Frost flowers on sea ice as a source of sea salt and their influence on tropospheric halogen chemistry

first_imgFrost flowers grow on newly-formed sea ice from a saturated water vapour layer. They provide a large effective surface area and a reservoir of sea salt ions in the liquid phase with triple the ion concentration of sea water. Recently, frost flowers have been recognised as the dominant source of sea salt aerosol in the Antarctic, and it has been speculated that they could be involved in processes causing severe tropospheric ozone depletion events during the polar sunrise. These events can be explained by heterogeneous autocatalytic reactions taking place on salt-laden ice surfaces which exponentially increase the reactive gas phase bromine (“bromine explosion”). We analyzed tropospheric bromine monoxide (BrO) and the sea ice coverage both measured from satellite sensors. Our model based interpretation shows that young ice regions potentially covered with frost flowers seem to be the source of bromine found in bromine explosion events.last_img

Changes in penguin distribution over the Antarctic Peninsula and Scotia Arc (Version 2.0)

first_imgRobust evidence highlights major shifts in the abundance and distribution of penguins (Adélie, chinstrap, gentoo, emperor, king, and macaroni) breeding on the Antarctic Peninsula and across the Scotia Arc in FAO statistical SubAreas 48.1 to 48.4. In SubArea 48.1, Adélies and chinstraps have declined throughout most of the western Antarctic Peninsula (WAP) to the north of Marguerite Bay. Adélies are stable or increasing in Marguerite Bay and to the south, and stable or increasing in the eastern Antarctic Peninsula. By contrast, gentoos on the WAP (48.1) and at the South Orkney Islands (48.2) are increasing and expanding their breeding range southwards; elsewhere, their populations are highly variable but not trending significantly. In SubArea 48.3, macaronis have experienced substantial declines while kings have increased. In SubArea 48.4, chinstraps and Adélies are stable. These findings highlight considerable spatial heterogeneity in species trends, and the importance of up to date census data to underpin work to predict and monitor future trends.last_img read more

Stennis (CVN 74) and the embarked Carrier Air Wing (CVW) 9 marked a milestone, May 5, with the deployment’s 5,000th arrested landing, or trap.John C. Stennis and CVW-9 have worked hard together through the workup cycle and put their lessons learned into practice on this deployment.“Five thousand traps is a huge accomplishment,” said Lt. Chris Jones, from Paintsville, Kentucky, the acting aircraft handling officer during the 5,000th trap. “It’s a testament to the hard work of the men and women on the flight deck putting in long hours day in and day out in the heat.”Lt. Shane Brady, from Annapolis, Maryland, assigned to the Vigilantes of Strike Fighter Squadron (VFA) 151, piloted the F/A-18E Super Hornet that completed the 5,000th arrested landing.“It was a series of fortunate events,” said Brady. “I didn’t even know I had made it until the maintenance guys told me the [commanding officer] had announced it.”Master Chief Aviation Boatswain’s Mate Jack Hudson, from Mexico, Missouri, the leading chief petty officer for the Air Department aboard John C. Stennis, said the trap reflected the hard work put into ensuring the safe launch and recovery of aircraft.“The crew has worked their butts off this deployment,” said Hudson. “They don’t have time to take a break… they’re highly energized and love what they do. It’s truly amazing.”Deployed in the Indo-Asia-Pacific, John C. Stennis is operating as part of the Great Green Fleet on a regularly scheduled 7th Fleet deployment.Ships sailing under the Great Green Fleet project are fueled by alternative fuel which is a mix of regular fuel and fuel made from waste beef fat provided by farmers in the U.S. Midwest.last_img read more

Oxford ACS wins ‘BAME Society of the Year’

