Here you will find research projects at the Laboratory for Isotope Geology.

Per Andersson

• How water-sediment interactions control micronutrient and isotopic tracer distributions on the Siberian Shelves of the Arctic Ocean. Read more: ISSS2008
• Silicon isotope-based reconstruction of the silicon cycle and diatom production in the Baltic Sea; Implications for climate change and eutrophication.
• Apportionment of natural versus anthropogenic sources of halocarbons depleting Arctic ozone: Novel applications of powerful halocarbon-specific analysis of stable chlorine and bromine isotopes and radioactive carbon (carbon-14).
• Iron isotopes in continental shelf sediments: a key to understand the biogeochemical cycling of iron in the marine environment.
• Take part in GEOTRACES which is an international study of the global marine bi og eochemical cycles of trace elements and their isotopes. The mission is: To identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions.
