HYDROLOGY OF THE BRANSFIELD STRAIT 



i7 



The vertical sections of salinity, temperature and density (c7 ( ) for the line between 

 Livingston Island and Trinity Peninsula are shown in Figs. n-13. The surface 

 salinity is least and the temperature highest at the station nearest Livingston Island. 

 This station, 202, is in the north-east set and is the only station to show a positive 

 temperature range below the surface water ; at 300 m. it has an intermediate temperature 

 maximum of 0-36° C. At the other stations barely a trace of a temperature inversion 

 occurs below the surface and the influence of the warm deep water may almost be said 

 to stop at St. 202. The water below 300 m. at all stations consists of a mixture of 

 Antarctic surface water or warm deep water, as at St. 202, with increasing amounts 

 with depth of Antarctic bottom water.

 FEBRUARY 1929 



The hydro logical work in the Bransfield Strait which had been done in April 1927 

 by the R.R.S. 'Discovery' was repeated and augmented by the R.R.S. 'William 

 Scoresby' in February 1929, when, in addition to repeating the lines of stations from 

 King George Island and Livingston Island to Trinity Peninsula, a new line of four 

 stations was made at the southern end of the strait from Brabant Island to Smith Island, 

 with one station between the islands of Smith and Snow, and another between Living- 

 ston and Deception Islands. Figs. 14-16 show the distribution of the surface salinity, 

 temperature and density (<r<).
