Heterogeneous reservoirs in the marine carbon cycle
(Massachusetts Institute of Technology, 2014)
Understanding the fate of primary production in the ocean is a challenging task because once produced, organic material is oxidized over timescales which range from minutes, to millions of years. This timescale diversity ...
Transformations of mercury in the marine water column
(Massachusetts Institute of Technology, 2014)
Methylation of mercury (Hg) in the marine water column has been hypothesized to serve as the primary source of the bioaccumulating chemical species monomethylmercury (MMHg) to marine food webs. Despite decades of research ...
An inverse approach to understanding benthic oxygen isotope records from the last deglaciation
(Massachusetts Institute of Technology, 2014)
Observations suggest that during the last deglaciation (roughly 20,000-10,000 years ago) the Earth warmed substantially, global sea level rose approximately 100 meters in response to melting ice sheets and glaciers, and ...
