Cyclostratigraphy and Astronomical Forcing of Past Climates
Cyclostratigraphy and Astronomical Forcing of Past Climates
Session ID#: 77585
Session Description:
The astronomical theory of climate change, pioneered by Milankovitch, connects variations in Earth’s orbit to glacial-interglacial cycles. As we continue to develop high-resolution globally distributed records, questions emerge concerning the pacing of various features of the climate system. Studies of the astronomical theory have led to established tools such as cyclostratigraphy and astrochronology allowing high-resolution geological time scale and a better understanding of mechanisms for past climate change. Their integration with paleoceanography provides important constraints on Earth’s paleoclimate and carbon cycle dynamics under different boundary conditions. Comparing cyclostratigraphic data with astronomical models also provides valuable insight into the chaotic dynamical nature of the Solar System in the remote past. This session focuses on cyclostratigraphic techniques, bringing together proxy-based, theoretical and/or modeling studies about global and regional climate responses to astronomical forcing at different time scales in the geologic record.
