Variable crustal thickness beneath Thwaites Glacier revealed from airborne gravimetry, possible implications for geothermal heat flux in West Antarctica

first_imgThwaites Glacier has one of the largest glacial catchments in West Antarctica. The future stability of Thwaites Glacier’s catchment is of great concern, as this part of the West Antarctic Ice Sheet has recently been hypothesized to already be en route towards collapse. Although an oceanic trigger is thought to be responsible for current change at the grounding line of Thwaites Glacier, in order to determine the effects of this coastal change further in the interior of the West Antarctic Ice Sheet it is essential to also better constrain basal conditions that control the dynamics of fast glacial flow within the catchment itself. One major contributor to fast glacial flow is the presence of subglacial water, the production of which is a result of both glaciological shear heating and geothermal heat flux. The primary goal of our study is to investigate the crustal thickness beneath Thwaites Glacier, which is an important contributor to regional-scale geothermal heat flux patterns. Crustal structure is an indicator of past tectonic events and hence provides a geophysical proxy for the thermal status of the crust and mantle. Terrain-corrected Bouguer gravity disturbances are used here to estimate depths to the Moho and mid-crustal boundary. The thin continental crust we reveal beneath Thwaites Glacier supports the hypothesis that the West Antarctic Rift System underlies the region and is expressed topographically as the Byrd Subglacial Basin. This rifted crust is of similar thickness to that calculated from airborne gravity data beneath neighboring Pine Island Glacier, and is more extended than crust in the adjacent Siple Coast sector of the Ross Sea Embayment. A zone of thinner crust is also identified near the area’s subaerial volcanoes lending support to a recent interpretation predicting that this part of Marie Byrd Land is a major volcanic dome, likely within the West Antarctic Rift System itself. Near-zero Bouguer gravity disturbances for the subglacial highlands and subaerial volcanoes indicate the absence of supporting crustal roots, suggesting either (1) thermal support from a warm lithosphere or alternatively, and arguably less likely; (2) flexural support of the topography by a cool and rigid lithosphere, or (3) Pratt-like compensation. Although forward modeling of gravity data is non-unique in respect to these alternative possibilities, we prefer the hypothesis that Marie Byrd Land volcanoes are thermally-supported by warmer upper mantle. The presence of such inferred warm upper mantle also suggests regionally elevated geothermal heat flux in this sector of the West Antarctic Rift System and consequently the potential for enhanced meltwater production beneath parts of Thwaites Glacier itself. Our new crustal thickness estimates and geothermal heat flux inferences in the Thwaites Glacier region are significant both for studies of the structure of the broader West Antarctic Rift System and for assessments of geological influences on West Antarctic Ice Sheet dynamics and glacial isostatic adjustment models.last_img read more

Tropical Storm Bertha Named, Not Likely to Affect Ocean City

first_imgAn early model for the probability of tropical storm force winds (39 mph or greater) from Tropical Storm Bertha. Yellow represents a 40 percent chance.The 2014 hurricane season in the Atlantic Ocean has its second named system, but Tropical Storm Bertha is not likely to affect Ocean City in any significant way.The projected track of the storm takes Bertha up the Atlantic Ocean parallel to the East Coast of the U.S.It’s a tropical storm track that often creates the big and clean waves that surfers crave, but Bertha could be too weak and too distant to generate much surf — though the long-range forecast is still uncertain. Some models suggest a 3- to 5-foot swell on Wednesday.At 8 a.m. Friday, Bertha had sustained winds of 45 mph and was headed toward Barbados and the Caribbean. The National Hurricane Center does not anticipate significant strengthening in the next 48 hours.But as the storm turns north on a projected arc over the open water of the Atlantic Ocean, it could intensify, according to the Hurricane Center forecast.Bertha would pass Ocean City far out to sea on Tuesday or Wednesday, according to the early models for the storm track.__________Sign up for OCNJ Daily’s free newsletter and breaking news alerts“Like” us on Facebooklast_img read more

