Bottom Loss Measurements in the Eastern Pacific Ocean

Abstract

Low frequency acoustic bottom loss measurements were conducted from aircraft over a broad Northeastern Pacific region, using sonobuoys and explosives. Geologic descriptions of the region typify it as being somewhat uniformly blanketed by pelagic clays less than 100 m thick. Bottom loss at the 20 stations visited, however, showed considerable variation. Individual station results are presented with supporting data. In addition, bottom loss data acquired at several closely grouped stations north of Hawaii are compared to results of measurements conducted in the same region by shipboard techniques during the PARKA II-A exercise.
