摘要

摘要为了了解威德尔海沿岸地区冰盖的长期气候和冰川学演化，英国南极调查局在伯克纳岛、詹姆斯·罗斯岛和弗莱彻海角进行了一系列成功的冰芯钻探项目。一个名为WACSWAIN的新项目试图通过在该地区另外两次冰上升的基岩上进一步钻探来增加这一知识。在一个单季项目中，在Skytrain ice Rise 651米的基岩上，使用充满流体的钻孔中的冰芯钻将冰芯回收。在第二季中，使用快速进入钻机在谢尔曼岛的一个干燥钻孔中回收了323米的冰块，但未能到达预计深度428米的基岩。

Ice drilling on Skytrain Ice Rise and Sherman Island, Antarctica

Abstract To understand the long-term climate and glaciological evolution of the ice sheet in the region bordering the Weddell Sea, the British Antarctic Survey has undertaken a series of successful ice core projects drilling to bedrock on Berkner Island, James Ross Island and the Fletcher Promontory. A new project, WACSWAIN, seeks to increase this knowledge by further drilling to bedrock on two further ice rises in this region. In a single-season project, an ice core was recovered to bedrock at 651 m on Skytrain Ice Rise using an ice core drill in a fluid-filled borehole. In a second season, a rapid access drill was used to recover ice chips to 323 m on Sherman Island in a dry borehole, though failing to reach the bedrock which was at an estimated depth of 428 m.

期刊介绍： Annals of Glaciology publishes original scientific articles and letters in selected aspects of glaciology-the study of ice. Each issue of the Annals is thematic, focussing on a specific subject. The Council of the International Glaciological Society welcomes proposals for thematic issues from the glaciological community. Once a theme is approved, the Council appoints an Associate Chief Editor and a team of Scientific Editors to handle the submission, peer review and publication of papers.
