Nautical Term: Hydrographic vessel
Definition of Hydrographic vessel
A hydrographic vessel is a specialized marine craft specifically designed for the purpose of conducting surveys of the seabed topography, currents, and other hydrographic data, which are essential for safe and efficient marine navigation.
For instance, during a hydrographic survey by a research vessel, data on water depth, seabed composition, temperature, and salinity are collected using various hydrographic tools and instruments such as sonar, sub-bottom profiler, CTD (Conductivity, Temperature, Depth) rosette, and others. This data is then processed and analyzed to produce hydrographic charts and maps, which are essential tools for marine navigation and various marine research applications.
