Northern hemisphere glaciation during the globally warm early late Pliocene
The early Late Pliocene (3.6 to ,3.0 million years ago) is the last extended interval in Earth’s history when atmospheric CO2 concentrations were comparable to today’s and global climate was warmer. Yet a severe global ...
Refining benthic foraminiferal Mg/Ca-temperature calibrations using core-tops from the western tropical Atlantic: Implication for paleotemperature estimation
(WileyAmerican Geophysical UnionGeochemical Society, 2013-04)
Benthic foraminiferal Mg/Ca has been shown to have great potential as a proxy for reconstructing deep water temperatures. However, the exact relationship between Mg uptake in benthic foraminifera and temperature is still ...
Simulating the climatic response of Hardangerjøkulen in southern Norway since the Little Ice Age
(The University of Bergen, 2014-05-24)
Glacier and ice cap volume changes currently amount to half of the total contribution from the cryosphere to sea-level rise. Ice caps and their outlet glaciers are dynamically different from the Greenland and Antarctic ice ...
Petrophysical Properties of Deformed Sandstone Reservoir
(The University of Bergen, 2012-06-21)
Small scale deformation structures that mostly occur in highly porous rocks are called deformation bands. Petrophysical characteristics of deformation bands are different from those of host rock and they can act as ...
Calibration, validation and application of the foraminiferal Mg/Ca. Reconstructing the intermediate water masses structure and origin in the Western Tropical Atlantic
(The University of Bergen, 2015-05-22)
<p>The Atlantic Meridional Overturning Circulation (AMOC) plays a central role in the northward distribution of heat. It is a key mechanism in the climatic system that needs to be further understood. Most studies focused ...
On the evolution of the North Atlantic -from continental collapse to oceanic accretion
(The University of Bergen, 2013-10-23)
<p>The North Atlantic between Iceland and Svalbard and surrounding continental areas represent an ideal laboratory for studying plate tectonic processes, due to the presence of well exposed continent-continent collision ...
Identifying flood deposits in lake sediments: Changing frequencies and potential links to long-term climate change
(The University of Bergen, 2011-05-26)
This thesis consists of an introduction and three individual papers that investigate the possibility for identifying the sedimentary imprint of catchment processes in lake sediments, emphasising on extreme events and in ...
From mountains to basins: geochronological case studies from southwestern Norway, Western Australia and East Antarctica
(The University of Bergen, 2012-03-02)
Ice-sheet dynamics and glacial development of the Norwegian continental margin during the last 3 million years
(The University of Bergen, 2007-06-29)
This thesis is mainly about the dynamics of the palaeo-ice sheets that covered Scandinavia, Barents Sea and Svalbard during the last glaciation. Morphological interpretation of regional and detailed bathymetric data sets ...
Kartlegging av område med potensiell skredfare i Os kommune, Hordaland
(The University of Bergen, 2011)
Frå 2010 trådde plan- og bygningslova i kraft. Den seier at risiko- og sårbarheitanalyse med omsyn på mellom anna skred skal utførast i samanheng med nybygging og merkast på aktsemdkart. Dette er bakgrunnen for at Os ...
