Abstract

A high-resolution data base was created by the Naval Research Laboratory for the Naval Oceanographic Office in support of AntiSubmarine Warfare and Mine Countermeasures planning and operations for the littoral region surrounding Taiwan. The complex geology of the region is described on a physiographic province map with a complete explanation. The surficial sediment types, documented in a series of surficial sediment maps, were used in conjunction with a knowledge of basement type and stratigraphic information, as a basis for creating a series of 128 geoacoustic models. These models, which comprise a geoacoustic data base, were validated by comparing acoustic transmission loss calculations with measured data in the Bashi Channel. Finally, mine burial predictions based on surficial sediment information were compared with predictions based on down-core sediment properties measured in the upper 2 m. The results were significantly different, indicating that wherever possible, sediment data as a function of depth should be utilized to obtain reliable mine burial predictions.
