In hydrology, an oceanic basin may be anywhere on Earth that is covered by seawater, but geologically, ocean basins are large geologic basins that are below sea level. An ocean is a huge body of salt water . Hydrologically some geologic basins are both above and below sea level, such as the Maracaibo Basin in Venezuela, although geologically it is not considered an oceanic basin because it is on the continental shelf and underlain by continental crust.
