Current Projects
- Understanding the Acoustic Near-field of the Kauai Beacon
PI: Eva-Marie Nosal; Co-PIs: Bruce Howe, Kai Gemba (Naval Postgraduate School)
Sponsor: Office of Naval Research, Ocean Acoustics
Previous studies have demonstrated the significant influence of near-field interactions between acoustic signals and the seafloor on long-range sound propagation. This study aims to expand upon these findings by examining the impact of local bathymetry and seabed properties on signals generated by the Kauai Beacon and received at the ALOHA Cabled Observatory, the deep portion of the Pacific Missile Test Range and ship or AUV deployed hydrophones in the area. Two and three-dimensional ray and parabolic equation models will be used to calculate along range and cross-range scattering of the signal. By considering the near-field effects in response to bathymetry and seabed in three dimensions, this work will contribute to understanding factors at play in long-range propagation, ultimately assisting in improving long-range acoustic applications, e. g., navigation and tomography. Additionally, this work will begin a publicly accessible long-term data time series of the signal to understand the ocean fluctuations, building upon the earlier Hawaii Ocean Mixing Experiment. - MAMBAT (Multiple-Animal Model-Based Acoustic Tracking): Improving underwater passive acoustic multi-target tracking methods
PI: Eva-Marie Nosal; Co-PI: Pina Gruden (CIMAR)
In collaboration Elizabeth Henderson (Navy Marine Mammal Program, NIWC Pacific) and Erin Oleson (Pacific Islands Fisheries Science Center, NOAA)
Sponsor: Office of Naval Research, Marine mammals & biological oceanography
This project aims to improve model-based passive acoustic methods for tracking multiple marine mammals, and to apply methods to new and challenging practical scenarios. We are developing and integrating a non-traditional multi-target tracking framework based on random finite sets to advance multiple-animal model-based methods. We aim to automate simultaneous tracking of multiple sources with diverse characteristics (broadband and narrowband), without requiring prior association, classification or source separation steps. The framework will be computationally efficient and will incorporate missed detections, false alarms, and source appearance and disappearance in the problem formulation. While the ultimate aim is to develop framework that is platform agnostic, method development will motivated by, tested on, and applied to large bottom mounted arrays (AUTEC and PMRF) and drifting 2-element vertical arrays (DASBRS).

Chairs: Eva-Marie Nosal and Erin Oleson
Planning, preparation and organization for the 9th International workshop on detection, classification, localization, and density estimation of marine mammals using passive acoustics - Single sensor and compact array localization methods
PI: Eva-Marie Nosal
Sponsor: Office of Naval Research, Marine mammals & biological oceanography
Prior work developed model‐based marine mammal tracking methods which incorporate sound propagation models and can consequently account for depth‐dependent sound speed profiles and multiple reflections. Although model‐based methods are generally applicable, prior work targeted large hydrophone ranges (such as AUTEC and PMRF). As a consequence, the details of implementation (which vary depending on array configuration and source characteristics) and applications are limited to these large arrays. Unfortunately such arrays are not widely available; many marine mammal projects make use of smaller arrays. This project will modify, implement and demonstrate application of model‐based localization methods for single hydrophone systems and compact arrays. - Signal processing methods for passive acoustic monitoring of marine mammals
PI: Eva-Marie Nosal; Co-PI: Anders Host-Madsen
Sponsor: US National Science Foundation
Advanced signal processing methods were developed and tested for channel estimation and blind source separation in the case of marine mammal vocalization sources propagating through the marine acoustic environment. - Improvements to passive acoustic tracking methods for marine mammal monitoring
PI: Eva-Marie Nosal
Sponsor: Office of Naval Research, Marine mammals & biological oceanography
This project investigated and implement several methods to improve the accuracy, efficiency, and applicability of model based passive acoustic methods to track marine mammals. Methods were developed and tested that:
1) Invert for sound speed profiles, hydrophone position and hydrophone timing offset in addition to animal position.
2) Use improve maximization schemes in model-based tracking.
3) Use received sound pressure levels in addition to arrival times for tracking.
This project also developed methods to simultaneously track multiple animals in cases where it is difficult/impossible to separate and associate calls from individual animals. - Acoustic monitoring of wave energy conversion devices
PI: Eva-Marie Nosal
Sponsor: US Department of Energy through the Hawaii National Marine Renewable Energy Center (HINMREC)
The goal of this project was to deploy and maintain an array of hydrophones at the HINMREC wave energy conversion device test site and analyze data to determine the acoustic signature of wave energy conversion devices installed under different sea sates, ocean conditions and operational loads. - Harbor acoustic monitoring
PI: Eva-Marie Nosal
Sponsor: US Department of Homeland Security through the Center for Island, Maritime, and Extreme Environment Security (CIMES)
This project:
1) Advanced capabilities in underwater maritime surveillance through development, testing, and deployment passive acoustic monitoring systems
2) Developed real-time techniques to 3D monitor harbor traffic, including surface vessels and underwater objects
3) Characterized acoustic source and reflectance signatures of ships, divers, swimmers, AUVs, ROVs, and other underwater craft - Acoustic seagliders in the Philippine Sea
PI: Bruce Howe; Co-PIs: Glenn Carter, Eva-Marie Nosal, Lora VanUffelen
Sponsor: Office of Naval Research (ocean acoustics program)
The project developed new techniques and technologies to improve the ability to measure and characterize the highly dynamic ocean environment and understand the effect of ocean variability due to mesoscale eddies, tides, currents, and internal waves on the acoustics. An accurate characterization of the ocean improves the predictability of acoustic propagation through it and, in turn, enables inversions for oceanic properties from acoustic receptions. The long-term goal was to use multiple platforms and techniques, old and new, acoustic and oceanographic, moored and mobile, to sense the ocean environment, and to understand the effect of oceanic fluctuations on deep-water acoustic propagation. - Passive Acoustic Methods for Tracking Marine Mammals Using Widely-Spaced Bottom-Mounted Hydrophones
PI: Eva-Marie Nosal
Sponsor: Office of Naval Research, Marine mammals & biological oceanography
This project developed and implemented methods to deal with two specific challenges associated with tracking marine mammals using widely-spaced bottom-mounted hydrophone arrays: (1) Multiple animals whose calls cannot be easily separated or associated, and (2) Insufficient receiver coverage, in which case standard time-of-arrival tracking methods fail. - Passive acoustic tracking of minke whales
PI: Eva-Marie Nosal
Sponsor: Office of Naval Research, Marine mammals & biological oceanography
This project:
1) Improved and compared passive acoustic methods for tracking minke whales.
2) Used these methods to study minke whale behavior and bioacoustics.
3) Supported test cases that involved the integration of acoustic and visual survey methods.
