研究了北冰洋、波弗特海、北冰洋和近岸地区的弹性波传播。冰层厚度从0.1米到2.1米不等，水深从1.5米到3800米不等。根据测得的纵波速度、横波速度和密度求出了弹性常数的值。详细研究了频散弯曲波和空气耦合弯曲波，并将其用于冰层厚度的推算。探测到了速度为1700米/秒的高频到达，其理论依据尚未确定。
Elastic wave propagation was studied in the Arctic ice pack, on the Beaufort Sea, the Arctic Ocean, and at near-shore locations. Ice thicknesses varied from 0.1 to 2.1 meters and water depths from 1 ½ to 3800 meters. Values of the elastic constants were derived from the measured velocities of the longitudinal and shear waves and the density. Dispersive flexural waves and air-coupled flexural waves were examined in detail and were used to deduce ice thicknesses. A high-frequency arrival with a velocity of 1700 meters/second was detected, the theoretical justification of which is not yet determined.
