Site specific probability of passive acoustic detection of humpback whale calls from single fixed hydrophones.

Passive acoustic monitoring of marine mammal calls is an increasingly important method for assessing population numbers, distribution, and behavior. A common mistake in the analysis of marine mammal acoustic data is formulating conclusions about these animals without first understanding how environmental properties such as bathymetry, sediment properties, water column sound speed, and ocean aco...

Feasibility Study of Real-time and Automated Monitoring of Iranian Rivers using 50-kHz Fluvial Acoustic Tomography System

Acoustic Tomography (AT) technique is an innovative method for real-time river monitoring. In this study, not only the accuracy of flow velocity measurement using 50 kHz AT system which is appropriate for narrow rivers (most Iranian rivers) is evaluated, but also its performance is compared with 30 kHz one which is used in wide rivers. The comparison results showed that the velocity resolutions...

Passive Acoustic Monitoring for the Detection and Identification of Marine Mammals

This project is a multi-pronged study to advance the state of the field in three areas. The development of automated auditory scene analysis for delphinid tonal calls will permit subsequent work by this investigator or others to exploit the use of whistles for classification and localization. Our approach is to dynamically build hypothesis graphs using phase-frequency representations of the sig...

Automated Passive Acoustic Tracking of Dolphins in Free-ranging Pods

Research in passive acoustic detection and localization of marine mammals has largely focused on isolated cases of single or few individuals. However, many marine mammals, such as dolphins, characteristically aggregate in large pods. In addition, dolphins vocalize frequently, emitting broadband clicks and frequency-modulated whistles, which, coupled with a large number of individuals, further c...
