A ground-based radar for measuring vertical strain rates and time-varying basal melt rates in ice sheets and shelves

first_imgThe ApRES (autonomous phase-sensitive radio-echo sounder) instrument is a robust, lightweight and relatively inexpensive radar that has been designed to allow long-term, unattended monitoring of ice-shelf and ice-sheet thinning. We describe the instrument and demonstrate its capabilities and limitations by presenting results from three trial campaigns conducted in different Antarctic settings. Two campaigns were ice sheet-based – Pine Island Glacier and Dome C – and one was conducted on the Ross Ice Shelf. The ice-shelf site demonstrates the ability of the instrument to collect a time series of basal melt rates; the two grounded ice applications show the potential to recover profiles of vertical strain rate and also demonstrate some of the limitations of the present system.last_img

LISCR, Union Douala in Sticky Tie

first_imgLiberia’s 2012 football giant LISCR FC settled to a 3-3 tie with Cameroonian Union Sportive de Douala (USD) in a friendly match on Monday at the Antoinette Tubman Stadium in Monrovia.The pulsating draw is the first time for a Liberian team to draw with a Cameroonian outfit.LISCR’s lanky midfielder Fred Brooks get the opener in the 7th minute through a header.

But a Liberian referee, who begged for anonymity termed Coach Agbor’s assertion as erroneous and argued that the officiating was fair.He said he was taken aback over the coach’s statement, pointing out that they drew with a better side. It may be recalled that in 2013, the Cameroon runner-up winner tossed LISCR FC from the CAF Champions Club tournament on a 3-1 aggregate.Union Sportive de Douala whipped LISCR FC 2-1 in Douala, Cameroon and also 1-0 in Monrovia.LISCR and Union Sportive de Douala’s sticky draw in the friendly followed a convincing 3-1 win over Liberia’s football giants Nimba United by the Cameroonian runner-up champions.Meanwhile, Nimba United is expected to play her return match in two weeks.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)last_img read more

Talent runs in family

first_imgAndrew, 22, has been playing the cello since he was a fifth-grader at Viewpoint School in Calabasas. And at 16, he played Hayden’s “First Cello Concerto” with the New West Symphony. In May 2006, he graduated from the Manhattan School of Music with the Hugo Kortschak Award for Excellence in Chamber Music, and this fall the Escher quartet will begin a three-year residency at the Chamber Music Society of Lincoln Center in New York. “I’m stunned,” Lawrence Janss said about his son’s accomplishments as a cellist. “I’m popping buttons off my shirt every day, I’m so puffed up about him. I’m not musical at all, but I like to think I had some influence on (Andrew’s) venturing into the world of art.” Andrew Janss formed the Escher String Quartet with other students from the Manhattan School of Music, including violinists Adam Barnett-Hart and Wu Jie and violist Pierre Laponte. Although he expects to live in New York for the next decade, he misses California and is looking forward to his performance in Ventura next month. THOUSAND OAKS The Janss family is known in Southern California for developing Westwood, Thousand Oaks and parts of the San Fernando Valley. Now, add art to the family resume. Photographs by Lawrence Janss of Thousand Oaks were used to develop “Yosemite: Journey of Light,” a fusion of his photography and the music of Robert Kyr that was performed by the New West Symphony in Brentwood, Oxnard and Thousand Oaks in April. And Janss’ son, Andrew, is slated to perform Thursday as a cellist with the Escher String Quartet in the Ventura Music Festival. “It’s my first coming back as a professional,” he said. “I don’t get to come back to California nearly as much as I would like. There is a solid-core classical music audience in Ventura County,” he said. “There are people who supported me when I was coming up and there are expectations I don’t want to disappoint.” Andrew’s great-great-grandfather, Peter Janss, was a doctor who came from Denmark to the United States in the 1800s and started the family’s real-estate business. His sons, Edwin and Harold, bought 10,000 acres in the Conejo Valley and developed 3,000 acres in Westwood, donating to the state the land to build UCLA. Edwin Janss Jr. headed the development of Thousand Oaks on the family ranch land that covered much of what is downtown Thousand Oaks today, including The Oaks shopping center and the Janss Marketplace. One of the city’s main streets, Janss Road, is named after the family. Edwin Janss Jr. also built a reputation as an underwater photographer and a collector of works by young artists before they had received widespread public recognition. Lawrence Janss, 57, studied photography with Ansel Adams, whose photographs he also collected, and in 1998 produced his own photographic interpretation of Ferde Grofe’s “Grand Canyon Suite,” which was premiered by the New West Symphony. He recently exhibited his photos of Yosemite in a fusion of still and motion pictures with the music in “Yosemite: Journey of Light.” Lawrence Janss was also instrumental in saving the historic Moorpark Theater on High Street, which he bought in 2001 and renovated before selling it to the city of Moorpark in 2004.
