Sounds of Atlantic sturgeon spawning: first description and opportunities for riverine endangered species conservation with passive acoustic monitoring

Endangered Species Research
Effective recovery plans for endangered species rely on insights into species’ ecology to identify risks and develop population recovery strategies.

Using Ocean Ambient Sound to Measure Local Integrated Deep Ocean Temperature

Geophysical Research Letters
Measuring the temperature changes of the deep ocean will be critical to understanding how the earth system will respond to climate change. In this work, we present a method for measuring the depth‐averaged, deep ocean temperature at local (∼3 km) spatial

Monitoring Grassland Bird Communities with Acoustic Indices

Birds
Several researchers have tried to find relationships between acoustic indices and vocal animal communities to use acoustic indices as a passive monitoring method, as human-derived surveys are expensive, time-consuming, and suffer from observer bias ...

Eastern Black Rail detection using semi-automated analysis of long-duration acoustic recordings

Avian Conservation and Ecology, 2021
Detecting presence and inferring absence are both critical in species monitoring and management. False-negatives in any survey methodology can have significant consequences when conservation decisions are based on incomplete results.

Random Forest for improved analysis efficiency in passive acoustic monitoring

Ecological Informatics, 2014
Abstract Passive acoustic monitoring often leads to large quantities of sound data which are burdensome to process, such that the availability and cost of expert human analysts can be a bottleneck and make ecosystem or landscape-scale projects infeasible.

Mapping of Acoustic Noise and Microwave Radiation

Cybernetics and Information Technologies, 2016
Passive sensor systems are attractive for monitoring due to the absence of probing emissions. Two passive systems: an acoustic camera, manufactured by Brüel & Kjær (Sound and Vibration Measurement A/S) and a microwave radiometer are considered in the ...

Marine Fiber-Optic Distributed Acoustic Sensing (DAS) for Monitoring Natural CO₂ Emissions: A Case Study from Panarea (Aeolian Islands, Italy)

Applied Sciences
Submarine gas emissions represent a key expression of fluid migration processes in volcanic and hydrothermal marine environments and provide valuable analogues for monitoring strategies relevant to sub-seabed carbon storage.

The use of a camera trap and acoustic survey design to ascertain the vocalization and breeding status of the highly elusive White-winged Flufftail, Sarothrura ayresi

Avian Conservation and Ecology, 2020
The critically endangered White-winged Flufftail, Sarothrura ayresi, was first described in 1877 and yet significant data deficiencies in the vocalization and breeding status of this species still exist.

Impact of parameterization in multiple acoustic index comparisons: practical cases in terrestrial and underwater soundscapes

Remote Sensing in Ecology and Conservation
Acoustic indices are increasingly used to characterize soundscapes and infer biodiversity patterns in terrestrial and marine environments. However, methodological choices during data collection and signal processing—particularly the selection of sampling
