Notes on Oceanographic Station Curves 



Thermosteric anomaly (oblique lines) are in centiliters per ton (Montgomery 1954). Where 

 temperatures of paired thermometers differed by more than 0,05°C. below 300 m. or more than 

 O.IO'C. above 300 m. , both values are plotted and designated by the synabol-'-'J- . The other vari- 

 ables are plotted for each of the temperature values. When the station curve is not drawn through a 

 plotted value, it is considered a gross error and not used. 



Explanatory code for station curves: 



^ Reversing thermometer temperatures °C. 



• BT temperature °C. 



Salinity /oo. 



^ Dissolved oxygen ml. /L. 



Notes on Observed Oceanographic Data 



Where more than one cast was made on a station, they are separated by a horizontal line. 

 The cast number is indicated by a Roman numeral in the margin. 



Where the corrected readings of the paired protected thermometers differed by more than 

 O.OS'C. below 300 m. or more than 0.10°C. above 300 m. , both temperature values are tabulated 

 and the depth and salinity are repeated. Delta-t calculated using each temperature value is carried. 



Explanatory code for tabulated data: 



NG - The value or line is in error and is discarded, 

 Q - The value seems questionable but was used in 



construction of the station curve. 

 P - The value is questionable and while carried was 

 not used in drawing the station curve. 

 NS - No sample. 

 (2) . Indicates H S precipitate in salinity sample. 



NOTE: In calculating the depths of reversal from the readings of unprotected reversing thermometer s, 



an error was introduced into the formula D = Tu - Tw. Instead of the factor l/(Qxp„),

 values for (1/Q)xp were used. Therefore, multiplication of depth in table 13 by 0.942 



will give the proper value for the depth of each observation.
