Use of an unmanned aerial‐aquatic vehicle for acoustic sensing in freshwater ecosystems

Remote Sensing in Ecology and Conservation, Volume 10, Issue 3, Page 343-359, June 2024.
In this article, we integrate water surface and underwater acoustic monitoring equipment onto a prototype unmanned aerial‐aquatic vehicle (UAAV) capable of sailing and flight (SailMAV), to demonstrate how robotics can facilitate acoustic sensing in freshwater ecosystems. Results show higher species richness and call abundance from UAAV surveys and high
