Flow of Rutford Ice Stream and comparison with Carlson Inlet, Antarctica

first_imgResults from movement surveys on Rutford Ice Stream are presented with complementary surface-elevation and ice-thickness measurements. Surface velocities of 300 m a−1 occur at least 130 km up-stream of the grounding line and contrast strongly with the neighbouring Carlson Inlet, where a velocity of 7 m a−1 has been measured. This contrast in velocity is not topographically controlled but appears to be due instead to differences in basal conditions, with Carlson Inlet probably being frozen to its bed. Concentration of lateral shear close to the margins and surface expression of subglacial topography both support a view of significant basal shear stresses in the central part of Rutford Ice Stream. The pattern of principal strain-rate trajectories shows a small number of characteristic features which can be compared with results from future modelling of the glacier’s flow.last_img read more

McCutchen wonders what might have been for Pirates

first_imgPittsburgh Pirates All-Star center fielder Andrew McCutchen puts on a Pittsburgh Steelers jersey with his number on it on the sideline before an NFL football game Baltimore Ravens in Pittsburgh on Sunday, Oct 20, 2013. (AP Photo/Gene J. Puskar)by John PerrottoAP Sports WriterPITTSBURGH (AP) — Andrew McCutchen might be the best player on the Pittsburgh Pirates, but he’s not their chief recruiter.The All-Star center fielder doesn’t plan to make any calls to right-hander A.J. Burnett, right fielder Marlon Byrd or any of Pittsburgh’s other free agents in an attempt to talk them into staying.“That’s out of my jurisdiction,” McCutchen said Thursday before hosting a fundraiser for Habitat for Humanity. “Those guys have to make their own decisions. I hope they stay but I also know that other free agents will come here. Pittsburgh isn’t a place for players to come when they (don’t) have anywhere to go anymore.”That’s what happens when a team wins.The Pirates ended their streak of 20 consecutive losing seasons, the longest in the history of the four major professional sports, by going 94-68 this year. They also reached the playoffs for the first time since winning a third straight division title in 1992.Pittsburgh beat the Cincinnati Reds in the NL wild-card game before losing to the St. Louis Cardinals in a division series that went the full five games.McCutchen acknowledged wondering what might have been as he watched the NL champion Cardinals lose to the Boston Red Sox in the World Series.“We took the Cardinals to the limit, gave them everything we had, so it was hard not to think that it could have been us playing the Red Sox,” McCutchen said. “I think we proved in the playoffs that we could play with anyone.“It was a great experience for us and a great experience personally because it was my first time in the playoffs. I tried to savor every minute.”The Pirates’ mission next season will be to prove they were not one-year wonders. Since the day after Pittsburgh clinched its playoff berth in September, general manager Neal Huntington and manager Clint Hurdle have been preaching the importance of sustaining the organization’s success.“We’re not going to rest on what we’ve done,” McCutchen said. “We’re only going to get better as a team and the people upstairs are going to do everything they can to give us the best chance possible.”McCutchen is one of three finalists for the NL MVP award, along with Arizona Diamondbacks first baseman Paul Goldschmidt and Cardinals catcher Yadier Molina. The winner will be announced next Thursday.McCutchen hit .317 with 21 home runs, 84 RBIs and 27 stolen bases in 158 games.“It’ll be interesting because Goldschmidt and Yadi had really good years,” McCutchen said. “There’s nothing more I can do now but wait and see what happens. Obviously, I’d love to win it. I’d definitely find some room in my office for it.”last_img read more

first_imgRafael Nadal’s preparations for the French Open continued apace as he swept past 13th-seeded Jack Sock 6-3, 6-4 Thursday to ease into the Italian Open quarterfinals and extend his winning streak to 17 matches.Fourth-seeded Nadal broke Sock’s serve twice in the second set and served out the match to set up a last-eight meeting with Dominic Thiem, who was beaten by Nadal in the Madrid Open final last week.”I am here to try my best. I know (it) is a tough tournament. I don’t have an easy draw here, a tough one,” Nadal said. “Dominic is the player that is having probably more success now on clay, no? So will be another tough battle tomorrow.”The 30-year-old Nadal has won consecutive clay-court tournaments in Monte Carlo, Barcelona and Madrid. The Spaniard is aiming for an eighth title at the Foro Italico as he prepares for the French Open in less than two weeks.”I think I can play a little bit more aggressive than what I did tonight. I think I have to do it,” Nadal said. “But in general terms I am happy with the way that I played, obviously.”Thiem also beat an American but had to save two match points in a 3-6, 6-3, 7-6 (7) victory over Sam Querrey.Four-time champion Novak Djokovic is also safely through to the quarterfinals after beating Roberto Bautista Agut 6-4, 6-4.

Television replays showed the ball was out.Instead it was Djokovic who broke to take a 5-4 lead and won the match when he had a forehand ruled in.Third-seeded Stan Wawrinka went out of the tournament after losing 7-6 (1), 6-4 to American John Isner, who served up 19 aces in their match.”It’s a situation for me where I’m going out there against the No. 3 player in the world. Maybe I have a little bit less to lose than he does,” Isner said. “I went out there with the belief that, if I played well and executed my game plan, that I could walk off that court with a win. That’s what happened today.”Isner grabbed the only break of the match at 3-3 in the second set before comfortably serving out the match on his first attempt after Wawrinka had saved two match points on his serve.Isner next faces another big server in sixth-seeded Marin Cilic, who dismissed ninth-seeded David Goffin 6-3, 6-4.Home favorite Fabio Fognini, who saw off top-seeded Andy Murray on Tuesday, lost 6-3, 6-3 to Alexander Zverev, who will play fifth-seeded Milos Raonic in the quarterfinals after the Canadian beat Tomas Berdych 6-3, 6-2.In the women’s draw, Venus Williams defeated Johanna Konta 6-1, 3-6, 6-1.Konta had won her previous three meetings against Williams but the American dominated the first set.

The Czech next faces eighth-seeded Elina Svitolina, who recovered to beat Mona Barthel 3-6, 6-0, 6-0.Estonian qualifier Anett Kontaveit, who beat top-ranked Angelique Kerber in the second round, continued her dream debut. Kontaveit beat 16th-seeded Mirjana Lucic-Baroni 6-1, 6-1 to set up a quarterfinal against Madrid Open champion Simona Halep.”I’m just really trying to take it match by match and setting these really small goals,” the 21-year-old Kontaveit said.Sixth-seeded Halep beat Anastasia Pavlyuchenkova 6-1, 4-6, 6-0.Qualifier Daria Gavrilova beat seventh-seeded Svetlana Kuznetsova 2-6, 7-5, 6-4 and Kiki Bertens won 7-6 (3), 6-1 over Russia’s Ekaterina Makarova.last_img read more
