Weddell Sea abyssal sediments a record of Antarctic Bottom Water Flow

first_imgDeep circulation in the Weddell Sea is a clockwise gyre, with bottom water formed by mixing along the southern and western margins. Most Antarctic Bottom Water originates here, leaving the Weddell Sea to the east (depths > 4500 m) or to the north (depths 16 m/Ma. Sediments from the deep Weddell Basin are hemipelagic muds with ash laminae and (mainly in the centre of the gyre) distal turbidites derived from the southwest. Thin debris flows occur near seamounts. The hemipelagic muds become coarser from the centre to the edge of the gyre. Winnowing by strong bottom currents is localised along the northern margin of the basin. The absence of diatoms from the Weddell Basin sediments may result from dissolution as well as low productivity. Sediments from Jane Basin consist of alternating diatomaceous and barren hemipelagic muds, considered to represent interglacial and glacial conditions respectively. The diatomaceous sediments contain more silt, suggesting that bottom water flow increases during interglacial periods.last_img read more

Challenging property market to continue, warns Hunters boss

first_imgHunters’ Chief Executive Glynis Frew (pictured, above) has warned investors that the challenging property market is unlikely to improve “in the foreseeable future” and that industry consolidation will continue.The comment are made by her within its half year results published this morning. They reveal a perky performance from its lettings division,  a net gain of three new branches to its network but flat-lining overall revenue.Hunters says its performance has been ‘robust’ given the grim market conditions in many parts of the UK, particularly for property sales which Hunters says have dropped by 9% so far this year.Despite this its franchised offices paid Hunters 2% more income while cost savings pushed up its profits by 7%.Property marketBut the property market’s difficulties aren’t far away within its results. Although Hunters opened eight new branches including the conversion of six existing businesses and two cold starts, it has just three more branches than a year ago.Other highlights of its half year include the purchase of 11 lettings portfolios via its recently-launched franchisee financing programme and a 14% increase in lettings income overall.“Hunters is underpinned by our strategy to grow and develop the franchise network and we are bolstered by the pipeline of prospective franchisees interested in joining Hunters,” says Glynnis.“We are especially encouraged [by] the increase in strength of prospects we have registered reinforcing our view, especially in this environment, of the comparative benefits of joining the Hunters network.“The continuing work and support displayed by our staff and the franchise network is a great credit to the Group. I offer, on behalf of the Board, our gratitude to everyone that has been involved.” Glynis Frew Hunters half year results 2018 September 6, 2018Nigel LewisWhat’s your opinion?

Commentary: Trump Didn’t Do It And The Earth Remains Flat

first_imgmichael By Michael LeppertMichaelLeppert.comThe camouflage of a zebra is confusing to both humans and lions. To humans, those stripes don’t seem to be a disguise of any kind. But to lions, who are zebra’s main predator in the wild and are colorblind, those black and white stripes actually do blend in nicely with the tall grass on an African plain.Of equal or greater value though, is the visual confusion zebra stripes create when they are in a herd. A lion sees the herd as a large amorphous blob as the stripes of each animal blend with each other and the backdrop of the grass. Even as smart as lions are, they often cannot come up with an effective plan of attack with the disorienting view in front of them.Yes, in today’s first metaphor, Republican members of the U.S. Senate have become very much like a herd of zebras.It was no surprise that President Donald Trump was acquitted by the U.S. Senate of two articles of impeachment on Wednesday. There were only rumors of cracks in the fortress the president has built with today’s congressional Republicans that might give optimism to those who believe a vote to convict him was the only rational thing for any Senator to do.In the end, Sen. Mitt Romney of Utah was the only Senate Republican who had the courage to vote for the conviction.“What is the right thing to do? What does the Constitution demand?” were questions Romney asked himself. He voted to convict the president on the charge of abuse of power. “I think the case was made. It was about as egregious an assault on the Constitution as can be made.” In a career that easily could have been described as one filled with decisions made for political expediency, this is a move by a man who doesn’t need or want to stand for that any longer.What would the politically expedient thing even be for a senator elected to a six-year term in 2018? Romney will never appear on a ballot with Trump, even if he runs for reelection. He will be 77 on Election Day in 2024. He has an abundance of personal wealth. There are not immediate electoral consequences for the freshman senator from Utah, which should give him the political freedom to make the choice he made on impeachment.Back home in Indiana, Romney’s situation sounds a little like what is facing the Hoosier state’s freshman senator, Mike Braun. He will be 70-years old if he runs for reelection in 2024. He too has an abundance of personal wealth. Braun doesn’t need the job, and more importantly, he doesn’t need Trump. But he sure acts as he does.On Jan. 22, Braun tweeted out an exchange he had with a reporter, who asked if the president’s withholding of military aid to coerce a foreign nation to investigate a political rival is okay. His response: “No, I’m not saying that’s OK. I’m not saying that’s appropriate. I’m saying it didn’t happen.”Wow. Braun is taking the position that the piles of evidence that show this is exactly what happened, didn’t. He is not telling Hoosiers that what the president did is not impeachable. He is not telling us that it is being mischaracterized. He is saying that what the president admitted to doing simply did not happen.And in other Senate news, it turns out the Earth actually is flat. I’m sure the zebras on that African plain would agree.Political spin is an interesting exercise. There has been an overload of it with regard to the impeachment saga that ended this week. But this is simply dishonest. Of course, President Trump did it. There is some limited legitimacy to a debate about whether it is worthy of him being removed from office and whether the judicial branch should have been engaged more extensively in obtaining witnesses and documents. But there is no rationality behind the position that “it didn’t happen.”It’s the kind of statement that should make a senate press secretary cringe and immediately look to soften. In this case, though, it was tweeted out with pride.Mitt Romney violated the zebra rule by breaking away from the herd. He knew the lions waiting to pounce would race across the flat earth and maul him into dinner. His calculation was that for him, that mauling mattered less than his personal integrity and his oath as a senator and juror.For Braun, I’m going to have to dig deeper for a metaphor that works. I’m truly at a loss.FOOTNOTE: Michael Leppert is a public and governmental affairs consultant in Indianapolis and writes his thoughts about politics, government and anything else that strikes him at MichaelLeppert.com.This article was posted by the City-County Observer without bias, opinion of editing.

