  1. 6. Contributions of Event Water to Streamflow in an Agricultural Catchment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Johannes Hagby; [2018]
    Keywords : Isotopic hydrograph separation; tracer; event water; pre-event water; sequential rainfall collector; Hydrograf separation; spårämne; eventvatten; pre-event vatten; sekventiell regnuppfångare;

    Abstract : In agricultural catchments, hydrological processes play an important role in the export of nutrients. Water that enters a catchment during a rain event (event water) can have different flow paths and residence times. READ MORE

  3. 7. Peloponnesian Stalagmites and Soda Straw Stalactites as Climate Archives : Stable Isotopes in New Speleothem Material from Kapsia Cave, Peloponnese, Greece

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Linn Haking; [2017]
    Keywords : Stable Isotopes; Stalagmite; Soda Straw Stalactites; Climate Archive; Climate Variability; The Amount Effect; Isotopic Fractionation; Kapsia Cave; Peloponnese; Greece; Mediterranean;

    Abstract : This study presents results from stable isotope analyses of a modern stalagmite and three soda straw stalactites from Kapsia Cave, the Peloponnese, Greece. The resulting values from the stalagmite are put into context of local meteorological data, as well as previous research from Kapsia Cave. READ MORE

  4. 8. Neolithic farmers in Poland - A study of stable isotopes in human bones and teeth from Kichary Nowe in the south of Poland

    University essay from Stockholms universitet/Arkeologiska forskningslaboratoriet

    Author : Staffan Lundmark; [2016]
    Keywords : stable isotopic study; archaeological science; Neolithic in southern Poland; Kichary Nowe 2 grave-field; diet study on Neolithic bone material; stabila isotoper studie; laborativ arkeologi; neolitikum i södra Polen; Kichary Nowe 2 gravfält; dietstudie på neolitiskt benmaterial;

    Abstract : The diet of the Stone Age cultures is a strong indicator to the social group, thus farmers and hunters can be distinguished through their diet. There is well-preserved and well excavated Polish skeletal material available for such a study but the material has not previously been subject to stable isotopes analyses and therefore the questions of diets has not been answered.

  5. 9. A high-resolution oxygen isotope reconstruction of humidity changes in central Sweden during the late Holocene

    University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Simon Larsson; [2014]
    Keywords : stable; isotope; oxygen; carbonate; humidity; sweden; holocene;

    Abstract : Records of stable oxygen isotope variations from a variety of proxies have been used in palaeoclimatic research since the 1950’s. Several studies have applied stable isotope analysis of lake sediments to reconstruct past climate changes in central and northern Sweden, including a study of Lake Blektjärnen in Jämtland, central Sweden, by Andersson (2010).

  6. 10. H and O stable isotope compositions of different soil water types : effect of soil properties

    University essay from SLU/Dept. of Soil and Environment

    Author : Martine Stoll; [2014]
    Keywords : soil water; centrifugation; cryogenic vacuum distillation; H and O stable isotopes; soil processes;

    Abstract : Stable isotope compositions of water are usually investigated to trace the flow of meteoric water from precipitation through the soil matrix to ground water, stream water and plants. This tracer data can much reduce model uncertainty and give further details on water and solute movement. READ MORE
