Tittel

Bridging the gap between the terrestrial and marine paleoclimate reconstructions in the North Atlantic realm (PALEOBRIDGE)

Populærvitenskapelig sammendrag

This project is dedicated to the assessment and extension of two state-of-the-art climate field reconstruction (CFR) techniques, applied using terrestrial and marine proxies to construct ensembles of spatially seamless surface temperature field reconstructions in both terrestrial and marine domains in the North Atlantic realm covering the past 2000 years. Focusing on the North Atlantic domain is conditioned by an overall importance of the region for influencing the climate on the global scale. The reconstruction products are used to investigate the mechanisms and forcings of past marine north Atlantic climate on the wider climate variability over Europe. 

 

The two CFR techniques under investigation are "BARCAST" (the Bayesian Algorithm for Reconstructing Climate Anomalies in Space and Time) and the proxy surrogate reconstruction method. The model assumptions of the BARCAST CFR technique represent the most important criticality of this project, since the existing methodology so far does not take different spatiotemporal covariance structures into account. The technique will be updated and tested before usage, and the alternative proxy surrogate reconstruction method will be used regardless of outcome. A successful implementation of the project is therefore secured, and the proposed reconstruction(s) are expected to be of interest for the wider climate community. Having the oceanic and terrestrial domains integrated in the framework of the project will provide means for the analysis of past changes in marine to terrestrial teleconnections in the North Atlantic realm, as well as the assessment and improvements of existing seasonal reconstructions of major climate indices, e.g. the North Atlantic Oscillation and the Atlantic Multidecadal Oscillation for the last 2000 years.
