Researchers at the Scripps Institution of Oceanography at the University of California, San Diego, collected 27,345 barrel-like photographs. They surveyed over 36,000 acres of the seafloor between Santa Catalina Island and the Los Angeles peninsula, in an area where elevated levels of the toxic chemical had previously been discovered in sediments and the environment.

Before 1972, when the Marine Protection, Research, and Sanctuaries Act, also known as the Ocean Dumping Act, was passed, historical shipping records indicate that mining industries in southern California used the basin as a dumping area.
Here’s one disturbing thing about COVID: It’s an unseen enemy. Two, it’s incredibly contagious. Three, you’re already infected, yet it still doesn’t hurt. This virus from hell is so sinister you’ll never know you re a carrier, unless to get “swabbed”, or start showing symptoms, a few days after contracting it.
But with swab testing inaccessible/too pricey in most parts of the world, you try and live a “normal” life until you, and those around you, start getting feverish, sneezing like crazy and start infecting others too.
And, unfortunately, people die from COVID. The primary route of transmission? There’s a growing body of evidence it’s through aerosol ultra-tiny particles loaded with virus wafting about in the air, especially in indoor settings. It’s how the the breath-and-sneeze-of-death cycle goes on, a growing number of scientists argue.

While evolution is normally thought of as occurring over millions of years, researchers at the University of California, Irvine have discovered that bacteria can evolve in response to climate change in 18 months. In a study published in the
Proceedings of the National Academy of Sciences, biologists from UCI found that evolution is one way that soil microbes might deal with global warming.
Soil microbiomes - the collection of bacteria and other microbes in soil - are a critical engine of the global carbon cycle; microbes decompose the dead plant material to recycle nutrients back into the ecosystem and release carbon back into the atmosphere. Multiple environmental factors influence the composition and functioning of soil microbiomes, but these responses are usually studied from an ecological perspective, asking which microbial species increase or decrease in abundance as environmental conditions change. In the current study, the UCI team investigated if bacterial specie
25,000 Barrels Possibly Laced With DDT Are Found Off California Coast
One researcher said the number of discarded drums far exceeded his expectations. “It was hard to wrap my head around the density of targets,” he said.

In 2011, a curious marine scientist captured a series of photos of the ocean floor that left him disturbed. Using a sea drone, he documented dozens of corroding industrial barrels, scattered 12 miles off the coast of Los Angeles. Tests later showed that the sediment inside contained exceptionally high concentrations of DDT, a pesticide banned in the 1970s, and other chemical waste.
