1. Weather was recorded according to the ww (present weather) code in the U. S. Weather 

 Bureau, Circular M, 8th edition. Manual of Marine Meteorological Observations. 



2. The wind velocity was measured with an anemometer 30 M above the sea surface. The 

 speed is recorded in knots; the direction in degrees true. 



3. Any departure from the POFI standard 13-bottle cast is explained in a footnote. 



4. If a value is definitely determined to be in error, it is deleted from the tabulations and 

 an explanatory footnote appended. If a value appears to be anomalous, but there is un- 

 certainty, the value is carried with a footnote. 



5. Horizontal line{s) separating particular depths denotes more than one cast. The time 

 and wire angle for each cast is carried in the station headings.
