This Project Grant awarded by the National Science Foundation (CFDA 47.050 - Geosciences) will support research to understand winter nitrogen cycling and its impacts on phytoplankton communities in Lake Erie. The $295,875 award to Bowling Green State University will fund a 3-year study to: 1) measure ice onset, duration, and thickness throughout winter sampling; 2) track water column nitrogen substrate pools and transformation rates; 3) examine seasonal phytoplankton abundance and gene...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) for $111,215 will support research by the Regents of the University of Michigan to study cyanobacteria, nitrogen cycling, and export production in the Laurentian Great Lakes. The key objectives are to: 1) determine the relative contributions of cyanobacteria versus eukaryotic algae to primary production, 2) evaluate export production of cyanobacterial productivity, and 3) constrain historical...
This National Science Foundation (NSF) Project Grant award for $425,311 to the Carnegie Institution for Science supports collaborative research on how winter conditions affect the ecological function of seasonally-frozen lakes. The multi-year project (11/1/2023 - 10/31/2027) will develop a comprehensive, predictive model of year-round lake ecosystem dynamics by: Conducting detailed seasonal studies of water quality, plankton populations, food webs, and organic matter cycling in 12 lakes with...
This Project Grant award from the National Science Foundation's (NSF) Geosciences program totaling $429,823 supports a collaborative research effort to investigate the Holocene biogeochemical evolution of the Great Lakes. The research team from Central Michigan University and Michigan State University will collect sediment cores from Lakes Superior, Huron, and Erie to analyze elemental and isotopic geochemical cycles over geologic time. This work will provide insights into past productivity,...
This National Science Foundation (NSF) Geosciences program Project Grant award of $518,578 to Michigan State University (MSU), with a period of performance from March 1, 2024 to February 28, 2027, will investigate the Holocene biogeochemical evolution of the Great Lakes system. The project will collect sediment cores from Lakes Superior, Huron, and Erie to analyze geochemical proxies, including mercury isotopes, nutrient concentrations, and redox-sensitive elements. This research aims to...
The National Science Foundation (NSF) Division of Environmental Biology awarded a $130,123 Project Grant to the University of Wisconsin System at the University of Wisconsin - Madison, with a project period from November 1, 2023 to October 31, 2027. The funding supports collaborative research to develop a comprehensive model of year-round ecosystem function in seasonally frozen lakes, addressing the "winter knowledge gap" in understanding how changing winter conditions impact lake...
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 for $291,764 from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to study a newly discovered Synechococcus ecotype that has lost the ability to utilize nitrate, a key process in the marine carbon cycle. The project will: (1) collect and isolate this novel Synechococcus strain from the iron-limited Northeast Subarctic Pacific, (2) determine the seasonal and spatial dynamics of different Synechococcus nitrogen-utilization ecotypes in this...
The National Science Foundation (NSF) Division of Environmental Biology awarded a $300,000 Project Grant to Michigan Technological University to develop and test modeling approaches that quantify denitrification and nitrogen fixation in streams. The grant, which runs from January 1, 2024 to December 31, 2025, supports research to improve understanding of nitrogen cycling and removal in freshwater ecosystems. The project aims to create open-source models that can estimate denitrification rates in...
The National Science Foundation awarded the University of Maryland Eastern Shore a three-year $499,999 Project Grant under the Integrative Activities program (CFDA 47.083) to conduct research on river plume dynamics in Lake Michigan. The university will use coupled hydrodynamic and ice numerical models to investigate the effects of wave-current-ice interactions on coastal plume formation and plume behavior under climate change scenarios in the southern basin. A subaward of $75,741 was issued...
