Earth System Dynamics, Ocean Circulation and Biogeochemical cycling
My research looks at the role of the ocean circulation in past climate change, including in particular its impact on the hydrological- and biogeochemical cycles. Ultimately this work aims to provide a geological perspective on the climate system and its dynamics on relatively short time-scales (10-104 yrs); time-scales that are relevant to past and future human activities. I use a range of geochemical, sedimentological and micropalaeontological methods to infer past hydrographic changes (including stable and radiogenic isotope and trace element analyses). Ongoing research projects include investigations of: 1) the causes and consequences of abrupt oceanographic and climate change on the southern Iberian Margin during the late Pleistocene; 2) the deep ocean’s temperature, oxygenation and carbonate ion response to rapid climate change during MIS 3 and MIS 6 (and its link to atmospheric CO2); 3) laser-ablation analysis techniques to understand rare earth element and redox sensitive element cycling; 4) the role of the ocean circulation in glacial-interglacial CO2 change and the evolution of the marine radiocarbon inventory across the last deglaciation; and 5) the hydraulics of the last Lake Agassiz ‘super-flood’.
