GOODWIN1 and JOHN HELLSTROM2 1Environmental and Climate Change Research Group, School of Environmental and Life Sciences, University of Newcastle, Callaghan, NSW 2308, Australia 2School of Earth Sciences, University of Melbourne, Parkville, VIC 3010, Australia [email protected] Abstract: The late Quaternary glacial history of the Amery Oasis, and Prince Charles Mountains is of significant interest because about 10% of the total modern Antarctic ice outflow is discharged via the adjacent Lambert Glacier system. A glacial thrust moraine sequence deposited along the northern shoreline of Radok Lake between 20–10 ka BP, overlies a layer of thin, aragonite crusts which provide important constraints on the glacial history of the Amery Oasis. The modern Radok Lake is fed by the terminal meltwaters of the alpine Battye Glacier. The aragonite crusts were deposited in shallow water of ancestral Radok Lake 53 ka BP,during the A3 warm event in Isotope Stage 3. Oxygen isotope (d18O) analysis of the last glacial-age aragonite crusts 18 indicates that they precipitated from freshwater with a d OSMOW composition of -36%, which is 8% more depleted than the present water (-28%) in Radok Lake. A regional oxygen isotope (d18O) and elevation relationship for snow is used to determine the source of meltwater and glacial ice in Radok Lake during the A3 warm event.

Klein Vatche P. Tchakerian Mahlon Kennicutt Head of Department, Douglas Sherman December 2005 Major Subject: Geography iii ABSTRACT Investigation of Glacial Dynamics in Lambert Glacial Basin Using Satellite Remote Sensing Techniques. Jaehyung Yu, B.S., Chungnam National University; M.S., Chungnam National University Chair of Advisory Committee: Dr. Hongxing Liu The Antarctic ice sheet mass budget is a very important factor for global sea level. An understanding of the glacial dynamics of the Antarctic ice sheet are essential for mass budget estimation. Utilizing a surface velocity field derived from Radarsat three-pass SAR interferometry, this study has investigated the strain rate, grounding line, balance velocity, and the mass balance of the entire Lambert Glacier – Amery Ice Shelf system, East Antarctica. The surface velocity increases abruptly from 350 m/year to 800 m/year at the main grounding line. It decreases as the main ice stream is floating, and increases to 1200 to 1500 m/year in the ice shelf front.

  • Crossover Analysis of Lambert-Amery Ice Shelf Drainage Basin for Elevation Changes Using Icesat GLAS Data
    Crossover Analysis of Lambert-Amery Ice Shelf Drainage Basin for Elevation Changes Using ICESat GLAS Data Dr. SHEN Qiang, Prof. E. Dongchen and Mr. JIN Yinlong (China P. R. Key Words: remote sensing; Lambert-Amery System (LAS); ICESat; GLAS (The Geoscience Laser Altimeter System); elevation change; mass balance; crossover analysis SUMMARY In IPCC Report, the climate change issue has become important part of the larger challenge of sustainable development. The widespread retreat or dilation of glaciers is considered good response to the climate change, such as temperature rise, sea-level rise, etc.. As the largest glacier-ice shelf system in Antarctica, the Lambert Glacier-Amery Ice Shelf system plays an important role in contributions to ice drainage in East Antarctica, which may be make large contributions to rising sea level as well as climate environment. For the ICESat GLAS can determine ice-sheet elevation with an intrinsic precision of better than 10 cm and associated temporal change at the centimeter per year level. So it can be used to measure seasonal and interannual variability of ice-sheet topography in sufficient spatial and temporal detail. In general, Estimates of the global contribution of glaciers to sea level rise are traditionally based on labor-intensive mass-balance (snow/ice input minus ice/water output) measurements on the glacier surface. In this paper, crossover analysis method is addressed for detection of elevation change in Lambert-Amery system. It is differenced measurements at track intersection points that occur with the crossovers of ascending and descending orbit nodes. Common effects will cancel in the crossover formation but temporal effects will remain.

  • Spatial Variations in the Geochemistry of Glacial Meltwater Streams in the Taylor Valley, Antarctica KATHLEEN A

Because of the low precipitation rates, streams originate from glacial meltwater and flow to closed-basin lakes on the valley floor. Water samples have been collected from the streams in the Dry Valleys since the start of the McMurdo Dry Valleys Long-Term Ecological Research project in 1993 and these have been analysed for ions and nutrient chemistry. Controls such as landscape position, morphology of the channels, and biotic and abiotic processes are thought to influence the stream chemistry. Sea-salt derived ions tend to be higher in streams that are closer to the ocean and those streams that drain the Taylor Glacier in western Taylor Valley. Chemical weathering is an important process influencing stream chemistry throughout the Dry Valleys. Nutrient availability is dependent on landscape age and varies with distance from the coast.
