Overview of the Norwegian Earth System Model (NorESM2) and key climate response of CMIP6 DECK, historical, and scenario simulations
(Journal article; Peer reviewed, 2020-12)The second version of the coupled Norwegian Earth System Model (NorESM2) is presented and evaluated. NorESM2 is based on the second version of the Community Earth System Model (CESM2) and shares with CESM2 the computer ... -
Overview of the PALM model system 6.0
(Journal article; Peer reviewed, 2020)In this paper, we describe the PALM model system 6.0. PALM (formerly an abbreviation for Parallelized Large-eddy Simulation Model and now an independent name) is a Fortran-based code and has been applied for studying a ... -
Overview of the Rocket Experiment for NeutralUpwelling Sounding Rocket 2 (RENU2)
(Journal article; Peer reviewed, 2020)The Rocket Experiment for Neutral Upwelling 2 (RENU2) rocket was launched on 13 December 2015 at 07:34 UT. The payload transited the cusp region during a neutral upwelling event, supported by a comprehensive set of onboard ... -
An overview of the Upper Palaeozoic-Mesozoic stratigraphy of the NE Atlantic region
(Peer reviewed; Journal article, 2017)This study describes the distribution and stratigraphic range of the Upper Palaeozoic–Mesozoic succession in the NE Atlantic region, and is correlated between conjugate margins and along the axis of the NE Atlantic rift ... -
Oxidized Graphene on Ir(111): Wetting and Icephobic Properties Investigated on the Macroscopic and Atomic Scale
(Master thesis, 2020-08-09)Icing remains a huge challenge in a wide range of industries, from airplanes to optical sensors and wind turbines. Today's ice-combating approaches include thermal, mechanical, and chemical methods, which come with power, ... -
The oxygen requirement of Atlantic salmon (Salmo salar L.) in the on-growing phase in sea cages
(Doctoral thesis, 2012-10-30)Atlantic salmon aquaculture is a successful and growing industry, with a global production of more than 1.4 million tonnes in 2010. In the on-growing phase, Atlantic salmon are normally kept in sea cages, where both the ... -
Oxygen variation within a seacage
(Master thesis, 2008-06-01)In recent years, fish welfare during aquaculture production has received increasing attention, and it has been suggested that welfare is threatened as larger seacages are developed. Larger seacages with higher stocking ... -
Ozone-induced climate change propped up by the Southern Hemisphere oceanic front
(Peer reviewed; Journal article, 2015-11-23)The late twentieth century was marked by a significant summertime trend in the Southern Annular Mode (SAM), the dominant mode of tropospheric variability in the extratropical Southern Hemisphere (SH). This trend with ... -
Ötzi, 30 years on: A reappraisal of the depositional and post-depositional history of the find
(Journal article; Peer reviewed, 2023)When Ötzi, the Iceman, was found in a gully in the Tisenjoch pass in the Tyrolean Alps in 1991, he was a huge surprise for the archaeological community. The lead initial investigator of the find argued that it was unique, ... -
p-Kernel Stein Variational Gradient Descent for Data Assimilation and History Matching
(Journal article; Peer reviewed, 2021)A Bayesian method of inference known as “Stein variational gradient descent” was recently implemented for data assimilation problems, under the heading of “mapping particle filter”. In this manuscript, the algorithm is ... -
P3 problem and Magnolia language: Specializing array computations for emerging architectures
(Journal article; Peer reviewed, 2022)The problem of producing portable high-performance computing (HPC) software that is cheap to develop and maintain is called the P3 (performance, portability, productivity) problem. Good solutions to the P3 problem have ... -
Pacific and Atlantic Lepeophtheirus salmonis (Krøyer, 1838) are allopatric subspecies: Lepeophtheirus salmonis salmonis and L. salmonis oncorhynchi subspecies novo
(Peer reviewed; Journal article, 2014-03-14)Background: The salmon louse Lepeophtheirus salmonis is a parasitic copepod that infects salmonids in the Pacific and Atlantic oceans. Although considered as a single species, morphological and biological differences have ... -
Pacific circulation response to eastern Arctic sea ice reduction in seasonal forecast simulations
(Journal article; Peer reviewed, 2021)Recent studies point to the sensitivity of mid-latitude winter climate to Arctic sea ice variability. However, there remain contradictory results in terms of character and timing of Northern Hemisphere large-scale circulation ... -
Pacific contribution to decadal surface temperature trends in the Arctic during the twentieth century
(Journal article; Peer reviewed, 2021)Instrumental records suggest multidecadal variability in Arctic surface temperature throughout the twentieth century. This variability is caused by a combination of external forcing and internal variability, but their ... -
Pacific contribution to the early twentieth-century warming in the Arctic
(Journal article; Peer reviewed, 2018)Arctic surface temperature warmed more than twice as fast as global temperature during the early twentieth century, similar to that during the recent global warming. This Arctic warming has been attributed to both external ... -
Pacific oceanic front amplifies the impact of Atlantic oceanic front on North Atlantic blocking
(Journal article; Peer reviewed, 2023)Atmospheric blocking is a crucial driver of extreme weather events, but its climatological frequency is largely underestimated in state-of-the-art climate models, especially around the North Atlantic. While air-sea interaction ... -
Packing arc-disjoint cycles in tournaments
(Journal article; Peer reviewed, 2019)A tournament is a directed graph in which there is a single arc between every pair of distinct vertices. Given a tournament T on n vertices, we explore the classical and parameterized complexity of the problems of determining ... -
Packing cycles faster than Erdos-Posa
(Journal article; Peer reviewed, 2019)The Cycle Packing problem asks whether a given undirected graph $G=(V,E)$ contains $k$ vertex-disjoint cycles. Since the publication of the classic Erdös--Pósa theorem in 1965, this problem received significant attention ... -
PaCTS 1.0: a crowdsourced reporting standard for paleoclimate data
(Journal article; Peer reviewed, 2019-09)The progress of science is tied to the standardization of measurements, instruments, and data. This is especially true in the Big Data age, where analyzing large data volumes critically hinges on the data being standardized. ... -
Pairwise local Fisher and naive Bayes: Improving two standard discriminants
