Adi Torfstein is an Associate Professor at the Institute of Earth Sciences in the Hebrew University of Jerusalem and a resident scientist at the Interuniversity Institute of Marine Sciences of Eilat. He is also head of the Oceanography program at HUJI.
Research fields: Geochemistry, Oceanography, Paleoclimate
Main interests: Isotope and trace element geochemistry of seawater and sediments, U-decay series, seawater biogeochemistry, dust and sediment provenance, paleoclimate, paleoceanography, geochronology.
Our research focuses on the reconstruction of past climate changes through the investigation of geochemical and sedimentary processes in marine and lacustrine archives. We are also interested in the signal transfer between the modern atmosphere and oceans to the geological record. Accordingly, our research combines between time series of modern terrigenous fluxes and biogeochemical cycles in the oceans (see the REDMAST project), and late Quaternary marine and lacustrine records.
Below is a list of current and recent research projects in our group, and you can find some more pictures from our field and lab work in the Gallery.
