Information
Ziele, Inhalte und Methode der Lehrveranstaltung
This lecture series aims to introduce the basics of how CaCO3 mineral formation in the marine realm is linked to Earth system processes, the carbon cycle, and marine life. The lectures cover four main interrelated themes: (1) the physical and chemical basics underpinning CaCO3 polymorph formation and its expression in the abiotic environment, (2) the geological evidence for an oscillation of CaCO3 polymorphs through time (the aragonite-calcite sea concept), (3) the response of calcifying marine organisms on aragonite-calcite sea conditions, and (4) how the deep-time perspective of the CaCO3 system is relevant to the design geo-engineering approaches to mitigate modern-day climate change.
