Bottom water throughflows at the Rio de Janeiro Fracture Zone (22°S) and Rio Grande Fracture Zone (26°S) of the Mid‐Atlantic Ridge are identified from hydrographic anomalies observed along 9°W in the Angola Basin. The throughflow water is supplied by a meridional band of cold and fresh water lying against the western flank of the Ridge.
