Kanchan Maiti headshotKanchan Maiti
Associate Professor and Shell Professor in Oceanography/Wetland Studies
225-578-4531
kmaiti@lsu.edu
Research Interests:
My research group focuses on understanding the fate and transport of different forms of carbon in coastal and deep ocean. Photosynthetic fixation of CO2 in surface ocean into different forms of organic carbon effectively removes CO2 from atmosphere. In absence of this process, our atmospheric CO2 concentration would have been ~50% higher than it is at present times. Understanding this process known as the “biological pump” is extremely important in determining the role of ocean in controlling atmospheric CO2and how that might change in future. However a large fraction of this organic carbon fixed by phytoplankton in the ocean gets released back into the water column and atmosphere as CO2 and other inorganic forms of carbon via respiration and microbial decomposition. Thus the availability of organic carbon can directly and indirectly impact various biogeochemical processes in the ocean like formation of hypoxia, increase in ocean acidification, release of various redox sensitive elements and contaminants from the sediments. My research group at LSU seeks to provide answers to some of these fundamental questions related to ocean carbon biogeochemistry and environmental quality through field based observations, natural isotope tracers and laboratory microcosm experiments. Current research themes include: Upper ocean particle dynamics and biological pump, fate and transport of organic matter and contaminants in aquatic systems, utilization of artificial and natural radioisotopes to study environmental processes, sediment geochemistry and chemical processes at sediment-water interface, and ocean acidification.

My current agenda encompasses three main topics: 1) Wetland response to sea level rise, sediment supply and storminess. 2) Coupled dynamics of sediment & biofilms / microbial-mats. 3) Carbonate platform sedimentary processes.
