Detangling Flow Regimes and Paleoclimate in the Deepest Section of the EDML Ice Core using U-series Ages.

In this work, we implemented new physical and geochemical techniques to test a novel method for determining the age of ice in the Dronning Maudland ice core in coastal Antarctica. In collaboration with a private company, we installed a nano scale, a device that provides accurate and precise measurements of the reactive surface area of dust in ice cores.

In order to confirm our analytical precision as we set-up the method in a new laboratory we tested a series of non-ice core samples, which resulted in a publication on modern dust. Combining the former techniques with the latter, we are able to calculate the age of ice. Our results indicate that this technique will be broadly applicable to ice samples of unknown age across Antarctica.
