BIGELOW: COAST WATER EXPLORATION OF 1913.

but as noted (p. 221) the water was even denser on George's Bank and 

 in the Gulf of Maine. In general, the density rose from southwest to 

 northeast, corresponding to the general decline of surface temperature 

 (Fig. 1). 



At all our stations south of Cape Cod the water was heaviest at 

 the bottom, i. e., it was in stable equilibrium, as is the rule everywhere,

in temperate regions in summer. But it varied so much, level for 

 level, at different stations, as to suggest a potent cause for circulation. 

 To facilitate comparison with salinity and temperature, density is 

 reproduced here by corresponding profiles.
