My research focuses on chemical oceanography and the effects of climate change on biogeochemical cycles. In particular, I am interested in how the multi-stressors of global climate change will impact the future production of the anti-greenhouse gas dimethylsulfide (DMS) and its precursor molecule dimethylsulfoniopropionate (DMSP). Throughout my graduate career I will examine the interactions of planktonic and microbial cycling of the DMS(P) system to determine whether future climate conditions will hinder or propel production of DMS and how these changes will influence marine carbon cycling and the Earth’s climate.
I am a Ph.D. student of Ocean Sciences, co-advised by Dr. Naomi M. Levine and Dr. Burt H. Jones. My dissertation research involves addressing the impacts of predicted climate changes on phytoplankton assemblage composition and particulate material export in the ocean using both satellite remote sensing and numerical ecosystem modeling approaches. I am particularly interested in understanding the role that small-scale physical dynamics play on large-scale climate-ecosystem interactions and global carbon cycles.
My research integrates physical, chemical, and biological measurements from the San Pedro Channel in order to examine the relationships between environmental dynamics, microbial community shifts, and bacterial carbon cycling. I am using this analysis to investigate the necessity and feasibility of incorporating a dynamic bacterial component into ecosystem models.
I am currently accepting graduate students for the Fall of 2015. If you are interested, please contact me at n.levine 'at' usc.edu.