Press release: Major new multi million pound satellite investment deal for the UK

first_imgNotes to Editors: Major initiatives for the UK Space sector include the £99m National Satellite Test Facility at Harwell, the £92m to develop options for a UK alternative to the Galileo satellite navigation project, the £31.5m to support the development of the proposed spaceport in Sutherland in Scotland, and the UK’s continuing commitment to being a leading player in the European Space Agency. A new multi-million-pound deal by European businesses Eutelsat Communications and Airbus Defence and Space for two new communication satellites will see components and major parts assembled in the UK before final assembly is completed in Toulouse, France.Components and major parts of the assembly will be built in the UK under the contract signed today (Monday 19 November) between satellite operator Eutelsat and aerospace manufacturer Airbus, Business Secretary Greg Clark announced.The deal, worth hundreds of millions of pounds, between Eutelsat, one of the world’s top three providers of TV broadcast signals and Airbus is a huge vote of confidence in the UK expertise in the space industry, benefitting 500 high skilled workers involved in Eutelsat projects.The new investment means Airbus sites in Portsmouth and Stevenage will manufacture key components of the two new satellites for Eutelsat, which will feature a brand-new electric platform to bring down size and cost, while boosting performance.Eutelsat is to replace its three existing satellites with two new ones set to launch in 2021. Today’s announcement means that 6 out of 7 of the company’s next satellites will be partially built in Britain, representing inward investment of up to €40 million per year.Business Secretary Greg Clark said: UK expertise has contributed significantly to the build of 23 of Eutelsat’s 38 satellites currently in orbit.Eutelsat CEO Rodolphe Belmer said: I am delighted to sign this agreement with Airbus to build two new state-of-the-art satellites, cementing the long-standing partnership between our two companies. The agreement will see the manufacture of key parts of the new satellites at Airbus’ facilities in Stevenage and Portsmouth. These satellites will renew the in-orbit assets at HOTBIRD, Eutelsat’s largest video hotspot, ensuring our continued support to global broadcasters in delivering high quality video content and services throughout the UK and Europe. We are impressed with the ongoing expansion of the UK space sector, particularly its growing industrial capabilities and development of cutting-edge technology, and we will continue to rely on the UK’s ability to build and deliver world-leading spacecraft. I am grateful for the support of the UK government and UK Space Agency, both of whom recognise the strong commitment Eutelsat has made to the UK over many years. Airbus’ telecommunication satellite technology developed in the UK has been key to this significant contract win. UK Space Agency support for the ESA ARTES programme has enabled Airbus in the UK to develop world leading technology for the world’s leading satellite operators. The UK Space Agency is helping industry to develop new technologies, infrastructure and services as part of the government’s modern Industrial Strategy.center_img The Airbus UK facilities in Portsmouth and Stevenage will build the entire communications payload, platform structure, propulsion subsystem, antennas and various mechanisms for the satellites. Airbus employs over 3,000 space engineers in the UK.Colin Paynter, Managing Director, Airbus Defence and Space UK, said: The build of an electric propulsion system for another new Eutelsat satellite known as KONNECT was recently completed by Thales Alenia Space in Belfast, demonstrating the growing presence of space across the UK. This investment is a significant vote of confidence for the UK’s world leading space industry. The UK is already a world-leader in developing satellite technology, with a 40 per cent share of the global export market of small satellites and building major parts for one in four of the world’s commercial telecommunications satellites. This new deal builds on the recent announcement, as part of our Industrial Strategy, that the UK is investing in, and building, its first proposed spaceport in Sutherland. The Spaceport will further develop our expertise and capabilities in the space sector enabling us to launch small satellites. Through our Modern Industrial Strategy, we are increasing the R&D budget to its highest level ever, building on our commitment to this sector and our world leading science base. This deal demonstrates that science, innovation and business has no borders. Eutelsat and Airbus invest millions in new satellite components and assembly in the UK Deal will support hundreds of high quality jobs in Portsmouth and Stevenage and thousands of jobs in the supply chain A year since the launch of the modern Industrial Strategy, this deal represents a further vote of confidence in the UK’s future economy and growing space industry Eutelsat QUANTUM the first software defined satellite, able to adapt to new demands in coverage, bandwidth, power and frequency configurability simply by being reprogrammed from the ground. Its phased array antennas will be able to shape the broadcast footprint as required – unlike a fixed standard reflector on most telecommunication satellites. It will also be partially built by Airbus in Portsmouth and Stevenage. The UK Space Agency is part of the Eutelsat QUANTUM Public Private Partnership through the ESA participation.last_img read more

