A distinction is drawn between classically defined Antarctic Bottom Water and Weddell Sea Bottom Water, defined as water with potential temperatures less than -0.7°C and characterized by larger near-bottom temperature gradients and by a slope change on the θ−S correlation curve. The outflow of this water is strongly influenced by the topography of the Scotia Ridge. The flow of water out of the Weddell Sea was calculated from current measurements and the relative geostrophic speed. The total adjusted geostrophic transport is approximately 97 × 106 m3 s−1. Approximately 69 × 106 m3 s−1 is classically defined Antarctic Bottom Water of which about 16 × 106 m3 s−1 is Weddell Sea Bottom Water with potential temperatures less than -0.7°C. From 12 to 31% of the Weddell Sea Bottom Water is newly-formed bottom water and from 2 to 5 × 106 m3 s−1 represents the production rate of bottom water.
