A new approach to sequence Earth history at high resolution over the past 66 million years

Objective

"One major challenge to be addressed by this proposal is to overcome fundamental obstacles to generate a first high-resolution and continuous fully integrated record of geological events, ages and durations
(a ‘sequence of Earth history’) for the past 66 million years, anchored to the present, to extract properties of Earth’s and solar system orbital motion, and then to apply this time scale to solve first order questions about Earth’s climate system and Earth System sensitivity. The project will bridge the long-standing ‘Eocene tuning gap’, primarily using spectacular new data recovered during Integrated Ocean Drilling Expedition 342 and integrated with a new consistent and integrated approach with existing data that currently only provide time sequences floating in time, not anchored to the present. The proposal will extract astronomical parameters (tidal dissipation, dynamical ellipticity) and verify astronomical models to provide long term amplitude modulation patterns of Earth’s orbital variations (obliquity and short eccentricity) beyond 40 million years before present. It will also search for the fingerprint of chaotic transitions in the solar system that will allow astronomical models to be tested. The improved geologic time scale will then be applied, exploited, and combined with modern Earth System Models of Intermediate Complexity to quantify Earth System sensitivity to orbital forcing during a world of elevated carbon-dioxide concentrations during the ‘greenhouse’ Paleogene. Using novel new pattern matching and recognition algorithms as well as time series analysis methods, the full record of Earth history will be fully integrated and analysed with a consistent and documented workflow. This development will have the ground-breaking potential to take ‘Earth sequencing’ to the next level."
