World Ocean World Ocean The World Ocean or Global Ocean (colloquially the sea or the ocean) is the interconnected system of Earth's oceanic waters, and comprises the bulk of the hydrosphere, covering (70.8%) of Earth's surface, with a total volume of roughly . The unity and continuity of the World Ocean, with relatively free interchange among its parts, is of fundamental importance to oceanography.

World Ocean Database Project Float (PFL), Moored Buoy (MRB), Drifting Buoy (DRB), Gliders (GLD), Autonomous Pinniped Bathythermograph (APB). The data in the World Ocean Database are made available through the online search and retrieval system known as WOD"select". The World Ocean Atlas (WOA"select") series is a set of gridded (1° grid), climatological, objectively analyzed fields of the variables in the World Ocean Database. The WOA"select" is a selection tool by which the user can designate a geographic area, depth, and oceanographic variable to view climatological means or related statistics for a given variable at the requested depth for the requested geographic area.
