Objective<\/strong><\/p>\r\n\r\n\r\n\r\n

The aim of this lecture is to lay the foundations for the role of the marine carbon cycle in controlling climate on a global scale by regulating the partial pressure of atmospheric CO2<\/sub>.\r\nThe course covers the carbon cycle in the surface ocean and water column, the calcium carbonate cycle, glacial and interglacial fluctuations in atmospheric CO2<\/sub> during the Holocene, and anthropogenic CO2<\/sub> perturbation (methods for tracing anthropogenic carbon in the ocean).<\/p>\r\n\r\n\r\n

Lectures<\/strong><\/p>\r\n\r\n\r\n\r\n

1. The carbon cycle in the surface ocean<\/strong>: what factors control pCO2 in the surface ocean (dissolved mineral carbon chemistry – Revelle factor, mean annual distribution – physical and biological control processes, seasonal variability – subtropical gyres, North Atlantic, North Pacific), case study (deep-sea upwelling).<\/p>\r\n\r\n\r\n\r\n

2. The carbon cycle in the water column<\/strong> (notion of pump, biological pumps, solubility or gas exchange pump, model results),<\/p>\r\n\r\n\r\n\r\n

3. The calcium carbonate cycle<\/strong> (formation, processes in the water column – CaCO3 solubility, saturation state, carbonate distribution, dissolution in the water column -, impact of ocean acidification),<\/p>\r\n\r\n\r\n\r\n

4. Anthropogenic CO2<\/sub> perturbation<\/strong> (the greenhouse effect, glacial-interglacial fluctuations in atmospheric CO2<\/sub> during the Holocene, global warming, evidence of anthropogenic perturbation). Thermodynamic and kinetic constraints on CO2<\/sub> transfer between atmosphere and ocean. Penetration of anthropogenic CO2<\/sub> into the ocean (direct estimates, methods for tracing anthropogenic carbon in the ocean – TROCA method, C* method, Chen and Millero method -, current and future ocean absorption capacity).<\/p>\r\n\r\n\r\n\r\n
