This federal Project Grant award, funded by the Office of Naval Research (ONR) under the Basic and Applied Scientific Research program (CFDA 12.300), provides $150,000.00 to the New Jersey Institute of Technology (NJIT) to conduct a simulation study assessing accuracy, uncertainty, and consistency in geoacoustic inversion across methodologies. The award has a performance period from December 1, 2024 to November 30, 2027. NJIT, a public polytechnic research university, will leverage its expertise...

This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award to the University of California San Diego (UCSD) Scripps Institution of Oceanography for $346,290 will fund research to develop new computational methods for geophysical data inversion and uncertainty quantification. The project, titled "Beyond Occam: Model Construction and Uncertainty Quantification in Geophysics," aims to generate models that can accurately reproduce sharp contrasts in...

This $249,924 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports the development of a long-lived, continuously operating seafloor geodesy reference station capable of operating in deep water. The grantee, Princeton University, will investigate using acoustic signals that only need to travel from the sea surface to the seafloor, removing the prior 3,000 meter depth limitation of existing seafloor geodesy techniques. This new approach involves...

This three-year, $170,000 National Science Foundation Mathematical and Physical Sciences Project Grant will support research into new geometric inverse problems arising from seismology at North Carolina State University. The award seeks to advance the mathematical theory of seismology by posing and solving increasingly complex and realistic inverse problems modeling planetary interiors. Specifically, the grantee will investigate non-Riemannian travel time problems considering both complete and...

Northeastern University was awarded a $1,279,032 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to upgrade and test the Passive Ocean Acoustic Waveguide Remote Sensing (POAWRS) system. POAWRS is a 160-element coherent hydrophone array technology developed for long-range directional sensing and real-time detection, localization, and mapping of various ocean sound sources over continental shelf scales. Under...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $1,354,056 to the University of California San Diego Scripps Institution of Oceanography to jointly implement a new measurement technique called distributed acoustic sensing. This technique will generate high-resolution (10 m in space, minutes in time) images of ocean temperature and current velocity fields above a 34-km cable laid on the seafloor off the Azores islands. The goal is to...

This National Science Foundation (NSF) Technology, Innovation, and Partnerships (TIP) program (CFDA 47.084) Project Grant award of $550,000 to Northeastern University is for the development of compact, coherent hydrophone array systems for real-time, wide-area ocean acoustic monitoring. The project aims to translate the Passive Ocean Acoustic Waveguide Remote Sensing (POAWRS) technology, which uses advanced hydrophone arrays to provide continental-scale ocean sensing capabilities, into...

The University of Texas at Austin Applied Research Laboratories (UT Austin ARL) was awarded a $312,500 Project Grant from the Office of Naval Research under the Basic and Applied Scientific Research program (CFDA 12.300) to conduct research on the complexities and dynamic nature of fine-grained ocean-bottom sediments and their impact on shallow water acoustic propagation. This 3-year award, running from August 1, 2024 to July 31, 2027, aims to advance the scientific understanding of how seafloor...

This $525,000 Project Grant was awarded by the National Oceanic and Atmospheric Administration (NOAA) under the NOAA Small Business Innovation Research (SBIR) Program (CFDA 11.021) to Loggerhead Instruments Inc., a for-profit manufacturer of advanced environmental monitoring technologies based in St. Petersburg, Florida. The grant funding will support the development of POGO, a low-cost underwater vehicle for passive acoustic recording that can be deployed and recovered from near-shore...

This $270,000 Project Grant award from the National Science Foundation (NSF) Mathematical and Physical Sciences (CFDA 47.049) program supports research at the University of California, Irvine (UC Irvine) to develop novel mathematical methods for investigating inverse problems related to the recovery of anisotropic medium parameters from measurements taken at the exterior or boundary. The project aims to leverage nonlocality, nonlinearity, and high frequencies as tools to tackle significant and...