Know your gnomon

first_imgThe story of Donner Professor of Science John Huth’s interest in primitive navigation techniques began with a body. Two bodies, actually.On his way to do some kayaking off Cape Cod a couple of summers ago, he was stopped by the harbormaster, who told him that two young women had gone missing the day before. They too had gone out in kayaks — neither with a compass — and told their boyfriends that they would return in only 15 minutes. After an hour with no sign of the women, authorities began a search and rescue operation. The next day, one body was found. The other was never recovered.“These young ladies were 19 and 20 years old, college students,” he said. “I actually have two students in college myself. If you read it in the newspaper, you might say, ‘What a shame. That’s horrible,’ and then turn the page. But having been out there at the same time, in the same conditions, it became harder for me to take.”In response to the tragedy, Huth, a physics professor who can often be found working at the Large Hadron Collider at the CERN complex in Switzerland, developed his “Primitive Navigation” class, first as a Freshman Seminar, then as a General Education course. The professor gave the families of first-year students a one-hour overview of the course Oct. 14 as part of the annual Freshman Parents Weekend program of lectures, tours, and open houses.Huth told parents that the goals of the course were not only to teach students practical skills that could one day save their lives, but also to help open up their senses to the natural world.“The people around you are relatively closed down, because we aren’t trained to notice [the natural environment],” Huth told his students. “And yet there’s a huge amount of information that’s right at the tips of our fingers that we’re tuning out.”To get the course material to stick with students, Huth designed “Primitive Navigation” as a combination of classroom learning and hands-on outdoor activities. In class, he taught students that common measures of distance grew out of human experience.To get the course material to stick with students, Huth designed “Primitive Navigation” as a combination of classroom learning and hands-on outdoor activities. In class, he taught students that common measures of distance grew out of human experience. The word “mile,” for instance, comes from the Latin “mille pacem,” or “1,000 paces.” Outside of class, Huth had students find their bearings — literally — by getting them to measure their steps, to pay attention to how fast they walked, and to understand how the movement of the stars was related to the change of seasons.“We took the students to the roof of the Science Center and had them identify some major stars,” he said. “They watched the movement over the course of an hour to try and get that motion ingrained.”Huth explained some other primitive navigation technologies to the crowd. Imagine that you’re in the middle of the woods. Your iPhone is out of juice, so there’s no global positioning technology to rely on. The terrain is unfamiliar. There’s not a soul in sight to give you directions. But if no man can help you find your way, a gnomon could. That’s because a gnomon is a stick that casts a shadow made by the sun, which makes it possible to create a working compass.For the course’s final project, Huth had students work in teams. The members of one — the Swiftness Collective — decided to see if they could actually navigate the Harvard campus using the type of sun compass that the Vikings might have had to get around hundreds of years ago. First, the students camped out on the banks of the Charles River on a cold, sunny day to create the instrument, marking off the shadows cast by the gnomon every 15 minutes from sunrise to sunset. The students then used the sun compass to orient themselves and to set the course for several campus landmarks: the Weeks Footbridge, Weld Boathouse, Blackstone Steam Plant, and the Memorial Church. Their bearings were just as good as a magnetic compass, and only a little askew from Google Earth data.When the talk was finished, Rosella Stow of Minneapolis said that she was pleased to know that her daughter, Margaret Nietfeld ’15, could find courses at Harvard that melded the intellectual with the practical.“I thought it was really interesting,” she said. “He’s teaching people what many generations of the past could learn from what was around them, so that his students can say, ‘What’s here to help me get my bearings and go in the right direction?’”The audience was asked to point in the direction they believed was East.last_img read more

