Book Description

Excerpt from Smithsonian Miscellaneous Collections, Vol. 91 The sonic sounding operations were conducted by T. Townsend Brown, of the Naval Research Laboratory, Washington, D. C., assisted by E. R. Fenimore Johnson, Anthony Wilding, and the Misses Ena and Florence Douglass. The soundings as here cited are unreduced, using as the basis for notation a 400 fathoms per second interval. These soundings will, therefore, when eventually corrected, record a considerably greater depth than here indicated. We are deeply indebted to the Hydrographic Office of the United States Navy for the preparation of the accompanying chart.
