Within the Scotia Sea, the axis of the Antarctic Circumpolar Current (ACC) is geographically confined, and sediments therefore contain a record of palaeo-flow speed uncomplicated by ACC axis migration. We outline Holocene and Last Glacial Maximum (LGM) current-controlled sedimentation using data from 3.5-kHz profiles, cores and current meter moorings. Geophysical surveys show areas of erosion and deposition controlled by Neogene basement topography. Deposition occurs in mounded sediment drifts or flatter areas, where 500–1000 m of sediment overlies acoustic basement. 3.5-kHz profiles show parallel, continuous sub-bottom reflectors with highest sedimentation rates in the centre of the drifts, and reflectors converging towards marginal zones of non-deposition. Locally, on the flanks of continental blocks (e.g. South Georgia), downslope processes are dominant. The absence of mudwaves on the sediment drifts may result from the unsteadiness of ACC flow. A core transect from the ACC axis south to the boundary with the Weddell Gyre shows a southward decrease in biogenic content, controlled by the Polar Front and the spring sea-ice edge. Both these features lay farther north at LGM. The cores have been dated by relative abundance of the radiolarian Cycladophora davisiana, and by changes in the biogenic Ba content, a palaeoproductivity indicator. Sedimentation rates range from 3 to 17 cm/ka. The grain size of Holocene sediments shows a coarsening trend from south to north, consistent with strongest bottom-current flow near the ACC axis, though interpretation is complicated by the presence of biogenic grains. Year-long current meter records indicate mean speeds from 7 cm/s in the south to 12 cm/s in the north, with benthic storm frequency increasing northwards. LGM sediments are predominantly terrigenous and show a clearer northward-coarsening trend, with well-sorted silts in the northern Scotia Sea. Assuming a constant terrigenous source, this implies stronger ACC flow at the LGM, contrasting with weaker Weddell Gyre flow deduced from earlier work.
Surface crevasses covered by snow bridges can be mapped remotely on ice sheets and glaciers using active microwave synthetic aperture radar. They are highlighted against the surrounding snow due to increased scattering from the side-walls and base of snow bridges and usually appear as linear features. The contrast between crevasses and crevasse-free regions depends on the design of the sensor, the image acquisition parameters and the properties of the snow. Here we quantify how crevassed regions are represented at X-band for different polarizations, look directions and incidence angles, and discuss whether additional information about their physical properties can be gained from their radar signature. Snow bridge thicknesses and crevasse widths are measured on the ground in the McMurdo Shear Zone and Brunt Ice Shelf by ground-penetrating radar and excavation. TerraSAR-X is shown to reliably distinguish crevasse location, balancing penetration into the snow and horizontal resolution. We provide recommendations for radar imaging parameters that optimize the identification of individual crevasses and crevassed regions.
FacebookTwitterLinkedInEmailJohn McCoy/Getty Images(LOS ANGELES) — Los Angeles Lakers star LeBron James shared a heartfelt tribute to his “brother” and former Olympic teammate Kobe Bryant on Monday, promising to carry on the NBA superstar’s legacy in the wake of his untimely death.In his first comments on the tragedy, James said he had just spoken to Bryant on Sunday — after passing the basketball legend on the all-time scoring list in Philadelphia Saturday night.“I’m Not Ready but here I go. Man I sitting here trying to write something for this post but every time I try I begin crying again just thinking about you, niece Gigi and the friendship/bond/brotherhood we had,” James wrote on Instagram. “I literally just heard your voice Sunday morning before I left Philly to head back to LA. Didn’t think for one bit in a million years that would be the last conversation we’d have.”Bryant was one of nine people on a private helicopter that went down in Calabasas, California, on Sunday, killing everyone on board. He was 41 years old. Bryant’s 13-year-old daughter, Gianna, was also killed in the crash.James, who passed Bryant for third place on the NBA’s all-time scoring on Saturday, said he was “heartbroken and devastated” but vowed to carry on the superstar’s legacy.“Man I love you big bro. My heart goes to Vanessa and the kids. I promise you I’ll continue your legacy man! You mean so much to us all here especially #LakerNation,” he wrote. “Please give me the strength from the heavens above and watch over me! I got US here! There’s so much more I want to say but just can’t right now because I can’t get through it! Until we meet again my brother!!”James shared the post to his nearly 60 million Instagram followers late Monday night. It acquired about four million likes in less than an hour.Bryant was not a frequent Instagram poster, but his last post before his death featured an image of he and LeBron smiling and embracing each other on the court.“On to #2 @kingjames! Keep growing the game and charting the path for the next,” Bryant wrote in the caption Saturday, referring to his successor as the leader of the Lakers.Copyright © 2020, ABC Audio.

