  1. 1. Integrated geophysical-geochemical methods for archaeological prospecting

    Författare :Kjell Persson; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Geophysics; geophysical; geochemical; prospecting; archaeology; electric; magnetometric; Geofysik; Geophysics; Geofysik;

    Sammanfattning : A great number of field measurements with different methods and instruments were conducted in attempts to develop a method for an optimal combination of various geochemical and geophysical methods in archaeological prospecting. The research presented in this thesis focuses on a study of how different anthropogenic changes in the ground can be detected by geochemical and geophysical mapping and how the results can be presented.

  2. 2. Two topics in electromagnetic radiation field prospecting

    Författare :Bruno Nilsson; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : Different kinds of electrical methods have been used for a considerable time in the field of Applied Geophysics. In common these methods have almost exclusively been based on stationary or slow-varying electromagnetic fields. LÄS MER

    Sammanfattning : The present paper is an introduction to and a summary of a thesis consisting of the following papers:1. Scattering of electromagnetic waves by a perfectly conducting half plane below a stratified overburden. Radio Sci. (1978), Vol. LÄS MER

  5. 5. Across landscapes and seascapes : The movement ecology of diving and flying guillemots and gulls during breeding

    Författare :Thomas J. Evans; Evolutionär ekologi; []
    Nyckelord :Uria aalge; Larus fuscus; Laridae; animal flight; foraging ecology; movement ecology; seabirds;

    Sammanfattning : Most seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. LÄS MER
