  • Geochemical Evidence for the Origin of Mirabilite Deposits Near Hobbs Glacier, Victoria Land, Antarctica
    Mineral. Soc. Amer. Spec. Pap. 3, 261-272 (1970). GEOCHEMICAL EVIDENCE FOR THE ORIGIN OF MIRABILITE DEPOSITS NEAR HOBBS GLACIER, VICTORIA LAND, ANTARCTICA C. J. BOWSER, Department of Geology and Geophysics, University of Wisconsin, Madison, Wisconsin 53706 T. A. RAFTER, Department of Scientific and Industrial Research, Institute of Nuclear Studies, Lower Hutt, New Zealand R. F. BLACK, Department of Geology and Geophysics, University of Wisconsin, Madison, Wisconsin 53706 ABSTRACT Numerous masses of bedded and concentrated interstitial mirabilite (Na,SO.·lOH,O) occur in stagnant glacial ice and within and on top of ice-cored moraine near the terminus of Hobbs Glacier on the west coast of McMurdo Sound. Some are tabular bodies up to 50 m long and 4 m thick. They are thought to be deposits formed by freeze concentration and evaporation in supraglacial and periglacial meltwater ponds. Some deposits have been included within ice and de- formed during glacial movement. Structural features within the ice and lithology of the morainal debris indicate the moraine is a remanent mass left during retreat of the formerly extended Koettlitz Glacier presently south of the Hobbs Glacier region. Compositionally the salt masses are predominantly sodium sulfate, although K, Ca, Mg, Cl, and HC0 are also 3 present, usually in amounts totalling less than five percent of the total salts. The mirabilite content of analyzed samples constitutes from 10to nearly 100percent of the total mass: the remainder is mostly ice. Isotopically the 8D and 8018composition of water of crystallization of entrapped glacial ice falls on Craig's (1961) line 18 for meteoric water (80 range -6.8°/00 to -37.9°/00' 8D-58.5°/00 to -30JD/00, relative to S.M.O.W.).

  • Antarctic Bdelloid Rotifers: Diversity, Endemism and Evolution
    1 Antarctic bdelloid rotifers: diversity, endemism and evolution 2 3 Introduction 4 5 Antarctica’s ecosystems are characterized by the challenges of extreme environmental 6 stresses, including low temperatures, desiccation and high levels of solar radiation, all of 7 which have led to the evolution and expression of well-developed stress tolerance features in 8 the native terrestrial biota (Convey, 1996; Peck et al., 2006). The availability of liquid water, 9 and its predictability, is considered to be the most important driver of biological and 10 biodiversity processes in the terrestrial environments of Antarctica (Block et al., 2009; 11 Convey et al., 2014). Antarctica’s extreme conditions and isolation combined with the over- 12 running of many, but importantly not all, terrestrial and freshwater habitats by ice during 13 glacial cycles, underlie the low overall levels of diversity that characterize the contemporary 14 faunal, floral and microbial communities of the continent (Convey, 2013). Nevertheless, in 15 recent years it has become increasingly clear that these communities contain many, if not a 16 majority, of species that have survived multiple glacial cycles over many millions of years 17 and undergone evolutionary radiation on the continent itself rather than recolonizing from 18 extra-continental refugia (Convey & Stevens, 2007; Convey et al., 2008; Fraser et al., 2014). 19 With this background, high levels of endemism characterize the majority of groups that 20 dominate the Antarctic terrestrial fauna, including in particular Acari, Collembola, Nematoda 21 and Tardigrada (Pugh & Convey, 2008; Convey et al., 2012). 22 The continent of Antarctica is ice-bound, and surrounded and isolated from the other 23 Southern Hemisphere landmasses by the vastness of the Southern Ocean.

Sea ice cover limits light, and hence primary production and food supply. Plankton, carried by currents from open water to areas under the sea ice, provides a transitory food resource that is spatially and temporally variable. We recorded epifaunal abundances at 17 sites in McMurdo Sound, Antarctica, over 12 yr, and found differences in communities based on location and time. The differences in location support patterns observed in long-term infaunal studies, which are primarily driven by currents, food availability, and larval supply. The temporal differences, highlighting 2004 and 2009 as years of change, match the altered persistence of sea ice in the region, caused by the appearance and disappearance of mega-icebergs. Benthic communities in Antarctica show temporal shifts in The temporal changes were driven by changes in response to changes in sea ice and planktonic food supply. abundance of species that filter feed on large partic- Zyzzyzus parvula is one key species. ulates.

    The Pennsylvania State University The Graduate School Department of Civil and Environmental Engineering ARE THE DRY VALLEYS GETTING WETTER? A PRELIMINARY ASSESSMENT OF WETNESS ACROSS THE MCMURDO DRY VALLEYS LANDSCAPE A Thesis in Civil Engineering by Zachary L. Langford Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science May 2013 ii The thesis of Zachary L. Langford was reviewed and approved* by the following: Michael N. Gooseff Associate Professor of Civil Engineering Thesis Advisor Alfonso I. Mejia Assistant Professor of Civil Engineering Peggy A. Johnson Professor of Civil Engineering Head of the Department of Civil Engineering *Signatures are on file in the Graduate School iii ABSTRACT Liquid water is scarce across the landscape of the McMurdo Dry Valleys (MDV), Antarctica and is associated with soils that are adjacent to streams and lakes, during the annual thaw season. However, seeps, water tracks, and wet patches have been observed at several other locations as well. The source of water for these is likely generated by a combination of infiltration from melting snowpacks, melting of pore ice at the ice table beneath the water tracks, and melting of buried segregation ice formed during winter freezing. We are using high resolution (<1m pixel) remote sensing data gathered several times per week in the MDV region to determine the spatial and temporal distribution of wet soils. We assess the spatial consistency with which these wet soils occur for the 2008-2009 to 2011-2012 austral summers with complete coverage and partial coverage for 2003-2004 and 2006-2007 austral summers using a land cover classification.

The two events are, in effect, a two-step review—the first in 15 years—that, when done, will help shape what the United States should do in Antarctica and how it should do it. The first step was a 90-page report published in April by the Committee on Fundamental Science of the President’s National Science and Technology Council. Titled "United States Antarctic Program," (USAP) the report concludes that "essential elements of U.S. national and scientific interests are well-served by continued involvement in scientific activity in the Antarctic as carried out by the USAP.
