This project is refining methods for using the data housed in the Navy’s passive acoustic marine mammal monitoring data system, M3, to characterize whale behavioral responses to survey vessels and other disturbances, and to analyze fin whale vocalization behavior in the North Atlantic.

This project will test a suite of methods to identify calls of both baleen and toothed whales in tag data to identify which of the detected calls are associated with the tagged individual. This will help the Navy’s monitoring program to estimate densities and evaluate behavioral responses.

This project will enhance the shared software package, Raven-X, and increase speed and efficiency of bioacoustics data processing.

This project will focus on archiving an extensive set of passive acoustic data, collected over ten years, by the Scripps Whale Acoustic Laboratory under Navy funding. Work will be coordinated with National Centers for Environmental Information (NCEI). This effort will protect the Navy’s investment and ensure the continued availability of the data.

This effort will develop information needed to determine the feasibility of using animal cue rate (calling rate) and the cue stability for acoustic density estimation.

This project is working to demonstrate and refine a suite of density estimation methods using data from sparse arrays, in which sensors may be distributed evenly but widely over a large area of interest. Sparse array examples include Ocean Bottom Seismometers (OBS) and Comprehensive Nuclear Test Ban Treaty Organization International Monitoring System (CTBTO IMS) recorders.

This project is focused on demonstrating passive acoustic density estimation methods and validating these methods using concurrent visual density estimation techniques.

This project is reviewing the US Navy Marine Species Monitoring (MSM) program and will make recommendations for how future efforts can inform future Population Consequences of Disturbance (PCoD) analyses.

This project is working to provide a comprehensive, quantitative synthesis of the current state of knowledge on acoustic cue rates and cue stability for marine mammal density estimation from passive acoustics.

This effort is coordinating a group of density surface modeling (DSM) specialists to assess the varied approaches to and coordinate advances on using DSM models. These experts are focused on developing and implementing innovative approaches to improve spatial modeling methods used to characterize seasonal abundance and distribution of marine species, particularly in U.S. Navy training and testing areas.
