对南极冰芯中包含的球体的研究，提高了这些独特的外星粒子的大小分布和年质量沉积量的值。以前对每年从空中和海洋沉积物收集的沉淀量的估计从每年8公吨到2,000,000公吨不等。本研究得出的数字是每年18.4万公吨。
A study of spherules contained in antarctic ice cores leads to improved values for the size distribution and annual mass deposit of these distinctive extraterrestrial particles. Previous estimates of the annual deposit based on collections from air and from ocean sediments have varied from 8 metric tons to 2,000,000 metric tons per year. The figure derived from the present study is 184,000 metric tons per year.
