Hayford, his predecessor at the Coast and Geodetic Survey, he computed tables of the depth of isostatic compensation (the surface above which the weight of the crust per unit area is equalized). Bowie felt that this zone would occur at a uniform depth as predicted by John Henry Pratt, rather than at the varying depth predicted by Sir George Airy. He wrote Isostasy (1927). Pic. | |||
