AUTEC Bathymetric Survey Sites 1 and 2
Abstract
Tracor Marine conducted additional deep and shallow water surveys at platform, the survey at sites 1 and 2 during August 1983. Using the LCM 75 as a survey platform, the survey equipment consisted of a Krupp-Atlas-ElektroniK DESO-20 Fathometer System, an EDO Western Deep Water Bathymetric System, a DECCA Model 540 Trisponder Navigation System and an Autocarta II Data Acquisition System with a remote Left/Right Display Unit and 20 inch DP-3 Plotter. At Site 1 on August 7 20 survey lines were run about a point situated approximately one- half nautical mile north of the seabuoy. At Site 2 on August 8 six survey lines were run approximately one-half nautical mile south of the seabuoy. Eight of the 20 survey lines at Site 1 were rerun. Using Sites 1, 2, 3 and High Cay proved adequate for navigation purposes. Numerous problems occurred with the fathometer systems causing a 1-day delay. At Site 1 on August 7, the winds were typically ten knots from the southeast with waves running two to three feet. On August 8, nearly flat calm sea conditions prevailed. This document presents the procedures used in the survey and the data. Developed 1:1 scale vertical profiles of sounding runs at Sites 1 and 2 are included. Keywords: Atlantic Undersea Test and Evaluation Center; Bathymetric surveys; and Underwater acoustics.