News story: Updated Fire and Rescue National Framework for England

first_imgThe revised Fire and Rescue National Framework follows a consultation on proposed changes earlier this year, required by the Fire and Rescue Services Act 2004. 71 responses were received overall, with contributions from: the NFCC; the majority of FRAs; the Local Government Association and the Fire Brigades Union among others.Minister for Policing and the Fire Service Nick Hurd said: The national framework provides the basis for how fire and rescue services in England should operate. The revised version we have published today should support them becoming more accountable, effective and professional than ever before and embed the government’s reform programme. The order giving effect to the revised framework has been laid before Parliament today (8 May) with the framework coming into force on 1 June 2018.The Hackitt Review and Grenfell Inquiry may make recommendations which need to be reflected in further revisions to the national framework. We will update as required to ensure any recommendations are captured. changes in guidance to reflect recent legislative changes to allow mayors and police and crime commissioners to exercise the functions of an FRA changes to encourage commercial transformation by FRAs, leading to further collaboration, innovative thinking and sharing of best practice a workforce section which outlines how FRAs should support and develop their workforce provisions supporting the development and delivery of professional standards for FRAs, addressing the current lack of co-ordination of standards across England’s fire services new guidance on how fire and rescue authorities should work with the National Fire Chiefs Council (NFCC) and Her Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) The Fire and Rescue National Framework embeds the government’s fire reform agenda, alongside provisions in the Policing and Crime Act 2017.

Press release: Foreign Secretary pledges to do everything possible to protect wild animals

first_img Media enquiries Follow the Foreign Office on Twitter @foreignoffice and Facebook Further information Follow the Foreign Office on Instagram, YouTube and LinkedIn Foreign Secretary, Jeremy Hunt, said: In the last 5 decades, the world has lost nearly 60 percent of its vertebrate animals. In case you believe that is just another statistic, think about what it means. The magnificent wildlife that humanity has inherited – the animals that enliven our imaginations, enhance the beauty of the world and provide livelihoods for millions of people – are disappearing with terrifying speed.We have lost two thirds of Africa’s elephants since the 1970s. We are down to the last 80,000 giraffes and the final 20,000 lions. The world’s tiger population has dropped by 95% in the last century. If we go on like this, our grandchildren may only know of these animals from David Attenborough documentaries. So today, I will open a conference in London attended by 80 countries on how to combat the illegal wildlife trade.The criminal gangs who smuggle horns and tusks pose one of the greatest threats to the survival of wildlife. They target some of the poorest countries in the world, spreading corruption and depriving governments of desperately needed revenues that could be used for schools and hospitals. The World Bank estimates that governments lose as much as $15 billion (£11 billion) every year because of illegal logging. And the same criminal networks that traffic the body parts of wild animals may also deal in guns and drugs and people. This week, I have joined Penny Mordaunt, the International Development Secretary, to announce a new British initiative to target the traffickers by helping countries in Africa and Asia to launch investigations and seize assets. We are sending more British diplomats to Africa, including experts on combating the illegal wildlife trade. Last year, our Parliament passed the Criminal Finances Act, strengthening the British Government’s powers to combat money laundering and freeze unexplained wealth. Since then, we have placed another law before Parliament that would ban domestic ivory sales. We will also contribute £250 million to the United Nations Global Environment Facility by 2022. As part of this, the Global Wildlife Programme has worked with Kenya on a new law imposing tougher punishments for wildlife crimes, including life imprisonment for anyone caught smuggling the body parts of an endangered species. We are using our aid budget to help the UN Office of Drugs and Crime to strengthen the ability of developing countries to enforce their laws against the wildlife trade and improve their investigative skills. When laws are enforced and smugglers prosecuted, wildlife populations can and do recover. The number of wild tigers in Nepal, for example, has doubled in the last nine years. The London conference will be the biggest international gathering of its kind ever held. My aim is for Britain to do everything possible to protect wild animals for the sake of our grandchildren. If we failed to act, quite simply we would never be forgiven. Follow the Foreign Secretary on Twitter @Jeremy_Hunt For journalists Email [email protected]last_img read more

Tom Morello, STS9, Graham Nash, 100+ Other Artists Sign Open Letter Supporting Net Neutrality

first_imgMore than 150 entertainers have come together in support of net neutrality, signing an open letter to Congress calling to stop the FCC’s planned vote to end net neutrality protection on Dec. 14. The list of artists that cosigned the letter include Tom Morello (Rage Against The Machine, Prophets of Rage), Michael Stipe (R.E.M.), Incubus, Atmosphere, Bassnectar, Charlie Hunter, Emancipator, Graham Nash, Gramatik, STS9, Talib Kweli, and The Glitch Mob, among many others.On a party-line vote, the FCC voted for the first step of Chairman Ajit Pai’s plan to hand control of the internet to giant telecom corporations. Not only is ending net neutrality a threat to freedom of speech online, it means Comcast and Verizon can demand companies and consumers pay shakedown fees for decent speeds – those who don’t pay get pushed into “slow lanes.”Join Us In The Fight For Net Neutrality! Find Out Why It Matters & How To Get Involved HereAs the “Fight For The Future” letter states, “The medium that allows us to be great artists is under threat. Without a free and open internet, so much music, writing, film, art, culture, passion, and creativity would be lost. or the artists of the future, and the culture of the future, we will not be silent.”The letter continues, “A few corporations will have control over what you see and hear, while independent and up-and-coming artists’ ability to make a living will be devastated,” the letter reads. “Without net neutrality there will be less awesome art. Period. The open Internet lets artists reach each other and audiences across the world in unprecedented ways. We are able to collaborate, learn, improve our worlds, participate in our society, and bring the things we love to people who are moved by them. Freedom of speech and freedom of expression are guaranteed by our constitution, and we demand that such freedoms continue online. Net Neutrality is essential to our democracy.”You can sign a petition officially stating your opposition to the FCC’s plan to abolish net neutrality here.

