This session will address the reconstruction of past ocean and climate variability on seasonal to multicentennial timescales from high-resolution marine archives. Such archives include laminated sediments and deposits from high accumulation sites, as well as annually banded shallow-water corals, deep-water corals, sclerosponges, and bivalves. Recent advances in the isotopic and geochemical analyses of individual foraminifera can also contribute to paleoceanographic reconstructions on these timescales.

Topics of interest include the natural range of seasonality and interannual to multicentennial climate variability of the coupled ocean-atmosphere system, expressed in a variety of climate modes such as the El Nino-Southern Oscillation (ENSO), the Arctic Oscillation/North Atlantic Oscillation (AO/NAO), the Atlantic Multidecadal Oscillation (AMO), and the monsoonal systems, during past periods including those with boundary conditions different from today. Furthermore, changes in the ocean circulation and surface and deeper-ocean characteristics on these timescales will be addressed.

Contributions are welcome on the application of established and new proxies and their statistical interpretation.

Presentations on the combination of proxy-based reconstructions with state-of-the-art climate model simulations are encouraged, in order to provide a better process-orientated understanding of ocean and climate dynamics on these timescales.
