Acoustic sensors enable efficient and non-invasive monitoring of a wide range of species, including many that are difficult to monitor in other ways. Although they were initially limited in application scope largely due to cost and hardware constraints, the development of low-cost, open-source models like the Audiomoth in recent years has increased access immensely and opened up new avenues of research. For example, some teams are using them to identify illicit human activities through the detection of associated sounds, like gunshots, vehicles, or chainsaws (e.g. OpenEars).
With this relatively novel dimension of wildlife monitoring rapidly advancing in both marine and terrestrial systems, it is crucial that we identify and share information about the utility and constraints of these sensors to inform efforts. A recent study identified advancements in hardware and machine learning applications, as well as early development of acoustic biodiversity indicators, as factors facilitating progress in the field. In terms of limitations, the authors highlight insufficient reference sound libraries, a lack of open-source audio processing tools, and a need for standardization of survey and analysis protocols. They also stress the importance of collaboration in moving forward, which is precisely what this group will aim to facilitate.

Global shortage of Raspberry Pis - What are the alternatives

UPDATE: The Banana Pi didnt work out for us as it was not possible to track back all the components and ensure that they were responsibly sourced. The Rock board did work for us and we were able to port our system onto this. We will be rolling out units using this over the summer. It also looks like Raspberry Pis are coming back on line and we were able to secure a bulk order for deliver mid-summer

Hi Adam!
I mostly live within the ecoacoustics space so I'll just speak on the hydrophone part of your request; Arbimon is a free web/cloud-based platform with unlimited storage for audio files. We've got an uploader app as well for mass-uploading lots of files. There's also a bunch of spectrogram visualization/annotation tools and analysis workflows available. It's AWS running under the hood.
I have some experience working directly with AWS & Microsoft Azure, and I've found personally that AWS was more user-friendly and intuitive for the (fairly simplistic) kinds of tasks I've done.

Cleaning audiomoth circuit board
17 January 2023 11:42am
28 January 2023 5:40am
I'd also add that if the boards are just dirty or dusty, you can just remove all batteries, then wash with a toothbrush and water. Air dry (or use compressed air which speeds things up greatly) and then spot clean areas that need solvent with isopropanol as Harold mentioned. Also if you don't have access to conformal coating, you can also use a non-conductive clear lacquer. The conformal coating covers all the components and prevents short circuits due to conductive water (ie: salt water) or other contaminants. However if you do use a conformal coating, make sure all cables are connected first and the device is in the exact state that it will be deployed in. Also don't conformal coat the battery connectors since you'll want to change out batteries periodically.
2 February 2023 8:13am
Hi Akiba,
thanks for your this great advice! I used the conformal coating on parts
of the PCB with exposed metal but was has hesitent using it on the "backside" with
all the resistors and transistors. Also what about the "back" of the microfon. Might this side be coated?
Do you have any experience with coatings @alex_rogers
Greetings,
Robin

Hi!
I am not aware of any such connected loggers/recorders but they would be nice.
The AudioMoths have been revolutionary in providing audologging at a low cost but they take a lot of "data muling" (carrying SD cards in and out of the field sites) and swapping of batteries.
Cheers,
2 February 2023 7:50pm
Hi Lars, thanks for the response. We are using lots of Song Meter Micro's atm and they have proved to be resilient. Just need something which doesn't involve going on site regularly - but get the data off.
3 February 2023 7:04pm
Rainforest Connection's (RFCx) Guardian devices may be of interest. They are solar-powered and have connectivity options for Wifi, GSM and satellite transfer. They've previously been used for detecting e.g., gunshots or chainsaws (using edge computing) and then sending positive detections/alerts to folks on the ground. RFCx also hosts Arbimon, a free, no-code software platform that facilitates analysis of audio data as well. Happy to chat more if you'd like to talk further about it!

Potential collaboration: integrating acoustics and NASA airborne remote sensing to monitor animal and habitat biodiversity
30 November 2022 1:17am
10 December 2022 6:18am
Although not a professor, I know a fair number through long-term association with scgis.org, and personally am using Audiomoths in collaboration with the UC System at the Blue Oak Reserve.
Blue Oak Ranch Reserve
Blue Oak Ranch Reserve (BORR) lies within the Upper Sonoran Life Zone. Approximately two-thirds of the site is drained by tributaries of Arroyo Aguague, itself a tributary of Coyote Creek (via Penitencia Creek), which flows into southern San Francisco Bay.
I've developed a fair bit of scripts to automatically crunch things using 'Birdnet', as per:
GitHub - birdnet-team/BirdNET-Analyzer: BirdNET analyzer for scientific audio data processing.
BirdNET analyzer for scientific audio data processing. - birdnet-team/BirdNET-Analyzer
I can certainly facilitate dialogue with the Cornell Ornithology lab if you do not have those connections already.
My own background is in remote sensing (SAR, etc) and currently working in machine learning (albeit for health care currently..) this project sounds fascinating!
Are you already working with Audubon, and/or people in the UC System?
10 December 2022 6:22am
I'll also note that I'm planning to work with a few parks in the DRC/Congo basin to deploy Audiomoths alongside their camera traps.
13 January 2023 12:24pm
Dear Antonio,
It is a long-shot, but this may be relevant to what you are looking for? I have collected across 4 seasons (2022) 8-10 days/season acoustic data from 11 stations located at pine forests of different post-fire regeneration stage (>20 years since last burn, burnt in 2001, 2009, 2018) in Greece. These are typical Mediterranean forest pine landscapes - but certainly not in California or South Africa. We did not have plans at present to continue collecting data - since we got all seasons of one year, but may be the existing data or future data from these or similar areas here in Greece would be relevant to what you wish to accomplish with the airborne measurements?
Feel free to drop me a line.
All the best,
Christos