Harvard College Librarian, Nancy Cline, to retire

first_imgAfter nearly 15 years of exceptional service, Nancy M. Cline, the Roy E. Larsen Librarian of Harvard College, will retire at the end of this academic year.Cline’s long career at Harvard is distinguished by many notable accomplishments. In 1996, she began her current appointment overseeing the operations of the major libraries and units within the Harvard College Library. During her tenure at Harvard, Widener Library has been completely renovated; support for collections preservation has increased; and Harvard’s Library Digital Initiative has been launched.Outside of Harvard, Cline is regarded as a national leader in the library profession and currently serves on the MIT Corporation Visiting Committee for the Libraries, the University of Miami Libraries Visiting Committee, and the Cambridge University Board of Electors to the Librarianship. She is also a member of the ITHAKA Board of Trustees. She has spoken and published on numerous topics including digital libraries, intellectual property, preservation, security, and library administration.In 2006, Cline received the Hugh C. Atkinson Memorial Award, which recognizes an academic librarian who has made significant contributions in the area of library automation or management and has made notable improvements in library services or research.“I am deeply grateful to Nancy for her leadership and her exemplary service to Harvard,” said Faculty of Arts and Sciences (FAS) Dean Michael D. Smith. “The new vision for the Harvard Library we are now embracing, and the profound and positive changes this vision will bring, are an important part of her legacy, in keeping with the many advances she has forwarded over her long career here. Her contributions to FAS and the University will endure for generations to come, affecting us all for the better.”last_img read more

Business competition offers prize

first_imgThe search is on for the next great idea. Now in its 12th year, the McCloskey Business Plan Competition invites students, alumni and faculty to submit both profit and nonprofit business ventures, competing for a grand prize of $20,000. Laura Hollis, director of the Gigot Center for Entrepreneurial Studies, said the competition is on the lookout for unique ventures, especially those geared toward addressing social issues. “There are no impediments and any reason not to enter isn’t good enough as far as I’m concerned,” Hollis said. “If you’ve ever said somebody ‘oughta’ make something, you have an idea. What’s there to risk?” She said the best way to approach the competition, or any business venture, is to consider what problems exist and create innovative solutions to those problems. “That’s what it’s really about — why people are so riveted by Steve Jobs in his passing,” Hollis said. “It’s people who don’t let circumstances tell them no. They aren’t bound by the way things are always done.” Registration for the competition is now open, Hollis said, and the cutoff for submissions is November 7. The competition involves three stages: an open call for submissions, a semifinalist competition and finalist presentations in April. “Last year, we had 120 submissions,” Hollis said. “67 moved on from the first stage and were then narrowed to 12 semifinalists. The finalists then gave a presentation before the judges in April.” The Ideas Challenge, which focused on entrepreneurship, kicked off the competition in September, she said. “They had to stand up for 60 seconds and say, ‘Here’s my idea,’” Hollis said. “That’s honestly the hardest part for most people.” Hollis said the competition seeks ventures that have the potential to make both social and commercial impacts. “Last year we fused together the McCloskey Business Competition and the Social Venture Competition,” she said. “This gets away from the notion that commercial and social ventures are completely different. We want commercial ventures to have more social impact and social ones to have a strong sense of fiscal sustainability.” In addition to fusing the two competitions, the Gigot Center also streamlined the competition’s process, she said.  They decided to abandon a traditional 20-page paper on speculative sales, required in previous years, opting instead for a process that cultivates confidence and experience. “Most collegiate ventures are in their early stages so we’ve taken on more of a handholding process at each step,” Hollis said. “We’re also beefing up a lot of in-kind support prizes which are more helpful for them than just handing them a check.” While only a few are designated winners in the McCloskey Competition, it can act as a launch pad for other participants, Hollis said. Hollis said competitors have worked in the past to answer pervasive issues in health and medical, technology, social plans, literacy and several other topics. “Can you come up with something that solves a problem or meets a need?” Hollis said. “When push comes to shove, you go about answering it and that’s more important than the prize.”last_img read more
