The climate system experienced a particularly dynamic period during the last deglaciation (20-10 thousand years before present). It was characterized by abrupt, millennial-scale climate events and substantial, opposing shifts in atmospheric CO2 and ∆14C. The leading hypotheses to explain these transient temperature and carbon signals rely on changes in the rate of Atlantic ocean circulation and deep-ocean carbon storage. The major aim of my PhD project is to investigate these open questions by examining the rate proxies (231Pa/230Th ratio, benthic foraminiferal ∆14C, sortable silt mean grain size) in the sediment record in ...
