Dynamics of a CO2-seawater interface in the deep ocean
(Journal article, 2005)A trough filled with liquid CO2 located at 3940 m depth has been used as a model system for CO2 deposition on the seafloor. To study the intrinsic properties of the interface between CO2 and seawater a wave maker was used ... -
The dynamics of a metapopulation: Changes in life-history traits in resident herring that co-occur with oceanic herring during spawning
(Peer reviewed; Journal article, 2014-07-22)Different populations of Atlantic herring are regarded as forming a metapopulation, but we know little about the dynamics of the connectivity and degree of interbreeding between the populations. Based on data from three ... -
Dynamics of anomalous stratospheric eddy heat flux events in an idealized model
(Journal article; Peer reviewed, 2020-05-28)Extreme stratospheric eddy and sudden stratospheric warming (SSW) events both involve anomalous stratospheric eddy heat flux. The cause of the anomaly has been hypothesized to be due to tropospheric or stratospheric dynamics. ... -
The dynamics of Chironomidae (Insecta: Diptera) assemblages in response to environmental change during the past 700 years on Svalbard
(Peer reviewed; Journal article, 2004)The impact of recent natural and human-induced environmental change on chironomid faunas on Svalbard has been investigated. The modern chironomid fauna was studied from surface-sediment samples collected from 23 lakes in ... -
Dynamics of concurrent and sequential Central European and Scandinavian heatwaves
(Journal article; Peer reviewed, 2020)In both 2003 and 2018 a heatwave in Scandinavia in July was followed by a heatwave in Central Europe in August. Whereas the transition occurred abruptly in 2003, it was gradual in 2018 with a 12-day period of concurrent ... -
Dynamics of excited atoms and molecules interacting with external fields
(Doctoral thesis, 2013-08-30)This thesis is a theoretical study of the behavior of electrons in atoms and molecules subjected to external electromagnetic fields. Three electronic systems have been central in this work, the atomic and quasimolecular ... -
Dynamics of spawning migrations in Northeast Arctic cod
(Doctoral thesis, 2010-12-10)The Northeast Arctic (NA) cod is known to undertake long southbound spawning migrations from their feeding grounds in the Barents Sea, to various spawning grounds along the Norwegian coast. Hence it’s native Norwegian name ... -
Dynamics of Spontaneous (Multi) Centennial‐Scale Variations of the Atlantic Meridional Overturning Circulation Strength During the Last Interglacial
(Journal article; Peer reviewed, 2020)Recent reconstructions of bottom water δ13C during the last interglacial (LIG) suggest short-lived variability in the Atlantic meridional overturning circulation (AMOC). Spontaneous (multi) centennial-scale variability of ... -
Dynamics of the Barents Sea pelagic compartment: species distributions, interactions and response to climate variability
(Doctoral thesis, 2017-01-20)Long, consistent and uninterrupted monitoring resulting in time series of biological and environmental data are needed to understand the relations between environment and species, and species interactions, which also affect ... -
The Dynamics of the East Madagascar Current System and Its Influence on the Biological Production Associated to the Shelf - An Observational Study
(Master thesis, 2011-06-01)The dynamics of the East Madagascar Current (EMC) system, and its influence on the biological production associated to the shelf, is studied by using cruise-data collected onboard the Norwegian R/V. Dr. Fridtjof Nansen ... -
Dynamics of the Northeast Greenland Ice Stream: the role of geothermal heat and subglacial hydrology
(Doctoral thesis, 2019-11-15)Ice streams are rivers of fast flowing ice, crucial for the mass balance of ice sheets. The Greenland Ice Sheet shows a complex flow pattern, where a few major ice streams drain most of the ice sheet, contributing to sea ... -
Dynamics of the seasonal floodplain fishery of the Okavango Delta, Botswana
(Doctoral thesis, 2019-08-28)Inland fisheries provide vital proteins, jobs and income, for some of the most marginalized communities of the world. The role of inland fisheries in household food security is particularly important in Africa, where most ... -
The dynamics of trait variance in multi-species communities: Multi-species trait variance dynamics
(Journal article; Peer reviewed, 2020)In this paper, we establish the explicit connection between deterministic trait-based population-level models (in the form of partial differential equations) and species-level models (in the form of ordinary differential ... -
Dynamics-function relationship in the catalytic domains of N-terminal acetyltransferases
(Journal article; Peer reviewed, 2020)N-terminal acetyltransferases (NATs) belong to the superfamily of acetyltransferases. They are enzymes catalysing the transfer of an acetyl group from acetyl coenzyme A to the N-terminus of polypeptide chains. N-terminal ... -
Earlier hatching and slower growth: a key to survival in the early life history of Norwegian spring spawning herring
(Peer reviewed; Journal article, 2018-10-02)Faster growth in fish larvae is often associated with enhanced survival, and here we investigated whether surviving juvenile Norwegian spring spawning herring Clupea harengus L. generally come from a pool of fast-growing ... -
Earlier sea-ice melt extends the oligotrophic summer period in the Barents Sea with low algal biomass and associated low vertical flux
(Journal article; Peer reviewed, 2023)The decrease in Arctic sea-ice extent and thickness as a result of global warming will impact the timing, duration, magnitude and composition of phytoplankton production with cascading effects on Arctic marine food-webs ... -
Early detection of anthropogenic climate change signals in the ocean interior
(Journal article; Peer reviewed, 2023)Robust detection of anthropogenic climate change is crucial to: (i) improve our understanding of Earth system responses to external forcing, (ii) reduce uncertainty in future climate projections, and (iii) develop efficient ... -
Early detection of medical deterioration of patients with diabetes by using machine learning
(Master thesis, 2020-06-27)Diabetes is a growing healthcare problem in the world, which affects over 400 million adults. In collaboration with Haukeland University Hospital, we look at medical records from real patients diagnosed with diabetes. The ... -
Early Holocene Temperature Oscillations Exceed Amplitude of Observed and Projected Warming in Svalbard Lakes
(Journal article; Peer reviewed, 2019)Arctic climate is uniquely sensitive to ongoing warming. The feedbacks that drive this amplified response remain insufficiently quantified and misrepresented in model scenarios of future warming. Comparison with paleotemperature ...
