. Fig. 8. Vertical section of salinity: King George Island to Trinity Peninsula, April 1927. topography show that the level of the surface of the sea at St. 198 is higher than at Sts. 197 and 199 on either side. The movement of water has a more or less constant velocity down to 200 m. at St. 198 and then decreases with depth. In a later part of this report considerable doubt is thrown on many of the temperature and salinity results of the line of stations from King George Island. In such an enclosed basin as the Brans- field Strait it is surprising to find so much horizontal circulation below

In such an enclosed basin as the Brans- field Strait it is surprising to find so much horizontal circulation below 200 m. as 1 In considering these sections, some observations of salinity have been neglected, and in particular St. 197, 800 m., 35-06°/00, St. 198, 1500 m., 34-87 °/00, and St. 199, 700 m., 35'0I700- ^ is considered that these salinities, abnormally high for the latitude, are due to the partial freezing of the sea water in the reversing water bottles before a sample could be taken, with the consequence that the salinity of the remaining water became considerably increased. During these particular stations air temperatures of - 7° to — io° C. were recorded. All three salinities were the result of duplicate titrations.
