Vermilion Sea Expedition, 1959

Vermilion Sea Expedition ships R/V SPENCER F. BAIRD and R/V HORIZON explored and delineated the bathymetry, tectonic elements and crustal structures of the entire length of the Gulf of California. The tectonic relations that were revealed anticipated the plate tectonics theory of the 1960’s. Sediment distribution, thickness and individual characteristics within the several basins were determined.