Bloomberg named Commencement speaker

first_imgMichael R. Bloomberg, M.B.A. ’66, an entrepreneur and civic leader who built an information technology company into a global news and financial information service and served three terms as mayor of New York City, will be the principal speaker at the Afternoon Exercises of Harvard’s 363rd Commencement.“Mike Bloomberg’s career represents a rare blend of public leadership, private-sector entrepreneurship, and powerful philanthropic engagement,” said Harvard President Drew Faust. “He has led one of the world’s great cities, built one of the nation’s most influential information services, and generously committed his attention and resources to worthy causes in public health, the environment, civic life, the arts, and — not least of all — education. I greatly look forward to welcoming him in May.”Born in Boston and raised in Medford, Mass., Bloomberg received his B.A. from The Johns Hopkins University and his M.B.A. from Harvard Business School, and he has remained closely engaged with Harvard as an alumnus. The renovated Baker Library | Bloomberg Center is named in honor of his late father, William Henry Bloomberg, as is a professorship that was endowed in 1996.He began his career with an entry-level job at Salomon Brothers in 1966, and quickly rose through the ranks to oversee equity trading and sales before overseeing the firm’s information systems. After the firm was acquired in 1981, Bloomberg founded a small startup that used emerging technology to improve the delivery of information to the buyers and sellers of financial securities. Today, Bloomberg L.P. has more than 300,000 subscribers to its financial news and information service and about 13,000 employees worldwide.A believer in the power of philanthropy to improve people’s lives, he established Bloomberg Philanthropies, with areas of focus that include public health, the environment, government innovation, the arts, and education. His commitment to higher education is especially evident in his having given more than $1 billion to his undergraduate alma mater, Johns Hopkins, including particular support for the Johns Hopkins Bloomberg School of Public Health.Elected mayor shortly after the Sept. 11 terrorist attacks destroyed the World Trade Center in 2001, Bloomberg made increasing public safety, as well as improving education and enhancing public health, key areas of focus when he took office. New York voters re-elected him twice. He stepped aside from the mayor’s office on Jan. 1.Earlier this year, United Nations Secretary-General Ban Ki-moon appointed Bloomberg as special envoy for cities and climate change, looking to the former mayor to mobilize municipal leaders to respond to the threats from climate change.“Mike Bloomberg is a prime example of someone who has done well and done good,” said Catherine A. Gellert, president of the Harvard Alumni Association. “I am sure that our alumni will be eager to hear from a member of our ranks whose career has had such a wide impact across the public, private, and nonprofit spheres.”    Bloomberg will speak on May 29 during Commencement Day’s Afternoon Exercises, which serve as the annual meeting of the Harvard Alumni Association. The exercises will take place in the Tercentenary Theatre of Harvard Yard, between Memorial Church and Widener Library.last_img read more

Spacewalkers complete 4 years of power upgrades for station

first_imgCAPE CANAVERAL, Fla. (AP) — A four-year effort to modernize the International Space Station’s power grid is finally complete. A pair of NASA astronauts installed the last battery during a spacewalk Monday, and the unit checked out well. It was the second spacewalk in five days for Mike Hopkins and Victor Glover. Over the weekend, flight controllers in Houston used the station’s big robot arm to replace the last batch of old batteries with a new, more powerful one. Hopkins and Glover quickly put the finishing touches on this newest lithium-ion battery. Their work completes a series of spacewalks that began in 2017.last_img read more

