2024年7月25日,我国“海洋地质二十六号”调查船在琼州海峡顺利完成列装后的首次“船装”结合海试工作。此次海试旨在验证该船的多项关键技术,包括多波束测探、海洋磁力测量和单道地震测量等,为未来的海洋地质调查作业提供强有力的技术支持。

多波束测探技术能够通过广角度发射和多信道定向接收,获取水下高密度条幅式海底地形数据,大幅提升海底地形勘测的精度和效率。海洋磁力测量利用海底岩层的磁性差异,对于研究海洋地质构造、矿产资源预测以及海底扩张和板块构造具有重要作用。单道地震测量则能够穿透并分辨100-200米深的泥沙地层,广泛应用于海洋工程地质勘查和地质灾害预测。

“海洋地质二十六号”调查船的成功海试,不仅标志着我国在海洋地质调查领域的进一步发展,也为海洋工程开发、资源勘探和地质灾害预测等提供了重要支持。同时,这也将为我国和全球的海洋科学研究提供宝贵的数据支持。

中国地质调查局海口海洋地质调查中心技术方法室主任袁坤表示,海洋地质调查对于海洋工程建设至关重要,包括风电、港口、海上机场等项目选址与建设。此外,海洋地质调查还为科研和国防建设提供支持。

随着“海洋地质二十六号”调查船海试工作的顺利完成,我国在海洋地质调查领域的实力得到了进一步提升,为我国海洋科学研究的深入发展奠定了坚实的基础。

News Title: “Ocean Geology No. 26 Completes First Sea Trial”

Keywords: Sea Trial, Geology, Survey Vessel

News Content: On July 25, 2024, China’s “Ocean Geology No. 26” survey vessel successfully completed its first combined sea trial following its commissioning in the Qiongzhou Strait. This sea trial aimed to verify the vessel’s multiple critical technologies, including multi-beam echo sounding, marine magnetic survey, and single-channel seismic survey, providing strong technical support for future marine geological survey operations.

Multi-beam echo sounding technology can obtain high-density strip-shaped seafloor topographic data by broadcasting at a wide angle and receiving through multiple channels, significantly enhancing the accuracy and efficiency of seafloor topographic surveying. Marine magnetic surveying utilizes the magnetic differences of seafloor sediments, which is crucial for studying marine geological structures, predicting mineral resources, and understanding seafloor spreading and plate tectonics. Single-channel seismic surveying can penetrate and distinguish mud and sand layers up to 100-200 meters deep, widely applied in marine engineering geological exploration and geological disaster prediction.

The successful completion of the sea trial of the “Ocean Geology No. 26” survey vessel marks a further development in China’s marine geological survey field and provides important support for marine engineering development, resource exploration, and geological disaster prediction. It also offers valuable data support for marine scientific research both domestically and globally.

Yuan Kun, the Technical Methods Room Director of the Haiyang Marine Geological Survey Center of the China Geological Survey, stated that marine geological survey is crucial for the site selection and construction of marine engineering projects such as wind farms, ports, and offshore airports. Moreover, marine geological survey also supports scientific research and national defense construction.

With the successful completion of the “Ocean Geology No. 26” survey vessel’s sea trial work, China’s strength in the field of marine geological survey has been further enhanced, laying a solid foundation for the in-depth development of China’s marine scientific research.
