Jaye Cable

Chair, Curriculum for Environment and Ecology and Professor, Department of Marine Science University of North Carolina Chapel Hill

read bio

Dr. Cable’s research focuses on hydrologic processes at the land-sea boundary, with an emphasis on sources, sinks, and transformations of biogeochemical constituents to coastal water bodies. Current projects include:
• Hydrologic interactions between coastal aquifers and marine surface waters systems, specifically investigating the role paleochannels play in deltaic systems as a vast subterranean estuary network (Mississippi River Delta; EAR 1141685)
• Characterization of hydrologic and biogeochemical processes across the tidal creek-salt marsh interface and export to the ocean, specifically quantifying water and DOC export in a Florida salt marsh (Econfina-Aucilla Rivers, Florida; OCE 0928162)
• Radionuclide applications in marine and environmental processes (e.g., sediment accretion, resuspension, and water mass tracing)
This research is currently supported by grants from NSF.
