The response of Petermann Glacier, Greenland, to large calving events, and its future stability in the context of atmospheric and oceanic warming

first_imgThis study assesses the impact of a large 2010 calving event on the current and future stability of Petermann Glacier, Greenland, and ascertains the glacier’s interaction with different components of the climate and ocean system. We use a numerical ice-flow model that captures the major aspects of the glacier’s mass budget, the resistive forces controlling glacier flow, and includesdynamic calving. Satellite observations and model results show that the recent break-off of 25% of thefloating tongue did not result in a significant glacier speed-up due to the low lateral resistance of thisrelatively wide and thin ice tongue. We demonstrate that seasonal speed-up at Petermann Glacier is mainly driven by meltwater lubrication rather than freezeup conditions in the fjord. Results also show that sub-shelf ocean melt may have a profound effect on the future stability of Petermann Glacier, emphasizing the urgent need for more observations, and a better understanding of fjord temperaturevariability and circulation.last_img read more

B’ville girls lacrosse stopped short in state Class A final

first_img“These kids have come such a long way,” said Bees head coach Megan Collins. “My girls never gave up until the final seconds.”Here was the moment where B’ville’s combination of vast skill, tough defense and roster versatility would get put to the ultimate test, but nothing was more important than demonstrating stamina.A day earlier, the Bees had gone to overtime to battle past Bethlehem 15-14, while Northport had a far easier time defeating Pittsford 13-3, and B’ville knew that it would need an all-out effort to tame another group of Tigers, who were also seeking a second state title, having won it before in 2011. “The (Bethlehem) game took a bit of a toll on us,” said Collins. “I could tell that (the players) were tired, and I knew that this was going to be tough.”Still, B’ville got the start it wanted, Jenna Pastore scoring on a free position in the game’s opening minute. But that was the only lead the Bees would enjoy.Northport used three goals in 58 seconds, two of them by Duke-bound Olivia Carner, to move out in front, only to have Hannah Johnson and Emma Gebhardt answer with two goals in eight seconds that made it 3-3.They traded goals twice before the late stages of the half. when Northport struck for goals by Ella Cabrera and Kaylie Mackiewicz, grabbing a 7-5 edge at the break. As it turned out, the Tigers never trailed again.Twice in the second half, Pastore would put in goals that moved the Bees within one, but each time the Tigers answered, including Carner’s fifth goal with 11:57 left.Protecting that slim lead, Northport slowed the pace down, especially in the last 10 minutes. “It’s hard (to come back) when a team is stalling,” said Collins.Even with the Tigers’ slowdown tactics,  B’ville three times forced turnovers, but each time gave the ball back to the Tigers, who were able to finish it from there.In the aftermath, the sadness felt by Bees players and fans was tempered a bit by the youth in its lineup. Star defenders Emme Foote, Maddie Czyz and Ciara Curtis graduate, as does midfielder Sarah Klein and attacker Emma States, but many stars, including Johnson, Gebhardt, Pastore, Katie Pascale, Olivia Muscolino and goalie Jordan Roy, come back for 2020. Share this:FacebookTwitterLinkedInRedditComment on this Story From the time it ascended to the top of the state rankings in mid-April, the Baldwinsville girls lacrosse team knew that such a lofty status meant little until the end.And when that conclusion arrived on Saturday afternoon at SUNY-Cortland, and the Bees were tough and resilient – but Northport, the champions of Long Island, proved a bit better, prevailing 10-8.So the 2000 state championship won by B’ville remains the lone time that its season ended with the ultimate prize, even though this season was a special one from start to finish.

Appiah:Black Stars cannot get complacent

first_imgThough assured of massive home support in the first leg playoff of the World Cup qualifier against Egypt, Ghana coach Kwesi Appiah insists the Black Stars cannot get complacent.The Black Stars, chasing their third consecutive appearance at the finals must navigate past Egypt over two-legs to reach Brazil.Appiah is confident that Ghana can turn their World Cup dream into reality if they stay grounded and show respect to their opponents, who are one of the continent’s best teams. “It’s a big game,” the Black Stars coach told www.ghanafa.org. “It’s a game which is important to all Ghanaians and every member on my team is aware of that.””Egypt are seven-time African champions and trying to reach the World Cup for the first time since 1990. That will give them some added boost going into the game.”Egypt’s achievement, according to Appiah should serve as motivation for his players to get a good result at the Baba Yara Stadium. “Their record in its sense means that we cannot look down on them. We can’t get complacent. We have to prepare well and remain focused,” Appiah said.The Ghana coach believes the Black Stars will be better equipped to deal with the atmosphere in Kumasi, having experienced big game moments like their previous World Cup qualifier against Zambia.”The expectation will always be there whenever the Black Stars have a game.”I can say I was more anxious during the Zambia game. There’s been no panic since the pairing with them[Egypt].”I have respect for them. They are a good side,” concluded the Ghana coach.
