Geovetenskaplig Studiepraktik
Deglaciationen av ett område på västra Grönland En geomorfologisk studie kring Aajuitsup Tasia William Lidberg Examensarbete i Geovetenskap/ Naturgeografi 15 hp Avseende kandidatexamen Rapporten godkänd: 8 november 2011 Handledare: Rolf Zale Deglaciation in an area on west Greenland A Geomorphological studie William Lidberg Abstract The aim of this report is to describe the deglaciation in an area on west Greenland in the vicinity of Kangerlussuaq. To do this, the geomorphological landforms were mapped by studying areal photographs and by a two week field study where key areas were examiend. The landforms were transferred to a map using ArcGis and each key area were interpreted.The majority of the geomorphological formations were formed during the last deglaciation and consists of morain ridges, kettle topography in both till and glacifluvium, glacifluvial deltas, two fossil sandurs, and lateral terraces. Based on key areas and an inversion model a geomorphological map was created to illustrate the deglaciation, using the least complex explanation of the genesis of the landforms. The results show that the ice played a major role by damming lakes which enabled formation of many meltwater chanels and delta formations on higher elevations. The morain ridges and lateral terraces showed the extent of the ice margin during the halts in the ice retreat. The deglaciation was dated with help from earlier studies and the conclusion was that the deglaciation started between 7900 and 6700 yr BP. And the area was free from ice 7100-6500 yrs BP. Keywords: Deglaciation, Geomorphology, Greenland, Kangerlussuaq Förord Sommaren 2010 gick kursen arktiska miljöer på Grönland men jag kunde inte delta så när David Berg lade fram förslaget att göra våra examensarbeten där tvekade jag inte. -

The Concentration of in Situ 10Be in Fluvial Sediments As a Tool for Deciphering 6 My of Greenland Ice Sheet History from a Marine Sediment Core
THE CONCENTRATION OF IN SITU 10BE IN FLUVIAL SEDIMENTS AS A TOOL FOR DECIPHERING 6 MY OF GREENLAND ICE SHEET HISTORY FROM A MARINE SEDIMENT CORE A Progress Report By Alice Heller Nelson To The Faculty of the Geology Department Of The University of Vermont 4th of October 2012 Accepted by the Faculty of the Geology Department, the University of Vermont, in partial fulfillment of the requirements for the degree of Master of Science specializing in Geology. The following members of the Thesis Committee have read and approved this document before it was circulated to the faculty: _________________________ Chair Jason D. Stockwell, Ph.D. _________________________ Advisor Paul R. Bierman, Ph.D. _________________________ Andrea Lini, Ph.D. Date Accepted: ________________ I. Introduction 1.1. Motivation My research involves measuring the concentration of in situ 10Be in glacio- fluvial sediments from Greenland and an adjacent ocean sediment core spanning the past 6 Myr (Figure 1). Knowing the concentration of 10Be in modern continental sediment samples will help me interpret the down core record, which may provide a new way of estimating timing of Greenland Ice Sheet (GIS) inception and inferring past ice extent and erosivity. Linking this ice sheet variability with records of past climate change may help to determine thresholds for ice loss and regrowth, which is an important step towards predicting how the ice sheet might respond to future climate change. 1.2. Project Goals The first component of my research is to measure the 10Be concentration in sediment sourced from different places on the Greenlandic landscape. Ice shields rock from cosmic rays, so I expect sediments sourced from glaciated versus ice-free terrain will contain different amounts of 10Be and that sediments from different source areas will mix as they are transported through the landscape. -

Goose News The newsletter of the Goose & Swan Monitoring Programme Issue no. 9, Autumn 2010 Half a century and going strong...50 years of IGC counting Autumn 2009, saw the 50th complete census of Pink -footed and Greylag Goose populations in Britain. The history of the census provides a revealing story. In the 1930s in North America, there was considerable concern at real declines in the numbers of geese reported and, in Europe, a dramatic decline in Brent Geese had been observed. In Britain and Ireland, the status of goose populations was based l argely on local knowledge with little coordination. There were, for example, records that Bean Geese were formerly very common, and that Pink-footed Geese were uncommon, but the true status of these populations in the 1930s was poorl y known. In The status and distribution of wild geese and duck in Scotland by John Berry (1939), perhaps the first attempt to establish the status of wildfowl in that country, the author documented the then known status and distribution of geese. Through necessity, this was larg ely based on anecdotal records, although some counts were included, as systematic counting had yet to be established. The Wildfowl Count network, established in 1947 by the International Wildfowl Enquiry Committee, aimed to cover as many waterbodies (or w etlands) as possible once in each winter month (September to March) and, in 1954, WWT took over responsibility for its organisation. In order to provide a basis for conservation planning following the 1954 Protection of Birds Act, the results of the first 14 years of counts were published in Wildfowl in Great Britain by George Atkinson - Willes; this proved to be the most comprehensive survey of wildfowl habitats, stocks and prospects. -
