An updated seabed bathymetry beneath Larsen C Ice Shelf, Antarctic Peninsula

first_imgIn recent decades, rapid ice-shelf disintegration along the Antarctic Peninsula has had a global impact through enhancing outlet glacier flow, and hence sea level rise, and the freshening of Antarctic Bottom Water. Ice shelf thinning due to basal melting results from the circulation of relatively warm water in the underlying ocean cavity. However, the effect of sub-shelf circulation on future ice-shelf stability cannot be predicted accurately with computer simulations if the geometry of the ice-shelf cavity is unknown. To address this deficit for Larsen C Ice Shelf, west Antarctica, we integrate new water-column thickness measurements with existing observations. We present these new data here along with an updated bathymetry grid of the ocean cavity. Key findings include relatively deep seabed to the south-east of the Kenyon Peninsula, along the grounding line and around the key ice shelf pinning point of Bawden Ice Rise. In addition, we can confirm that the cavity’s southern trough stretches from Mobiloil Inlet to the open ocean. These areas of deep seabed will influence ocean circulation and tidal mixing, and will therefore affect the basal-melt distribution. These results will help constrain models of ice-shelf cavity circulation with the aim of improving our understanding of sub-shelf processes and their potential influence on ice shelf stability. The data set comprises all point measurements of seabed depth and a gridded data product, derived using additional measurements of both offshore seabed depth and the thickness of grounded ice. We present all new depth measurements here as well as a compilation of previously published measurements used in the gridding process. The gridded data product is included in the supplementary material.last_img read more

