Projects, Collaborations, Networks
We are involved in projects funded by BMBF, DFG, AWI's strategy fund and other funding sources. Cooperations and collaborations have led to a strong network links in the national and international paleoclimate communities.
From the Last Interglacial to the Anthropocene: Modeling a Complete Glacial Cycle (PalMod)
Understanding climate system dynamics and variability during the last glacial cycle is the main goal of this initiative in which several research institutions and partners are taking part. Specific topics are: i) to identify and quantify the relative contributions of the fundamental processes which determined the Earth’s climate trajectory and variability during the last glacial cycle, ii) to simulate with comprehensive Earth System Models (ESMs) the climate from the peak of the last interglacial (the Eemian warm period) up to the present, including the changes in the spectrum of variability, and iii) to assess possible future climate trajectories beyond this century during the next millennia with sophisticated ESMs tested in such a way.
Paleoclimatic Evolution of the Arctic and Subarctic Oceans Since the Last Glacial Period: Sino-German Pacific-Arctic Experiment” (SiGePAX)
Arctic and Subarctic Regions are most sensitive to climate change, and reversely provide dramatic feedbacks to the global climate. With a focus on discovering paleohydrographic and paleooceanographic evolutions in the Arctic and Northwest Pacific Oceans during the last 20,000 years, we work in this German-Sino cooperation programme funded by the ‘Federal Ministry of Education and Research (BMBF) of the Federal Republic of Germany’, 2014-2016.

REKLIM Regional climate change, Helmholtz Initiative
The long-term goal of REKLIM is to develop fully coupled Earth system models at the regional scale, including the interactions between atmosphere, ocean, cryosphere, biosphere, land surface and soils. These Earth system models together with suitable observational strategies and data analysis techniques will allow describing and assessing past, current and future regional climate change. Topics: "Sea level change and coastal protection" & "Abrupt climate change derived from proxy data".
Regressionsbeziehungen zur Saisonalen Vorhersage an Bundeswasserstraßen (AWI - Bundesanstalt für Gewässerkunde)
Monthly to seasonal prediction of water levels and streamflow, for the German rivers (e.g. Rhine, Elbe, Danube, Weser), based on stable teleconnections with global climate parameters and sea surface temperature.

OC1 "The Ocean in the Earth System" Seasonal to decadal climate variability from oceanographic data, coral records and model simulations, Excellence Cluster Marum
Different processes affect the strength of the large-scale overturning circulation, for example, ventilation of the thermocline and of the deep ocean, and interactions between the subpolar and subtropical gyres. Their relative importance and underlying forcing factors on timescales from 10 to 1000 years will be evaluated, using numerical models, recent observations, and paleodata.
OC3 "The Ocean in the Earth System" High- and low-latitude atmosphere-ocean interactions, Excellence Cluster Marum
Tropical-subtropical climate variability and teleconnections to high latitudes will be quantified at monthly resolution for Holocene and last interglacial key intervals based on a unique network of Asian coral cores in combination with data from observational climatologies, ice-core records, and Earth system models.
Integrated Analysis of Interglacial Climate Dynamics - INTERDYNAMIC
INTERDYNAMIC aims at a better understanding of the climate dynamics and internal variability of warm climate periods, with the goal of using quantitative paleoclimate analyses in view of creating more reliable scenarios for future climate change investigations.

From source to sink - decoding the isotopic fingerprint of the eastern Arctic water cycle (Iso-Arc)
The overall goal of the Iso-Arc project, funded by AWI's Strategy Fund, is a first-time detailed detection and description of the eastern Arctic water cycle, its isotopic composition (H218O, HD16O), and imprint in various climate archives. Arctic vapour measurements will be paired with oceanic and precipitation data, as well as climate simulations enhanced by isotope diagnostics.

CSC Project on climate variability
In this project we aim to reconstruct past climate variabilities by performing model simulations, and further to investigate mechanism feedbacks involving the ocean circulation, the role of sea ice, the effect of ice sheet.
Paleoclimate Modelling Intercomparison Project Phase III PMIP3
We are involved in several projects in the framework of the Paleoclimate Modelling Intercomparison Project Phase III, e.g. Quaternary Interglacials, Pre-Pliocene climates, Last Deglaciation,

PAGES - Past Global Changes
PAGES supports research aimed at understanding the Earth’s past environment in order to make predictions for the future. PAGES is a community of paleoclimate and paleoenvironmental scientists and supporters.
Pliocene Model Intercomparison Project (PlioMIP)
PlioMIP is a coordinated international effort to refine and extend our understanding of the climate of the Pliocene as inferred from proxy-archives and climate modelling. We contribute model simulations to the PlioMIP simulation ensemble and have been involved in the data analysis and the publication of the results in a series of manuscripts that appeared in international peer-reviewed journals.
