Fossil pollen records are well-established indicators of past vegetation changes. The
prevalence of pollen across environmental settings including lakes, wetlands, and marine …

We present a conceptual framework for a new approach to environmental calibration of
planktonic foraminifer census counts. This approach is based on simultaneous application of …

Dinoflagellate cysts are useful for reconstructing upper water conditions. For adequate
reconstructions detailed information is required about the relationship between modern day …

The climate sensitivity of the Community Climate System Model version 3 (CCSM3) is
studied for two past climate forcings, the Last Glacial Maximum (LGM) and the mid …

The importance of reconstructing past environments quantitatively in palaeoecology is
reviewed by showing that many ecological questions asked of palaeoecological data …

Observations from the last decade suggest an important role of sea ice in the global
biogeochemical cycles, promoted by (i) active biological and chemical processes within the …

We present a new version of the standardized Northern Hemisphere “modern” dinoflagellate
cyst (“dinocyst”) database, which includes abundances of 71 taxa at 1968 sites across the …

Sea ice plays an important role in Earth's climate system. The lack of direct indications of
past sea ice coverage, however, means that there is limited knowledge of the sensitivity and …

Sea ice cover extent expressed in terms of mean annual concentration was reconstructed
from the application of the modern analogue technique to dinocyst assemblages. The use of …

The oceans and the atmosphere are the two main reservoirs of greenhouse gases and
latent heat on Earth. These reservoirs interact through the ocean surface, and the dynamics …
