Abstract : This document contains a section of environmental parameters that is part of a larger Mediterranean Sea area acoustic assessment compiled under the auspices of the ASW Environmental Acoustics Support Project Office. Its contents reflect an environmental description of the geology, oceanography, sound speed variability, and currents in selected areas of the Mediterranean Sea. The geology section addresses the physiography, sediment thickness, dispositional processes, volcanism, and seismicity of each region. In many areas, the oceanographic section represents a significant update, since it includes available documentation resulting from two large-scale multinational field investigations: the Physical Oceanography of the Eastern Mediterranean and the Western Mediterranean Circulation Experiment. The sound speed section, based on the Master Oceanographic Observation Data Set, is a tailored analysis of both temporal variability and profile gradient changes. This analysis results in the selection of the closest actual sound speed profiles to the arithmetic average. The section on currents focuses on the availability and description of abyssal current data and includes results from the Naval Oceanographic and Atmospheric Research Laboratory Layered Circulation Model.
