2015-2016南海冷泉数据集（重力仪）

2015-2016年，中国科学院海洋研究展开对南海冷泉综合调查航次。本部分数据为“科学”船载重力仪在航次进行过程中所记录的重力数据。重力仪采用Marine Gravity Meter KSS 32-M系统，它是测定重力加速度的仪器，主要用来在地面上测量重力加速度值相对变化的一种高精度的仪器。KSS 32-M海洋重力仪可用于海洋连续重力调查，包括油气调查和科学研究调查。整套仪器包括重力仪主体(弹性系统，恒温装置、阻尼装置、指示系统等)；模拟的或数字的记录器；控制器；常平架或陀螺稳定平台；电源几大部分。

From 2015 to 2016, the Institute of Oceanology, Chinese Academy of Sciences carried out a comprehensive survey cruise for cold seeps in the South China Sea. The data presented herein are the gravity data recorded by the shipborne gravimeter aboard the RV "Kexue" during the survey cruise. The gravimeter employed is the Marine Gravity Meter KSS 32-M system, a high-precision instrument developed to measure relative changes in gravitational acceleration. The KSS 32-M marine gravimeter can be used for continuous marine gravity surveys, including oil and gas exploration and scientific research surveys. The complete instrument system consists of several core components: the main gravimeter body (including the elastic system, constant temperature device, damping device, indicating system, etc.), analog or digital recorders, controllers, gimbals or gyro-stabilized platforms, and power supply units.
