Two new greenhouse gases are accumulating in the atmosphere, according to an international research team led by scientists from the Scripps Institution of Oceanography in the US and CSIRO scientist, Dr Paul Fraser, from the Centre for Australian Weather and Climate Research. Nitrogen trifluoride (NF3) and sulfuryl fluoride (SO2F2) are powerful greenhouse gases that have recently been discovered to be growing quickly in the global background atmosphere. These gases are used in industrial...

California Sea Grant researchers say they've determined Northern California septic tanks are leaking nitrogen and phosphate into Pacific coastal waters. The researchers said they have discovered elevated levels of the nutrients in the surf zone during periods of high groundwater flows to the beach. The scientists said such leakage can cause algal blooms. Our project is one of the first in California to show definitively that septic tanks can affect coastal water quality through submarine...

U.S. scientists have discovered a fumigant pumped into tented houses to kill pests remains in the atmosphere six to 10 times longer than previously thought. Scripps Institution of Oceanography researchers at the University of California-San Diego said the greenhouse gas most often used to rid buildings of termites, rodents and other pests -- sulfuryl fluoride -- remains in the atmosphere about 36 years. A Scripps team led by Jens Muhle found the concentration of the gas rose at a rate of 4...

Sulfuryl fluoride, a compound developed to phase out the use of methyl bromide in fumigants has been implicated as a possibly significant contributing factor for greenhouse warming, according to an international team of researchers. Methyl bromide has been used to control insect infestations in grain storage facilities. As methyl bromide use was being reduced under the Montreal Protocol because of its detrimental effects on the environment, scientists introduced sulfuryl fluoride as its...

Snapshots trace shrinking 'trophy fish' over a generation of sport fishing A unique study by a scientist at Scripps Institution of Oceanography at UC San Diego has provided fresh evidence of fishing's impact on marine ecosystems. Scripps Oceanography graduate student researcher Loren McClenachan accessed archival photographs spanning more than five decades to analyze and calculate a drastic decline of so-called "trophy fish" caught around coral reefs surrounding Key West, Florida. In a paper...

The U.S. Department of Commerce has awarded the Scripps Institution of Oceanography $12 million to construct a state-of-the-art ocean science research lab. The award, from the department's National Institute of Standards and Technology, will allow Scripps to construct the Marine Ecosystem Sensing, Observation and Modeling Laboratory on its University of California-San Diego campus. Officials said the new lab will conduct research on marine ecosystem forecasting and become a resource for other...

Professor Ralph Lewin, known as the father of green algae genetics, died in his sleep Sunday at his California home from esophageal cancer. Lewin, 87, a scientist, poetry author and professor, spent nearly 48 years at the Scripps Institution of Oceanography at the University of California-San Diego and was considered a leading authority in multiple areas of marine biology, Scripps said in a statement Thursday. Lewin joined the Scripps institution as an associate professor of marine biology in...

Fishing activities are stunting population growth of a type of Pacific Ocean dolphin despite dolphin-safe practices, U.S. university researchers said. The study by Scripps Institution of Oceanography at the University of California-San Diego revealed negative impacts from fishing activities remain, despite adoption of regulations and agreements designed to reduce dolphin deaths from by-catch in which animals are caught unintentionally along with the intended targets. The research by the...

Southern California Edison (SCE) today announced completion of the largest environmental project of its kind in the United States - a 175-acre artificial giant kelp reef off the coast here. With the placement of 120,000 tons of rock on the ocean floor, the project is expected to produce the nation's first sustainable artificial kelp forest attracting many species of coastal fish and invertebrates dependent on such underwater habitats for shelter and food. "This reef project is a blueprint...
