Water decreases with depth to a minimum value increasing again to a maximum in the Warm Deep. The boundary between them can be taken to lie midway between these two depths (Deacon, 1933).

At other stations on the o° Line the depth of the Antarctic Inter- mediate water was estimated in the same way and found to lie at 1620 m. at St. 2532; 900 m. at St. 2023; 1250 m. at St. 2024; 800 m. (?) at St. 1776; 1400 m. at St. 1775; 900 m. at St. 2387 and at approximately 1500 m. at St. 2386. (b) Warm Deep Water, with its principal component of movement directed south lies below the Antarctic Intermediate Water at considerable depths in the Tropical, Sub-Tropical and Sub-Antarctic
