagranger.com/
The Tags use LoRaWAN allowing you to communicate with your Tags in real time. As well as requesting current GPS locations from long distances away (20km Line of Sight) you can also use the integrated ranging tools which give you distance to your Tag in metres when you get closer.
Key features:
LoRaWAN (tested > 20km line of sight). Use a 'Finder' which is a handheld gateway or you can also use your own LoRaWAN network.
UWB ranging gives distance (in metres) to the Tag up to 150m away
Hybrid Ranging combines the equivalent of a VHF pinger from a few km away (line of sight) with the UWB ranging when you get closer
Log Download remotely using UWB radio
The Tag can last for very long lifetimes depending on how you configure it
Please drop me a line if you are interested in hearing more about this and how we could configure it best for your application.

Data Logger Suggestions
31 January 2024 1:42pm
10 February 2024 2:19am
Hi Andrea,
The OpenLog Artemis might be an option. I haven't used one of these yet, but its what I immediately thought of. Built in real time clock and IMU that records to microSD. It has four 14-bit ADCs and I2C connectors for the 'Qwiic' or 'grove' sensor boards. I'm not sure if it has programmable on/off cycles with the clock but you may find an existing project that does this.
SparkFun OpenLog Artemis
Description Features Documents We have stock of a new OpenLog Artemis (without IMU) available now! Notice: Supply chain constraints have made the on-board ICM-20948 IMU very difficult to source. That said, we have a new version of the OpenLog Artemis available now with the IMU removed. The SparkFun OpenLog Artemis is an open source data logger that comes preprogrammed to automatically log IMU, GPS, serial data, and various pressure, humidity, and distance sensors. All without writing a single line of code! OpenLog Artemis, or "OLA," automatically detects, configures, and logs Qwiic sensors. The OLA is specifically designed for users who just need to capture a lot of data to a CSV and get back to their larger project. Included on every OpenLog Artemis is an IMU for built-in logging of triple-axis accelerometer, gyro, and magnetometer. Whereas the original 9DOF Razor used the old MPU-9250, the OpenLog Artemis uses the latest ICM-20948 from InvenSense capable of nearly 250Hz logging of all nine axes. Simply power up the OpenLog Artemis and all incoming serial data is automatically recorded to a log file with baud rates up to 500000bps [1], supported! The OLA also has four ADC channels available on the edge of the board. Voltages up to 2V can be logged with 14-bit precision up to 1900Hz for one channel and 1000Hz logging all four channels. Additionally, based on feedback from users we've added an on-board RTC so that all data can be time stamped. The OpenLog Artemis is highly configurable over an easy to use serial interface. Simply plug in a USB-C cable and open a terminal at 115200bps. The logging output is automatically streamed to both the terminal and the microSD. Pressing any key will open the configuration menu. The OpenLog Artemis automatically scans, detects, configures, and logs various Qwiic sensors plugged into the board (No soldering! No programming!). Currently, auto-detection is supported on the following Qwiic products: Any u-Blox GPS Modules (Lat/Long, Altitude, Velocity, SIV, Time, Date) such as: ZED-F9P 1cm High Precision GPS NEO-M8P-2 2.5cm High Precision GPS SAM-M8Q 1.5m 72 Channel GPS ZOE-M8Q 1.5m Compact GPS NEO-M9N 1.5m GPS MAX-M10S 1.5m Ultra-Low Power GPS MCP9600 Thermocouple Amplifier NAU7802 Load Cell Amplifier LPS25HB Barometric Pressure Sensor BME280 Humidity and Barometric Pressure Sensor MS5637 Barometric Pressure Sensor MS5837 Depth and Pressure Sensor SDP31 Differential Pressure Sensor MS8607 Pressure Humidity Temperature Sensor MPR0025PA MicroPressure Sensor TMP117 High Precision Temperature Sensor AHT20 Humidity and Temperature Sensor SHTC3 Humidity and Temperature Sensor CCS811 Air Quality Sensor SGP30 Air Quality Sensor SGP40 Air Quality (VOC Index) Sensor SCD30 CO2 and Air Quality Sensor SN-GCJA5 Particle Sensor VEML6075 UV Sensor VCNL4040 Proximity Sensor VL53L1X LIDAR Distance Sensor ADS122C04 ADC PT100 Sensor Qwiic Mux allowing for the chaining of up to 64 unique buses! MAX30101 Pulse Oximeter and Heart Rate Sensor ISM330DHCX IMU MMC5983MA Magnetometer KX134 Accelerometer ADS1015 ADC LPS28DFW Barometer VEML7700 Ambient Light Sensor This OpenLog uses common microSD cards to record clear text, comma separated files. You probably already have a microSD card laying around but if you need any additional units see the related items below. The OpenLog Artemis supports microSD cards formatted as FAT32 as well as the older FAT16 formats up to 32GB. The OpenLog Artemis can use any size microSD card and, as of firmware version 1.11, supports exFAT cards in addition to FAT32. Very low power logging is supported. OpenLog Artemis can be configured to take readings at 500 times a second, or as slow as 1 reading every 24 hours. You choose! When there is more than 2 seconds between readings OLA will automatically power down itself and the sensors on the bus resulting in a sleep current of approximately 18uA. This means a normal 2Ah battery will enable logging for more than 4,000 days! OpenLog Artemis has built-in LiPo charging set at 450mA/hr. New features are constantly being added so we’ve released an easy to use firmware upgrade tool. No need to install Arduino or a bunch of libraries, simply open the Artemis Firmware Upload GUI, load the latest OLA firmware, and add features to OpenLog Artemis as they come out! The OLA can be tailored to many different applications and we will be releasing custom versions of the firmware which can be found on our Documents tab above. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Hi Courtney,
I haven't read through all the Wildlife computer options but I have heard of people using Zinc Anode disks as a type of slowly degrading attachment point for tags. We use these also as a backup for other types of releases on Oceanographic moorings etc. It would take some testing to see how the zinc could be attached or be small enough to degrade completely away from the pinniped but still be strong enough to hold a tag.....just some thoughts!
Cheers,
Stuart
