HYDROLOGY OF THE BRANSFIELD STRAIT 23 water in the north-easterly current near the South Shetland Islands, and that in the remainder of the Bransfield Strait, influenced by the Weddell Sea and by the production in winter of Antarctic bottom water, is nowhere more clearly demonstrated than by a comparison of the temperature at 300 m. at Sts. WS 393 and WS 392. St. WS 393, situated in the north-easterly flowing current, has a temperature of 0-70° C. at 300 m., whereas St. WS 392 has a corresponding temperature ofâ 1-05° C. Thus a temperature difference of 1750 C. is shown at 300 m. between two stations both inside the strait and approximately 12 miles apart. The temperature of 0700 C. at 300 m. at St. WS 393 is due to the presence of warm deep water, and that of - 1-05° C. at 300 m. at St. WS 392 is due to mixed water containing a high proportion of Antarctic bottom water.

WS 392 and WS 393. diagrams showing the relation between temperature and salinity for these two stations are shown in Fig. 23. The figures alongside the curves represent the depths in metres of the observations. The portion BC of the diagram for St. WS 393 represents the mass of mixed water occurring between the cold nucleus of the Antarctic surface water at 40 m. and the intermediate maximum temperature of the warm deep water at 300 m. The diagram for St. WS 392 shows that the mass of mixed Antarctic surface water and warm deep water is missing at this station. At St. WS 390 an accumulation of slightly less saline but relatively warmer water in the 0-100 m. layer corresponds to an inflow of surface water from the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of t
