Hi Enis, it seems a very interesting project. I myself with my team are currently working with the non-stationary of physiological and earthquake seismic public data mainly based on the time-frequency distributions, and the results are very promising.
Just wondering if the raw data that you've mentioned are available publicly so we can test our techniques on them or they're only available through research collaborations. Either way very much interested on the potential use of our techniques for the polar research in Arctic and/or Antarctica.
Hi teleforce, thanks! Your project sounds very interesting as well.
That actually reminds me, at one point, a researcher suggested looking into geophone or fiber optic Distributed Acoustic Sensing (DAS) data that oil companies sometimes collect in Alaska, potentially for tracking animal movements or impacts, but I never got the chance to follow up. Connecting seismic activity data (like yours) with potential effects on animal vocalizations or behaviour observed in acoustic recordings would be an interesting research direction!
Regarding data access:
Our labeled dataset (EDANSA, focused on specific sound events) is public here: https://zenodo.org/records/6824272. We will be releasing an updated version with more samples soon.
We are also actively working on releasing the raw, continuous audio recordings. These will eventually be published via the Arctic Data Center (arcticdata.io). If you'd like, feel free to send me an email (address should be in my profile), and I can ping you when that happens.
Separately, we have an open-source model (with updates coming) trained on EDANSA for predicting various animal sounds and human-generated noise. Let me know if you'd ever be interested in discussing whether running that model on other types of non-stationary sound data you might have access to could be useful or yield interesting comparisons.
