bathymetric charts

Bathymetric charts are maps that show the underwater features of oceans, seas, and lakes, similar to how topographic maps depict land elevations. They use contour lines and colors to represent varying depths and underwater landscapes, such as mountains, valleys, and plains beneath the surface. These charts are essential for navigation, marine research, fishing, and environmental studies, helping us understand the shape and structure of underwater terrains and their influence on water flow, habitats, and human activities.
