Project Grant 2342978
- This $1,038,171 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research into methane efflux from river-influenced coastal marine sediments in the Gulf of Mexico. The Louisiana Universities Marine Consortium will measure methane fluxes from coastal sediments into Gulf waters using an in situ lander to collect benthic flux measurements of oxygen and methane. Sediment microprofiles of oxygen and sulfide will also be analyzed. Naturally occurring...
- This three-year, $294,092 National Science Foundation project grant will fund research at the University of Rochester to improve understanding of open ocean methane sources and sinks. The research aims to determine dominant biological sources of methane in surface waters through modeling of methane concentration data. The model will quantify methane supply from seafloors in low-oxygen zones and whether this methane is consumed before escaping to the atmosphere. The optimized global model will...

The three-year award, made under the Geosciences program (CFDA 47.050), will support collaborative research from April 1, 2021 to March 31, 2024. The Geosciences program seeks to strengthen understanding of the integrated Earth system through basic research in...
- The National Science Foundation awarded a $410,518 three-year Project Grant to The University of Puget Sound under the Geosciences program (CFDA 47.050) to conduct research on aerobic methane production in ocean environments. The university will collaborate with scientists in the U.S. and Israel to study the microbial processes that produce methane through the degradation of organic compounds in the surface waters of the North Pacific and North Atlantic oceans. Researchers will measure methane...
- This two-year, $286,876 National Science Foundation Division of Ocean Sciences project grant funds research into bi mediated corrosion of methane-derived authigenic carbonates in deep ocean environments and its implications for carbon fluxes from methane seeps. The University of California, Los Angeles will investigate the amount of carbon released into seawater through biological processes that dissolve the carbonate rock structures formed at oceanic methane seeps. The research will quantify...
- The National Science Foundation (NSF) awarded Northeastern University a $354,605 Project Grant under the Geosciences program (CFDA 47.050) to synthesize data on the role of shallow benthic fluxes in the coastal carbon cycle along the East Coast of the United States. The project, titled "COLLABORATIVE RESEARCH: ULTRA-DATA: SYNTHESIZING THE ROLE OF SHALLOW BENTHIC FLUXES IN COASTAL CARBON CYCLE ALONG THE EAST COAST OF THE UNITED STATES", will involve a literature review, data evaluation,...
- This two-year, $544,624 National Science Foundation project grant funds research on methane venting from seafloor faults in Puget Sound, Washington. The University of Washington will measure methane gas flows from newly discovered bubble plumes on the seafloor using a remotely operated vehicle to place instruments directly in the gas streams. Graduate and undergraduate students, including five from underrepresented communities of color, will participate in shipboard and laboratory work. The...
- The University of Georgia Research Foundation, Inc. was awarded a $199,278 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to measure methane efflux from river influenced coastal marine sediments. Over a three year period ending in September 2025, the awardee will conduct fieldwork during two cruises off the southeastern coast of Louisiana to directly measure benthic fluxes of oxygen and methane using in situ...
- This National Science Foundation (NSF) Division of Ocean Sciences award under the Geosciences program (CFDA 47.050) provides $104,679 to Claremont McKenna College from June 1, 2023 to July 31, 2024 to conduct collaborative research on reconstructing a 250-year history of environmental conditions in the Gulf of Maine. The research team will use geochemical proxies in marine climate archives, such as growth bands in clams and crustose coralline algae, to generate multi-centennial,...
- This $440,044 federal Project Grant awarded by the National Science Foundation's (NSF) Division of Ocean Sciences aims to improve understanding of the role of the Atlantic Meridional Overturning Circulation (AMOC) in driving variability in the North Atlantic carbon sink. The Massachusetts Institute of Technology (MIT) will lead a collaborative research project with partners in the US and UK to 1) estimate carbon uptake, transport, and storage in the North Atlantic using new data and numerical...
