流入前拉森B冰架的冰川以不同的方式对2002年3月的冰架解体做出了反应。应对措施包括延长前线后退、先进后退、保持稳定的前线阵地。退缩的冰川最初加速并急剧变薄，尽管此后至少有一座大型冰川的变化速度有所下降。在这里，在潮水冰川过程的背景下记录和讨论了应对模式。在拉森B海湾周围观察到的不同反应表明，在考虑出口冰川对其下游端扰动的反应时，三维地理环境的重要性。(C)2008爱思唯尔B.V.保留所有权利。
Glaciers that flowed into the former Larsen B ice shelf have responded to its March 2002 disintegration in different ways. The responses include prolonged front retreat, advance followed by retreat, and maintenance of a stable front position. Retreating glaciers initially accelerated and thinned dramatically, although the rate of change has since declined on at least one large glacier. Here, response patterns are documented and discussed in the context of tidewater glacier processes. The different responses observed around the Larsen B embayment demonstrate the importance of the three-dimensional, geographic setting when considering the response of outlet glaciers to perturbations at their downstream ends.
