AUTEC Shallow Water Bathymetric Survey Sites 1 and 2
Abstract
As a follow-on to deep water bathymetric surveys conducted at Andros Island, Bahamas (AUTEC Sites 1, 2, and 7) during May-June 1983, precision shallow water surveys were conducted at Sites 1 and 2 during July 1983. Using the LCM 75 as a survey platform, the survey equipment consisted of a Krupp- Atlas-Elektronik DES0-20 Fathometer 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. Survey work at site 1 on July 4 consisted of positioning the 12 meter and 25/30 meter contours from High Cay to Calabash Bay, a distance of approximately 16 nautical miles. Using sites 1 and 2 for navigation proved inadequate close to shore and north of site 1. A third trisponder station was established on High Cay. Three areas of interest observed in the July 4 data, were developed at 50 meter crossline intervals at July 5. The July 5 operations also included development runs at Site 2, Tracks 3 and 8, which were originally surveyed on May 31. On July 6 development was completed at Site 2 areas. Throughout this survey, the winds were typically 15 knots from the southeast with waves running three feet. Survey deliverables included: Bathymetric Analog Records; Data Acquisition Record Printouts; Sounding Sheets at 1:5,000 scale for each area surveyed; Vessel Track Sheets at 1:5,000 scale for each area surveyed. Sounding Sheets at 1:1,080 scale for selected areas of interest; 1:1 scale Vertical Profiles of various sounding runs at Sites 1 and 2.
