Project Grant DESC0024999

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 $240,377 project grant from the National Science Foundation's (NSF) Polar Programs federal grant program (CFDA 47.078) will fund the development and testing of a new capability to couple unreinforced single-mode optical fiber with melt probe technology. The goal is to greatly expand the number and distribution of temperature and geothermal flux observations from the Greenland and East Antarctic ice sheets. Specifically, the University of Washington will augment the capability of melt probes...

This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) award of $281,057 to The Trustees of Princeton University, awarded on January 1, 2025, will fund a project to explore the concept of "depth sensitive thermography" (DST) for mapping atmospheric temperatures over large scales. The project aims to develop a novel 3D temperature profiling technique that utilizes the atmosphere's varying opacity across thermal infrared wavelengths, with the goal of enabling more...

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 $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...

Federal Cooperative Agreement Award Summary Innovative Downhole Solutions LLC received a $2.51M Cooperative Agreement from the Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) under the Renewable Energy Research and Development program (CFDA 81.087) to design and construct an advanced ultrasonic measurement tool for extreme geothermal environments. The project, awarded October 1, 2025, and scheduled for completion by September 30, 2026, will deliver a specialized...

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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $350,438 to the University of California, Scripps Institution of Oceanography (SIO) to acquire and upgrade oceanographic instrumentation. The funding will enable SIO to add a suite of oceanographic sensors, including a CTD unit, altimeters, PAR sensors, and oxygen sensors, to its shared-use instrumentation pool available to researchers nationwide. Additionally, the award will allow SIO to...

This $213,500 Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) is funding Columbia University to purchase a new Conductivity-Temperature-Depth (CTD) system for the university's research vessel, the R/V Marcus G. Langseth. The CTD system will be used to collect high-quality oceanographic data, including temperature and salinity profiles, in support of NSF-funded research projects conducted on the Langseth. This award provides critical scientific...

This three-year project grant from the National Science Foundation's Geosciences program ($458,232) supports the theoretical and practical development of aragonite lithium-magnesium ratios as a proxy for reconstructing deep sea paleotemperatures. The University of Colorado will test four hypotheses to improve the theoretical underpinnings and field calibration of this emerging paleothermometer tool. Laboratory experiments will examine the temperature dependence of aragonite partition...
