Chemical Dumpsite Offshore Southern California
In March 2021, an expedition led by Scripps Institution of Oceanography mapped more than 36,000 acres of seafloor in the San Pedro Basin in a region previously found to contain high levels of the toxic chemical DDT in sediments and the ecosystem. The survey on Research Vessel Sally Ride identified an excess of 27,000 targets with high confidence to be classified as a barrel, and an excess of 100,000 total debris objects on the seafloor.
CHEMICAL AND BIOLOGICAL SAMPLING OF BARRELS AND SEDIMENT
In August 2021, scientists from Scripps Oceanography led an expedition off the coast of Southern California to survey the biodiversity of deep sea areas rich in minerals that are of interest to deep sea mining developers around the world. With an underwater robot, the team also explored the DDT dumpsite, collecting sediment and biological samples around six barrels to understand potential ecological effects of the dump site and to determine the levels of DDT present in the ecosystem.
EXPERTS AT SCRIPPS
UC San Diego’s Scripps Institution of Oceanography has a variety of scientific experts on this issue. These scientists can provide expertise on methods to identify the scope and condition of the dumpsite, the processes that transport and alter composition of the dumped chemicals, biological pathways that may lead to human exposure these impacts, and more.
