Rock physics and seismic AVA analysis of gas hydrate-bearing sediments
(Master thesis, 2014-06-02)Large amount of natural gas are present in submarine sediments and permafrost areas in the form of gas hydrates. Gas hydrates are a large potential future energy resource, and may contribute to the methane balance in the ... -
Rock physics interpolation Used for velocity modeling of chalks: Ontong Java plateau example
(Peer reviewed; Journal article, 2010)Chalks are pelagic carbonate sediments that are deposited in deep-water environments. Their elastic behaviour is controlled by a combination of depositional conditions and subsequent diagenesis. In this paper, we incorporate ... -
Rock Physics Templates for 4D Seismic Reservoir Monitoring: A case study from Yttergryta field in the Norwegian Sea
(Master thesis, 2014-06-02)Time-lapse 3D seismic which geoscientists often abbreviate to 4D seismic has the potential to monitor changes especially in pore pressure, hydrocarbon and brine saturation in a reservoir due to production or water/gas ... -
Rock sponges (lithistid Demospongiae) of the Northeast Atlantic seamounts, with description of ten new species
(Journal article; Peer reviewed, 2020)Background Lithistid demosponges, also known as rock sponges, are a polyphyletic group of sponges which are widely distributed. In the Northeast Atlantic (NEA), 17 species are known and the current knowledge on their ... -
A Role for Weak Electrostatic Interactions in Peripheral Membrane Protein Binding
(Peer reviewed; Journal article, 2016-03)Bacillus thuringiensis phosphatidylinositol-specific phospholipase C (BtPI-PLC) is a secreted virulence factor that binds specifically to phosphatidylcholine (PC) bilayers containing negatively charged phospholipids. ... -
The role of acetylation of histone H3 lysine 27 in enhancer function
(Doctoral thesis, 2020-12-09)The histone modification H3K27ac is a hallmark of active enhancers. However, its role in enhance-specific activity remains obscure. We applied mass spectrometry-based quantitative interaction proteomics to determine proteins ... -
The role of air–sea coupling on November–April intraseasonal rainfall variability over the South Pacific
(Journal article; Peer reviewed, 2022)We investigate the impact of resolving air-sea interaction on the simulation of the intraseasonal rainfall variability over the South Pacific using the ECHAM5 atmospheric general circulation model coupled with the ... -
The Role of Atlantic Heat Transport in Future Arctic Winter Sea Ice Loss
(Peer reviewed; Journal article, 2019-05-14)During recent decades Arctic sea ice variability and retreat during winter have largely been a result of variable ocean heat transport (OHT). Here we use the Community Earth System Model (CESM) large ensemble simulation ... -
Role of atmosphere-ocean interactions in supermodeling the tropical Pacific climate
(Peer reviewed; Journal article, 2017-12-29)The supermodel strategy interactively combines several models to outperform the individual models comprising it. A key advantage of the approach is that nonlinear improvements can be achieved, in contrast to the linear ... -
Role of Atmosphere-ocean-ice Interaction in the Linkage between December Bering Sea Ice and Subsequent February Surface Air Temperature Over North America
(Journal article; Peer reviewed, 2023)This study revealed that the interannual variations of December Bering Sea ice and subsequent February surface air temperature (SAT) over North America are significantly correlated during 2000/01-2020/21, which is not the ... -
The role of authigenic sulfides in immobilization of potentially toxic metals in the Bagno Bory wetland, southern Poland
(Peer reviewed; Journal article, 2015-10)The supply of Cd, Cu, Fe, Pb, Zn, and Tl into a wetland in the industrial area of Upper Silesia, southern Poland via atmospheric precipitation and dust deposition has been counterbalanced by the biogenic metal sulfide ... -
The role of dietary methionine concentrations on growth, metabolism and N-retention in cobia (Rachycentron canadum) at elevated water temperatures
(Peer reviewed; Journal article, 2019-04)This study determined impacts of dietary methionine concentrations at two temperatures on growth, feeding efficiency and N‐metabolites in juvenile cobia. Methionine concentrations of the experimental diets were deficient ... -
Role of EPAC in cAMP-mediated actions in adrenocortical cells
(Peer reviewed; Journal article, 2016-06-13)Adrenocorticotropic hormone regulates adrenal steroidogenesis mainly via the intracellular signaling molecule cAMP. The effects of cAMP are principally relayed by activating protein kinase A (PKA) and the more recently ... -
The Role of Humans in Complex ICT Systems
(Master thesis, 2016-10-16)In the modern world, companies, regardless of their type of business, rely on information and communications technology (ICT) systems to carry out their everyday operations. The ICT systems have been developed over time ... -
The role of intraspecific variability in driving community trait shifts along temperature and precipitation gradients in alpine and boreal semi-natural grasslands
(Master thesis, 2017-12-15)Climate projections show that western Norway will experience warmer and wetter conditions in the future. Investigations of trait changes with these climatic gradients can be used to understand the responses of species, ... -
The role of land and ocean evaporation on the variability of precipitation in the Yangtze River valley
(Peer reviewed; Journal article, 2019-06-04)The Yangtze River valley (YRV) experiences large intraseasonal and interannual precipitation variability, which is mainly due to East Asian monsoon influence. The East Asian monsoon is caused by interaction of many processes ... -