Saint Mary’s to host Meet Me at the Avenue Sunday

first_imgSaint Mary’s will be hosting its annual Meet Me at the Avenue event for students admitted to the Class of 2022 students Sunday.Campus visit coordinator Bekah Stanton said in an email that the event aims to experience Saint Mary’s as a potential student.“It’s intended to give accepted students an opportunity to meet other members of their class, learn more about the College and discover if Saint Mary’s is the place they’re going to call home,” she said.Stanton said they are expecting about 250 students, and 650 guests including family members.The event opens with several talks, for both students and parents together and separate, Stanton said.“The day will begin with remarks by various individuals, including Saint Mary’s College President, Jan Cervelli,” Stanton said. “Following that, the students will branch off to a segment in the residence halls while the parents will remain in the auditorium and hear from current students and their parents on a panel. The entire group will also have the opportunity to hear from a recent alumna about her experience at Saint Mary’s.”Attendees will then have the opportunity to explore campus, she said.“Prospective students and their families will then experience lunch in the dining hall, participate in campus tours and take part in an open house,” Stanton said. “Faculty from each department and club leaders are some of the individuals who will be present during this time. Following this, we offer students and their families the option to go to Mass in the Church of Loretto.”There will also be new events added to the schedule, including showcasing the renovated Angela Athletic & Wellness Complex, she said.“The open house location has changed to the new Angela Athletic & Wellness Complex this year,” Stanton said. “This will allow us to showcase our amazing new space. Because Angela [Athletic & Wellness Complex] is also being dedicated this weekend, we’ve invited students to participate in various activities within the dedication celebration, including workout classes and panel discussions.”She also said admissions is introducing a session for Spanish-speaking families, aimed to help ease their transition into college.“New this year, we will also be hosting a College 101 for ‘Spanish Speaking Families,’” Stanton said. “This will involve a question and answer session with representatives from the office of admission, financial aid and multicultural services, all of whom speak Spanish fluently. It will also include a current parent and current students who will provide examples of what helped them through their first-year transition.”Stanton said Meet Me at the Avenue allows prospective students to get any last-minute questions they may have answered.“Whether their questions pertain to a specific major, about college requirements, or about life on campus, there will be individuals present to answer all,” she said.Stanton said she believes this event is an important opportunity for prospective students to visit the campus.“This is a great way for students to get on campus, meet their potential classmates and discover if they picture themselves at Saint Mary’s,” she said. “We also have a beautiful campus, and I think it’s important for students to visit and see this beauty firsthand. Prospective students are also able to interact with many of our current students during the event, giving them a good indication of the types of great women we have here.”Tags: angela athletic and wellness complex, Class of 2022, Meet Me at the Avenue, Saint Mary’s Admissionslast_img read more

Vietnam likely to scale back coal plant construction program

first_imgVietnam likely to scale back coal plant construction program FacebookTwitterLinkedInEmailPrint分享Bloomberg:Vietnam may scale back a plan to boost coal’s role in its power generation as financial restrictions and local environmental concerns make it more difficult to build plants.The National Steering Committee for Power Development has recommended eliminating about 15 gigawatts of planned new coal plants by 2025 due to slow progress and the unwillingness of some regions to develop them, according to state-controlled news website VietnamPlus. The central government will have final say on the plan.The recommendation underscores how coal’s status as the cheapest and easiest option for developing countries to bring power to their people is being challenged on multiple fronts as richer nations shy away from the fuel. Global banks are refusing to lend, making it more difficult and costly to build plants burning the dirtiest fossil fuel, while costs are tumbling for competing renewable generation.Under the committee’s proposal, coal would provide about 37% of Vietnam’s electricity by 2025 instead of half as previously planned. Renewable power would help fill the gap, increasing to about a quarter of the country’s power from 13% in the existing version. The share for natural gas and major hydropower plants, which comprise most of the remaining capacity, would be left little changed.Vietnam is a flashpoint in the global debate about coal power. About 17 gigawatts of coal power is already under construction with another 29 gigawatts at various pre-construction phases, said Daine Loh, an analyst at Fitch Solutions. It has the fourth-largest pipeline of proposed plants, according to BloombergNEF, many of which have drawn financing in past years from lenders in Japan and other countries.Several banks in Japan, as well as South Korea and Singapore, last year joined lenders from Europe and the U.S. in limiting financing in the fuel because of concerns that climate change would mean the polluting projects would have to be shut before loans could be paid off. The departure of Asian lenders will likely be an inflection point in keeping new plants in places like Indonesia and Vietnam from being financed, BNEF analyst Allen Tom Abraham said in a Feb. 25 report. Private sector companies have proposed building about 20.3 gigawatts of coal plants in Vietnam through 2030, according to BNEF. Less than 8 gigawatts of that has reached financial close, and many of the remaining plants will never get financing, Abraham said.[Mai Ngoc Chau, Dan Murtaugh]More: Vietnam may back off from coal as plants get harder to buildlast_img read more
