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-2008年航次海南岛A1区侧扫声呐数据a1-029（走航式测量-EdgeTech 4100P）-20080519-20080625

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 for Area A1, Hainan Island. With a coverage period spanning 2007 to 2008, this dataset covers sea areas deeper than 5 meters in the vicinity of Sanya, Hainan Island, with a total coverage area of 775.37 square kilometers, a total survey line length of 938.88 kilometers, and a scale of 1:50,000. This dataset is divided into two cruise surveys: the first cruise conducted in 2007 and the second cruise conducted in 2008. The side-scan sonar data from the 2007 cruise was collected using the EdgeTech 2000C combined side-scan and sub-bottom profiler system, with survey parameters determined based on on-site detection conditions. The side-scan sonar data from the 2008 cruise was collected using the EdgeTech 4100P shallow-water side-scan sonar, with its survey parameters also determined based on specific on-site detection conditions.
