Department Chair

Dr. Kanchan Maiti Kanchan Maiti
Chair and Shell Professor of Oceanography
225-578-4531
kmaiti@lsu.edu
Research Interests:
Research conducted at the Marine Geochemistry Laboratory led by Dr. Maiti explores interlinked topics related to transport and transformation of carbon, nutrients, and contaminants in coastal and deep ocean systems utilizing geochemical tracers and autonomous observation platforms. The availability of organic and inorganic carbon species can directly and indirectly impact various biogeochemical processes across the land-estuary-ocean aquatic continuum like formation of hypoxia, increase in ocean acidification, benthic elemental fluxes, biological carbon pump and air-sea exchange of greenhouse gases, which has implications for carbon budget at both local and global scales. Dr. Maiti’s research group seeks to provide answers to some of the fundamental questions related to ocean carbon biogeochemistry and environmental quality through field-based observations, natural isotope tracers and laboratory microcosm experiments. Current projects investigate the impacts of hurricanes on carbon budget in coastal Louisiana/Texas, carbon remineralization pathways and methane fluxes in GOM sediments, sediment driven ocean acidification in Louisiana shelf, submarine groundwater discharge in coastal Turkey, biological carbon fluxes and sediment carbon accumulation in Ross Sea, Antarctica and methane emission from orphan wells in Louisiana.