first_imgThe Oxford African and Caribbean Society (ACS) has been named national ‘BAME Society of the Year’ at The Tab‘s Society of the Year Awards 2017/18.The Society topped the ballot with 295 votes, beating 12 other UK university groups. ACS’ award, given in partnership with Bloomberg, recognises groups “doing the most to support BAME communities at uni.”The Society said on its Facebook page: “We’re delighted to announce that your ACS has won its first national award!!…Thank you to everyone who voted for us.” ACS was the only Oxford society to be recognised in any category at the Awards.ACS vice president, Josh Tulloch, told Cherwell: “It’s a great honour to be recognised for our tireless efforts to maintain and expand the space for Afro-Caribbean students at Oxford on such a prestigious national level.“Going forward, we aim to take our pioneering, grassroots approach to access and outreach to thousands more students across the country.”Second behind ACS was Newcastle University’s BAME Network with 228 votes, while Reading’s Reading Marrow and Sussex’s South Asian Students’ Society took third and fourth places respectively.As part of their work, Oxford ACS organise the Annual Access Conference, the largest student-run access conference for students of African and Caribbean heritage. This is designed to support Year 12 students of African and Caribbean descent in making applications to Oxford.Earlier this academic year, ACS invited Stormzy, their person of the year, to attend. The purpose of this conference is “to demystify the Oxford application process for students and teachers”, while also raising “the academic aspirations of able students.”A spokesperson for the University of Oxford told Cherwell: “The University warmly congratulates the African Caribbean Society on its well-deserved success.“Together ACS members promote and celebrate African and Caribbean culture with fantastic energy and creativity. They are also constructive critics, extraordinarily good partners and exemplary ambassadors in the collegiate University’s vital outreach activities.“The ACS acts upon a deep commitment to helping the next generation of African Caribbean students, and in recent years the society’s advocacy, polished organisation and impact has been superb.“Oxford is a diverse university and this diversity underpins its success– but we know we have more to do to ensure that Oxford is fully inclusive and reflects wider society.“We strive to support and are working to see more black students gaining places here. We will not stand still.”Awards are also given to groups which have particularly contributed towards achieving greater gender, disability and LGBTQ+ equality respectively at UK universities.The winner of the gender category was Birmingham University’s Conservative group, while Sussex’s DragSoc was voted as doing the most to support the LGBTQ+ community. Birmingham’s Monday Night Club topped the category for groups supporting the disabled community.Societies featured in the awards will visit Bloomberg’s HQ for mentoring and for training sessions through Bloomberg’s diversity and inclusion communities. They will also be profiled by The Tab.Oxford ACS’ recognition follows several recent cases which highlight the need for work to be done in improving Oxford as an accessible and inclusive environment for BME students.Last term, Cherwell reported that only two black students gained a first in 2016-17 finals exams, meaning only 8% of black students received a first compared to 36% of white students.In October last year, David Lammy MP accused Oxford of “social apartheid” after figures were released showing that ten out of 32 colleges failed to admit any black A-level students in 2015.last_img read more

Do more on local level to protect kids

first_imgCategories: Letters to the Editor, Opinion On Feb. 28, 2018, you published a letter I wrote in which I suggested that debating gun control and the Second Amendment will not protect our children from someone intent on committing mass carnage within our schools. Here we are, only months later, mourning the death of more children. Why? Because we are unrealistic when we erroneously believe the state and/or the federal government are expediently functional enough protect our children. They can’t do so. Where does the responsibility then lie? With us, the parents of our precious children. Children that we send off to school every morning and pray that they come home safely at the end of the day. Responsibility is at the local school district level. We must strongly demand that more than just superficial protection be put in place. While ideological positions are being debated, our children have been and still are left unprotected. As stated on Feb. 28, it’s not if, but when, another tragedy will occur.Carl LaMalfaSchenectadyMore from The Daily Gazette:Schenectady High School senior class leaders look to salvage sense of normalcySchenectady, Saratoga casinos say reopening has gone well; revenue down 30%Troopers: Schenectady pair possessed heroin, crack cocaine in Orange County Thruway stopEDITORIAL: Urgent: Today is the last day to complete the censusSchenectady department heads: Budget cutbacks would further stress already-stretched departmentslast_img read more

