On the basis of BT observations made at intervals of about one mile, a detailed temperature cross section of the cold-water belt along the northern edge of the Kuroshio is presented. Cold waters and sharp temperature inversions have been observed on the southern and northern margins of the cold-water belt. Within the cold-water belt, except in a narrow noninversion area, many temperature inversion layers have been observed, and the colder and warmer waters are arranged in a complicated pattern....
