Data management and processing tools / Feed

Conservation tech work doesn't stop after data is collected in the field. Equally as important to success is navigating data management and processing tools. For the many community members who deal with enormous datasets, this group will be an invaluable resource to trade advice, discuss workflows and tools, and share what works for you.

Hi @emmahiggins

sounds like a great plan. 

Could you tell more about the content of the program, and perhaps the institutional context (which department(s) is(are) going to offer the course, and which research programs or projects are related to it) , so we'll have something to orient our thoughts?

Drop-deployed HydroMoth

Hi all, I'm looking to deploy a HydroMoth, on a drop-deployed frame, from a stationary USV, alongside a suite of marine chemical sensors, to add biodiversity collection to our...

Hi Matthew,

Thanks for your advice, this is really helpful!

I'm planning to use it in a seagrass meadow survey for a series of ~20 drops/sites to around 30 m, recording for around 10 minutes each time, in Cornwall, UK.

At this stage I reckon we won't exceed 30 m, but based on your advice, I think this sounds like not the best setup for the surveys we want to try.

We will try the Aquarian H1a, attached to the Zoom H1e unit, through a PVC case. This is what Aquarian recommended to me when I contacted them too.

Thanks for the advice, to be honest the software component is what I was most interested in when it came to the AudioMoth- is there any other open source software you would recommend for this?

Best wishes,


Hey Sol, 

No problem at all. Depending on your configuration, the Audiomoth software would have to work on a PCB with an ESP32 chip which is the unit on the audiomoth/hydromoth, so you would have to make a PCB centered around this chip. You could mimic the functionality of the audiomoth software on another chip, like on a raspberry pi with python's pyaudio library for example. The problem you would have is that the H1A requires phantom power, so it's not plug and play. I'm not too aware with the H1e, but maybe you can control the microphone through the recorder that is programmable through activations by the RPi (not that this is the most efficient MCU for this application, but it is user friendly). A simpler solution might be to just record continuously and play a sound or take notes of when your 10 min deployment starts. I think it should last you >6 hours with a set of lithium energizer batteries. You may want to think about putting a penetrator on the PVC housing for a push button or switch to start when you deploy. They make a few waterproof options. 

Just somethign else that occured to me, but if you're dropping these systems, you'll want to ensure that the system isn't wobbling in the seagrass as that will probably be all you will hear on the recordings, especially if you plan to deploy shallower. For my studies in Curacao, we aim to be 5lbs negative, but this all depends on your current and surface action. You might also want to think about the time of day you're recording biodiversity in general. I may suggest recording the site for a bit (a couple days or a week) prior to your study to see what you should account for (e.g. tide flow/current/anthropogenic disturbance) and determine diel patterning of vocalizations you are aiming to collect if subsampling at 10 minutes. 



Hi Sol,

If the maximum depth is 30m, it would be worth experimenting with HydroMoth in this application especially if the deployment time is short. As Matt says, the air-filed case means it is not possible to accurately calibrate the signal strength due to the directionality of the response. For some applications, this doesn't matter. For others, it may.

Another option for longer/deeper deployments would be an Aquarian H2D hydrophone which will plug directly into AudioMoth Dev or AudioMoth 1.2 (with the 3.5mm jack added). You can then use any appropriately sized battery pack.

If you also connect a magnetic switch, as per the GPS board, you can stop and start recording from outside the housing with the standard firmware.

Newt belly pattern for picture-matching

Hi!We are investigating the ability to use belly pattern of Great crested newts (Triturus cristatus) at larval stage for picture-matching in capture-recapture studies. Do...

Cool project! (I would definitely match with the second photo on your example). Might be a project that you can run on Zooniverse instead of a Google Form?

Hi Robin this is a great idea! Have been thinking about approaching the community for quiz questions. Will reach out to Xavier to ask if we can use it or if he wishes to run it on next Wednesdays VH

Thanks, and that's a match! 

All these pictures are from a lab experiment and formated with AmphIdent. We took weekly belly pictures of several larvae. The aim of this google form is to validate (by comparing answers with the lab reference image base) picture-matching by human is reliable although the change of pattern can be verry quick at this life stage.  

If validated there will be the need to improve existing pattern-matching solutions for in situ observations of larvae, for instance with ML and/or Human Learning (thanks Zooniverse)...

Camera Trap storage and analyzing tools

Hello everyone I am a current Peace Corps volunteer in Paraguay and am working with a local national park to create a camera trap project. A large part of the project is focused...

I don't have an easy solution or a specific recommendation, but I try to track all the systems that do at least one of those things here:

That's a list of camera trap analysis / data management systems that use AI in some way, but in practice, just about every system available now uses AI in some way, so it's a de facto list of tools you might want to at least browse.

AFAIK there are very few tools that are all of (1) a data management system, (2) an image review platform, and (3) an offline tool.  If "no Internet access" still allows for access to a local network (e.g. WiFi within the ranger station), Camelot is a good starting point; it's designed to have an image database running on a local network.  TRAPPER has a lot of the same properties, and @ptynecki (who works on TRAPPER) is active here on WILDLABS.

Ease of use is in the eye of the beholder, but I think what you'll find is that any system that has to actually deal with shared storage will require IT expertise to configure, but systems like Camelot and TRAPPER should be very easy to use from the perspective of the typical users who are storing and reviewing images every day.

Let us know what you decide!

Can't beat Dan's list! 

I would just add that if you're interested in broader protected area management, platforms like EarthRanger and SMART are amazing, and can integrate with camera-trapping (amongst other) platforms.

Ha - you're already in my thread, i've got your project in there, don't worry! 

But it's more I don't want proof of concept early R&D type projects that are just destined for a paper or a hobby project, I want to hear about projects that have some plan for usability and scaling so that other people can take and implement them. 

I think that my system is likely the closest thing you will find in terms of production ready and potential to scale as it once was a commercial system with complete over the air updates more than 10 years ago. It’s been in use by many people for more than 10 years and has used AI triggering since 2019. I’m pretty sure no other system can claim that.

So I have the system but you got me on the scalability because to do that you need funding. I don’t have the funding. If I had the funding I’d be doing it full time. But I’ve said enough now. So I’ll leave it at that.

This thread is off-topic in this conversation, so happy to continue it in the other one. However, just noting - your system is one example, but not the only one - there are certainly other early warning systems in varying stages of development, testing and roll out, and using different levels of technology (ai or otherwise).
