The Development of a Low-Cost Hydrophone for Passive Acoustic Monitoring of Dolphin's Vocalizations

Remote Sensing, 2023
Passive acoustics are widely used to monitor the presence of dolphins in the marine environment. This study aims to introduce a low-cost and homemade approach for assembling a complete underwater microphone (i.e., the hydrophone), employing cheap and ...

Shifts in acoustic signature of Southern Hemisphere fin whales: Declining peak frequency of high-frequency components [PDF]

JASA Express Letters
Population-specific acoustic features are vital for using passive acoustic monitoring to study marine mammal populations in remote regions. Southern Hemisphere fin whale (Balaenoptera physalus) songs include region-specific high-frequency components ...

Automatic acoustic detection of birds through deep learning : the first bird audio detection challenge [PDF]

, 2018
Assessing the presence and abundance of birds is important for monitoring specific species as well as overall ecosystem health. Many birds are most readily detected by their sounds, and thus passive acoustic monitoring is highly appropriate. Yet acoustic