Unlocking doors

first_imgThis is one in a series of profiles showcasing some of Harvard’s stellar graduates.When Dominique Donette tells you that she was born in a prison, she’s not speaking metaphorically. Donette’s mother gave birth to her in a federal penitentiary while serving time for a nonviolent offense. “My mom was a sex worker; my dad was a pimp,” Donette said in an interview. Growing up, she attended more than two dozen schools as she moved around California’s Bay Area and beyond, living alternately with her parents, foster parents, and relatives.Now, Donette is about to graduate from Harvard with a master’s degree in education policy and management. But she’s not pushing a “bootstrap” message, she cautioned. “I don’t want to tell that lie to people. … ‘I made it, you can too.’ So many people are working so, so, so hard who will never have the opportunities I had.”One of those opportunities, in the midst of her chaotic upbringing, was a six-month stint in Hawaii, attending a well-funded private school. “Because of my parents’ lifestyle, there were some moments of privilege,” Donette said. “But then at another time, I went to the lowest-performing school in Sacramento.” She also attended Sacramento High, where she recalls there weren’t enough books to go around, and as many as 50 students crammed into a classroom. Yet Sac High also had a strong performing arts program that attracted some top students from around the city.Witnessing those contrasts gave Donette an acute awareness of the vast inequities in education, and it helped fuel her journey to the Harvard Graduate School of Education (HGSE).From a young age, Donette threw herself into two pursuits that helped her cope with a troubled home life: studying and volunteering. “I was very active in the church and my community,” she said. “The church is where I started understanding how community organizing works.” She earned a Gates Millennium Scholarship to enroll at the University of California, Berkeley, where she double-majored in dance and American studies.The weather determined the course of her next volunteering focus.“[Hurricane] Katrina happened the day before I started undergrad,” Donette said. “So I spent every spring break and summer throughout undergrad organizing, involved in different change-making campaigns in the Gulf South.”Her other watershed college experience was a study abroad semester in Ghana. Of Persian and African-American descent, Donette said that “I had this strong black identity and I thought I had returned ‘home,’ and [Ghanaians] were like, ‘No, you haven’t,’ ” she recalled with a laugh. “Eventually, I realized the power structures there were so different. The people in power are all black; people in ads and TV are all black; the police are all black. Something happens when you see visions of yourself in these positions.”Indeed, Donette literally saw visions of herself on local TV, after she did some video work as a dancer and choreographer for a Ghanaian pop singer. That came about when California’s budget crisis prevented her scholarship check from arriving on time, and she suddenly needed a source of income.Dancing was a more fun way to pay the bills than Donette’s usual jobs, bartending and housecleaning. Although the Gates scholarship took care of her college expenses, Donette had to take out loans for an unrelated reason: to help with her mother’s legal fees. She even started a small cleaning business while in college.After graduation, Donette moved to New Orleans to work for the nonprofit Kids Rethink New Orleans Schools. The organization was formed to involve the city’s children and teenagers in the discussions and planning of school reform, an initiative that was in danger of being driven by well-meaning adults arriving from elsewhere. “We trained young people with the skills to be the leaders,” Donette said. “Even though I was an outsider also, I think I understood the importance of having local people at the forefront of the decision-making.”Following that and a brief period teaching English in Turkey, Donette tried her hand at politics, working for the campaign, ultimately unsuccessful, to elect Harvard alumnus Marshall Tuck, M.B.A. ’00, the superintendent of public instruction in California. “That was probably the most pivotal moment in my professional career,” Donette said. “It showed me a lot of my weaknesses. … It also helped me understand state politics, and how state and federal government policies affect local education. [I realized] I needed a better framework for policy.” And that drove her to apply to HGSE.At Harvard, Donette has gotten the policy framework she sought. “I have so many personal experiences and anecdotes, but having an actual text to refer to, or actual data or research or law or statute — that’s what I came here for.” Even a nitty-gritty course such as “Introduction to Education Finance and Budgeting,” which “made me miserable,” she said with a laugh, “was great information for me. I need to know how to read a report and talk about money.”The past year has brought Donette some wholly unexpected adventures, such as when a conversation on a rafting trip in Vermont led, later, to a much longer trip — to Senegal, to meet with that country’s minister of education.“It’s been a transformative experience, but not in the way I thought it’d be, and that’s OK,” said Donette.What she’s picked up most of all at Harvard is a new boldness and way of thinking that she hopes will help her in a career tackling inequities in education, in whatever form that career will take.In Donette’s metaphor, “There’s this building, and there’s a floor with a feast behind a closed door, and someone has the key.” “And often folks from high-poverty areas or historically disenfranchised, marginalized communities, black and brown, we often don’t know where the building is, what floor the feast is on, or, if we find the floor, we don’t have a key to the door and don’t know who to ask for it.“Being at Harvard has pushed me to think more like the people who know how to navigate the system,” she explained. “Like if I got to the building, I’d say, ‘Oh the building’s closed.’ But I’ve met Harvard colleagues who are like, ‘Nope, there’s food in this building. I’m getting the key, I’m enjoying that feast.’ So I’ve had to learn to think more like that. To not take no for an answer, for myself or my community, and to learn from the people who’ve felt empowered or confident in their lives.”That said, Donette remains committed to partnering respectfully with the disenfranchised, not imposing solutions on them. As she put it, “I will continue to treat people as experts in their own lives. … Recognizing where I came from, who my ancestors are, the sacrifices that have been made for me, by my grandmother, all the families I stayed with, my parents, even though they weren’t able to parent, the people who stepped in when they couldn’t, all my siblings, my community, I really believe I’ve been afforded this incredible opportunity, so the greatest gift I can give back is to use my skills to push for access for them.”last_img read more

The Late Elizabeth Swados’ Runaways Set for Encores! Off-Center

first_img View Comments Runaways, the innovative 1978 musical by the late Elizabeth Swados, will return to New York as part of City Center’s Encores! Off-Center 2016 season. The announcement comes just two days after Swados’ passing; she was 64.Sam Pinkleton will direct the summer production, with Ani Taj as choreographer. Both were students of Swados’ at NYU Tisch. Additional information, including exact dates, will be announced later.“When I came to Encores! Off-Center, Runaways was at the top of my list of shows to present,” said Artistic Direcotr Jeanine Tesori in a statement. “I have always wanted to honor Liz’s work and thank her for the extraordinary contributions she made as a theater artist. She was a woman to look up to and made room for other artists like myself.” She added, “Since we can’t do Runaways with her, we’ll now do it for her.”Much like how Swados assembled a team of creators and performers from actual runaways, Tesori, Pinkleton and Taj cast the new production from an open call to high schoolers in New York.The original production featured 28 teens, who told their personal stories through songs, monologues and spoken word pieces. The revue was nominated for five Tony Awards: one for Best Musical and four for Swados, who directed and choreographed in addition to penning the book and score.last_img read more

