SAN DIEGO - San Diego photographers are taking advantage of the serene and luminous glow of the surf this week.Eerie neon blue waves have been seen against San Diego's shore this week, creating some rare photo opportunities. The phenomenon is created when a red tide, which is algae bloom filled with phytoplankton called "dinoflagellates," rolls off waves onto or near the shoreline.The organisms react with a bioluminescent chemical reaction when jostled as a way to warn predators, to lure prey, or communicate within their species. The blue glow can be created by a simple step in the water or crash of a wave.IN SAN DIEGO...The current red tide is being caused by massive numbers of dinoflagellates including "Ceratium falcatiforme" and "Lingulodinium polyedra," according to the Scripps Institution of Oceanography at UC San Diego.The Scripps Institution of Oceanography at UC San Diego is not affiliated with The E.W. Scripps Co., the parent company of this station. Researchers do not know how long this current red tide will last or "the full spatial range of the bloom." In the past, blooms have lasted anywhere from a week to a month or more.San Diego's last red tide event in September 2013 lasted one week, while the previous one in October 2011 lasted a month, according to researchers. Previous ones have lasted even longer.Monday's event was captured from La Jolla to Encinitas. Scripps recommends viewing the marine event from a dark beach at least two hours after sunset, though visibility is not guaranteed.IS IT HARMFUL?...In some areas, a red tide can be toxic to local marine life. In California, the majority are not caused by species that produce toxins, such as domoic acid, according to researchers. However, it's still best to be cautious around the bloom.The Southern California Coastal Ocean Observing System at Scripps samples the water for potential harmful algal toxins weekly.Red tides are unpredictable events and do not always give off bioluminescence, Scripps said.BUT WHY IS IT RED?...The red coloration is due to the high number of organisms in the water. During the day, organisms will swim to the surface to soak in sunlight. Each cell contains a little sunscreen that gives off the color, according to Scripps.When these organisms gather at the surface for sunlight, they can create an especially intense red.Researchers say a combination of physical, chemical, and biological factors are the driving forces behind allowing red tides to form. 2586

SAN FRANCISCO (AP) -- A coded letter mailed to a San Francisco newspaper by the Zodiac serial killer in 1969 has been deciphered by a team of amateur sleuths from the United States, Australia and Belgium.The San Francisco Chronicle reports Friday the cipher is one of many sent by a killer who referred to himself as Zodiac in letters sent to detectives and the media.According to code-breaking expert David Oranchak, the cipher's text includes: "I am not afraid of the gas chamber because it will send me to paradise."The Zodiac terrorized Northern California communities and killed five people in the Bay Area in 1968 and 1969. 637

SAN FRANCISCO (AP) — Gov. Gavin Newsom declared an emergency Tuesday over wildfires burning throughout California as the state's power grid operator pleaded for continued conservation to avoid rolling blackouts. The grid operator praised residents and businesses for astonishing conservation efforts that kept the power on Monday night. The state is in a days-long heatwave that has stressed the electrical system and resulted in rolling blackouts over two nights last weekend. Outages, excessive heat, wildfire and the pandemic have people on edge. Evacuations were in effect or growing in several Northern California communities because of growing fires. Newsom demanded an investigation into two smaller weekend blackouts. 733
