ARAMATE

Overview

The goal of ARAMATE was to investigate the mechanisms of ecosystem variability in the North Atlantic region over the past two thousand years.

This research was developed in the context of climatic reconstructions and PAGES syntheses of the past two thousand years in the region, and enhanced this understanding with results from high resolution (annual or higher) marine and terrestrial proxy archives, historical documents and instrumental records.

The high resolution marine records being developed in the PAGES2K Network project MULTICHRON formed an important source for our research, as did existing terrestrial proxies including tree-rings, lake sediments and speleothem records.

In addition, we identified existing documentary archives of ecosystem variability such as records of seabird populations, fisheries and phytoplankton.

Our aim was to:

(i) identify suitable archives and sources of data that can be used for multiproxy reconstructions of one or more ecosystem or climate variable;

(ii) develop at least one high profile paper reconstructing ecosystem and climate change in the North Atlantic region over a period of up to 2,000 years, as well as other papers covering data-model integration and some of the more spatially and temporally constrained aspects of the system.
