据报道，在不同水深条件下，弹丸在未固结地层上的超高速撞击（1.25-6 km/s）。发现背景大气压力的变化是一个重要的附加参数。从大气注入海水、海底地形的改变、巨浪场的产生及其远离震源的传播等方面讨论了这些探索性实验与小行星大小物体的远洋撞击的关系。
The hypervelocity impact (1.25-6 km/s) of projectiles into water overlying unconsolidated strata is reported for a variety of water depths. Variation of the background atmospheric pressure is found to be an important additional parameter. The relation of these exploratory experiments to pelagic impact of asteroidal-sized objects is discussed from the standpoint of atmospheric injection of sea water, the modification of bottom (benthic) topography, and the generation of a field of mega-amplitude sea waves and their propagation away from the source.