Burlington Mayor Kiss fights back, to call special council meeting on BT

first_imgBurlington Telecom,Burlington Mayor Bob Kiss has taken issue with several aspects of the audit of Burlington Telecom. The audit offered a scathing rebuke of the city’s administration and the financials of the ailing municipal cable, voice, Internet company. The mayor said Friday the city was continuing to review the Larkin Report, anticipating a further response this week.The report was initiated by the Vermont Public Service Department in the Fall of 2009 and released December 10, 2010 (STORY). So far, Kiss said the city has identified several gaps and omissions in the report, including but not limited to:· Larkin staff never contacted or interviewed City officials or the City’s consultant Dorman & Fawcett;· Larkin never interviewed the City’s independent auditors, Sullivan, Powers & Co. (’SPC’);· Larkin’s analysis fails to include recent developments with CitiCapital; and· Larkin failed to account for BT’s current financial status and improvements implemented since Dorman & Fawcett took over interim management of BT nearly 4 months agoThe City’s ongoing review of Larkin’s accounting claims about BT also shows that almost every issue cited from the City’s management letters, in section L of the report, had been addressed by the City by the end of FY10, at least six months before Larkin completed its report. In addition, a formal process for monitoring the Certificate of Public Good (’CPG’) was addressed in September 2009 prior to initiation of the Larkin report; however Larkin failed to note this significant development.‘Our review shows that Larkin failed to understand how and when the City addressed issues identified in auditor management letters, causing the report to be misleading,’ said Chief Administrative Officer Jonathan P.A. Leopold.The Larkin Report does not discuss or address in any way recent developments related to the work of Dorman & Fawcett. The City has terminated its lease agreement with CitiCapital and, through Dorman & Fawcett, is in advanced discussions with several interested strategic and financial partners to procure replacement equipment. Dorman & Fawcett assumed interim management of BT in August 2010, implementing several changes, showing revenue levels above last year’s, and reaching a cash flow position well above operational costs. Larkin failed to contact Dorman & Fawcett about these or any other issues.‘The Larkin Report lacks credibility,’ said Mayor Bob Kiss. ‘Larkin praises the Blue Ribbon Committee but fails to observe that the City has been implementing the Committee’s primary recommendations. With the assistance of Dorman & Fawcett, the City has sought to address the CitiCapital lease while improving BT’s cashflow and the efficiency of BT’s operations. BT’s viability is of paramount importance. It is a major mistake to rely on the Larkin report. It is dated, incomplete, and contains numerous omissions.’Mayor Kiss added, ‘This report has been characterized as independent, which is not true. In reality, it was prepared for the Department of Public Service and David O’Brien in the context of an adversarial proceeding.’ Larkin has been involved with the City and Public Service Department in prior proceedings late last year related to a Burlington Electric Department rate increase. Larkin’s analysis in that case was ultimately rejected by the parties in favor of the City’s position.Mayor Kiss said the City will respond in more detail next week, after additional time to review the report. The City will also consider whether to formally respond to the report to the Public Service Board.In related news, Mayor Kiss announced Friday he will call a special City Council meeting on BT sometime in early January.Burlington, VT ‘ December 17, 2010.

