SAN DIEGO (CNS) - Two researchers, including one from the Scripps Institution of Oceanography at UC San Diego, are in Antarctica in an effort to uncover the planet's oldest ice.The research trip is part of a cordial international race to find the ice, which will give geologists and climate scientists new insight into Earth's climate history. Scripps paleoclimatologist Jeff Severinghaus and University of Minnesota-Deluth geologist John Goodge arrived this month at an ice-drilling outpost at McMurdo Station, Antarctica.In October, Severinghaus and researchers at Princeton University published a study in the journal Nature analyzing a two-million-year-old ice core. However, that core was incomplete in its historical portrait of ancient air. According to Severinghaus' ice dating lab, the planet's oldest ice is roughly 2.7 million years old.RELATED: San Diego Zoo welcomes second rhino born via artificial inseminationSeaWorld frees whale tangled in 900 feet of rope off La JollaSan Diegans can fly over rush-hour traffic with FLOAT air service"That core ... was all broken up," Severinghaus said of the Princeton study. "It's like in archaeology when you find pieces of broken pottery you're trying to put back together."The two researchers are attempting to expedite the conventional ice drilling process, which currently takes roughly five years to dig two miles to the Antarctic ice shelf's deepest point. They believe their 50-ton drill could secure a 50-meter ice core with a full timeline of the continent's geologic development. Eventually, it could be used to dig to the continent's bedrock, which dates back 3 billion years.In addition to each other, geologists and climate scientists in the southern hemisphere are in a race against nature, as climate change continues to melt Antarctic ice and cause sea levels to rise, particularly on the continent's western edge, according to Goodge."The bigger question is what's happening in East Antarctica because there's a lot more sea level rise potential if it begins to melt as well," he said. "So we really need to understand what those conditions are."Once collected, the researchers will pack the ice samples in boxes until January, when the Antarctic sea ice thaws and the samples can be shipped to Port Hueneme in Ventura County. They will then be transported to the National Science Foundation's Ice Core Facility in Lakewood, Colorado, for study in late spring. 2439

SAN DIEGO (KGTV) — A beach on Naval Base Point Loma went from unsafe and unappealing to a sandy destination that also houses a new oceanic ecosystem.In the 1980s, Smuggler’s Cove was hit with erosion and until recently, was rocky and uneven.“This beach had virtually eroded away,” said Captain Ken Franklin, Commanding Officer of Naval Base Point Loma.In the past three years, a revitalization project has been in the works, with different additions to the beach coming from unique places. The Navy’s environmental team had the idea to use rubble and cement from a fuel pier that had been demolished to build an underwater reef. They planted eelgrass along the reef, restoring the habitat.“That actually enhances the fish production, enhances the overall ecology of the system. So it actually enhances and helps some of the protected species, with the birds, gives them food to eat, and overall enhance the production of the area,” said Navy marine biologist Sean Suk.Since the work started, the eelgrass has seen an estimated 700-1,000% increase, and 15-18 fish species have been spotted swimming around the new ecosystem.In addition, the Navy brought in sand that the Coast Guard had leftover from their dredging they had finished. This created a sandy beach, compared to the rocky area that was there before.“It’s a win for everybody. It’s a win the fleet, it’s a win for the warfighter, the family and for the environment, so all and all nirvana from my perspective,” said Franklin.A spokesperson for the Navy said biologist Mitchell A Perdue was one of the major driving forces behind the project, but he passed away suddenly last year, so the completion of the upgrade is in honor of him. 1702

SAN DIEGO (KGTV and CNS) -- Opening statements will likely begin Thursday morning in the retrial of Kellen Winslow II, who is charged with raping a woman in Encinitas and an unconscious teen in Scripps Ranch in 2003. Winslow was previously convicted of raping a homeless woman and exposing himself to two others. After a week of deliberations, the Vista jury found Winslow guilty of raping a woman in Encinitas and exposing himself to two others, but deadlocked on eight other charges. Those charges included rape and kidnapping in connection with two other women. RELATED: Kellen Winslow II to face second trial in North San Diego County sex assault caseSuperior Court Judge Blaine Bowman declared a mistrial on those counts.The 35-year-old son of former San Diego Chargers legend Kellen Winslow was acquitted of committing lewd conduct in front of Jane Doe 5 on a separate occasion.The jury was unable to reach consensus on rape and kidnapping charges involving a 54-year-old hitchhiker allegedly targeted last March in Encinitas, and a 17- year-old girl who was allegedly raped in 2003 at a Scripps Ranch house party. 1128

SAN DIEGO (CNS) -- Unemployment numbers continue to decrease across San Diego County from a high of 25% in May, a report released Thursday from the San Diego Association of Governments found.The region's unemployment rate is estimated to be 15.9%, the SANDAG report found, 1.8% lower than the previous week and 9.1% lower than this time last month.According to the report, the number of unemployed people in the county began to drop when Gov. Gavin Newsom announced the state was moving into Stage 2 of his four-stage reopening roadmap on May 8. The report also credits local politicians for getting people back to work."Elected officials in the San Diego region have worked aggressively to help businesses reopen as quickly as possible, which contributed to approximately 150,000 workers returning to work in the past month," a summary of the report said. "However, there are still roughly 270,000 unemployed people in the region (down from 425,000 in early May)."San Diego County moved into Phase 3 of reopening in early June, which allowed in-store retail, restaurants, manufacturing facilities, hair salons and barbershops, bars, zoos, movie theaters and hotels to resume operations with appropriate social-distancing rules in place. On June 19, nail and facial salons and tattoo and massage establishments were allowed to reopen.The unemployment rate of 15.9% in the region is still 50% higher than it was at the peak of the Great Recession -- 10.8% in 2009 -- which signals that there is still a long way to go to return to the unemployment levels recorded in March 2020, before the start of the public health crisis.The most affected ZIP Codes remain those in the southern and central part of the region. The five ZIP Codes still experiencing the highest unemployment rates are Golden Hill, College Area, City Heights, San Ysidro and Logan Heights. These areas have an average unemployment rate around 20%.The five ZIP Codes with lowest unemployment rates are Del Mar, Carmel Valley, Rancho Santa Fe, Chula Vista NE and Rancho Bernardo W. These areas have an average unemployment rate of around 12%. 2114
