. Fig. 3. Temperature-salinity diagrams for Sts. WS 400, WS 384 and WS 385. Before discussing the hydrology of the Bransfield Strait and the manner in which it is influenced by the topography of the sea-bottom, the following comparison of con- ditions inside and outside the strait will be of service. For this purpose three stations from February 1929 have been selected: St. WS 400 situated in 620 07' S, 620 33' W, in the Drake Passage just north of the Bransfield Strait, and Sts. WS 384 and WS 385, situated both at the north-east end of the strait in 620 25' 40" S, 580 06' 10" W

The temperature and salinity data from these stations have been plotted in Fig. 3 as temperature-salinity diagrams. The figures on the curves represent the depths in metres of the observations. In the Antarctic Zone of the South Atlantic Ocean the water masses may be divided into three layers. The uppermost consists of Antarctic surface water, the middle layer
