A Geoacoustic Model for Fine-Grained, Unconsolidated Calcareous Sediments (ARSRP Natural Laboratory)
2006
Bowles, Frederick A.
This report presents a geoacoustic model that is broadly applicable to deep ocean areas that are covered with soft, finegrained, predominantly calcareous sediment. The model is based on a compilation and assessment of sediment (geoacoustic) properties deemed important as input parameters to acoustic field models. Physical properties measurements (compressional wave velocity, shear wave velocity, density, porosity) extracted from Deep Sea Drilling Project and Ocean Drilling Program Initial Reports provide the bulk of the accumulated data. Attenuation data and additional shear wave data were obtained from other sources. The data are presented as: (1) statistical summaries; (2) cross-plots illustrating the relationships between properties; and (3) regression equations. Empirically derived relationships commonly used to prepare geoacoustic models are not employed by this model. A discussion is presented in order to document the reasoning and, ultimately, the choices made in constructing the model. Geoacoustics, Geologic models, Seafloor, Sediments.
