Robin Sandfort @capreolus | he/him Capreolus e.U. wildlife biologist with capreolus.at Groups Acoustics Hi Everyone,what is your #HydroMoth setup for freshwater ecoacoustic monitoring? What are your settings for underwater recording with your AudioMoth? I would love to dicuss your solutions.Greetings from Austria,Robin Expand all Collapse all Oldest first Latest first Most popular Jacob Levenson @Jlevenson Marine biologist who studies big things that swim...mostly. 29 January 2023 12:44pm Hi Robin,Did you ever get any responses to your query? Just recovered a hydromoth I was testing for MPA monitoring, but all the files have no audio on them. Was curious what others were doing underwater. Jake 1 Reply Robin Sandfort 29 January 2023 12:44pm Hi Jacob, you are the first one but I have been talking to other scientist about their projects. Right now we are recording and hopefully automatically detecting Eurasian otter (Lutra lutra) vocalisations.Did you find out why your files were empty or was the sound level just too low?Greetings from Austria,Robin X Reply Ian Flinders @IanofBrisbaneAustralia Multi species distribution research sp now on Microchiroptera and Platypus 12 May 2023 6:53am I am interested in this.I intend to apply Hydromoths for location of Platypus Ornithorhynchus anatinus in local creeks. Visual surveys have produced signifcant results. Any success with otters in Europe may be helpful.I would be looking at producing bioacoustic algorithm identifiers. 3 Replies Frontier Labs Australia 12 May 2023 6:53am Hi Ian, are you in Brisbane? We're based in Brisbane also. You can borrow a few BARLT and Aquarian Audio hydrophones for a little while to compare against your hydromoth. We have localisation also using the inbuilt GPS and software to time align the calls. It'll probably save you time. You can run a microphone and hydrophone on a cable on the one recorder. Robin Sandfort 12 May 2023 6:53am Hi Ian, the otter detection works great but we recorded the otter calls with the Hydromoth outside of the water. Do you plan on recording Platypus underwater? Vicki Hallett 12 May 2023 6:53am Hi Ian,I have hours of an unidentified creature recorded during overnight recording sessions with mutliple hydrophones. We think it is platypus but there is nothing to compare against that isn't from captive sounds. I am waiting on the Hydromoth to become available again so I can do longer term monitoring. 👍🏽 1 X Reply Want to share your own conservation tech experiences and expertise with our growing global community?
