Table 6. — Temperature and Density, Buzzards Bay, March, 1908. 



March. — Another set of determinations was made on March 20 and 21,1 908 (tables 

 5 and 6; chart 213). Owing to the inclemency of the weather and to the fact that only 

 the Bliic Wing was available for the work, a smaller number of soundings was made at 

 this time, and indeed the lower part of Buzzards Bay was entirely neglected. The 

 results are none the less interesting. The mean for the entire set of 36 determinations 

 (including both surface and bottom) was 36.71°. A high degree of uniformity was 

 manifest throughout the entire region, for the most extreme temperatures recorded 

 were 36.1° and 37.6°, while the average deviation (i. e., the average departure from 

 the average) ^vas only 0.32°. Moreover, such slight differences as did occur seemed 

 to bear no definite relation to locality.
