An investigation of basin-scale controls on upper ocean export and remineralization
(Massachusetts Institute of Technology, 2018)
The biological carbon pump (BCP) helps to moderate atmospheric carbon dioxide levels by bringing carbon to the deep ocean, where it can be sequestered on timescales of centuries to millennia. Climate change is predicted ...
The marine biogeochemistry of chromium isotopes
(Massachusetts Institute of Technology, 2018)
In the ocean, chromium (Cr) is a redox-sensitive trace metal. The reduction of Cr(VI) to Cr(III) occurs in oxygen deficient zones (ODZs), and Cr reduction in general has been identified as a significant Cr isotope fractionation ...