After more than a decade at the helm of the Harvard Art Museums, Thomas W. Lentz, the Elizabeth and John Moors Cabot Director, will step down on July 1. Lentz spearheaded the renovation and expansion of the museums, a multiyear project that united the Fogg, Busch-Reisinger, and Arthur M. Sackler Museums under one shining glass roof designed by the award-winning Italian architect Renzo Piano. Lentz spoke to the Gazette about his tenure, his work with the museums, and his future plans.GAZETTE: Can you give us a snapshot of your last 10 years here?LENTZ: The last 10 years have been exhilarating but also something of a grind. This was a long, complex project, and I feel very fortunate that I worked with a group of people who were dedicated, who understood what was at stake, who understood the long-term goals and mission of this great institution, and most importantly who were willing to roll up their shirtsleeves and go to work. When I look back on my decade-plus here at Harvard, I will probably remember the people I worked with more than anything.GAZETTE: What was your biggest hurdle in working on the new Harvard Art Museums?LENTZ: Probably the biggest hurdle with this project was getting people to understand and accept the necessity of change. We wanted to build a museum that could be useful for 21st-century users and used in creative, imaginative ways. Everybody loves the notion of change in the abstract, but change always seems to be something that’s happening somewhere else. So for us, the reality of change was complicated. As with everything in this museum, it was a collaborative process. We talked and debated and argued things ad infinitum, but those conversations and that understanding for the necessity of change is what allowed us to build this new kind of art museum.GAZETTE: What do you think when you see people streaming through the front door?LENTZ: I hope that when people walk in they immediately think of the old museum and recognize elements and experiences of that old museum, but at the same time they also recognize this is different. It’s more transparent. It’s more accessible. I actually have begun to view it as a kind of giant, transparent classroom, and that’s one thing that our architect, Renzo Piano, brought us. It’s now a much more open and light-filled space, and it also makes visible what used to be hidden away here. I can remember early on Renzo saying, “You have great collections, you do important things: Why is it hidden away?” We didn’t want this to come across as a static treasure house or a kind of closed academic bunker. We didn’t want people feeling they needed to have an advanced degree to walk through these spaces. We wanted it to be more open, accessible, dynamic, and clearly connected to what happens here at Harvard in terms of not just the curricular or cognitive life of the University, but also the social life of the University. Walking through the courtyard, it’s now clear that it really is a new kind of public space on the Harvard campus, and it’s a very beautiful space, at that.GAZETTE: What do you see for the future of the Harvard Art Museums?LENTZ: We have a new museum that will train future leaders in art history, conservation, and conservation science, helping form new curators and new art historians. This is a place where close looking and thinking about works of art will always be enshrined; it’s always at the core of our mission. This is a place where new ideas about works of art and new ideas about museums will be hatched. We have three museums with collections of world importance. We have a talented staff here. This is the birthplace of conservation and conservation science in the United States. And this is a place that is supposed to push the ball down the field. It’s supposed to advance knowledge and thinking about museums and works of art and the role they can play in advanced education. So, at the end of the day, my hope is that the Harvard Art Museums will be much more tightly woven into the fabric of what a Harvard education means.GAZETTE: What’s next for you?LENTZ: I’ve been here for almost 12 years and I think this is a natural time to step down. I am originally from out West. And I can say it now: I don’t like cold weather. So I am probably going to head West somewhere. What I want to do is take a deep breath for a while.
