中国科学院南海海洋研究所--QC28区块海底浅层剖面和侧扫声呐探测调查与研究-2007年航次海南岛A1区侧扫声呐数据a1-029（走航式测量-EdgeTech2000C）-20071106-20071219

海南岛A1区侧扫声呐数据集，覆盖时间为2007-2008年，覆盖区域为海南岛三亚附近海域5m以深海域，覆盖面积775.37平方公里，测线总长938.88公里，比例尺为1:5万。该数据集分第一航次（2007年）和第二航次（2008年），其中第一航次的侧扫声呐资料是通过EdgeTech2000C侧扫和浅剖二合一系统进行采集的，测量参数根据现场探测情况具体确定；第二航次的侧扫声呐资料是通过EdgeTech 4100P浅水侧扫声呐进行采集的，测量参数也根据现场具体探测情况确定。

Side-scan Sonar Dataset of Area A1, Hainan Island. The dataset covers the period from 2007 to 2008, with the surveyed area being the sea region deeper than 5 meters near Sanya, Hainan Island, with a total coverage area of 775.37 square kilometers. The total length of survey lines is 938.88 kilometers, and the map scale is 1:50000. This dataset is divided into two survey cruises: the first cruise conducted in 2007 and the second cruise conducted in 2008. For the first cruise, the side-scan sonar data were collected using the EdgeTech 2000C combined side-scan and sub-bottom profiler system, and the survey parameters were determined based on on-site detection conditions. For the second cruise, the side-scan sonar data were collected using the EdgeTech 4100P shallow-water side-scan sonar, and the survey parameters were also determined based on specific on-site detection conditions.
