 (Plates I— X) 



INTRODUCTION 



THE following lists contain particulars of all stations made by the R.R.S. 'William 

 Scoresby' between January 1928 and the 6th of May 1929, of stations made by a 

 member of the Discovery Investigations staff from the whaling factory S.S. 'Anglo- 

 Norse' near the South Sandwich Islands from November 1927 to February 1928, and 

 of stations made by another member of the staff from the whaling factory S.S. 'C. A. 

 Larsen' in the Ross Sea from November 1928 to February 1929. 



Stations made by the 'William Scoresby' are entered first and have the letters WS 

 prefixed to their numbers. Those made near the South Sandwich Islands follow (pp. 

 1 14-123) and are distinguished as SS i, SS 2, etc. Finally (pp. 124-13 1) those made 

 in the Ross Sea are given, numbered RS i, RS 2, etc. 



Details of the nature of the data in the lists are to be found in the Introduction 

 (pp. 3-5) of the previous Station List (vol. i, pp. 1-140) except those noted below. 



The abbreviations used in denoting the nature of the bottom, now being used by 



the Admiralty, are as follows : 



G. gravel 

 gn. green 



gy- grey 



h. hard 



I. large 



It. light 



M. mud 



Md. madrepore 



Oz. ooze 



P. pebbles 



— placed above the figure for the sounding indicates that bottom was not reached. 



Estimation of hydrogen-ion concentration was made by the colorimetric method, 

 cresol red being used as indicator with McClendon's standards. Phosphate content was 

 again determined by Atkins' method. It was not possible to make determinations of 

 phosphate content and hydrogen-ion concentration at the time the samples were taken. 

 The date on which the estimations were made is entered in the " Remarks " column after 

 the letter A (analysed), thus A 18. ix. 28, etc.
