Résumé en anglais

Among microfossils currently extracted from Cenozoic sediments to reconstruct past environments are planktic foraminifers. These small calcareous organisms are furthermore probably ranked first in this set of tools when considering Paleoceanography, a science that has grown up proportionally to their use since now more than half a century. Planktonic foraminifera (PF) actually constitute the key material for paleoceanographers as a basic tool for stratigraphical and paleoecological reconstructions, both often based on coupled geochemical and micropaleontological approaches. Since the late ninety’s, the modern calibration of the PF proxy has taken growing importance, challenging the principle of uniformitarianism, especially in response to questions introduced by the molecular biology. This calibration can rely on two approaches: the first implies repetitive surveys of modern populations (throughout plankton tows or sediment traps) and the other one directly targets the analysis of recently fossilized populations in the topmost oceanic sediments in order to implement regional databases and develop the statistical approach of transfer functions sensu lato. This paper reviews the strengths and weaknesses of the latter approach, focusing on the North Atlantic Ocean (and its border seas), which up to now counts the largest existing set of data concerning planktonic foraminifera population.< Réduire