Erin McCauliffe Students protest outside of DeBartolo Hall last November in response to the 2016 presidential election, in which President Donald Trump emerged victorious. Since then, student groups have continued to unite in an effort to defend rights and liberties they consider the current presidential administration to be threatening.“It’s amazing, to some extent, how engaged angry people still seem to be,” professor of political science Geoffrey Layman said. “Typically what happens is in the years in between presidential elections, especially in the year right after one, is people disengage, and they pay attention to sports, family and church — stuff besides politics. But I think the level of anger and political engagement that’s around the country right now is remarkable.”While the country works toward healing its ideological divide, Notre Dame’s campus is doing the same.Junior Christian McGrew, president of BridgeND, said there is still an underlying tension on Notre Dame’s campus a year later due to a lack of communication between both sides of the ideological divide.“People are walking on eggshells,” he said. “People are tense and don’t know how to talk about stuff because a lot of people still are in shock. So we need a forum and a way to be able to talk about these very difficult issues while not ignoring an opinion of a large section of America.”Despite this tension, the feelings of panic some students felt after the election have largely dissipated. Junior Jeffrey Murphy, treasurer of the College Republicans, said while he doesn’t think students’ opinions of Trump have changed, he does sense less fear from those who disapprove of Trump and his policies.“I think most people that hate him still hate him; I think most people that love him still love him,” Murphy said. “I think something that at least I feel like is different is … I think there’s less of an apocalyptic feeling in terms of campus energy. Obviously I would say lives have changed a ton in this presidency, but the way students are talking about it, I don’t think [it’s] as much of a doomsday event.”Senior Emily Garrett, who wrote an open letter in response to the University administration’s initial decision to roll back contraception coverage through its health insurance providers, said she believes students have channeled any initial fear into action.“I feel like the mood on campus back then was definitely a little bit of panic mixed with uncertainty, at least for the more liberal students,” she said. “ … We’ve kind of grown out of panic. We’re starting to respond more effectively. We’re kind of organizing more effectively than we were in the beginning. So it’s more of just an organized front against all these political attacks than the original kind of despair and fear that we felt right at the turn of the election.”Junior Gargi Purohit, a beneficiary of the Deferred Action for Childhood Arrivals (DACA) and president of the Student Coalition for Immigration Advocacy (SCIA), said she has personally seen anger on campus become “fuel” for action.“Right now, there’s just a lot of anger, and I think anger is good because anger fuels people,” she said. “Anger fuels people to really demand what they need. So right now, I just see a lot of justified anger from communities, and they’re using their anger to fuel them for these massive movements.”For some students, such as junior Sabrina Barthelmes, being a student at Notre Dame has changed their political alignment. Barthelmes said she grew up in a very conservative family, but after becoming more engaged with social issues at Notre Dame, she began to rethink her priorities.“Coming here, I realized I care a lot about the social issues, and I lean much more liberal for social issues,” she said. “I feel like now I’m actually getting the reverse, where I don’t really talk about the fiscal issues. To be honest, I know what Republicans think, I know what Democrats think, but I don’t know where I lean on that because I don’t feel knowledgeable enough to actually give an opinion.”Whether due to a fundamental lack of communication or fear of rebuke, however, Garrett said students remain “uncomfortable” speaking openly about politics, particularly in a classroom setting.“I think since the election, we’ve kind of marked out in our own social circles who we know would be in support of our own views and who we know is opposed to them,” she said. “ … I’m not necessarily afraid I’m going to incite a huge argument, but I’m also not comfortable touting my liberal views on the quad or anything — not that I think anyone would want to shout their political stance in the middle of a group.”Sophomore Jessica D’Souza said she believes the “exhaustion” among students that comes as a result of such a politically charged climate has caused people to want to step back from politics altogether.“I think that there is an exhaustion, but not in this active ‘I can’t do this anymore’ — but in the ‘I don’t care, I’m apathetic now’ [way],” she said. “And I think that’s easy for a lot of Notre Dame students because we go to Notre Dame. We do exist in this bubble. And the overwhelming majority of people do come from good backgrounds, and their day-to-day lives are not drastically changed by a lot of Trump’s policies.”Murphy said he wishes more students would challenge each other’s beliefs and debate openly about politics. While some students felt nervous speaking about their conservative stances immediately following the election, he said, the time others have taken to listen to their arguments has contributed to some initial reconciliation between students on opposite ends of the political spectrum.