Editorial: Wisconsin’s Governor Wants to Waste Taxpayer Money Fighting Clean Energy

first_img FacebookTwitterLinkedInEmailPrint分享From the (Milwaukee) Wisconsin Gazette: There’s a proposed item in Gov. Scott Walker’s budget that would waste $250,000 to have the Public Service Commission study the health effects of wind turbines. His transparent intention is to continue stalling on Wisconsin’s development of this renewable energy source, which is opposed by the real-estate sector and producers of dirty energy, including Koch Industries and Exon Mobil. Those industries have bestowed Walker with beaucoup bucks, and, as he’s proven time and again, he’s not about to let the state do anything counter to their interests on his watch — not even for the best interests of Wisconsinites.If wind energy did indeed present a health hazard for humans, the world would be well aware of it by now. Wind energy is the second fastest-growing source of renewable energy in the world — behind only solar, Wind has contributed to increasing energy independence and job growth throughout Europe and Asia over the past decade. It’s also led to falling energy costs in nations such as Germany, where 31 percent of energy during the first half of last year came from wind, solar and hydro.Neighboring Iowa generated 27.4 of its electricity from wind in 2013. The state continues to expand its wind energy program, with no reports of health problems that we could find.But there’s even stronger evidence that wind energy is harmless, and Walker is well aware of it. Five years ago, 13 Wisconsinites from all sectors were appointed to the state’s Wind Siting Council. The council reviewed over 50 different scientific studies and found no evidence to support the contention of Walker and his shills that wind turbines are hazardous to human health. The only studies used by the council were those that had appeared in peer-reviewed scientific journals. The findings of the Wind Siting Council, presented to the Legislature in October 2014, should have marked the end of the story for wind energy deniers.The $250,000 Walker wants to spend to duplicate a conclusive study on a topic that has long since been settled elsewhere could be used in many other productive ways.  The Wisconsin League of Conservation Voters suggests that the money could go to programs that contribute to conservation, clean energy, or monitoring the pollution and contamination that we know are caused by the forms of energy that Walker favors.The absurdity of Walker throwing away taxpayer money to hold up the production of clean energy due to public health concerns is laughable. Walker has never met a polluter he didn’t like. His environmental policies are extremely hazardous to public safety, including the relaxation of regulations for polluters, construction of the nation’s largest tar sand crude pipeline, which flows under every major waterway in the state, and revamping the permitting process to make it easier for operators of open pit mines to get approval without public input — just for starters.This is not a partisan issue. Renewable energy is essential to keeping Wisconsin in the game, and the hypocrisy Walker shows toward it should offend every citizen who expects our leaders to do what’s best for us over the interests of their benefactors or in the interests of their political aspirations.Of course, the Public Service Commission, which is dominated by Walker appointees, might just come up with findings that conveniently differ from all the scholarly studies on the subject. If that should occur, we hope that Republicans and Democrats alike recognize the sham for what it is.Editorial: Walker wants $250,000 to duplicate wind energy study because he didn’t like the findings Editorial: Wisconsin’s Governor Wants to Waste Taxpayer Money Fighting Clean Energylast_img read more

Historic Step by Leaders of the Americas toward Alternatives to the War on Drugs

first_img The previous day, he had declared himself ready to debate drug use in his country and the southward flow of money and weapons. In Obama’s view, “it is wholly appropriate for us to discuss this issue.” “I’m not somebody who believes that legalization is a path to solving this problem, but I do think that we can constantly ask ourselves, ‘Are there additional steps we can take to be more creative?’” he said. The 6th Summit of the Americas “agreed on the need to analyze the results of the current (anti-drug) policy and explore new approaches, in order to strengthen this fight and in order to be more effective,” the event’s host, Colombian President Juan Manuel Santos, said at the summit’s conclusion. In the Caribbean port of Cartagena on April 14 and 15, the leaders of the Americas took a historic step in deciding to conduct studies on alternatives to the war on drugs promoted by the United States, which has led to tens of thousands of deaths in the region over the last 40 years. U.S. President Barack Obama agreed to engage in dialogue, although he made clear that he is opposed to decriminalizing drugs. By Dialogo April 17, 2012 Santos praised the “honesty” of debate at the summit and said that “no one dared to put the issue of drugs on the table.” He highlighted that the 31 leaders of the Americas in attendance gave a mandate to the Organization of American States (OAS) to begin that process. Nevertheless, he assessed “that the road will be a long one, because it’s necessary to denounce international conventions.” Ignacio Cano, a researcher at the Violence Analysis Laboratory of Rio de Janeiro State University, stated for his part that this is a very significant decision, because “20 years ago, this topic was practically prohibited. Just five years ago, former presidents began to talk about the issue, and today, it’s presidents in office who are bringing it up.” Santos, for his part, said that “all options are open. The OAS is going to have a series of scenarios that need to be studied, that need to be analyzed with experts.” Central America is suffering the onslaughts of the drug cartels, which in response to the war unleashed in Colombia, with U.S. assistance, in 2000 and the one launched in Mexico by President Felipe Calderón five years ago, have found new territory there for routing Colombian and Peruvian cocaine to the United States. In 2011 alone, 20,000 people died as a consequence of violence linked to drug trafficking in the isthmus, which has 40 million inhabitants.last_img read more

