Currently there is a scarcity of paleo-records related to the North Atlantic Oscillation (NAO), particularly in East-Central Europe (ECE). Here we report δ<sup>15</sup>N analysis of guano from a cave in NW Romania with the intent of reconstructing past variation in ECE hydroclimate and examine NAO impacts on winter precipitation. We argue that the δ<sup>15</sup>N values of guano indicate that the nitrogen cycle is hydrologically controlled and the δ<sup>15</sup>N values likely reflect winter pre ...[more]
