Project Execution Plan for the Near Shore Survey SOCAL ASW (Southern California Anti-Submarine Warfare) Range

摘要

The Southern California Acoustic Range (SOAR) is designed to provide a 100 sq mi antisubmarine warfare training range in 4500 feet of sea water west of San Clemente Island. SOAR will provide accurate tracking of air, surface and submerged targets. This project plan is a working document that details the mobilization, execution and demobilization of an underwater survey of the near shore area of SOAR. The purpose of the survey is to provide geotechnical and environment data for the shore landing for underwater cables. Survey results will provide (a) a basis for environmental factors required for cable design; (b) geophysical data for cable location; (c) data necessary for the Naval Ocean System Center to support an environmental impact statement, and (d) provide the near shore portion of the total range survey. The survey will be conducted in two parts: (a) a diver cable inspection of two existing cables; and (b) an hydrographic survey of bathymetry, sub-bottom profile, side-scan sonar and current meter data.
