transfer at this section and small numbers of bergs reaching the 

 Grand Banks, and the significance of departures from normal baro- 

 metric pressure gradients in the vicinity of Davis Strait pointed out. 

 In the following table are given the data collected during the 1940 

 season and post-season cruises of the General Greene and thos'e collected 

 by the Northland in 1940 in Baffin Bay. Individual station headings 

 give the station number, date, geographic position, depth of water, 

 and dynamic height of the sea surface used in the construction of 

 the dynamic topographic charts shown in figures 18, 23, 24, 25, 

 26, 27, and 33. For stations 3074 to 3308, inclusive, the sea 

 surface is referred to the 1,000-decibar surface and the depth of 

 water is the uncorrected fathometer sounding based on a sound- 

 ing velocity of 1,433.8 meters per second for stations 3074 to 

 3187, and 1,430.5 meters per second for stations 3188 to 3308. For 

 stations 3309 to 3329, mclusive, the sea surface is referred to the 2,000, 

 decibar surface and for stations 3330 to 3342, inclusive, the sea surface 

 is referred to the 1,500-decibar surface and the depth of water for 

 stations 3309 to 3342 is the sonic sounding corrected for sounding 

 velocity and draft, but not for slope. Where the depths of the scaled 

 values are enclosed in parentheses the data are based on extrapolated 

 vertical distribution curves of temperature or salinity or both. 

 Asterisks appearing before observed temperatures indicate that these 

 temperatures were determined from the depth of reversal and the 

 corrected reading of an unprotected thermometer. The symbol at 

 signifies 1,000 (density — 1) at atmospheric pressure and temperature t.