COLLABORATIVE RESEARCH: DRIVERS AND DYNAMICS OF METHANE SEEPAGE ALONG THE US ATLANTIC MARGIN -METHANE PLAYS AN IMPORTANT ROLE IN CONTROLLING CLIMATE ON EARTH. RECENTLY IT HAS BEEN FOUND THAT METHANE IS SEEPING FROM THE SEAFLOOR INTO THE ATLANTIC OCEAN ALONG THE EASTERN UNITED STATES. METHANE SEEPS LIKE THESE MAY BE COMMON ALONG SIMILAR COASTLINES AND THUS MAY AFFECT OUR CLIMATE. THE REASONS FOR THESE METHANE SEEPS WILL BE STUDIED USING GEOLOGICAL, CHEMICAL, AND BIOLOGICAL METHODS. THE PROJECT SUPPORTS STUDENTS AT VARIOUS LEVELS AND CONTRIBUTES TO PUBLIC UNDERSTANDING OF THE OCEAN THROUGH TALKS, PUBLICATIONS, AND VIDEOS. SUMMER CAMPS DESIGNED TO INSPIRE THE NEXT GENERATION OF OCEAN SCIENTISTS WILL BE DEVELOPED. THE FIELD WORK AND COMMUNITY OUTREACH WILL IMPROVE OUR UNDERSTANDING OF METHANE'S ROLE IN CLIMATE AND CONTRIBUTE TO PUBLIC UNDERSTANDING OF AND APPRECIATION FOR OCEAN SCIENCE. THIS PROJECT WILL STUDY BIOGEOCHEMICAL AND GEOLOGICAL CONTROLS ON RECENTLY DISCOVERED METHANE SEEPS IN THE NORTHERN US ATLANTIC MARGIN (200-1000M DEPTH). EXISTING CONCEPTUAL MODELS OF THE ORIGIN, SUBSURFACE MIGRATION, CHARACTERISTICS, AND HISTORY OF METHANE DISCHARGE ALONG CONTINENTAL MARGINS WOULD NOT PREDICT THE WIDESPREAD PRESENCE AND DEPTH DISTRIBUTION OF THESE SEEPS. THIS WORK WILL INTEGRATE GEOCHEMICAL, MICROBIOLOGICAL, GEOPHYSICAL, AND GEOLOGICAL DATA TO INVESTIGATE THE GENESIS OF SEEP FLUIDS, FLUID MIGRATION, AND METHANE OXIDATION PROCESSES IN A MODERN SEEP WHILE RECONSTRUCTING METHANE SEEPAGE CHARACTERISTICS AND GAS HYDRATE STABILITY IN THE PAST. THE PROJECT WILL COMBINE GEOPHYSICAL CHARACTERIZATION WITH THE AUTONOMOUS UNDERWATER VEHICLE SENTRY AT ACTIVE SEEP SITES. THIS WILL BE COMBINED WITH GRAVITY AND JUMBO PISTON CORING FROM SHIPS AS WELL AS TARGETED SAMPLING USING THE HUMAN OCCUPIED DEEP SUBMERGENCE VEHICLE ALVIN. THIS STRATEGY WILL RETRIEVE MULTISCALE SEAFLOOR AND SUB-SEAFLOOR DATASETS, CAPTURING A RECORD LONGER THAN PREVIOUSLY RECOVERED AT ANY OTHER SEEP ALONG THIS MARGIN. THE MULTI-PRONGED APPROACH WILL CONTRIBUTE TO AN INTEGRATED AND MECHANISTIC UNDERSTANDING OF CONTINENTAL MARGIN METHANE SEEPS. THIS PROJECT IS JOINTLY FUNDED BY THE DIRECTORATE FOR GEOSCIENCE?S CHEMICAL OCEANOGRAPHY AND MARINE GEOLOGY AND GEOPHYSICS PROGRAMS AND BY THE ESTABLISHED PROGRAM TO STIMULATE COMPETITIVE RESEARCH (EPSCOR). THIS AWARD REFLECTS NSF'S STATUTORY MISSION AND HAS BEEN DEEMED WORTHY OF SUPPORT THROUGH EVALUATION USING THE FOUNDATION'S INTELLECTUAL MERIT AND BROADER IMPACTS REVIEW CRITERIA.- SUBAWARDS ARE NOT PLANNED FOR THIS AWARD.
