General Bathymetric Chart of the Oceans (GEBCO)
Definition
The General Bathymetric Chart of the Oceans (GEBCO) is an international project that provides the most comprehensive, precise, and up-to-date global bathymetric maps and datasets. Bathymetry is the study and mapping of the seafloor's topography, akin to the topographic mapping of terrestrial environments. GEBCO's data and charts are crucial for understanding underwater terrain features, measuring ocean depths, and providing baseline information for oceanographic studies, marine navigation, and infrastructure development.
What is Charting out Elevation Paths along the Ocean with GEBCO?
Charting out elevation paths along the ocean using GEBCO involves creating detailed maps that depict the variations in seafloor depth and elevation across the globe. These maps are generated from a combination of ship-based sonar measurements, satellite altimetry, and other advanced surveying techniques. The primary purpose is to offer accurate and accessible bathymetric data for a range of applications, including marine science, environmental management, and commercial maritime operations. The bathymetric charts produced allow researchers and decision-makers to visualize undersea topography, understand geological processes, and support marine spatial planning efforts.
