    Stable-isotope records from Dronning Maud Land, Antarctica (2002)
    Cambridge University Press
    Details
    Publication Date: 2002-01-01
    Description: The European Project for Ice Coring in Antarctica (EPICA) includes a comprehensive pre-site survey on the inland ice plateau of Dronning Maud Land. This paper focuses on the investigation of the 18O content of shallow firn and ice cores. These cores were dated by profiles derived from dielectric-profiling and continuous flow analysis measurements. the individual records were stacked in order to obtain composite chronologies of 18O contents and accumulation rates with enhanced signal-to-noise variance ratios. These chronologies document variations in the last 200 and 1000 years. The18O contents and accumulation rates decreased in the 19th century and increased during the 20th century. Using the empirical relationships between stable isotopes, accumulation rates and the 10 m firn temperature, the variation of both parameters can be explained by the same temperature history. But other causes for these variations, such as the build-up of the snow cover, cannot be excluded. A marked feature of the 1000 year chronology occurs during the period AD 1180–1530 when the 18Ocontents remains below the long-term mean. Cross-correlation analyses between five cores from the Weddell Sea region and Dronning Maud Land show that 18O records can in some periods be positively correlated and in others negatively correlated, indicating a complex climatic history in time and space.

    Surface accumulation on Foundation Ice Stream, Antarctica (1999)
    Cambridge University Press
    Details
    Publication Date: 1999-01-01
    Description: This paper presents new data, derived from an analysis of 16 firn cores, on the distribution of the accumulation rate and 18O content of near-surface layers in the eastern part of the Ronne Ice Shelf, Antarctica. The firn cores were drilled along the traverse route of the Filchner-V-Campaign in 1995. The traverse followed an ice flowline of the Foundation Ice Stream and reached the margin of the inland ice, an area which has not yet been investigated. On the ice shelf the accumulation rates decrease with distance from the coast. Ascending to the inland ice the accumulation rates again reach almost coastal values. This regional distribution is in agreement with the temperature gradient along the traverse. The 18 content of the near-surface layers is closely related to the 10 m firn temperature. They strongly decrease from the grounding line towards the inland ice. At the southernmost site at 1100 ma.s.l, the mean δ18O value of the firn decreases to –40‰. Ice with that isotopic signature was found in cores from the central part of the Ronne Ice Shelf just above the marine ice layer, indicating that it originates from this area. All ice deposited as snow further south was melted beneath the ice shelf after passing the grounding-line area. The time series of accumulation rate and 18O content reveal no climatic trend during the last 30-50 years.

    Die Pegelstation Vernagtbach (Ötztaler Alpen). Planung, Bau und Messergebnisse (1976)

    Publication Date: 2019-07-17
    Description: This paper describes the extraordinary difficulties met in gauging glacier streams and establishes criteria that have to be fulfilled for a correct determination of glacier run off. Discussion of the hydraulic principles of gauging in tranquil and rapid flow shows why the latter is to be favored for glacier streams. The concept of the station at Vernagtbach, the original stream bed, considerations of proper dimensioning and characteristics of the construction of the gauging channel are described in detail. A brief history is given of planning, organization and technology involved. The water level is recorded by two floats and one pneumatic gauge which together provide uninterrupted and trouble-free records. The rating curve was determined with current meters and shows an unambiguous relation between water level and discharge with little scattering of calibration values. Temporary changes of flow conditions up-stream of the station do not have any noticeable effect on the water level in the channel. The discharge records of the summers 1974-1976 are presented and discussed. The maximum mean summer discharge was 1.33 m**3/s in June-September 1975; extreme mean monthly discharge was found in July 1976 with 2.51 m**3/s, the highest daily mean was 4.76 m**3/s and the maximum hourly mean was found at 7.23 m**3/s. The discharge conditions of the summers of 1974 and 1975 are very simiIar, while in the summer of 1976 they differed completely as far as seasonal and mean daily hydrographs are concerned: in 1975, 42 % of summer discharge was recorded in June and July compared to 76 % in 1976. The analysis of the hydrographs gives valuable clues to the mass and heat balances of the glacier.

    Description: The Vernagtferner region has a long tradition of glaciological research performed by groups from Munich. It started in 1889, when Prof. Sebastian Finsterwalder from the Technical University in Munich produced the first map of a complete glacier based on terrestrial photogrammetry. Since then, numerous maps of the glacier have been made, describing the change in surface elevation for more than a century. These maps form the basis of the geodetic method of glacier mass balance determination, which provides volume changes as average data for the period between two surveys, i.e. typically for 10 years. Since the start of the glaciological method on Vernagtferner in 1964, annual as well as winter and summer mass balance data are available continuously. But only since 1973, the construction of the Vernagtbach station, approximately 1 km below the glacier margin at that time, provided the means to record a larger number of hydrological and meteorological parameters with a temporal resolution of typically 1 hour.

    Description: From 1974 to 1982 repeated tracer tests using fluorescent dyes were carried out in the highly glaciated drainage basin of Vernagtbach. These tests enabled the quantitative determination of the runoff in the forefield of the Vernagtferner, the calculation of travel times of the stream water and estimations of the relative contributions to the entire runoff originating from individual streams. In addition, tracer tests were carried out in the firn area of the glacier resulting in data concerning the storage and travel time of meltwater inside the glacier.
