EXPLANATION OF DATA PAGES 



GENERAL 



Each of the items appearing on the data pages is explained below. 

 The vertical arrows shown in some of the column headings indicate the 

 location of decimal points. The presence of an asterisk to the left of 

 the data indicates that data as doubtful, hence it was not used in the 

 construction of the curve from which the interpolated values (standard 

 depth values) were derived. Observed values which were obviously false 

 were omitted entirely. 



SURFACE OBSERVATIONS 



1. Cruise Number . This number is arbitrarily assigned. It 

 identifies the cruise and provides a means of sorting from the IBM 

 files all cards pertaining to that particular cruise. Cruise number 

 00505 to the USS BURTON ISLAND (AGB-1). 



2. Station Nmnber . Stations are numbered consecutively, starting 

 with one, at the beginning of each cruise. Therefore, for a complete 

 identification of a particiilar station, both cruise and station number 

 are necessary. 



3. Date . Month and day aire given in Arabic numerals. The last 

 three figures of the year are indicated. The havoc is Greenwich Mean 

 Time and is that hovir nearest to the start of the first cast. 



k. Latitude and Longitude. The position of the sta.tion is given 

 in degrees and minutes, 



5. Sonic Depth . Sonic Depth is the uncorrected sounding for the 

 station, recorded in meters. 



6. Maximum Sample Depth . he maximum depth from which a water 

 sample was obtained at the station is given to the nearest 100 meters. 



7. Wind. Wind speed is given in meters per second. Direction 

 from which the wind blows is coded in degrees ture to the nearest ten 

 degrees. The last zero is omitted. North is 36 on this scale and calm 

 is 0. See Tables Defining Code Symbols - I, Compass Direction Conversion 

 Table for Wind, Sea, and Swell Directions. 



8. Anemometer Height. The height of the anemometer above the 

 waterline is given in meters. 



9« Barometric Pressure . Barometric pressure is coded in milli- 

 bars, neglecting the 900 or 1000. Thus, 996 millibars is coded as 96 

 and 1008 millibars is coded as 08.
