A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [26] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
Some symbols describe the sea bed with information such as its depth, materials as well as possible navigational hazards such as shipwrecks. Other symbols show the position and characteristics of navigational aids such as buoys , lights , lighthouses , coastal and land features and structures that are useful for position fixing .
