PALEOCEANOGRAPHY AND PALEOCLIMATOLOGY
Oral examination: 2 questions to assess the knowledge on proxies and the mechanisms and time scales of changes; 1 question related to the changes occurred within one specific time frame, among those shown in class and in the slides, drawing a graph.
Understanding the natural variability in the climate system; knowledge of climatic variations and their causes at different time scales; study of proxies in different archives; knowledge of the main oceanographic processes in the present and in the past.
Bases of Paleoceanography and Paleoclimatology: climate system, chronology, proxies. Climatic variability and climate variations: timescales of changes. Paleoceanographic variations, as reconstructed through proxy data.
The climate system: components, inter-relations, annual and inter-annual variability.
Climatic variations: time scales and control mechanisms at the global scale; the anthropogenic impact.
Chronology: main dating methods in paleoclimatology and paleoceanography. Radiocarbon as a dating method and paleoclimatic-paleoceanographic proxy.
Paleoclimatic proxies: examples and applications in the marine, ice and terrestrial record.
Climatic evolution in the geologic past: early Earth climate states and climate evolution; greenhouse and icehouse states; the Cenozoic mid-house; climate variations and Milankovitch cycles; millennial, centennial and decadal-scale variability in the recent past.
Paleoceanographic applications; climate and sea level; paleocirculation and paleoproductivity; global and Mediterranean (sapropel) anoxic events; salinity crisis; ocean acidification in the present-day and in the paleo-record.
Case studies: analysis, processing and interpretation of paleoclimatic and paleoceanographic data. Analysis and discussion on paleoclimatic and paleoceanographic reconstructions from the recent scientific literature.
