abstract:Circumpolar Deep Water (CDW) is a designation given to the water mass in the Pacific and Indian oceans that essentially characterizes a mixing of other water masses in the region. A distinguishing characteristic is the water is not formed at the surface, but rather by a blending of other water masses, including the North Atlantic Deep Water (NADW), the Antarctic Bottom Water (AABW), and the Pacific Intermediate Water Masses.
And water masses within and north ofPrydzBay are identified as summercoastalsurfacewater, the Prydz Bay winter water, the Prydz Bay shelf water, and the CircumpolarDeepWater.
