This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project to assess global ocean oxygen inventory, trends, and variability. The $563,629 award to the Georgia Tech Research Corporation, which will run from May 1, 2025 to April 30, 2028, has two primary goals: 1) to identify the causes of disagreements between different gridded oxygen datasets through an intercomparison of data from in situ observations and...
This Project Grant award, with a total funding amount of $309,557, was provided by the National Science Foundation (NSF) through its Geosciences program (CFDA 47.050). The purpose of the project is to investigate the fate of nitrogen in amino acids and the processes that contribute to the formation of refractory dissolved organic nitrogen (DON) in the ocean. Using stable isotope probing and advanced mass spectrometry techniques, the study will trace the transformation of different amino acids...
The National Science Foundation Division of Ocean Sciences awarded a $347,930 Project Grant to the Georgia TECH Research Corporation, doing business as the Office Of Sponsored Programs, to support the project "MAPPING DISSOLVED OXYGEN USING OBSERVATIONS AND MACHINE LEARNING" from August 15, 2021 through July 31, 2024. The project aims to strengthen understanding of the integrated Earth system through the use of machine learning techniques to map dissolved oxygen levels based on...
The National Science Foundation Division of Ocean Sciences awarded a $256,224 Project Grant to Texas A&M University under the Geosciences program (CFDA 47.050) from January 1, 2023 to December 31, 2025. The grant funds research to examine how northward flowing water masses are modified in the tropical Atlantic Ocean before reaching the North Atlantic through advecting Lagrangian particles and tracers for 60 years in two versions of the MOM6 global ocean model. The research aims to provide...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $113,988 to the University of California, Santa Barbara (UCSB) aims to improve understanding of the biological carbon pump in ocean oxygen minimum zones. The researchers will conduct field observations in the Eastern Tropical North Pacific to measure characteristics of sinking particulate organic carbon, including particle abundance, size, sinking rates, and remineralization. These data will be...
This three-year Project Grant from the National Science Foundation Division of Ocean Sciences provides $185,519 to The Trustees of Columbia University for collaborative research probing the ventilation efficiency of the deep ocean with conservative dissolved gas tracers in archived samples. The research directly supports the goals of the NSF's Geosciences program (CFDA 47.050) to strengthen understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean...
This $292,831 project grant awarded by the National Science Foundation's Geosciences program aims to simultaneously measure nitrous oxide (N2O) production and consumption in ocean environments with varying dissolved oxygen levels. The research will be conducted by Arizona State University and will: 1) quantify N2O production and consumption rates as dissolved oxygen decreases from oxic to anoxic conditions, 2) determine the degree to which N2O consumption in anoxic zones balances increased...
This National Science Foundation Project Grant award of $533,300 provides funding from March 1, 2023 through February 28, 2026 to the University of Texas at Austin for research investigating links between physical surface processes, ocean oxygenation, and organic carbon burial during the establishment of the South Atlantic Ocean from 150-100 million years ago. The goal is to better understand how the opening of a major oceanic gateway affected depositional responses to local basin settings,...
This Project Grant award of $300,774, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to understand how efficient particulate organic carbon transfer occurs in the ocean's oxygen minimum zones. The University of Rochester will conduct observations and modeling to test three hypotheses about how low oxygen conditions in these regions impact the size distribution and remineralization of sinking carbon particles. Key datasets will include particulate...
The University of Texas at Austin has been awarded a $463,487 project grant from the National Science Foundation (NSF) Geosciences program (CFDA 47.050) to investigate drivers and impacts of heat and freshwater changes in the North Atlantic Ocean. The project, titled "Drivers and Impacts of North Atlantic Freshwater and Heat Fluxes Unsettling Modern-Day Climate (DIMSUM)", will use observations, model-based tools, and novel analysis techniques to quantify heat and freshwater budgets,...
