New paper: A novel method for identifying coded tags recorded on aquatic acoustic monitoring systems

Carly Batist

26 September 2022 2:11pm

Authors demonstrated "a low cost, simple method to support acoustic tag surveys by identifying tags both from direct acoustic recordings & by reconstructing code packets from processed C-POD data. Method was applied to decode tag detections from bass & Twaite shad."

From Alex on Twitter:

Yes. The HydroMoth has the same microphone and firmware as the standard AudioMoth which is widely used for terrestrial conservation. You would need the standard green case which has a waterproof acoustic vent.

@Andrew_Hill Out of curiosity, since this campaign reached its goal & is ending soon, is it possible to turn the remaining Hydromoth units that didn't sell into Audiomoths for a limited GroupGets? I understand that Hydromoths can be used terrestrially as well, but they are more expensive than the last Audiomoth campaigns have been by $50+ so just wanted to see if Audiomoths would still be cheaper. Just trying to figure out if I should buy more Hydromoths or wait until Audiomoths start selling again (ends up being a trade-off between cost and time basically).

@Andrew_Hill I wonder if you could let us know more about the time keeping difference btw the regular AudioMoth and the HydroMoth (which is said to do better)?

Glad it was useful Steph.

We'll be leaving the survey open for as long as neccesary to build up a better idea of use-cases. So if any hydrophone users missed out you are more than welcome to add yours responses. We can then update the results later in the year.

Hello Aadithya,

Excited to hear about your marine acoustics outreach. I am interested to explore the possibilities of collaborative work on this line.

One of my doctoral scholars is about to submit his thesis on terrestrial acoustic studies. Please respond to jrnair@duk.ac.in (as I may likely miss responses if any, send to this group). 

Regards

Jaishanker

Hi Jaishanker, I just reached out to over email, apologies for the delay. We are interested in working with underwater hydrophones and this might be of use in your specific case study. Bristlemouth's timeline is still being created, but we're hoping to have devkits ready closer to the end of this year. I'm happy to chat more to learn about the specific research you are doing and how we can best help!

If you're looking to identify collaborators - probably lots of organizations listed in the Conservation Tech Directory would be interested (quick prelim search yields orgs like Echospace, European Tracking Network, FACT network, IMOS, IOOS, other tracking networks like that, USA's NEON, eOceans, Oceans+)! Also org's like Blue Ventures, Save our Seas (run acoustic tracking array), MBON (run Biotrack) come to mind.
