Roles of Oceanography and Orbital Forcing in Greenhouse Climates

Explore the intricate relationship between oceanography and orbital forcing in greenhouse climates through this comprehensive lecture. Delve into the strong influence of orbital parameters on environmental conditions during warmer periods, resulting in rhythmic sedimentary sequences. Examine how these successions reveal past climate pacing and provide detailed time scales for climate perturbations. Investigate the crucial role of ocean circulation in distributing heat and nutrients during greenhouse climates. Analyze the impact of geography, such as the opening of gateways, on ocean currents in warmer climates. Study various topics including the end of the Cretaceous period, obliquity, carbon isotope data, volcanism, relative timing, mercury proxies, and oceanography. Gain insights from numerous scientific references and research papers that support the lecture's content, covering subjects like large igneous province volcanism, cyclostratigraphy, astronomical tuning, and the intensification of Atlantic overturning circulation.
