2015-2016南海冷泉数据集（ROV旁扫浅剖）

在该航次中，ROV搭载深水地球物理探测系统（包括深水多波束，深水侧扫声纳系统和深水浅地层剖面系统）进行水下高分辨率地形地貌以及地层内部结构数据的采集，利用PHINS定位，获得高精度的定位数据。获得了两个研究区高精度的多波束水深数据、侧扫声纳图像以及浅底层剖面数据，测线距离合计55km，覆盖面积约为4km2。科考船到达工作区完成多波束地形地貌、重力、磁力、浅地层结构联合测量，所上传数据为浅地层剖面数据和旁扫声纳数据。

During this cruise, the ROV, equipped with a deep-water geophysical exploration system comprising a deep-water multibeam echosounder, deep-water side-scan sonar system, and deep-water shallow sub-bottom profiler, was used to collect high-resolution underwater topographic, geomorphic and internal stratigraphic structure data, with high-precision positioning data acquired via the PHINS positioning system. High-precision multibeam bathymetric data, side-scan sonar images, and shallow sub-bottom profile data were obtained for the two study areas, with the total length of the survey lines reaching 55 km and a coverage area of approximately 4 km². The research vessel arrived at the work area to conduct a combined survey covering multibeam topographic and geomorphic mapping, gravity, magnetic, and shallow stratigraphic structure measurements, and the uploaded dataset consists of shallow sub-bottom profile data and side-scan sonar data.
