Laboratory of Chronology

We conduct research in collaboration with nearly all universities and sectoral research institutes in Finland. Our research topics include, among others, past climates, volcanic winters, human population history, solar superstorms, the last mammoths, African termites, and the soil carbon cycle. We also promote the transition to a fossil-free economy.  

Our laboratory is located on the Kumpula campus of the University of Helsinki, in the Physicum building at Gustaf Hällström Street 2. The campus and its vicinity are easily accessible by bus or tram. At the Kumpula campus, we collaborate especially with the Accelerator Laboratory on radiocarbon determinations.

Our measurement methods are state-of-the-art: we use Accelerator Mass Spectrometry (AMS) for radiocarbon determinations, Isotope Ratio Mass Spectrometry (IRMS) for stable isotope analyses, and Optically Stimulated Luminescence (OSL) methods for luminescence analyses. Our equipment includes devices for sample preparation and actual analyses, as detailed in the equipment list below.

Additionally, we maintain publicly accessible databases of the data produced (www.oasisnorth.org). Our expertise also covers Bayesian chronological modeling of dating data and dietary modeling based on stable isotope data. Furthermore, we teach our methods in the educational programs at the University of Helsinki.

Our methods and expertise can be utilized throughout the entire cycles of the elements being studied. We are eager to support and develop new interdisciplinary projects, especially those that combine different measurement techniques, as research challenges are multidimensional. Please feel free to contact us so we can brainstorm new projects for your needs.
