Review of the Tanzanian prawn Fishery
(Master thesis, 2011-05-30)A review of the prawn fishery of Tanzania from its development in early 1980's to closure in 2008 has been performed based on three major data sets; industrial prawn and fish catch data from Fisheries Division, river ... -
A review of the use of microplastics in reconstructing dated sedimentary archives
(Journal article; Peer reviewed, 2022)Buried microplastics (plastics, <5 mm) have been documented within the sediment column of both marine and lacustrine environments. However, the number of peer-review studies published on the subject remains limited and ... -
Revised Minoan eruption volume as benchmark for large volcanic eruptions
(Journal article; Peer reviewed, 2023)Despite their global societal importance, the volumes of large-scale volcanic eruptions remain poorly constrained. Here, we integrate seismic reflection and P-wave tomography datasets with computed tomography-derived ... -
A revised ocean glider concept to realize Stommel's vision and supplement Argo floats
(Journal article; Peer reviewed, 2020-02)This paper revisits Stommel's vision for a global glider network and the Argo design specification. A concept of floats with wings, so-called slow underwater gliders, is explored. An analysis of the energy or power consumption ... -
Revised ΔR values for the Barents Sea and its archipelagos as a pre-requisite for accurate and robust marine-based 14C chronologies
(Journal article; Peer reviewed, 2022)The calibration of marine 14C dates requires the incorporation of regionally specific marine reservoir offsets known as ΔR, essential for accurate and meaningful inter-archive comparisons. Revised, regional ΔR (‘ΔRR’) ... -
Revision of the genus Exsuperantia Özdikmen, 2009 (Tetractinellida: Phymaraphiniidae) with description of a new species from the Atlantic Ocean
(Peer reviewed; Journal article, 2019)Phymaraphiniidae Schrammen 1924 (Porifera: Astrophorina) is a family of lithistid demosponges that has received little attention in the past decades. The systematic problems within this family have not been addressed for ... -
Revisiting Language Support for Generic Programming: When Genericity Is a Core Design Goal
(Journal article; Peer reviewed, 2022)Context Generic programming, as defined by Stepanov, is a methodology for writing efficient and reusable algorithms by considering only the required properties of their underlying data types and operations. Generic ... -
Revisiting transverse momentum broadening in dense QCD media
(Journal article; Peer reviewed, 2021)We reconsider the problem of transverse momentum broadening of a highly energetic parton suffering multiple scatterings in dense colored media, such as the thermal quark-gluon plasma or large nuclei. In the framework of ... -
Reworking of atmospheric sulfur in a Paleoarchean hydrothermal system at Londozi, Barberton Greenstone Belt, Swaziland
(Peer reviewed; Journal article, 2016-07)Anomalous fractionation of the minor isotopes of sulfur (Δ33S, Δ36S) in Archean pyrite is thought to reflect photochemical reactions in an anoxic atmosphere, with most samples falling along a reference array with Δ36S/Δ33S ... -
Rheological properties of hydrophobically modified anionic polymers: The effect of varying salinity in polymer solution
(Master thesis, 2017-06-16)A new class of polymers, named ‘hydrophobically modified water-soluble polymers’, has been developed as an alternative to the more commonly used polyelectrolytes in enhanced oil recovery (EOR) applications. These polymers ... -
Rheology of Synthetic Polymers in Porous Media
(Master thesis, 2014-06-02)This master thesis is written out of the Centre for Integrated Petroleum Research (UNI CIPR) at the University of Bergen (UiB). The aim of this study has been to describe the polymer rheology of the high molecular weight ... -
Rhythmic Clock Gene Expression in Atlantic Salmon Parr Brain
(Journal article; Peer reviewed, 2021)To better understand the complexity of clock genes in salmonids, a taxon with an additional whole genome duplication, an analysis was performed to identify and classify gene family members (clock, arntl, period, cryptochrome, ... -
Ridge Extraction, and Illustrative Visualization of an FTLE Flow Field.
(Master thesis, 2012-06-01)Illustrative visualization of a flow is an area that is proving to be interesting and in later years something that have been somewhat explored, it can provide some very interesting results and in this thesis we find the ... -
Rift kinematics preserved in deep-time erosional landscape below the northern North Sea
(Journal article; Peer reviewed, 2022)Our understanding of continental rifting is, in large parts, derived from the stratigraphic record. This record is, however, incomplete as it does not often capture the geomorphic and erosional signal of rifting. New 3D ... -
Rigorous derivation of some asymptotic models for free water surfaces and interfaces
(Doctoral thesis, 2024-04-26)Opprinnelsen til moderne matematisk hydrodynamikk kan spores tilbake til 1700-tallet. I 1757 publiserte Euler artikkelen der han introduserte ligninger, i dag kjent som Euler likningene, som kan beskrive væskedynamikk [31]. ... -
Rigorous estimates on mechanical balance laws in the Boussinesq–Peregrine equations
(Journal article; Peer reviewed, 2024)It is shown that the Boussinesq–Peregrine system, which describes long waves of small amplitude at the surface of an inviscid fluid with variable depth, admits a number of approximate conservation equations. Notably, this ... -

Rise and fall of sea ice production in the Arctic Ocean’s ice factories
(Journal article; Peer reviewed, 2022)The volume, extent and age of Arctic sea ice is in decline, yet winter sea ice production appears to have been increasing, despite Arctic warming being most intense during winter. Previous work suggests that further warming ... -
Risiko for spredning av flammer og røyk gjennom brannskiller ved endringer i bruk av sprinkler og røykkontroll i boligkvarter på petroleumsinnretninger.
(Master thesis, 2016-09-27)Målet med oppgaven har vært å undersøke hvordan endringer i bruk av sprinkler og brannspjeld i boligkvarter på petroleumsinnretninger, har påvirket risiko for spredning av flammer og røyk gjennom ventilasjonskanaler. ... -
Risk of Leakage versus Depth of Injection in Geological Storage
(Peer reviewed; Journal article, 2009-02)One of the outstanding challenges for large-scale CCS operations is to develop reliable quantitative risk assessments with a focus on leakage of both injected CO2 and displaced brine. A critical leakage pathway is associated ...
