On July 25, the "Marine Geology No. 26" survey ship completed its first "ship installation" combined with sea trials after being put into service in the Qiongzhou Strait.

The sea trial mission includes multiple key tests such as multi-beam, ocean magnetism, single-channel seismic, and ship power system.The aim is to obtain important test data and provide strong technical support for the next stage of ocean and island reef survey operations.

Multi-beam sounding refers to the acquisition of underwater high-density strip-like seabed topography data through wide-angle transmission and multi-channel directional reception technology, which can greatly improve the accuracy, resolution and work efficiency of seabed topography surveys.

Marine magnetometry is a method that uses the magnetic differences of seabed rock layers to detect the Earth's magnetic field. It plays a key role in studying marine geological structures, predicting mineral resources, and studying seafloor spreading and plate tectonics.

Single-channel seismic measurement is a technology that detects the structure of the seabed strata through the propagation and reflection of seismic waves. It can penetrate and distinguish mud and sand strata 100-200 meters deep. It is widely used in marine engineering geological surveys and geological disaster prediction, providing important data support for the formation process of strata and the identification of seabed geological bodies.

The application of these technologies will greatly improve the efficiency and accuracy of scientific research and bring new breakthroughs to my country's marine scientific research.

According to Yuan Kun, director of the Technical Methods Office of the Haikou Marine Geological Survey Center of the China Geological Survey, marine geological surveys will provide key data for marine engineering construction, including topography, stratigraphic structure, etc., to support the site selection and construction of projects such as wind power, ports, and offshore airports. At the same time, it is of great significance to scientific research and national defense construction.

along with"Marine Geology No. 26" survey shipSea trialsSuccessful completion of work,not onlyIt marks the further development of my country's marine geological survey field.It provides important support for marine engineering development, resource exploration and geological disaster prediction, and alsoIt will provide valuable data support for marine scientific research in my country and around the world.
