2000年，在南极洲的罗斯海和威德尔海见证了几座巨大的冰山的崩解，其中包括可能是迄今为止观测到的最大的冰山bl5的崩解。在这里，我们展示的卫星图像记录了2000年3月下旬的冰裂，以及导致b - 1b - 5从罗斯冰架分离的前兆事件。这些图像表明，冰架上的大裂缝网络在崩裂前的十年里的演变控制了崩裂的时间和B-15的巨大尺寸。究竟是什么控制着这种进化，仍然是个谜。
Abstract The year 2000 has witnessed the calving of several remarkably large icebergs in the Ross and Weddell seas of Antarctica, including the calving of B-l 5, possibly the largest iceberg yet to be observed. Here we present satellite imagery that records the calving, and precursor events leading up to the detachment of B-l 5 from the Ross Ice Shelf in late March 2000. These images suggest that the evolution of a network of large rifts on the ice shelf over the decade prior to calving has controlled both the time of calving and the giant size of B-15. What controls this evolution in turn remains a mystery.
