摘要

在2011年秋季,我们在阿尔卑斯东部的Alto dell 'Ortles冰川(3859米,南蒂罗尔,意大利)的一个新的钻探地点提取了第一批钻到基岩上的冰芯。直接冰芯观测和冰川温度测量提供了伴随存在浅温带冰层和深冷冰层(低于压力熔点的冰)的证据。据我们所知,这是第一次在东欧阿尔卑斯山脉的冰川中观察到冰冷的冰。这些冰层可能代表了公元1980年以前寒冷气候的独特遗迹。我们得出的结论是,奥尔托尔冰川现在正从寒冷状态转变为温带状态。该冰川中冷冰层的出现,增加了在恢复的冰芯中充分保存气候和环境记录的可能性。

DISCOVERY OF COLD ICE IN A NEW DRILLING SITE IN THE EASTERN EUROPEAN ALPS
During autumn 2011 we extracted the first ice cores drilled to bedrock in the eastern European Alps from a new drilling site on the glacier Alto dell’Ortles (3859 m, South Tyrol, Italy). Direct ice core observations and englacial temperature measurements provide evidence of the concomitant presence of shallow temperate firn and deep cold ice layers (ice below the pressure melting point). To the best of our knowledge, this is the first cold ice observed within a glacier of the eastern European Alps. These ice layers probably represent a unique remnant from the colder climate occurring before ~1980 AD. We conclude that the glacier Alto dell’Ortles is now changing from a cold to a temperate state. The occurrence of cold ice layers in this glacier enhances the probability that a climatic and environmental record is fully preserved in the recovered ice cores.