“I wish there wasn’t so much intellectual unanimity,” he said. “And I think a lot of conservative students feel very, very afraid of being openly conservative in the classroom. … [But] I think there’s less ill-placed [bad] feelings between conservatives and liberals on campus. I think people have realized that it wasn’t hate-fueled, it was a genuine difference in intellectuality or policy positions.”On the other end of the political spectrum, Purohit said she has gained a sense of empowerment from being open about her political views and her status as an undocumented immigrant.“I think one of the benefits of being so outspoken about it is that even if people on this campus that see you day-to-day or recognize your face don’t agree with this movement, they’re not going to come up to you and share it,” Purohit said. “It’s really hard to go up and criticize and say you don’t believe that undocumented immigrants should be in a country when you’re speaking to one.”On the other hand, due to misconceptions surrounding the Republican party as a whole, D’Souza said she felt pressure to distance herself from those of President Trump’s views that she feels conflict with her identity as a Republican in order to be accepted on campus following the election.“My fear was, how much harder am I going to have to fight to defend my beliefs now that someone that I think doesn’t embody them or fight for them is the person that is the representative of this party?” D’Souza said. “Because I don’t think that misogyny is a platform of the Republican party. I don’t think that bigotry has any place in it. … I don’t think that his rhetoric reflects what I believe.”While Purohit said she is “debating on whether [she needs] to listen to the other side,” other liberal-leaning students such as Garrett are more willing to listen to and debate with students with different political beliefs. Garrett said she feels being able to do so is a vital aspect of a college campus.“I don’t think it should be a taboo subject, because how are we ever going to learn from each other or create a common ground for other initiatives?” she said. “None of my classes have ever really been shy about addressing politics, so I’ve never developed that fear of academic discussion.”This intelligent debate, McGrew said, is the first step toward bridging the remaining ideological divides on Notre Dame’s campus and beyond.“There’s a wide and cognitive dissonance in American politics,” he said. “And if we’re ever going to begin to make progress, we need to first understand the other side. I think that starts with talking to people and asking questions and being curious.”Tags: 2016 Election, BridgeND, DACA, Democratic Party, Donald Trump, political climate, Politics, Republican Party Editor’s note: This is the first story in a three-part series addressing various political issues and their impact at Notre Dame one year after the 2016 election. Today’s story focuses on the current political climate and ideological divides on campus.In the weeks following the 2016 election, in which President Donald Trump beat Hillary Clinton, many Americans took to the streets to express their anger or jubilation. Some marched with signs urging others to fight against the newly-elected administration, while others proudly displayed “Make America Great Again” paraphernalia.Just over a year after Trump’s election, the country appears to be as politically charged as ever.

ASUNCIÓN, Paraguay – The Comando Vermelho (Red Command) and Primer Comando Capital (First Capital Command or PCC), two of the biggest crime organizations operating in Brazil, have become the primary targets of Paraguay’s counter-narcotics forces. “The men in these two organizations come to Paraguay to put together the shipments of marijuana, the [drug] sales and other illegal activities,” said Miguel Chaparro, who heads Paraguay’s Anti-drug Secretariat (SENAD). Chaparro said Paraguay is targeting these crime syndicates because “80% of the marijuana being grown in Paraguay ends up in Brazil, according to statistics.” Chaparro said members of the Comando Vermelho, which is based in Rio de Janeiro, Brazil, and the PCC, which has its roots in São Paulo, Brazil, have established a presence in the Paraguayan cities of Pedro Juan Caballero (Amambay Department), Saltos del Guairá (Canindeyú Department) and Ciudad del Este (Alto Parná Department). What do the Paraguayan cities have in common? They are all on the border with Brazil. “The men come here to assemble several tons of marijuana, which they then send to Brazil,” Chaparro said. “These guys have been doing away with all the small drug producers and dealers in Paraguay, using mafia methods.” SENAD scored a victory on April 7, when agents arrested five Brazilian citizens with alleged ties to the Comando Vermelho during a raid in the municipality of Puente Kyhá in the department of Canindeyú. Two shotguns, a rifle, a machine gun, four bulletproof