Objectives:
|
Establish late Neogene–Quaternary intercalibration of geomagnetic paleointensity, isotope stratigraphies, and regional environmental stratigraphies, and in so doing develop a millennial-scale stratigraphic template.
Such a template is required for understanding the relative phasing of atmospheric, cryospheric, and oceanic changes that are central to our understanding of the mechanisms of global climate change on orbital to millennial timescales.
