Scripps Institution of Oceanography

The motor vessel HORIZON of the Scripps Institution of Oceanography, (a converted Navy fleet tug, formerly ATA-180, which after the war was at Bikini during operation CROSSROADS) and the EPCE(R)-857, a 220-foot research vessel assigned to the U. S. Navy Electronics Laboratory, returned (HORIZON October 28, EPCE(R)-857 on November 3) from an expedition lasting somewhat over three months, to explore the ocean waters and the seabottom of the eastern central Pacific, between San Diego, the equator, and the Marshall Islands, and extending north as far as 40° north latitude. The two ships travelled a total distance of over 29,000 miles, considerably more than the distance around the world at the equator.
