Constraining circulation changes through the last deglaciation with deep-sea coral radiocarbon and sedimentary ²³¹Pa/²³⁰Th
(Massachusetts Institute of Technology, 2012)
Radioactive isotopes can be used in paleoceanography both for dating samples and as tracers of ocean processes. Here I use radiocarbon and uranium series isotopes to investigate the ocean's role in climate change over the ...
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 ...
Little Ice Age climate in the western tropical Atlantic inferred from coral geochemical proxies
(Massachusetts Institute of Technology, 2016)
Paleoclimate archives place the short instrumental record of climate variability in a longer temporal context and allow better understanding of the rate, nature and extent by which anthropogenic warming will impact natural ...
