Thus the two deep basins of the Bransfield Strait may be connected by a flow of warm deep water. Further soundings on the line between Deception Island and Trinity Island are urgently needed. DECEMBER 1930 In late December 1930 a line of stations was attempted by the ' Discovery II' from midway between Elephant and Clarence Islands to Joinville Island. Unfortunately after St. 541 heavy pack-ice, which stretched as far as could be seen, prevented any further stations being made in this direction. A new line of stations was then made between Cape Melville and Trinity Peninsula and another between Snow Island and Fig. 39. Surface salinity: December 1930. Trinity Island. Temperature observations and samples of salinity and phosphate content were taken at all stations, with samples for oxygen content determination at alternate stations. Horizontal sections are given for temperature, salinity and density in Figs. 39-41. The three lines of stations are rather too far apart to show the surface movements in any detail. In general the surface salinity and density increase in all three sections towards Trinity Peninsula, and as usual the surface water at the north- east end of the strait is colder than that at the south-west. Compared with the observa- tions made by the 'William Scoresby' in November of the previous year, the surface in December is composed of warmer but more dense water. This is explained
