Molecular and isotopic records of the combustion inputs to the environment over the last 250 yrs
(Massachusetts Institute of Technology, 2004)
The most ubiquitous source of polycyclic aromatic hydrocarbons (PAHs) to the environment is incomplete combustion. This study generated a high-resolution historical record of pyrogenic PAH emissions since pre-industrial ...
The marine geochemistry of iron and iron isotopes
(Massachusetts Institute of Technology, 2004)
This thesis addressed questions about the Fe cycle by measuring detailed profiles and transects of Fe species in the ocean and also by exploring the use of a new tracer of Fe, Fe isotopic fractionation. In the subtropical ...
