The <Antarctic Convergence> is the circumpolar oceanic transition where cold Antarctic waters meet and mix with warmer waters farther north. It is associated with the <Antarctic Polar Front>, a boundary between contrasting water masses rather than a fixed line on a map. The Australian Antarctic Program identifies this mixing region and its enhanced nutrient concentrations.<Antarctic geography by Australian Antarctic Program>[Southern Ocean paragraphs: meeting and mixing of cold Antarctic and warmer northern waters, and nutrient enrichment]{ref}
A ship crossing the region can record a marked change in near-surface <temperature> together with changes in the vertical water-column structure. The physical distinction is between water masses with different <density> and thermal properties, so a temperature section is more informative than latitude alone. The <Antarctic Circumpolar Current> follows an eastward path around the continent; the <Antarctic Convergence> identifies a frontal region within this broader circulation.
