The National Science Foundation (NSF) awarded a $315,353 Project Grant under the Geosciences program (CFDA 47.050) to the University of California San Diego's Scripps Institution of Oceanography. The grant, awarded on October 1, 2024, will fund the development of a prototype sensor called "MICRO-PHAT" that can measure seawater pH and total alkalinity in situ. This two-parameter sensor is designed to be low-power, fast, and suitable for autonomous platforms, unlike existing technologies...
This Project Grant award for $540,281 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project between U.S. and U.K. scientists to better understand the linkages between the oceanic cycles of iron and carbon. The research aims to characterize the "colloidal shunt" mechanism, whereby dissolved iron forms aggregates with organic carbon to create particulate matter that sinks out of the upper water column. The project will...
This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...
This Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) provides $226,865 to the University of Delaware to collect high-resolution carbon isotope data on GO-SHIP cruises in the Indian and Pacific Oceans. The goal is to use measurements of the ratio of carbon-13 to carbon-12 in ocean carbon dioxide to constrain estimates of ocean carbon uptake and storage, including the impacts of anthropogenic carbon dioxide. The project will deploy a specialized...
This $308,515 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to study changes in pelagic ecosystem function and their impact on the carbon cycle from the Eocene to Oligocene periods (56-33.9 million years ago). The project aims to reconstruct changes in the South Atlantic subtropical gyre ecosystem and determine how these changes affected carbonate production and preservation during a time of...
This Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research effort to analyze marine emissions of carbonyl sulfide and its contribution to the global carbon cycle. The $389,764 award will fund a multi-faceted study that combines direct marine flux measurements, dissolved gas and isotopic analysis, and data modeling. The research team, comprising institutions in the U.S., Germany, and Israel, will conduct field...
The National Science Foundation (NSF) awarded a $198,306 Project Grant under its Geosciences program (CFDA 47.050) to the University of Delaware. The grant, which runs from September 1, 2024 to August 31, 2027, supports collaborative research to synthesize polymer ionophores and fabricate potentiometric sensors for detecting carbonate ions in the ocean. The research aims to develop sensor devices with improved selectivity, response time, and long-term stability for monitoring ocean acidification...
This $908,131 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), supports research to better understand how changing phytoplankton elemental use efficiencies may impact global ocean biogeochemistry as temperatures rise. A team of U.S. and U.K. researchers, led by the University of Southern California, will conduct laboratory experiments and field work to quantify the effects of temperature on nutrient elemental use...
This National Science Foundation (NSF) Project Grant under the Geosciences program (CFDA 47.050) aims to develop new polymer ionophore materials and fabricate potentiometric sensors for detecting and measuring carbonate ion concentrations in coastal and ocean waters. The $290,800 award to Delaware State University, a historically Black land-grant institution, will fund research to synthesize polymer-based ionophores with improved selectivity and stability for long-term carbonate sensing in...
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...
