Investigating changes in basal conditions of Variegated Glacier prior to and during its 1982–1983 surge

first_imgThe Variegated Glacier (Alaska) is known to surge periodically after a sufficient amount of cumulative mass balance is reached, but this observation is difficult to link with changes in the basal conditions. Here, using a 10-year dataset, consisting in surface topography and surface velocity observations along a flow line for 25 dates, we have reconstructed the evolution of the basal conditions prior and during the 1982–1983 surge. The model solves the full-Stokes problem along the central flow line using the finite element method. For the 25 dates of the dataset, the basal friction parameter distribution is inferred using the inverse method proposed by Arthern and Gudmundsson (2010). This method is here slightly modified by incorporating a regularisation term in the cost function to avoid short wave length changes in the friction parameter. Our results indicate that dramatic changes in the basal conditions occurred between 1973 to 1983. Prior to the surge, periodical changes can be observed between winter and summer, with a regular increase of the sliding from 1973 to 1982. During the surge, the basal friction decreased dramatically and an area of very low friction moved from the upper part of the glacier to its terminus. Using a more complex friction law, these changes in basal sliding are then interpreted in terms of basal water pressure. It confirms that dramatic changes took place in the subglacial drainage system of Variegated Glacier, moving from a relatively efficient drainage system prior to the surge to an in efficient one during the surge. By reconstructing the water pressure evolution at the base of the glacier it is possible to infer realistic scenarios for the hydrological history leading to the occurrence of a surge.last_img read more


first_imgBy Brad HaireUniversity of GeorgiaCogongrass can completely take over a forested area, smothering out all other vegetation and changing the ecosystem. It’s a widespread problem in several Southern states. But not in Georgia — yet, says a University of Georgia forestry expert.From now until early summer, its fluffy, silvery seed heads will wave like flags marking spots in the forest, along roadways or other places in Georgia where cogongrass has taken a hold, said Dave Moorhead, co-director of the Center for Invasive Species & Ecosystem Health on the UGA Tifton, Ga., campus. “Right now, no other grass in Georgia has that kind of seed head,” he said. “It’s the best time of year to find it and start measures to control it.”Moorhead, along with 22 public and private partners in the Georgia Cogongrass Task Force, has spearheaded state-wide trainings to help UGA Cooperative Extension agents and county road crews identify cogongrass.“County road crews out on equipment are more likely to see infestations, especially this time of year,” Moorhead said.Since arriving as packing material aboard cargo ships landing in Alabama a century ago, the invasive grass has moved throughout that state, Mississippi and Florida, where it covers more than a million acres. But its spread in Georgia has been limited and slow, he said. The likely reason is that cogongrass was planted as livestock forage for several years in the states that now have problems with it, but not in Georgia. And it’s best to keep it that way, he said.The grass can grow any place that isn’t permanently wet. It’s even saltwater tolerant. Once it has a foothold in an area, the grass can be very difficult to kill, he said.“You can’t control it with a single herbicide treatment. You can’t treat once and just walk away,” he said. “It’s an ongoing treatment for many years to eliminate it from an area.”To date, cogongrass has been identified on 220 sites in 28 Georgia counties. The largest site is 10 acres. “But we know there are more sites out there,” Moorhead said.To learn more about the grass and how to identify it, go to the Web site cogongrass.org. If you see a suspect site, contact your local UGA Extension office by calling 1-800-ASK- UGA1.last_img read more

Keeping your team and yourself engaged through the summer!

first_img 27SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,Jim Bouchard “THE SENSEI LEADER is not just another leadership development program. It is a movement.”Our programs support this movement and help us fulfill our vision and mission…                                                                     Summer can too often be an excuse to put things on hold — especially leadership development and training. It’s easy to make excuses:•           People are juggling vacation schedules.•           They’re busy with family activities.•           The nice weather can be a distraction.•           It’s just too damn hot!Any or all of these concerns may be a factor! But there’s a lot you can do during the summer season to keep your team engaged and motivated — and help you grow as a leader.Summer activities provide great opportunities for networking and strengthening the social bonds that make a team more cohesive and productive. Take your team out of the office — take them outdoors! Golf outings, hikes, kayak trips, softball games and barbecues can be strictly social or can be combined with training activities. A change of venue can make meetings more enjoyable.Personal development and professional development are inseparable. For example, taking a rock climbing class or going on a sea kayaking adventure trip can help you develop courage and confidence. When you go back to the office and face a new challenge, your brain now operates with the higher level of courage and confidence you developed on the cliff or on the ocean. These types of activities change your inner wiring — literally change you as a person — and those changes help you become a more courageous and confident leader.The best leaders lead by example. There’s nothing more inspiring than sharing a challenging adventure with your team and allowing them to know you better as a person. Sharing these activities provides opportunities for everyone to develop personally, and deepens the connections and mutual respect that help the team function more effectively on the job.Aspiring and emerging leaders can develop leadership skills and experience by organizing these activities.Recent research points to the benefits of getting outdoors. Even looking at pictures of nature improves productivity and reduces stress and even sick time, but actually getting outdoors produces the best results by far. Combining even light forms of exercise with nature increases benefits exponentially.Encourage people to go on “think walks” and “walking meetings.” Watch productivity, creativity and health soar!I’d be remiss if I didn’t put in a plug for my fellow martial artists. I’m sure you’ve seen those folks doing Tai Chi in the park — what better time than a nice summer evening to give it try? Some organizations offer Tai Chi, yoga and other similar programs outdoors during the summer at lunch hours or designated health breaks.Down time is good too!Sometimes there’s nothing more energizing than enjoying some quality time just sitting near the ocean, lake or pool. Use this time to turn off the noise. Reflect on what’s going on in your life and clarify new plans and goals.The old Masters understood that you can’t clear a jar of muddy water by shaking it. You have to let it sit. The muck settles to the bottom leaving the clear water on top. That’s how your mind works too. You can achieve a much higher plane of thinking when you let the noise and clutter settle and take some time to clear your mind.The iconic motivational speaker Charlie “Tremendous” Jones famously said “You will be the same person in five years as you are today except for the people you meet and the books you read.”What better time to meet people and read books than summer?And now we can “listen to books” too!Subscribe to Audible, Amazon Audio Books or any number of other services. Many that are free. Take your learning on your next summer walk or bike ride or when you’re enjoying that chaise lounge poolside.Don’t just listen to technical books — expand your leadership horizons by listening to biographies and stories about leaders overcoming great challenges. Encourage the people on your team to do the same. Organize an informal “book club” meet-up once where everyone can share what they’ve been learning.Some leaders hit the pause button during the summer. That’s a big mistake.Just don’t worry too much about trying to find time for everyone to do everything. More people take vacation or personal days during the nice weather. Provide just enough activity so everyone can participate in some fashion throughout the summer.Summer is a perfect time to cultivate leadership — at all levels; and to cultivate your personal leadership qualities to even higher levels!
