Research & Activities:

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.
