Project Grant DESC0022678

This two-year, $255,000 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will support the development of a new remote sensing technique for measuring seismic waves at Michigan Technological University. The researchers will enhance the Moiré technique, which images patterns from differential motion between grids, by placing one grid on a remote location using an unmanned aerial vehicle and the other within a base telescope. This will enable measurement of...

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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $400,000 over 3 years to the Regents of the University of Michigan to develop a novel self-powered multimodal MEMS sensor system that can simultaneously detect pH, pressure, and temperature in marine environments. The researchers aim to create an innovative, highly sensitive, and energy-efficient sensor to support marine carbon dioxide removal (MCDR) efforts by providing uninterrupted,...

This $622,016 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports the collaborative development of a novel self-powered, multimodal pH, pressure, and temperature MEMS sensor system for marine carbon dioxide removal (MCDR) monitoring. The project involves researchers from the University of North Texas, University of Michigan, and University of California San Diego working to design, fabricate, and test this innovative sensor array to provide...

This $102,704 Project Grant award from the U.S. Geological Survey's Earthquake Hazards Program (CFDA 15.807) will support the University of Alaska Fairbanks in optimizing small seismic arrays for use in the ShakeAlert earthquake early warning system. Key activities include: Analyzing existing earthquake waveform data to determine optimal array frequency and noise characteristics. Deploying a 24-sensor seismic array near Kodiak, Alaska to test diverse array configurations and evaluate their...

This National Science Foundation (NSF) Project Grant award, funded through the Mathematical and Physical Sciences (MPS) program (CFDA 47.049), provides $163,922 to the University of Arizona (Arizona Board of Regents) to develop a prototype compact and highly sensitive optomechanical seismic sensor for the Laser Interferometer Gravitational-Wave Observatory (LIGO). The sensor is intended to allow for high-quality seismic measurements below 100 MHz that are compatible with vacuum and cryogenic...

This Cooperative Agreement award from the Department of Commerce's National Institute of Standards and Technology (NIST) under the Measurement and Engineering Research and Standards program (CFDA 11.609) is focused on improving the performance of a microfabricated optomechanical sensing platform for accelerometer operation. The $127,111 award to Theiss Research, a non-profit research organization, will fund activities to increase the dimensional stability, stiffness, and mechanical quality...

This Project Grant award from the National Science Foundation Division of Ocean Sciences totals $137,255 to support the development of a plate-scale distributed strain sensing system as a candidate for earthquake early warning. Funded under the Geosciences program (CFDA 47.050), the University of California San Diego Scripps Institution of Oceanography will use the award period from October 1, 2022 to September 30, 2023 to establish the feasibility of measuring seafloor deformation along...

This Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program provides $133,077 to Syracuse University for the development of an active suspension fiber damping system to improve the duty cycle and sensitivity of the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors. The project aims to design, construct, and characterize a sensor and actuator subsystem that can mitigate the suspension resonant modes,...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) totaling $225,816 will support collaborative research to investigate the evolution of elastic wave properties during the seismic cycle. The primary objectives are to explore whether variations in seismic wave properties can be identified before and/or after earthquakes, determine the underlying physical mechanisms, and assess the potential for operational forecasting of ruptures on meter-scale...
