Soundings in the Gulf of California and off the West Coast of Lower California in 1939

The soundings dealt with in this report were taken on Cruises VII and VIII of the "E. W. Scripps." In the Gulf of California the sounding lines mainly follow cross sections the locations of which were determined by the hydrographic program, but between these cross sections lines were run parallel to the coast line with minor detours for sounding purposes only. The Ballenas Channel was crossed and recrossed in an attempt to locate the maximum depth of the Ballenas Trench and the sill depth between the trench and the outer part of the Gulf.