Locked-down Spain celebrates Holy Week with music and humor

first_img‘Really struggling’ Police have joined in on the act. In Seville, two municipal police cars drove slowly in front of a church, stopping at times before moving on just like Holy Week floats do, to the tune of religious music.With processions called off, many religious brotherhoods have focused on helping fight the coronavirus pandemic that has claimed more than 14,500 lives in Spain, one of the highest tolls in the world.In the northern city of Valladolid, 20 brotherhoods donated 1,000 euros ($1,085) each to buy protective equipment and other urgently needed supplies for healthcare workers, said local association leader Isaias Martinez Iglesias.Pablo Alen of Seville’s Carreteria brotherhood said it would take a “relatively big” economic hit this year, because it will not collect any donations from participants during the traditional Good Friday parade.With less money coming in the brotherhood’s priority is to focus on its charity work such as a soup kitchen, so it will postpone planned restorations of its religious artworks, he added.”There are people who are asking for help, who are really struggling,” Alen noted. In the week leading to Easter Sunday, hundreds of colorful processions featuring penitents in cone-shaped hoods and centuries-old religious floats traditionally flood the streets of villages and cities across Spain.But with a nationwide lockdown in place to curb the spread of COVID-19, Spaniards are finding ways to mark Holy Week from their homes, by blasting religious music from their balconies or viewing videos of last year’s parades.In the western city of Salamanca, the association of religious brotherhoods that organizes processions is posting pictures on social media of religious icons that would normally be paraded through the streets at the hour that would have taken place. “And on our YouTube channel we are posting a video of the procession from last year,” association president Jose Adrian Cornejo told AFP.There is one part of the processions that can still go ahead — the singing of “saetas”, short, flamenco prayers sung from balconies which are especially popular in the southwestern region of Andalusia.Saetas are usually sung as effigies of Jesus Christ and the Virgin Mary are carried past, but this year they are being performed to empty streets.Type in “saetas of confinement” on YouTube and several events come up, including one by Alex Ortiz in Seville — which is not staging Easter processions for the first time since 1933 —  who sings of a “sad spring” without “drums or bugles” in the streets. Topics : Toilet paper roll icon Pablo Murillo, a Catholic father of four, said he was celebrating Holy Week with “more seclusion”.He was supposed to take part in a Palm Sunday procession but instead listened to the traditional “marchas” — special musical compositions featuring wind instruments and drums that accompany the floats — at home with his sons.”My oldest who is 12 puts the speakers in the bathroom, and takes a shower while listening to the Holy Week ‘marchas’,” Murillo said.He lives near Seville’s largest hospital and every night many neighbors blast “marchas” from their balconies after applauding healthcare workers at 8:00 pm, as people are doing across Europe.Some people have violated the lockdown rules to celebrate Easter, meanwhile. In Puerta de Segura, a small town of whitewashed houses in Andalusia, several people left their homes to imitate a procession, with one man carrying a drum and a woman wearing a blanket wrapped around her head like the veils depicted in the statue of the Virgin Mary, images on Spanish TV showed.In the nearby town of Porcuna nine women dressed in black and carrying candles walked through the streets, while in the northern city of Palencia two men dressed in a tunic and hood held a mock procession by carrying an “icon” made of toilet paper rolls.last_img read more

Trump tests positive for Covid, upending US election

first_img The news detonated a political bombshell a month before election day.The first immediate consequence was cancellation of a Trump campaign rally meant to take place in Florida later Friday.Badly behind in the polls against Democratic challenger Joe Biden ahead of Nov.3, Trump has been using large rallies – where most people go without masks – to try to change the subject from his much criticized response to the coronavirus pandemic.Just Thursday he said in a speech to a New York charity event: “The end of the pandemic is in sight and next year will be one of the greatest years in the history of our country.” Topics : But now the leader who has repeatedly cast doubt on the seriousness of the virus – despite more than 200,000 Americans already dying – has become the world’s highest profile patient, proving that all the resources of the White House could not prevent the risk.Biden, who has made criticism of the Republican’s coronavirus response his key issue, made no immediate statement about the president’s health after the news broke.Technically obese and in his 70s, Trump is in a higher-risk category for coronavirus patients.Trump’s official physician, Sean Conley, said in a statement that the president and his wife “are both well at this time.””They plan to remain home at the White House during their convalescence,” he said. However, “I expect the president to continue carrying out his duties without disruption while recovering.”Trump’s positive test was more than a PR disaster for a president who has staked everything on trying to persuade Americans that fears of the virus are overblown.There were concrete, instant impacts to his campaign strategy, particularly throwing into doubt the future of his signature rallies.The events, which Trump says prove his true political strength better than the dismal opinion polls, bring together thousands of people, often without masks and sometimes in contravention of local rules.All that is now on hold, at least for the immediate future, and with the clock ticking rapidly down on the election.In addition to canceling the Florida trip, it looked certain that Trump would have to abandon a trip scheduled for this weekend in Wisconsin, another battleground. He had also been expected to travel frequently next week, including longer distances to western states.A second televised debate with Biden is scheduled for Oct.15.The news came right after one of Trump’s closest advisors, Hope Hicks, was reported Thursday to have come down with the virus.Hicks, 31, traveled with Trump to Cleveland for his first debate with Biden on Tuesday. She was with him again for a campaign rally in Minnesota on Wednesday.With Hicks sharing Trump’s Air Force One plane and the even more cramped confines of the Marine One helicopter, speculation immediately erupted that Trump and possibly many others in his close entourage were exposed.Despite Hicks’ diagnosis, Trump took another Air Force One trip on Thursday to meet with donors in New Jersey.It was only late Thursday that Trump confirmed media reports about Hicks while giving an interview to Fox News. He announced that he had been tested but did not say whether he had received the results.”You know I spend a lot of time with Hope, and so does the first lady,” Trump said.Hicks is the most senior White House aide announced to have contracted Covid-19.center_img President Donald Trump has tested positive for Covid-19, upending the already tense US election, but was described by his doctor on Friday as feeling “well” and able to perform his duties while quarantining.Trump, 74, first announced on Twitter that he and First Lady Melania Trump, 50, had tested positive.”We will get through this TOGETHER!” he wrote.last_img read more