vests and several 3.3-pound bricks of marijuana ( 3.3 lbs. each) were confiscated from the Brazilians, who were placed in the custody of the Paraguayan district attorney for their alleged involvement in drug trafficking. “By capturing these members of Comando Vermelho, we’ve shown there is a feud with other criminal groups, all trying to control [drug traffic in] that area,” Chaparro said. Chaparro said the departments of Amambay and Canindeyú have the biggest concentrations of marijuana farms. But that may change. SENAD and Brazil’s Federal Police have partnered for operation “New Alliance,” in which agents work together to eradicate illegal crops. On March 23, forces destroyed 250 acres of marijuana planted on an area known as “Sarambí Hill.” “This is equivalent to removing about 312 tons of marijuana from the drug market,” according to a SENAD report. Security forces destroyed 25 camps containing more than 130,000 pounds of marijuana combined. “This means a loss of more than US$4 million” for the narco-traffickers, according to SENAD’s report, which stated Paraguayan marijuana sells for US$1,000 a kilogram (2.2 pounds) in Argentina, Brazil, Uruguay, and Chile. “The SENAD wants to chip away at the drug-traffickers’ finances, destroying marijuana plantations right at harvest time, when they’ve already invested a lot [of money] in the crop, and have already paid the growers and bought equipment for the job,” SENAD said in a statement. In 2010, the SENAD eradicated a total of 2,500 acres of marijuana plantations, containing about 6.6 million pounds of the narcotic. This year, the Ministry of the Interior, through the Counter-narcotics Division of the National Police, implemented operation “Ko’e Pyahu” (New Dawn, in Guaraní). The goal is to destroy narcotics being grown and produced in departments along the Paraguay-Brazil border. So far, the initiative has led to the eradication of 800 tons of marijuana, Interior Minister Rafael Filizzola said. “The estimated value at the production site is about US$10million, and for the regional markets it is US$200 million, which means we greatly hurt organized crime,” Filizzola said during a media conference in February. “With regard to this operation (Ko’e Pyahu), we should establish that there was a prior gathering of intelligence, not only in the departments that were affected but in all departments around the country. For this action we’ve taken as a point of reference those departments that are known for having the largest production of marijuana.” Meantime, Rubén Rosas Florentín, chief commissioner of the San Pedro Police Department, said those growing marijuana often are field laborers who are being exploited by narco-traffickers. “Those growing the marijuana gain the least (economic) benefit because they’re peasants who are being used by middlemen and financial backers,” Rosas told Radio Cardinal. “With these operations [now being conducted], we’re trying to discourage the illegal production of these crops and we’re hoping to convince producers that the best thing to do is to start planting legal crops [instead].” By Dialogo April 15, 2011
2SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr Reps. Andy Barr (R-Ky.) and Ruben Hinojosa (D-Texas) have reintroduced the Helping Expand Lending Practices in Rural Communities Act, a CUNA-supported bill that would grant credit unions and other lenders greater input into rural-area designations.“Having an area designated as ‘rural’ can affect the types of products credit unions can offer members in that area, and CUNA supports any opportunity for credit unions to provide input to the process,” said CUNA Chief Advocacy Officer Ryan Donovan.For instance, credit unions operating in “rural” areas may be exempt for some regulatory burdens, such as an escrow requirements under the Truth in Lending Act that requires certain lenders to create an escrow account for at least five years for higher-priced mortgage loans. They may also be exempt from standards under the Ability-to-Repay/Qualified Mortgage (QM) rules that disqualify mortgage loans with balloon payments from meeting the QM standard.Being exempt from such requirements, CUNA maintains, can beneficially affect the types of products a credit union can offer their members in what can be underserved areas. continue reading »
5SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr In my November Good Governance column, I talked about the importance of having a process in place to identify potential board members, introduce them to the credit union and, eventually, ask them to run for the board. Once directors are elected, you’ll need to build a robust, comprehensive onboarding program that includes such elements as:Public announcement of the election. Kick off your orientation program (and a welcome to the board) with a public announcement of your new colleague’s election. Use this opportunity to get to know your new director and for him or her to know the credit union more closely.Hold both formal and informal board orientations for the board and staff. This is the easy part. Schedule formal briefings with both the board and staff for your new director. From our experience, this is where most credit union orientation programs start … and, sadly, where they also stop. continue reading »
