Creator:: Muglia, Juan
Abstract:: During the Last Glacial Maximum (LGM, ∼ 21 ky before present) the atmospheric CO2 concentration was about 100 ppm lower than its pre-industrial (PI)value. The missing carbon from the atmosphere must have been stored in thedeep ocean during this period, but the mechanisms driving such re-distribution ofthe carbon cycle are...

Abstract:: We present a new nitrogen isotope model incorporated into the three-dimensional ocean component of a global Earth System Climate Model designed for millennial timescale simulations. The model includes prognostic tracers for the stable nitrogen isotopes, ¹⁴N and ¹⁵N, in the nitrate (NO₃ˉ), phytoplankton, zooplankton, and detritus variables of the marine...

Creator:: Praetorius, Summer Kate
Abstract:: Paleoclimate archives have revealed abrupt climate events that are superimposed on more gradual climate changes throughout the last glacial and deglacial periods. The underlying causes of such rapid climate changes are still poorly understood, but the strong expression of these events in northern hemisphere records likely points to climatic mechanisms...

Creator:: Jayawickrama, Clare
Abstract:: Ocean deoxygenation is predicted to increase in severity over the next few decades, posing a threat to marine life and fishing economies. Improved predictions of ocean deoxygenation depend on a better understanding of the biogeochemical mechanisms that underly this process. Within the realm of biogeochemical mechanisms, this project specifically investigated...

Abstract:: If a scientist can predict the weather (poorly) Why cannot he predict fish yields (yet more poorly)? – a clerihew by Chris Corkett. Recent long term historical studies of commercial fisheries have pointed to a well established pattern of overfishing. Under the principle of transference – what is true in...

Creator:: Du, Jianghui
Abstract:: The Global Overturning Circulation (GOC) is a major component of the global climate system. Understanding its behavior is pertinent to our prediction of climate change in the future. The lack of long-term observations of GOC in the modern instrumental era necessitates studies of GOC using paleoceanographic records. Of great interest...
