Ice-rise stratigraphy reveals changes in surface mass balance over the last millennia in Dronning Maud Land

first_imgWe use ice flow modelling to simulate the englacial stratigraphy of Blåskimen Island, an ice rise in Dronning Maud Land and elucidate the evolution of this data-sparse region. We apply a thermomechanically coupled Elmer/Ice model to a profile along flowlines and through the ice-rise summit, where surface mass balance (SMB), flow velocity and ice stratigraphy were recently measured. We conclude that: (i) the ice rise is presently thickening at a rate of 0.5∼0.6 m ice equivalent per year (mieq a−1), which is twice an earlier estimate using the field data and the input–output method; (ii) present thickening started 20–40 years in the past, before which the ice rise was in a steady state; (iii) SMB contrast between the upwind and downwind slopes was stronger than the present value by ∼23% (or 0.15mieq a−1) prior to ∼1100 years ago. Since then, this contrast has been decreasing overall. We surmise that these SMB changes are likely a result of synoptic-scale atmospheric changes, rather than local atmospheric changes controlled by local ice topography. Our technique effectively assimilates geophysical data, avoiding the complexity of ice flow beneath the ice divide. Thus, it could be applied to other ice rises to elucidate the recent glacial retreat.last_img read more

Messi hits Champions League century in emphatic Barca win over Chelsea

first_imgWith Manchester United dumped out by Sevilla and Tottenham outmanouevred by Juventus, Chelsea’s exit means for all the talk of a Premier League resurgence, Liverpool and Manchester City are its only two representatives in the quarter-finals.Spain have three, after Real saw off the challenge of Paris Saint-Germain.– Fastest Messi goal –Andres Iniesta shook off a hamstring strain to start while Dembele was a surprise inclusion, preferred to Paulinho and rewarded for his excellent display against Malaga.Conte, meanwhile, plumped for Olivier Giroud up front ahead of both Alvaro Morata, who was on the bench, and Eden Hazard, who was granted his wish to play deeper in attacking midfield.Within three minutes, however, Chelse’s plan to frustrate was spoiled. Messi started the move and finished it, with Dembele, Luis Suarez and a deflection off Marcos Alonso, helping him find the space to fire through the legs of Thibaut Courtois for the fastest goal of his career.Chelsea responded well, with Willian and Victor Moses both posing a threat down the right, only for Barcelona to strike again in the 20th minute.Cesc Fabregas failed to secure possession in midfield and Messi was away, skipping past a desperate lunge from Andreas Christensen, before taking the whole stadium by surprise by squaring to the back post.The excellent Dembele took one touch and slammed the ball into the top corner.Alonso and N’Golo Kante both went close before half-time, the latter arguably robbing Fabregas of an easier finish with the Spaniard’s right foot. Alonso then clipped the edge of the post with a bending free-kick just before half-time.After an hour, however, any hopes Chelsea had of a comeback were extinguished. Suarez raced through midfield but looked to have hit a wall on the edge of Chelsea’s box.Messi took over, tearing past the rooted Moses and banging the ball, again through the legs of Courtois, into the net.Antonio Rudiger headed against the bar late on but Chelsea could not even find the scantest of consolations. Messi’s work was done.Share on: WhatsApp Chelsea, in touch after the 1-1 draw at Stamford Bridge, were therefore unfortunate enough to encounter the striker fresh, free and at his frighteningly brilliant best.At the finish, Chelsea coach Antonio Conte left the field with his arm around the forward, perhaps with nothing to add but congratulations.Conte’s team had chances, particularly in the first half, but the sense was once Barcelona were in front they were content to sit back and counter. Barcelona, Spain | AFP | Barcelona hailed Lionel Messi as ‘The King’ and he handed Chelsea the royal punishment by scoring twice to reach 100 Champions League goals and end their quarter-final hopes.After unfurling a banner showing the words ‘God Save The King’ before kick-off, Barca’s fans were celebrating after just 129 seconds at the Camp Nou as Messi found the net before Chelsea had even made a pass.He then teed up Ousmane Dembele to double Barca’s lead in the second leg of the last-16 clash before registering a century of Champions League goals on his 123rd appearance to complete a 3-0 victory, 4-1 on aggregate.Messi becomes only the second player to reach the milestone in Europe’s premier tournament, following Real Madrid’s Cristiano Ronaldo, who has 117 goals in 152 games.By the end, the Argentinian’s scintillating breakaway in the build-up to Dembele’s first Barcelona goal had become little more than a footnote to what was another Messi masterclass.It caps a remarkable five days for the 30-year-old, who sat out Saturday’s La Liga win over Malaga to attend to the birth of his third child.last_img read more

England women’s football team to train in Qatar for first time

first_imgDoha, Qatar | AFP | England’s women football team will hold a winter training camp in World Cup 2022 host Qatar this month, officials in the Gulf and the English Football Association confirmed on Monday.The team will train at Doha’s Aspire Zone from January 14-22, said officials in Qatar, as they continue preparations for the World Cup later this year and ahead of taking part in the SheBelieves Cup, a four-team tournament in the United States in February and March.“The training camp in Qatar is crucial for our SheBelieves Cup preparation and an ideal opportunity for us to work as a group as we begin an important year,” said England coach Phil Neville.It the first time the English women’s team has trained in Qatar, although the men’s side played — and lost — a friendly in Doha against Brazil in November 2009.Twenty eight players will make the journey from the UK to the Gulf, with the squad expected to be announced Tuesday.The women’s World Cup takes place in France in June and July. England’s women’s team is joining a host of other sides — domestic and international — currently training in Qatar.Bayern Munich and PSV Eindhoven are already in Doha, with Qatari-owned French champions Paris Saint-Germain flying out on Sunday (13th).At least seven other club sides will train in Aspire during this month.Among the national teams in Qatar are Sweden and Finland, who will play each other in a friendly on Tuesday.The English Football Association, which failed in its bid to host the 2018 World Cup, has previously been a critic of the decision to host the 2022 tournament in Qatar.However, in February last year, the Qatari and English Football Associations signed a “memorandum of understanding” in Doha to “share resources and expertise, develop knowledge (and) understanding” of football issues.Share on: WhatsApplast_img read more