SOUTHCOM and Honduran Marines Train Together

first_imgU.S. Marine Captain Juan Díaz, who is in charge of the training program, elaborated: “The mission is to build an institution of Naval training to establish a pipeline for officers, warrant officers, and enlisted Troops. The requirements for the curriculum were approved in Tegucigalpa and based on the equivalent training used by the Military in the U.S.” Honduran Marines and their counterparts with the United States Southern Command (SOUTHCOM) are training together in the most effective methods to fight organized crime groups and protect natural resources – lessons the Honduran Marines will later teach their fellow service members. “The larger objective is to construct a lasting relationship between SOUTHCOM and the Honduran service members they work with daily to build their capacity and establish a partnership based on shared values, challenges, and responsibilities.” Building a lasting relationship In another joint training operation, the U.S. vessel USNS Spearhead arrived at Puerto Castilla on Sept. 2 to participate in five weeks of training with the Honduran Marine Corps First Battalion, Spanish online daily La Información reported. There, they conducted joint training exercises in maritime, ground, and air operation strategies to halt organized crime activities. To help achieve that goal, a team of 10 U.S. Marines under Captain Díaz’s command trained with the Honduran service members from the Special-Purpose Marine Air Ground Task Force-Southern Command. U.S. service members have also created a training plan for the Honduran Navy, which is based on the U.S. Marine Corps’ Basic Officer School and the U.S. Marine Corps’ Infantry School. That process is similar to the one that U.S. Marines incorporated into training with Colombia’s Marine Corps. “FNH [the Spanish acronym for the Honduran Navy] believes it is important that they receive training identical to what U.S. Marines receive: training, techniques, and strategies taught worldwide in response to the changes represented by new threats, primarily drug trafficking,” Captain De Jesús explained. “The [Honduran] service members were selected from the country’s different naval bases and are receiving training on the theory and practice of personal defense, team management, diving, underwater operations, martial arts, and marksmanship.” Cooperation between Honduras and the U.S. extends beyond the Marine training initiative, as SOUTHCOM has participated in several training exercises with the FNH in May and July in Puerto Castilla. There, 80 Honduran Marines trained in night operations, maritime patrols, immersion, combat survival skills, small- and large-caliber weapons management, river operations, saving lives in combat, outboard motors, and ship maneuvers. The training also included a river course focused on piloting a ship to intercept vessels suspected of transporting drugs. By Dialogo October 16, 2015 “The goal of these training courses is to educate and prepare the naval squadrons in combating drug trafficking using new strategies, striking precise blows against organized crime, aiding the population, and protecting marine resources,” said Navy Captain Juan Antonio De Jesús Rivera, commanding officer of the Trujillo Colón Base in Puerto Castilla, in an interview with Diálogo. “The support provided to us by the United States allows us to have qualified personnel with broad experience who can transmit this learning to our soldiers and maintain control over Honduras’ coasts and maritime borders,” Captain De Jesús said.last_img read more

