Dissolved gases in hydrothermal plumes from Artic vent fields
(The University of Bergen, 2013-10-30)
Recent discoveries of active vent fields on slow and ultraslow spreading ridges have revealed that hydrothermal activity is more common than previously assumed. In the Norwegian-Greenland Sea, two such vent fields are ...
Correlated ionization processes in atoms and molecules
(The University of Bergen, 2013-09-27)
This thesis is composed of five scientific papers written between 2009 and 2013. The focus of this work is on various photo-ionization processes in small atoms and molecules. The strong field phenomenon called “atomic ...
Palaeolimnological responses of nine North African lakes in the CASSARINA Project to recent environmental changes and human impact detected by plant macrofossil, pollen, and faunal analyses
This paper presents multi-proxy palaeolimnological analyses from recent sediments in the nine CASSARINA lakes in northernmost Africa, three from each of Morocco, Tunisia, and Egypt. The lakes are diverse, ranging from ...
PEPT: an invaluable tool for 3-D particle tracking and CFD simulation verification in hydrocyclone studies
(EDP Sciences, 2013)
Particle tracks in a hydrocyclone generated both experimentally by positron emission particle tracking (PEPT) and numerically with Eulerian-Lagranian CFD have been studied and compared. A hydrocyclone with a cylinder-on-cone ...
Modeling hydrate phase transitions using mean-field approaches

Skaleringskriterier for vannflømming i sandstein og tertiær oljeutvinning ved bruk av CO2
(The University of Bergen, 2011-06-14)
I forbindelse med studier for økt oljeproduksjon utføres kjerneanalyse på kjerneprøver som representerer en liten fraksjon av oljereservoarer. I korte kjerneprøver vil de kapillære endeeffektene påvirke flømmingene, noe ...
Isotopic composition of Pb in tree rings of Norway spruce (Picea abies) from the Fensfjorden area, western Norway
(The University of Bergen, 2012-06-01)
The annual growth of tree rings makes the trees as possible archive of the past atmospheric pollution. However, several aspects addressed in literature such as post-depositional mobility of Pb, intra-ring heterogeneity ...
Life after fire: smoke and ash as germination cues in ericads, herbs and graminoids of northern heathlands
<p>Question: What is the impact of the fire cues smoke and ash on seed germination of important functional groups in the heathland system, namely ericads, herbs and graminoids? We predict that if germination from heathland ...
Kvartærgeologisk kartlegging og isavsmeltingshistorie i Sunndalen, Møre og Romsdal
(The University of Bergen, 2013-06-03)
The age of three terminal glacial deposits located at Hoås, Gikling and Romfo in the Sunndalen valley, Møre & Romsdal, has been uncertain. The aim of this study has been to document these deposits to clarify the chronology ...
Hydrate Monitoring using Capacitive Sensors
(The University of Bergen, 2013-06-02)
Gas hydrates are of particular interest in petroleum industry since their formation during oil-production can be a major risk factor. Gas hydrates can block pipelines, interrupt production, and in worst case even cause ...
