Arctic Ocean basins (these being the Pacific, Atlantic, and Indian Oceans) and where the circulation is dominated by thermohaline forcing”. The Arctic Ocean has a total volume of 18.07×10 km, equal to about 1.3% of the World Ocean. Mean surface circulation is predominately cyclonic on the Eurasian side and anticyclonic in the Canadian Basin. Water enters from both the Pacific and Atlantic Oceans and can be divided into three unique water masses. The deepest water mass is called Arctic Bottom Water and begins around depth. It is composed of the densest water in the World Ocean and has two main sources: Arctic
World Ocean Atlas World Ocean Atlas The World Ocean Atlas (WOA) is a data product of the Ocean Climate Laboratory of the National Oceanographic Data Center (U.S.). The WOA consists of a climatology of fields of "in situ" ocean properties for the World Ocean. It was first produced in 1994 (based on the earlier "Climatological Atlas of the World Ocean"), with later editions at roughly four year intervals in 1998, 2001, 2005, 2009, and 2013. The fields that make up the WOA dataset consist of objectively-analysed global grids at 1° spatial resolution. The fields are three-dimensional, and data are typically interpolated onto 33
