Note
The PLAN operates a variety of Haiyang [ = Ocean] Type 636/636A distant-ocean survey ships, analogs of the U.S. Navy’s Pathfinder class hydrographic survey ships. These ships carry out bathymetric surveys and acquire oceanographic and meteorological data, which function inputs for the manufacturing of charts and the improvement and development of forecasting systems.
The marine survey refers back to the research of hydrological, meteorological, physical, chemical, biological, and sedimentary distribution and adjustments in a selected sea area. In the military field, marine surveys also are extraordinarily important, such as the study of ocean acoustics, the exploration of numerous topographical functions at the seabed, and the usage of deep-dive techniques.
