南海北部海底热流测量及分析

广州海洋地质调查局用德国产的微型温度传感器和自行研制的重力取样器组装成海底热流探针，并用该设备在中国南海北部开展了海底热流测量，这是国内首次独立开展此项工作，也是我国海洋地质和地球物理调查技术方法的新尝试.通过实测数据分析以及与1985年中美合作获得的西沙海域地热流测量剖面数据对比，表明测量数据可靠并具有良好的一致性.此项工作的成功，将有助于地热流测量工作的深入开展，进而提高我国海底天然气水合物的勘探和海洋地质基础研究的水平.

The marine heat flow survey and the result discussion in the northern part of South China Sea

Guangzhou Marine Geological Survey constructed the marine geothermal survey instrument by setting the Germany made micro-temperature logger on the self made gravity coring tube. And the subsequent geothermal survey is made in the north of South China Sea. It is the first time for China to do such kind of thing independently and it marks the new method try in marine geology and geophysical survey of our country. Through analysis of geothermal data and comparing them with those obtained in Xisha trough by Sino-American cooperation, the good reliance and agreement of the data is illustrated. Its success will be helpful for the further work of marine geothermal survey and thus improve both the exploration of gas hydrates under the sea and the study of fundamental marine geology.
