Profile

Our main objective is to elucidate the two major cycles (water and heat) in the complex Arctic landscape system at scales from metres to kilometres (meso-scale). The goal is to close the gap between our small-scale process understanding and the large scale that is accessible to satellite remote sensing.

We work intensively at two Arctic sites in Siberia (Lena Delta) and Spitsbergen (Ny-Alesund). Through international cooperation, additional sites in Alaska and Canada complement the circumpolar analysis. The Arctic ecosystems range from warm, maritime conditions with low above ground biomass (Spitsbergen), over medium, continental climate with high above ground biomass (North Slope, Alaska) towards extreme cold, dry but ice rich permafrost conditions with medium biomass (Lena Delta, Siberia).

By studying these different locations, we hope to gain an understanding of how changes in annual and inter-annual heat and water processes and potentially offset the balance and stability of the Arctic climate system.

In particular, we focus on:

  • Establishing spatial and temporal linkages between water and energy fluxes at the plot and landscape scales of different permafrost affected ecosystems;
  • Developing a process-oriented model for the typical Arctic permafrost system to predict subsurface processes (soil water and heat);
  • Use of innovative aerial imaging methods, including telescopic rods, ballons, kites and drones;
  • Instrumentation on soil thermal and hydrologic dynamic and micrometeorology with spatially distributed measurements; and
  • Long term monitoring of data.

The research is based at the Alfred Wegener Institute for Polar and Marine Research, Research Unit Potsdam and networked with the Faculty of Chemistry and Geosciences and Institute of Environmental Physics, University of Heidelberg.

field sites and observatories

Depending on our partners and the research project our group is working at different places in the Arctic.

Since many years we are responsible for research stations on Svalbard, Norway and in the Lena Delta, Sibiria.

The exact location, pictures and more information about the sites can be found here.

-->

outreach and education

Our team is actively involved in many education and outreach activities, to make the research results transparent and easy to understand for everybody.

During the winter term Julia Boike is giving the lecture "Polar Geography" at the Humboldt University in Berlin. 

Therfore we go at schools or supporting the 'Kinderuniversität'.

Other examples are the participation in the fairplanet discussion about frozen ground, the contribution to the article: 'Siberia's melting permafrost fuels climate change' or the publication of the article 'In the Far North. When the Climate Desert Thaws' by Inga Beck in the research magazine Ruperto Carola of the University of Heidelberg.

Please find more about our recent activities at 'news'.
