High-latitude magnetic fields and their time derivatives: interhemispheric similarities
(Peer reviewed; Journal article, 2013-02-19)There are two simple and objective measures of geomagnetic activity: the daily range of field components, and the daily maximum of the time derivative of the field. We study these using data from the geomagnetic latitude ... -
High-order harmonic generation from graphene: Strong attosecond pulses with arbitrary polarization
(Peer reviewed; Journal article, 2013-05-03)We explore high-order harmonic generation (HHG) from a graphene sheet exposed to intense femtosecond laser pulses based on the Lewenstein model. It is demonstrated that the HHG cutoff frequency increases with graphene size ... -
High-performance design patterns for modern Fortran
(Peer reviewed; Journal article, 2015)This paper presents ideas for using coordinate-free numerics in modern Fortran to achieve code flexibility in the partial differential equation (PDE) domain. We also show how Fortran, over the last few decades, has changed ... -
High-precision limits on W–W′and Z–Z′ mixing from diboson production using the full LHC Run 2 ATLAS data set
(Journal article; Peer reviewed, 2020)The full ATLAS Run 2 data set with time-integrated luminosity of 139fb−1 in the diboson channels in hadronic final states is used to probe a simple model with an extended gauge sector (EGM), proposed by Altarelli et al., ... -
High-quality draft genome of the methanotroph Methylovulum psychrotolerans Str. HV10-M2 isolated from plant material at a high-altitude environment
(Peer reviewed; Journal article, 2018-04-12)Here we present the genome of Methylovulum psychrotolerans strain HV10-M2, a methanotroph isolated from Hardangervidda national park (Norway). This strain represents the second of the two validly published species genus ... -
High-Resolution Environmagnetic Study of HOTRAX Core JPC-14 from the Alpha Ridge, Arctic Ocean
(Master thesis, 2007-11-19)Core JPC-14 was derived from the HLY-0503 expedition from the Alpha Ridge. My supervisor professor Reidar Løvlie guided me with the project, from experiments, data obtaining, and analyisis. -
High-Resolution Mapping of Forest Structure From SAR and Optical Satellite Imagery Using Deep Learning

High-Resolution Ps Receiver Function Imaging of the Crust and Mantle Lithosphere Beneath Southern New England and Tectonic Implications
(Journal article; Peer reviewed, 2021)Southern New England exhibits diverse geologic features resulting from past tectonic events. These include Proterozoic and early Paleozoic Laurentian units in the west, several Gondwana-derived terranes that accreted during ... -
High-resolution record revealsclimate-driven environmental andsedimentary changes in an active rift
(Peer reviewed; Journal article, 2019-02-28)Young rifts are shaped by combined tectonic and surface processes and climate, yet few records exist to evaluate the interplay of these processes over an extended period of early rift-basin development. Here, we present ... -
High-resolution stable isotope signature of a land-falling atmospheric river in southern Norway
(Journal article; Peer reviewed, 2021)Heavy precipitation at the west coast of Norway is often connected to elongated meridional structures of high integrated water vapour transport known as atmospheric rivers (ARs). Here we present high-resolution measurements ... -
A high-resolution study of Holocene paleoclimatic and paleoceanographic changes in the Nordic Seas
(Peer reviewed; Journal article, 2003-03-26)High-resolution records from IMAGES core MD95-2011 in the eastern Norwegian Sea provide evidence for relatively large- and small-scale high-latitude climate variability throughout the Holocene. During the early and ... -
High-resolution δ^18 O and assemblage analysis between 1949- and 2000 AD based on planktonic foraminifera from the Storegga Slide, eastern Norwegian Sea
(Master thesis, 2016-09-28)In this study are presented results from a high-resolution δ^18 O and assemblage analysis between 1949- and 2000 AD based on planktonic foraminifera from core GS13-182-01. The core was retrieved from the head of the Storegga ... -

High-throughput metabarcoding of eukaryotic diversity for environmental monitoring of offshore oil-drilling activities
(Peer reviewed; Journal article, 2016-09)As global exploitation of available resources increases, operations extend towards sensitive and previously protected ecosystems. It is important to monitor such areas in order to detect, understand and remediate environmental ... -
High-value fatty acids from microalgae. Bioprospecting and outdoor cultivation at northern latitudes
(Doctoral thesis, 2018-05-11)Achieving a sustainable and cost-efficient production is imperative to establish microalgae as a new feedstock for aquaculture, where they can potentially replace the use of fish oil from wild catch as a source for the ... -
