Osl Dating of High-Elevation Alluvial Sediments: Mcmurdo Dry
OSL DATING OF HIGH-ELEVATION ALLUVIAL SEDIMENTS: MCMURDO DRY VALLEYS, ANTARCTICA A Thesis Submitted to the Graduate Faculty of the North Dakota State University of Agriculture and Applied Science By Meridith Ann Ramsey In Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE Major Program: Environmental and Conservation Science November 2014 Fargo, North Dakota North Dakota State University Graduate School Title OSL DATING OF HIGH-ELEVATION ALLUVIAL SEDIMENTS: MCMURDO DRY VALLEYS, ANTARCTICA By Meridith Ann Ramsey The Supervisory Committee certifies that this disquisition complies with North Dakota State University’s regulations and meets the accepted standards for the degree of MASTER OF SCIENCE SUPERVISORY COMMITTEE: Kenneth Lepper Chair Adam Lewis Lisa Montplaisir Approved: 04/16/2015 Eakalak Khan Date Department Chair ABSTRACT High-elevation alluvial fans in the McMurdo Dry Valleys are a record of short-term, occasional melting events along the margins of the East Antarctic Ice Sheet. Sediment samples were dated from five fans using Optically Stimulated Luminescence (OSL) dating. OSL dates the time since quartz grains were last exposed to sunlight; all sample preparation takes place in a dark room. Thirteen samples were dated for this thesis, the ages were stratigraphically consistent and ranged from 1.1 ka to 105.9 ka. Clusters of fan activity occurred between 1.1 and 3.1 ka and 8.1 and 11.1 ka. The melting events appear to be linked to insolation, with periods of fan activity occurring usually at times of increased mean annual insolation. The alluvial fans show promise as a possible archive for climate proxies in this region of Antarctica. -

ROVA Saxophone Quartet
FOR IMMEDIATE RELEASE Contact: Glenn Siegel, 413-320-1089 [email protected] Pioneer Valley Jazz Shares presents: ROVA Saxophone Quartet Pioneer Valley Jazz Shares continues its 4th season with a performance by ROVA Saxophone Quartet: Larry Ochs, tenor and sopranino sax; Bruce Ackley, soprano and tenor sax; Jon Raskin, baritone, alto and sopranino sax; Steve Adams, alto and sopranino sax on Tuesday, January 26, 2016 at 7:30pm at 121 Club, Eastworks , 116 Pleasant St, Easthampton, MA 01027. Single tickets ($15) available at www.jazzshares.org and at the door. Rova Saxophone Quartet explores the synthesis of composition and collective improvisation, creating exciting, genre-bending music that challenges and inspires. One of the longest-standing groups in the music, Rova has its roots in post-bop, free jazz, avant-rock, and 20th century new music, and draws inspiration from the visual arts and from the traditional and popular music styles of Africa, Asia, Europe and the United States. In noting Rova’s innovative role in developing the all-saxophone ensemble as “a regular and conceptually wide- ranging unit,” The Penguin Guide to Jazz calls its music “a teeming cosmos of saxophone sounds” created by “deliberately eschewing conventional notions about swing [and] prodding at the boundaries of sound and space…” Likewise Jazz: The Rough Guide notes, “Highly inventive, eclectic and willing to experiment, Rova [is] arguably the most exciting of the saxophone quartets to emerge in the format’s late ’70s boom.” Inspired by a broad spectrum of musical influences – from Charles Ives, Edgard Varese, Olivier Messiaen, Iannis Xenakis and Morton Feldman to The Art Ensemble of Chicago, John Coltrane, Anthony Braxton, Steve Lacy, Cecil Taylor, Sun Ra and Ornette Coleman – Rova began in 1978, writing new material, touring, and recording. -

Henry J. Kaiser (1882-1967) By Ray Atkeson, Photographer This photograph shows Henry J. Kaiser (back seat left) with Governor Charles Sprague (back seat right) and President Franklin D. Roosevelt (front seat right) during a presidential visit to Kaiser’s Portland Shipyards in 1942. Though he rarely visited Oregon, Henry Kaiser was an influential industrialist whose successful ventures in manufacturing and health care significantly impacted the state. Kaiser was born in Sprout Brook, New York, in 1882, and moved to Spokane, Washington, in 1906. In 1914, with his wife Bess Fosburg Kaiser, he founded the Henry J. Kaiser Company, which specialized in road paving. He expanded his industrial empire over the years and, by the time of Franklin D. Roosevelt's administration in the 1930s, it was one of the “Six Companies" that attracted lucrative federal contracts including those for the Boulder (now Hoover), Bonneville, and Grand Coulee dams. During World War II, Kaiser owned three shipyards in Portland and Vancouver, Washington, through his firm Kaiser Industries. At their peak, these shipyards employed more than 130,000 workers in the Portland area. This photograph shows Henry J. Kaiser (back seat left) with Governor Charles Sprague (back seat right) and President Franklin D. Roosevelt (front seat right) during a presidential visit to Kaiser’s Portland Shipyards in 1942. Labor shortages in the region prompted Kaiser to recruit workers from around the country. Since local officials did not want to build housing for these newcomers, many of whom were African American, in 1942 Kaiser purchased and developed land in the Colombia River floodplain at the far northern edge of Portland. -

Kaiser, Garfield, and Permanente
PAPER Kaiser, Garfield, and Permanente Geoffrey C. Nunes, MD enry J. Kaiser developed an extensive and complex industrial empire. During the con- struction of the Grand Coulee Dam in Washington, he began an association with Sid- ney Garfield, MD, that resulted in the prototype of the modern health maintenance organization. Kaiser Permanente, directed by Garfield, survived a confrontation with Horganized medicine in the postwar years and then expanded rapidly in the 1950s and 1960s. At the same time, an internal struggle for control and responsibility of Kaiser Permanente led to a successful reorganization of its health care system. Today, Kaiser Permanente is Henry Kaiser’s most enduring legacy. Arch Surg. 2002;137:1034-1036 Ted O’Connell is the first president of the thus was able to marry Bess.
