The Scripps Institute of Oceanography was 

 established at the end of the last century 

 by Dr. William E. Ritter in San Pedro, 

 California. In 1905 it was moved to La Jolla 

 where it was made part of the 

 University of California. 



The western (especially the northwestern) 

 Pacific Ocean contains the most extensive 

 continuous area of sea floor deeper than 

 16,400 feet, and wide areas of a depth 

 greater than 19,700 feet. Deep-sea trenches 

 are a feature of the western marginal 

 region, and the greatest depth in the ocean, 

 35,800 feet, is in the Marianas Trench.
