Abstract

An ice core from Berkner Island, a coastal site on the Weddell Sea facing the Southern Atlantic Ocean, provides
a new climate record and further insights into north-south teleconnection. Isotopic measurements (dD and d18O) show two distinct peaks during MIS 3 corresponding to the AIM 8 and AIM 12 climate events. High resolution 15N measurements of air occluded in bubbles were carried out across these two events and changes of +0.07 per mil d15N were observed. The
