In the Isotope Laboratory, stable isotopes of carbon, nitrogen, oxygen, and hydrogen are investigated by determining the ratio of individual isotopes (atoms of one element whose nuclei contain different numbers of neutrons) in the sample material. The isotopic composition of the sample allows conclusions about, for instance, the prevailing temperature and precipitation regime when the material was formed. In addition to paleoclimatology, stable isotopes are also utilized in geological, …

The Laboratory for Dendroclimatology aims to reconstruct the temporal and spatial variability of the climate of the past utilizing multi-parameter tree ring analysis and to assess and verify the causes of climate change and its impact on woody plants.

The following tasks are covered:

• quantitative analysis of the climate-signal transfer from atmosphere through soil and leaf into the wood of tree rings (Monitoring, calibration and verification of tree ring parameters vs. instrumental …

The Laboratory for Earth Magnetism in Time and Space deals with magnetostratigraphic dating of paleoclimate archive sand the reconstruction of geomagnetic field variation in the geological past. Therefore, intensity and directions of sedimentary magnetizations are determined. Further, magnetic minerals are characterized by their physical properties, such as coercivity, Curie temperature, grain size, and concentration, as well as by their chemical composition and preservation status.

The laboratory for microscopy focuses on the specific requirements of microfacies analysis of lake sediments, but also offers a wide range of possibilities for other applications. Sedimentological, petrographic and microfacies analyses on all kinds of covered and uncovered thin sections and polished sections with transmitted and incident light are performed.

The micropaleontology lab is equipped to conduct morphological analyses including extraction, microscopic preparation and taxonomic investigations of microfossils from terrestrial plants e.g. pollen grains and aquatic organisms e.g. diatom valves and chironomids from lake sediment archives or permafrost deposits. Microfossil analyses are used to investigate spatial and temporal changes and environmental reconstructions in Arctic terrestrial ecosystems.
The extraction of microfossil remains …

The palaeogenetics lab is a part of the larger molecular genetic facility specialized to analyse ancient sedimentary DNA and is placed in a separate building apart from the modern and recent environmental lab and Post-PCR areas. In the palaeogenetics lab we analyse ancient DNA from sediment cores (lakes or marine archives) or permafrost deposits.
We apply DNA metabarcoding and metagenomics (shotgun and hybridisation capture) to investigate spatial and temporal biodiversity with the aim of …

The core of the laboratory is a Raman micro-spectrometer. The spectrometer is equipped with a cryostat serving as a planetary simulation chamber which permits simulation of environmental conditions on planetary surfaces, namely pressure (10⁻⁶ hPa – 1000 hPa), atmospheric constituents, and temperature (4 K – 500 K). The laboratory is also equipped with preparation facilities for analog materials. The samples which are analyzed in the laboratory range from minerals, Martian analog material, …
