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

Watch moe.’s Al Schnier Play “Deal” On Jerry Garcia’s Travis Bean TB500 Guitar

first_imgToday, guitarist Al Schnier of moe. celebrates a birthday. In honor of Schnier’s birthday, we’re taking a look back at the moe.’s February 7th, 2015 show at Denver’s Ogden Theatre, when Al got the chance to play the late Jerry Garcia‘s Travis Bean TB500 #11 guitar, an axe that Garcia used in 1976.Back in 2015, after he played Garcia’s TB500 #11, Al spoke to Live For Live Music about the experience. In the interview, he explained how the situation came to pass: “Preston Hoffman, our lighting designer, told me maybe a month before, ‘I’ve got something for you that I’m going to have at the Denver show.’ And I said ‘Okay, cool!’ The last time he said that, he showed up with a pair of socks for me. (Laughs) And they’re great socks, he got me these really great wool socks. He found these socks that he loved and he bought them for everybody in the band. It was a really nice gesture. So I’m thinking to myself, ‘Maybe it’s underwear this time.’”He continues, “So a month had gone by, and I had completely forgotten about it and I show up and the Travis Bean is sitting onstage and I’m thinking ‘Oh! That’s what you were talking about!” I knew that he knew the guy, we had talked about it. I didn’t know what the deal was with it. I didn’t know how long it was going to be there. I thought maybe just for the sound check…whatever. Then I found out it was gonna be there the whole weekend and I was going to get to play it as much as I wanted. That was awesome! That guitar happened to be my favorite guitar of Jerry’s.”You can watch video of Al playing the Grateful Dead‘s “Deal” on the TB500 at the Ogden below (via YouTube user Mike Maciunski):You can also listen to audio of the full show below, via user moewu4u: Happy birthday, Al!

High quality apples

first_imgLearning the essentials of marketingIn the Ukraine, Florkowski met with a group of more than 30growers. He taught them the basic principles of postharvesthandling, marketing, sorting, grading and merchandising.”The growers were very receptive and eager to learn,” he said.Last spring, Pennsylvania State University horticulturist RobCrassweller taught the growers about variety selection, dripirrigation, orchard management and pest management. Florkowskiemphasized the link between proper cultural practices andmarketing.”They needed to understand how the grade, appearance, color,maturity and size of the fruit affect their profits,” he said.”Now they have the knowledge to increase their purchasing power,and their incomes are growing.” Expert volunteers sharing knowledgeAn economist with the UGA College of Agricultural andEnvironmental Sciences, Florkowski visited the area as part of aCitizens Network for Foreign Affairs project. Funded by the U.S.Agency for International Development, CNFA organizes volunteerswho provide business and agricultural training to private farmersin parts of the former Soviet Union.”This area of the world is undergoing market reforms,” Florkowskisaid. “The Ukraine is a very young country. The farmers in thisarea produce a large crop of fruits, but they don’t produceenough for even their country’s consumption.”In the off-season, fruits and vegetables are imported from Europeand South America, he said. Immediate results, future possibilitiesFlorkowski said their newfound sorting and grading knowledge willhave immediate impact on the growers’ profit margins.”They’re in the heart of their season and can easily beginsorting and grading,” he said. “This alone should double theirprices.”By chance, Florkowski opened the door to a possible newpartnership for the Ukranian growers.”I went to the local hypermarket (grocery store) and foundshriveled, poor-quality apples,” he said. “They looked likeoversized prunes, and they were expensive, too.”Florkowski contacted the store managers and told them that thelocal growers could easily supply them with fresh, high-qualityapples.”I established the initial contact, and now the managers wouldlike to meet with the growers,” he said. By Sharon OmahenUniversity of GeorgiaIn the height of Georgia’s apple season, it’s easy to find avariety of fresh, high-quality fruit on the produce shelves. Butthis isn’t the case in countries like the Ukraine, wherepoor-quality fruit is sold in the marketplace just miles away fromorchards filled with fresh, high-quality fruit.University of Georgia professor Wojciech Florkowski recentlyreturned from a research outreach trip to the Ukraine, where heshared his marketing skills with apple and pear growers in theKirovohrad Oblast Orchard Association. Real-world experienceThe growers’ benefits from the UGA professor’s visit are obvious.But he believes the trip also benefits the U.S. and fruit growersin Georgia.”I learned new things from my visit to their orchards that I cannow share with growers in Georgia,” he said. “I can now bringthis real-world knowledge back with me and apply it when I talkwith our farmers and our students.”Florkowski said helping new democracies, especially in this areaof the world, directly benefits the United States.”The Ukraine is a strategically important country of U.S.interest,” he said. “It is located on the Black Sea, and the gasand oil supplies there are piped through to Europe. It’simportant to the U.S. for this country to be diplomatic andpeaceful.”Florkowski says CFNA-funded agricultural visits create “highreturns from small investments.””These growers just needed a little knowledge to put them overthe edge,” he said. “You can create quick impact in a relativeshort time, and you gain the satisfaction of helping others.”last_img read more

We are making changes on our wire, effective April 15, to make

first_imgit easier for you to access our stories. The changes relate to: 1. The practice of sending stories in takes (1st take, 2nd take, 3rd take etc). 2. The slugs of our stories. TAKES: Under the new system, we will do away with takes, which are chronological additions to a story. Instead, we will progressively build the story starting with the usual short version of 150 to 200 words. The second story, the slug of which will be prefixed by LD (short for Lead), will be 400 to 500 words and will contain all the material of the first story. The third story (2ND LD) will be 500 to 600 words and so on. This will ensure you get a full story every time, and not truncated parts. There will now be no need to search for different takes and stitch them together for publication. Every subsequent Lead will be a complete and fully publishable story. It will carry an “Editors note” with a brief description of the new material and/or changes in the latest version. SLUGS: All PTI story slugs will be prefixed with two or three letters that will denote the state where they are originating from, or the ministries they relate to. For example: 1. A Tamil Nadu story about water shortage will be TN-WATER SHORTAGE 2. A Chhattisgarh story about a Naxal attack will be CG-NAXAL ATTACK 3. A West Bengal story relating to Mamata Banerjee will be WB-MAMATA-RALLY New Delhi-datelined stories about the central government will carry a three-letter slug that indicates the ministries or departments they are associated with. For example: 1. The external affairs ministry commenting on Pakistan will be slugged MEA-INDIA-PAK 2. The Prime Ministers Office announcing Ajit Dovals trip will be PMO-DOVAL All economic and business stories will carry the preface BIZ. All sports stories will be SPO Cabinet-related stories will be CAB Politics-related stories will be POL A full list of various slug prefaces is attached below: Slugs for the Supreme Court, high court and subordinate court stories will remain the same — SC, HC and COURT. However, this would be prefixed with the state or the Union territory. Some examples of court story slugs: SC-TRIPLE TALAQ, DL-HC-KINDERGARTEN SCHOOLS, MH-HC-DOCTORS STRIKE. For tribunal-related stories, the master slug will be TRIBUNAL like TRIBUNAL-GREEN-POLLUTION. The master slug for states/Union territories will be: 1. Andhra Pradesh AP 2. Arunachal Pradesh AR 3. Assam AS 4. Bihar BH 5. Chhattisgarh CG 6. Goa GA 7. Gujarat GJ 8. Haryana HR 9. Himachal Pradesh HP 10. Jammu and Kashmir JK 11. Jharkhand JH 12. Karnataka KA 13. Kerala KL 14. Madhya Pradesh MP 15.
