The $314,628 award to the Woods Hole Oceanographic Institution will help quantify the heat and chemical element flow from warm fluids seeping out of the seafloor, which is a long-standing and challenging...
The Woods Hole Oceanographic Institution was awarded a $364,098 Project Grant from the National Science Foundation Division of Ocean Sciences on September 15, 2021 to complete the project by August 31, 2024. The grant was awarded under the NSF's Geosciences program (CFDA 47.050), which supports basic research to strengthen understanding of the integrated Earth system. Specifically, the grant will fund collaborative research to elucidate brine-dominated, segment-scale hydrothermal discharge along...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) project grant awarded to Lehigh University provides $141,748 to investigate nitrogen cycling in deep-sea hydrothermal vent ecosystems. The 3-year project, beginning September 1, 2024, will employ specialized high-pressure equipment to measure rates of nitrogen loss, recycling, and microbial assimilation across redox gradients at seafloor vent habitats. This research aims to enhance understanding of how these extreme...
This National Science Foundation Project Grant award of $240,688 will fund research into the effects of recent seismic activity on hydrothermal vent circulation and iron export at the Kama'ehuakanaloa underwater volcano (formerly known as Lō'ihi) located approximately 30 miles south of Hawaii's Big Island. Awarded to Woods Hole Oceanographic Institution under the Geosciences program (CFDA 47.050), this project will use a deep-diving robot to investigate whether lava was erupted on the seafloor...
The Woods Hole Oceanographic Institution received a three-year, $669,196 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences program (CFDA 47.050). The grant will support collaborative research to probe the ventilation efficiency of the deep ocean using conservative dissolved gas tracers in archived samples. As part of its mission to strengthen the national scientific enterprise through expanding fundamental knowledge of the integrated Earth...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to investigate hydrothermal alteration and marine chemistry in Proterozoic ophiolites, which are ancient pieces of ocean floor. The $328,588 award to the California Institute of Technology (Caltech) will fund analysis of iron, strontium, and oxygen isotopes in rock samples to reconstruct past ocean oxygen levels and seawater composition from 750 million to 2 billion years...
This $599,420 federal Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support research by the Woods Hole Oceanographic Institution (WHOI) to investigate controls on iron (Fe) and vanadium (V) isotope systematics during hydrothermal venting at the Kama'ehuakanaloa Seamount. The project has two main objectives: 1) Identify the drivers of coupled chemical and temperature changes in the Kama'ehuakanaloa Seamount vent fluids through elemental...
The National Science Foundation (NSF) awarded a $305,576.00 Project Grant to the Woods Hole Oceanographic Institution to study the influence of mesoscale eddies on deep-sea dynamics and larval connectivity along mid-ocean ridges. This research is funded through NSF's Geosciences program (CFDA 47.050), which supports basic research to expand fundamental knowledge and understanding of the integrated Earth system. The project will utilize a multi-scale numerical ocean model in comparison with...
Woods Hole Oceanographic Institution will provide research services under a $355,135 Project Grant award from the National Science Foundation Division of Ocean Sciences Geosciences program (CFDA 47.050). The institution will reconstruct Red Sea surface hydrography over the past 300 years using coral proxy records to examine the role of spatiotemporal climate variability in preconditioning the surface ocean for deep water formation. Specifically, the researchers will use measurements of oxygen-18...
This $321,770 federal project grant awarded by the National Science Foundation's (NSF) Geosciences program on February 1, 2024 supports collaborative research by the Woods Hole Oceanographic Institution (WHOI) to investigate links between deep and shallow volatile cycles of the Earth. The research aims to improve understanding of processes driving plate tectonics, the Earth's water and carbon cycles, and climate through analysis of seismic data and geochemical data from mid-ocean ridge rock...
The National Science Foundation (NSF) Geosciences program awarded a $626,646 Project Grant to the Woods Hole Oceanographic Institution (WHOI) to investigate how the flow of hydrothermal vents in the ocean has changed over millions of years. The project will gather, expand, compare, and analyze chemical data from marine sediments to reconstruct variations in hydrothermal metal fluxes over the Cenozoic era. This will involve modeling element concentrations, analyzing lead isotopes, and examining rare earth element patterns as tracers of past hydrothermal activity. The goal is to produce maps illustrating how and where hydrothermal plumes have been transported away from mid-ocean ridges, with implications for understanding the cycling of micronutrients like iron and critical mineral resources such as manganese, cobalt, copper, and zinc. The award also supports early career scientists and K-12 STEM outreach to underrepresented communities.
