摘要:

中国科学院海洋研究所在开展西太平洋马里亚纳海山区多学科综合科学考察的过程中，利用“科学”轮船载的全水深多波束测深系统Seabeam3012对多个海山进行了地形测量工作。针对作业过程中遇到的恶劣海况导致采集数据质量差、多波束系统易检测错误海底信息、测线布设难度大等问题，提出了基于船体姿态对数据质量影响分析的多波束测线方向优化、基于地形变化并参考浅地层剖面资料的作业参数优化和基于实时采集情况的多波束采集测线布设优化等一系列措施，有效地提高了海山区多波束数据采集质量，并提高了作业效率。获得的高品质地形数据，为多学科协同研究奠定了基础，为ROV等设备的现场作业提供了安全保障。

Abstract:

In the courses of multidisciplinary comprehensive scientific investigation in the Mariana seamount area of the Western Pacific Ocean, Institute of Oceanography, Chinese Academy of Sciences has conducted several topographic surveys of seamounts using the full ocean depth multibeam bathymetric system Seabeam3012 on board the “KEXUE” ship. In view of the problems encountered during the process of operation, such as low data quality caused by poor sea conditions, detection of incorrect seabed information by the multibeam system, and difficulty in laying out survey lines, this study proposes a series of measures, such as multibeam survey line direction optimization based on the analysis of the influence of ship attitude on data quality, operation parameter optimization based on terrain changes and referring to shallow formation profile data, and layout optimization of multibeam acquisition line based on real-time acquisition. These measures have effectively improved the quality of multibeam data acquisition in seamount areas and enhanced the efficiency of operation. The obtained high-quality terrain data lay the foundation for multidisciplinary collaborative research and provide a safety guarantee for the field operation of remotely operated vehicle (ROV) and other equipment.
