松岛冰川 (PIG) 每年从西南极冰盖 (WAIS) 约 10% 的区域输送 69 立方公里的冰。 PIG 的撤退可能会加速 WAIS 内部的冰排放。卫星测高和干涉测量表明，1992年至1999年间，接地的PIG每年变薄达1.6米，影响了150公里的内陆冰川。这种变薄不能用积累的短期变化来解释，而必须是冰川动力学造成的。
The Pine Island Glacier (PIG) transports 69 cubic kilometers of ice each year from approximately 10% of the West Antarctic Ice Sheet (WAIS). It is possible that a retreat of the PIG may accelerate ice discharge from the WAIS interior. Satellite altimetry and interferometry show that the grounded PIG thinned by up to 1.6 meters per year between 1992 and 1999, affecting 150 kilometers of the inland glacier. The thinning cannot be explained by short-term variability in accumulation and must result from glacier dynamics.
