Ba isotopes

Freya Hemsing and Maksym Gachkivskyi have prepared the first Heidelberg Ba-isotope double spike using material from Oak Ridge National Laboratory

Geochimica Cosmochimica Acta

Jens Fohlmeister and the team working on caves of the Swiss Alp have shown how calcite and aragonite precipitation fractionates stable isotopes which can now be corrected for when time series of stalagmites present such features along their growth axes.

Journal of Quaternary Science

Fabio Hering and the Chan Hole cave (Mexico) research team have demonstrated evidence of humans occupation for more than 1200 years during the early and middle Holocene, with interruptions caused by global sea level rise and cave flooding.

Earth & Planet. Sci. Lett.

Freya Hemsing has published a very first assessment of the Ba-isotope fractionation between seawater and cold-water corals, which demonstrates its potential as possible paleo-nutrient type tracer.

Physics of Environmental Archives

Physics of Environmental Archives explores the climate messages left in various geological sedimentary archives such as corals, speleothems, calcareous tufa and marine sediments. We are interested in conducting high precision U-series and radiocarbon dating (the later in close cooperation with the Curt Engelhorn Centre for Archeometry ) and we focus on the cycles of trace elements and isotopes which serve to fingerprint the climate information we intent to retrieve.
