Scientists from all over the world recently returned home after the largest Arctic expedition to date.The Polarstern, a German ice breaker, housed hundreds of scientists who spent time over the past year to do research in the Arctic.“The MOSAiC Expedition is an expedition to the central Arctic. We took a ship, an icebreaker ship, and froze it in the arctic sea ice. It stayed there and drifted with that ice for a full year and that ship served as a platform for doing all kinds of research to understand the changing Arctic sea ice and the implications that has on the arctic system and global system,” Matthew Shupe, scientist and co-coordinator of the MOSAiC Expedition, said. He is also a professor at the University of Colorado Boulder.“MOSAiC really represents the largest expedition to the arctic ever,” he said. “MOSAiC is, I would say, very photogenic. It’s really compelling and captivating to all kinds of audiences.”But the data collected and changed observed during the rip serve a larger purpose than just beautiful, picturesque nature videos and photos.“The Arctic is changing. The sea ice is changing and we knew this,” Shupe said. “But when we went there the ice was thinner than we expected.”That change impacts a number of things. Shupe said as the Arctic changes, it’s opening for business. “It’s opening for cargo transportation, it’s opening for tourism.”It’s an indicator of larger changes as well.“Can potentially affect our weather, you can imagine the large scale circulation of our globe is dependent on things like a cold North Pole versus warm tropics and that affects the large scale circulation,” he said.The data these scientists collected over the span of a year will be used for global climate and weather prediction models.“These models rely on information, we have to understand the Earth's system in order to model it,” Shupe said.Hundreds of scientists from 37 different nations, all focusing on different projects, funded in part by U.S. tax dollars.“This is funded by the national science foundation, department of energy, NOAA, NASA, these are institutions that are funding this kind of research to understand arctic change and how it affects all of us," Shupe said.Next year, you’ll be able to experience the Arctic, too.“This planetarium film is an educational documentary about the MOSAiC Expedition,” said Lianna Nixon, a filmmaker, who spent a few months aboard Polarstern. She documented the expedition for a few months to bring the Arctic to everyone. “What we wanted to do was really express what kinds of science people were doing in the field and take that into your local planetarium.”The 30-minute film will be available at planetariums as soon as next year -- a 2D version will also be available.“The Arctic impacts all of us no matter where we live. The polar regions drive a lot of our global climate systems,” Nixon said.Expeditions to the Arctic have been happening for more than 100 years, but this new data collected by MOSAiC will be used in the science community for years to come.“MOSAiC is building on this history of expeditions to the Arctic,” Shupe said. 3131

SANTA ANA (CNS) - Two more people in Orange County have tested positive locally for the novel coronavirus, health officials said today, but federal test results are still pending to confirm the diagnoses.According to the Orange County Health Care Agency, the cases are a man in his 60s and a woman in her 30s who had recently traveled to countries with widespread outbreaks of what is officially known as COVID-19. The pair tested positive in Orange County, but test results were sent to the U.S.Centers for Disease Control and Prevention to confirm the results. "The more you look for something, the more likely you are to find it," said Dr. Nichole Quick, the county's health officer. "Now that our Public Health Laboratory is able to perform COVID-19 testing, we expect to see more cases here in Orange County. Our residents should take everyday precautions to prevent the spread of respiratory illnesses like covering your coughs and sneezes, avoiding touching your face, and washing your hands frequently."Another person in the county who contracted the virus earlier this year has fully recovered.The news comes as organizers of the second biggest annual convention in Anaheim announced the postponement of the event due to concerns over the virus. Natural Products Expo West officials plan to discuss a new date for the convention in Anaheim later this year.There have been nine deaths from coronavirus in the United States, in Washington state. Worldwide, roughly 93,000 cases of COVID-19 have been reported, and more than 3,100 deaths. 1552
SAN FRANCISCO (AP) — The Coast Guard is investigating what caused a ferry boat to crash twice into docks at San Francisco's famed Ferry Building, slightly injuring two people aboard.Coast Guard spokesman Chris Shih says investigators are looking into mechanical issues and other factors that led to Friday's crash. The agency regularly inspects the ferries.A Golden Gate Ferry spokeswoman says the boat was traveling from Larkspur and carrying 53 passengers when it struck an outer berth before bumping into another dock.The vessel's hull was damaged when it struck the concrete promenade and knocked a guardrail. The Coast Guard says there were reports of two minor injuries that didn't require treatment beyond first aid.Witness Tiffany Dennis says the crash set off panic among a crowd of people dining and shopping at the waterfront attraction. 856
