Scripps Institution of Oceanography has published a report indicating that a massive DDT (dichlorodiphenyltrichloroethane) dumping site was recently discovered at the bottom of the ocean floor off the coast of Los Angeles.
Underwater drones equipped with sonar technology mapped out 36,000 acres of seafloor between Los Angeles and Santa Catalina Island, which led them to the discovery that at least 27,000 barrels of DDT are nested there.
Scientists also found an excess of 100,000 debris objects related to the illegal dumping, which probably occurred at some point back during the time of World War II when DDT was still legally in use.
This particular area of ocean floor has previously been identified as a dumping site for the industrial complex of Southern California. However, it was not known until now that large quantities of DDT are hiding there well beneath the surface.

A system developed by Sonardyne to study ocean floor movement was recognized with a Queen’s Award for Enterprise in Innovation, the highest award a UK business can receive.
Developed over more than a decade, Sonardyne’s seabed deformation monitoring system is designed to provide engineers and scientists with new understanding of the seafloor and the physical processes that act upon it.

All photos and videos were shot following physical distancing guidelines, and with staff wearing face coverings. AMES, Iowa Iowa State University may not be the first university you think of when it comes to marine biology. That didn’t stop Toni Sleugh from turning her Iowa State experience into exactly what she wanted in terms of marine biology, environmental conservation and management. Sleugh will graduate this weekend with a bachelor’s degree in biology and environmental studies.
State commission deems Walter Munk house, Seiche, eligible for National Register of Historic Places

The La Jolla Shores home of late oceanographer Walter Munk is eligible for and will be nominated to the National Register of Historic Places, according to a State Historical Resources Commission vote April 30.
The home, called Seiche (after a standing wave oscillating in a body of water), was built by Munk, known as the “Einstein of the Oceans” for his research at UC San Diego’s Scripps Institution of Oceanography, and his second wife, Judith, who died in 2006.
Technology Helps Determine Extent of Seafloor Dumpsite
NEWPORT BEACH, Calif. An area encompassing more than 36,000 acres containing more than 27,000 “barrel-like” images lying on the seafloor, stretching between Catalina Island and the coast off Los Angeles, has been documented by marine scientists.
The discovery was made during an expedition led by University of California–San Diego’s Scripps Institution of Oceanography.
Although widely reported in the media that the barrels contain the harmful chemical compound DDT, that information has not been confirmed.
Eric Terrill, director of the Marine Physical Laboratory at Scripps Institution of Oceanography and chief scientist for the Scripps Institute of Oceanography, told the Epoch Times that the expedition survey did not measure the exact contents inside the discovered barrel field.