N Forest 2 – 1 Coventry

first_imgIt was the defender’s first goal in more than a year, since he netted in a 3-0 win over Kilmarnock for Aberdeen, but his finish was impressive.Forest ‘keeper Brice Samba had to make an adept save to keep out O’Hare’s skimming shot, but Forest were deserving of their half-time lead.Maxime Biamou was unlucky not to draw Coventry level early in the second half, when he saw his driven shot bounce back off the foot of the post.An injury to Matt Godden gave Tyler Walker the chance to impress against the club where he came through the academy ranks.But it was O’Hare who was on hand to head Coventry level in the 57th minute as he attacked a cross from Sam McCallum to flick home.Forest almost restored their lead but saw Marosi hold a Taylor header confidently.O’Hare also flashed another decent effort wide and Biamou should have put the visitors in front, but planted a great headed chance straight at Samba.Samba pulled off an outstanding save to deny O’Hare as Coventry pushed hard for a second goal.The Forest ‘keeper also had to beat Walker in a race to a through ball to deny him a chance.Substitute Sammy Ameobi picked out Lolley with a cross, but he could not get enough on his header.Coventry had looked the more likely to snatch the win – right up until the moment Taylor netted from the penalty spot with the final kick of the game.What the managers said…Nottingham Forest’s Chris Hughton: “It has been a difficult time for us with regard to getting goals and sometimes you want a break to go your way. I think we deserved something from the game. Whether we deserved a win or not is something different. But we will take it.“It felt as though, if any side was going to go on and win the game, it would have been Coventry. But just when we thought it was going to end in a draw, we managed to get a goal with the last kick. I thought we were good in the first half but my biggest disappointment was that we did not make the most of the possession we had. We did not have enough shots on goal, we did not create enough opportunities or good crosses. Our build-up play was good.“But we were up against a very well drilled Coventry side who have been together for some time. It was still a good feeling to get that win. Now we just need to take that feeling into the next game, against Wycombe.”Coventry’s Mark Robins: “We would have been disappointed with a point. I thought we were much better in the second half. We hit the post and had numerous chances to finish the game off. Then we shot ourselves in the foot by giving the penalty away, at a point when we had no time to come back.“If you touch Lyle Taylor he will go down, inside or outside the box. You cannot give him the opportunity to do that. McFadzean is saying that he did not touch him but there was clearly a coming together and as soon as he felt contact he was going to go down, which gave the referee a decision to make.“Then he picks himself up and sticks the ball in the back of the net. We have had bad luck but, having said that, we could have made it easier for ourselves by making more of the chances we created. On the upside we have played really well. But to come away with nothing is a real blow.” But then Kyle McFadzean clipped Taylor’s heels in injury time to give the striker the chance to hand the Reds three points from the penalty spot – an opportunity he took with great calmness.Forest almost took the lead in the 12th minute, when Marko Marosi made hard work of what should have been a straightforward save from a driven shot from Anthony Knockaert, with the ‘keeper relieved to see it bounce wide.From the resulting corner, McKenna planted a header narrowly the wrong side of the post.- Advertisement –  Image:Lyle Taylor scored a late winner from the penalty spot for Nottingham Forest Gustavo Hamer conjured Coventry’s first attempt on goal in the 27th minute, but his 22-yard effort was always rising well over the bar.Joe Lolley came close with a header that was deflected wide at the other end.Forest went ahead in the 30th minute following some penalty box pinball that saw both Luke Freeman and Samba Sow have shots blocked, with the latter’s effort deflected perfectly into the path of McKenna, for him to sweep a low shot into the back of the net.- Advertisement – Lyle Taylor’s penalty six minutes into added time helped Nottingham Forest claim a 2-1 victory over Coventry and hand Chris Hughton his first home win as manager.Forest looked to be on course for their fourth 1-1 draw of Hughton’s six-match tenure, after Callum O’Hare’s 57th-minute header had cancelled out a first-half goal from Scott McKenna at the City Ground. – Advertisement – – Advertisement –last_img read more
