Cetacean Density Estimation from Novel Acoustic Datasets by Acoustic Propagation Modeling
This project s long-term goal is the application and refinement of population density estimation methods based on detections of marine mammal vocalizations combined with propagation modeling. The density estimation method is applied to a novel acoustic data set, collected by a single hydrophone, to...
