Project Grant 2446500
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports fundamental research to expand scientific understanding of the integrated Earth system through investigations in the atmospheric, earth, and ocean sciences. The $290,552 award will recover, calibrate, and analyze oxygen data from an array of moorings in the Labrador and Irminger Seas in the North Atlantic Ocean. This will help characterize oxygen and carbon dioxide ventilation pathways into...
- This $1,119,712 federal Project Grant award was provided by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050) to the Woods Hole Oceanographic Institution (WHOI). The primary goal of the project is to recover, calibrate, and analyze oxygen data from an array of moorings in the Labrador and Irminger Seas in the North Atlantic Ocean. The new oxygen observations will help characterize the pathways of dissolved gases into the ocean interior, which is critical for...
- This $563,629 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports a collaborative research project to assess global oxygen inventory, trends, and variability through the intercomparison of observation-based gridded datasets. The key objectives are to: 1) identify causes of disagreements between different gridded oxygen datasets by conducting an intercomparison of oxygen data from in situ observational and model-based profiles, and 2) promote...
- 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 National Science Foundation project grant of $328,355 will fund research into nitrogen isotope dynamics on the Amundsen Sea continental margin in Antarctica under the Geosciences program (CFDA 47.050). Trustees of Boston College, doing business as Boston College, will collect full water column profiles of nitrogen and oxygen isotope ratios in nitrate along with isotope ratios of total dissolved nitrogen at select stations during the U.S. GEOTRACES GP17-ANT expedition. Suspended particle...
- This $184,955 project grant was awarded by the National Science Foundation's Geosciences program (CFDA 47.050) to San Jose State University Research Foundation, doing business as San Jose State University. The project aims to 1) estimate the uptake, transport, and storage of carbon in the North Atlantic Ocean using new data and modeling approaches, and 2) quantify the role of the Atlantic Meridional Overturning Circulation (AMOC) in driving variability in the North Atlantic carbon sink. The...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) is focused on investigating benthic iron fluxes in the Labrador Sea, a critical region for deep-water formation and biological carbon cycling. The $134,212 award to the Woods Hole Oceanographic Institution will support research to identify and quantify iron sources from ocean sediments to the overlying waters, using sediment sampling, pore water analysis, and numerical ocean circulation modeling....
- This $125,722 National Science Foundation project grant supports research to develop an effective ocean oxygen sampling strategy through 2026. Funded under the Geosciences program (CFDA 47.050), the University of Texas at Austin will use existing oxygen observations and numerical models to calculate float populations and distributions needed to resolve oxygen changes over space and time. Models will also assess how historical and additional oxygen data can reduce uncertainty in understanding...
- This three-year, $177,799 National Science Foundation Project Grant through the Geosciences program (CFDA 47.050) will fund research to advance understanding of glacial-age western North Atlantic hydrography. The Woods Hole Oceanographic Institution will synthesize existing sediment property data from 30% more deep-sea sediment cores collected between 1994 and 2021. Isotopic and radiocarbon analyses of microfossils from cores spanning the upper 2 km of the region will provide new insights into...
- The University of Massachusetts Boston (UMB), as prime awardee, was awarded a $141,024 project grant from the National Science Foundation Division of Ocean Sciences under the Geosciences program (CFDA 47.050) to conduct research from July 1, 2023 to June 30, 2026. UMB will reconstruct past variations in oxygen-deficient zones of the eastern tropical North Pacific Ocean by measuring nitrogen isotopes trapped in fossil plankton in a deep-sea sediment core. Researchers will analyze four time...
The National Science Foundation (NSF), through its Geosciences program (CFDA 47.050), awarded a $333,276 project grant to Trustees of Boston College, doing business as Boston College, to recover, calibrate, and analyze oxygen data from an array of moorings in the Labrador and Irminger Seas in the North Atlantic Ocean. The primary goal of this collaborative research project is to advance the understanding of how the uptake of oxygen and carbon by the ocean might be changing and how these changes are related to circulation changes in the North Atlantic Ocean. The new oxygen observations will help characterize the pathways of dissolved gases into the ocean interior, allowing for better extrapolation from oxygen to carbon cycling and examination of the mechanisms that drive the sinking and mixing of surface waters as they move into the deep ocean. This research is expected to be completed by July 31, 2028.