10 months agoShevchenko: AC Milan now have right men in charge

first_imgAbout the authorCarlos VolcanoShare the loveHave your say Shevchenko: AC Milan now have right men in chargeby Carlos Volcano10 months agoSend to a friendShare the loveAndriy Shevchenko says former AC Milan teammate Rino Gattuso is the right coach for the club.The former Milan striker admits he’s a fan of Gattuso’s style.The Ukraine coach told Gazzetta dello Sport, “Very good, I like this attitude of the club, there are people who have clear ideas, who do not dance in the periods of difficulty: Leonardo and (Paolo) Maldini are working calmly and competently, Leo and Paolo know the reality better than anyone else, and then there is the blocking of the market: if you can only work on loans, getting back to the top is not easy. “I hope that Milan can continue to work serenely for the ascent. Rino’s support is very important because he is working well, he has given the team a sense of belonging. This is the right man for Milan, and I am happy with the confidence that he is collecting from the club.” last_img read more

Tis the season for doorstep stealing Shoppers vent about delivery security

first_imgTodd Bailey is fed up with delivery companies that drop his online purchases at his door.A few years ago, the Grande Prairie, Alta., resident was at the hospital for the birth of his child when a big-screen TV he had ordered was left on his front stoop.Bailey figures the enormous box, a target for would-be thieves, was there nearly 24 hours. The frequent online shopper has been repeatedly frustrated that expensive purchases have been left unattended rather than transported to a safe location like a post office.“It’s not the first time but it still surprises me when you come home and there’s a big package on your doorstep out there for everyone to see,” Bailey says.“I think the assumption is it’s being delivered to a person and not to an address. The assumption is it’s being delivered to go inside the house.”For some shoppers, having a package left at their home — especially if it’s placed in an inconspicuous spot — is preferable to trekking to a faraway depot that’s always busy.But Facebook neighbourhood groups and local news broadcasts are now frequently reporting on thieves caught on home security cameras stealing packages left outside.On Thursday, Bailey tweeted a photo to Purolator of a box left against his door. It was a Christmas gift from his mother for his seven-year-old son.“It’s almost too easy (for a thief),” he says. “It just boggles your mind.”In response to his tweet, a customer service representative for Purolator replied: “Our delivery service requires a signature however if the sender selects the signature-not-required service, and there’s no risk of it being stolen or damaged, we’ll honour it.”There are no easy answers for consumers who are victims of theft.In an email, a Purolator spokeswoman said “the receiver should notify local authorities. They can also file a claim with Purolator.”Meanwhile, Canada Post and UPS Canada both say shoppers should contact the retailer. FedEx Canada did not respond to an interview request but a page on its website invites customers to file a claim if a package is lost.Amazon.ca shoppers are told — if they read the legalese in the site’s conditions of use — that “risk of loss and title for items purchased from Amazon.ca pass to you upon our delivery to the carrier or, if such items must cross an international border, then risk of loss and title pass to you when they clear customs.”Amazon added in a statement that “the vast majority of deliveries make it to customers without issue. In the rare case something occurs, we work with customers directly to make it right.”The Seattle-based company thinks it’s solved the problem with its new Amazon Key product, which allows a customer’s door to be wirelessly unlocked to accomodate a delivery. A camera records the drop-off to protect against anything inappropriate and the door locks as soon as the delivery is complete. The service is not yet available in Canada.Canada Post spokesman Jon Hamilton agrees that package theft is still “a small issue that gets a lot of attention,” but could not provide any figures on how many complaints the organization receives.While he acknowledged it does happen, he notes the volume of parcel deliveries is at an all-time high.“What we have right now with (holiday) online shopping is we’re delivering over one million parcels a day across the country,” says Hamilton, noting the postal service hit that daily marker 60 times this year.He invites shoppers that are afraid of theft to use Canada Post’s FlexDelivery service, which allows online purchases to be directed to a post office for pickup.But some Canada Post locations have been overloaded by packages being stored for online shoppers. On Friday, there were six across the country that were jammed full and unable to accept any new deliveries.“The one part of the process we can’t control if a parcel goes to a post office is when people will pick it up. About 80 per cent of the parcels that are dropped off at a post office get picked up within three days and there’s about 20 per cent that will linger,” Hamilton says.“And at this time of year when more and more parcels are arriving every day with online shopping, that can add up.”He added that one major retailer’s recent sale on the Instant Pot wrecked havoc with Canada Post’s network, given how large the cooking devices are.“(We) were chock-a-block with Instant Pots … so you can imagine how that could eat up a lot of space in a short period of time.”Bruce Cran, president of the Consumers’ Association of Canada, says e-commerce is still in its relative infancy so it’s not surprising that there are inefficiencies in the delivery process.He also believes that on a percentage basis, the number of packages being stolen is small.“Consumers love the convenience and at the moment, I don’t think there’s an immense danger in people looking to take deliveries,” Cran said.“I don’t get the impression at the moment that it’s anywhere near the quantity that would prevent us from utilizing these services. We value being able to order on Thursday night and maybe get it on Friday morning.”last_img read more
