Time Scales and Sources of European Temperature Variability
(Peer reviewed; Journal article, 2018-04)Skillful predictions of continental climate would be of great practical benefit for society and stakeholders. It nevertheless remains fundamentally unresolved to what extent climate is predictable, for what features, at ... -
A toolbox for secondary quality control on ocean chemistry and hydrographic data
(Peer reviewed; Journal article, 2015-11)High quality, reference measurements of chemical and physical properties of seawater are of great importance for a wide research community, including the need to validate models and attempts to quantify spatial and temporal ... -
Topographic effects on CO2, diffusion and dissolution from the seafloor
(Peer reviewed; Journal article, 2009-02)At 3000 meters depth liquid CO2 is denser than seawater and hence will be stored as a “lake” on the deep ocean floor, which is expected to gradually be dissolved in seawater. Ocean currents and turbulence will influence ... -
Topographic Effects on Strong Winds in Southern Norway; A Case Study of the Storm Dagmar
(Master thesis, 2014-06-02)During the 25th of December 2011 a strong low pressure system struck Soutwestern Norway. This rapidly evolving system got the name "Dagmar". The aim of this thesis was to find out how the complex topography in Southern ... -
Topographically Controlled Flow in the Isfjorden Trough and the West Spitsbergen Shelf
(Master thesis, 2011-11-20)A one layer numerical model demonstrates how the Atlantic Water (AW) from the West Spitsbergen Current (WSC) is topographically steered onto the West Spitsbergen Shelf (WSS) with a special emphasise on the Isfjorden Trough. ... -
Toward a Comprehensive and Integrated Strategy of the European Marine Research Infrastructures for Ocean Observations
(Journal article; Peer reviewed, 2020)Research Infrastructures (RIs) are large-scale facilities encompassing instruments, resources, data and services used by the scientific community to conduct high-level research in their respective fields. The development ... -
Toward an ice-free Barents Sea
(Peer reviewed; Journal article, 2017)Arctic winter sea ice loss is most pronounced in the Barents Sea. Here we combine observations since 1850 with climate model simulations to examine the recent record low winter Barents Sea ice extent. We find that the ... -
Towards a better representation of fog microphysics in large-eddy simulations based on an embedded Lagrangian cloud model
(Journal article; Peer reviewed, 2020)The development of radiation fog is influenced by multiple physical processes such as radiative cooling and heating, turbulent mixing, and microphysics, which interact on different spatial and temporal scales with one ... -
Towards a more saline North Atlantic and a fresher Arctic under global warming
(Peer reviewed; Journal article, 2006-11-14)Most atmosphere-ocean general circulation models (GCMs) forced with increasing greenhouse gas concentrations predict enhanced atmospheric moisture transports to the high northern latitudes. Together with melting of Arctic ... -
Towards end-to-end (E2E) modelling in a consistent NPZD-F modelling framework (ECOSMO E2E_v1.0): Application to the North Sea and Baltic Sea
(Peer reviewed; Journal article, 2019-05-06)Coupled physical–biological models usually resolve only parts of the trophic food chain; hence, they run the risk of neglecting relevant ecosystem processes. Additionally, this imposes a closure term problem at the respective ... -
Towards quantifying the increasing role of oceanic heat in sea ice loss in the new Arctic
(Peer reviewed; Journal article, 2015)The loss of Arctic sea ice has emerged as a leading signal of global warming. This, together with acknowledged impacts on other components of the Earth system, has led to the term “the new Arctic.” Global coupled climate ... -
Towards Retrieving Reliable Ocean Surface Currents in the Coastal Zone From the Sentinel-1 Doppler Shift Observations
(Journal article; Peer reviewed, 2022)Recent developments on calibration and partitioning of the signal between the wave and current contributions significantly improve the accuracy of geophysical retrievals from Sentinel-1 Synthetic Aperture Radar-based Doppler ... -
Tracer-derived transit time of the waters in the eastern Nordic Seas
(Peer reviewed; Journal article, 2005-08-25)The spatial-temporal distribution of the anthropogenic radionuclide 137Cs originating from nuclear bomb testing and the Sellafield reprocessing plant in the Irish Sea is simulated using a global version of the Miami Isopycnic ... -
Tracing Lower Cretaceous organic-rich units across the SW Barents Shelf
(Journal article; Peer reviewed, 2022)On the Barents Shelf, the northernmost and least explored hydrocarbon province of the Norwegian Continental Shelf, Upper Jurassic organic-rich shales have traditionally been given most attention as these represent the most ... -
Tracing the Imprint of River Runoff Variability on Arctic Water Mass Transformation
(Peer reviewed; Journal article, 2019-01-14)The Arctic Ocean receives a net freshwater input from land and from the atmosphere. This flux of freshwater, along with net surface heat loss, acts to transform the water mass properties of inflowing Atlantic and Pacific ... -
Tracking Summer Extra-Tropical Storms: A Climatological Overview and Variability in the Northern Hemisphere

Training a supermodel with noisy and sparse observations: A case study with CPT and the synch rule on SPEEDO-v.1
(Journal article; Peer reviewed, 2022)As an alternative to using the standard multi-model ensemble (MME) approach to combine the output of different models to improve prediction skill, models can also be combined dynamically to form a so-called supermodel. The ... -
Training of supermodels - in the context of weather and climate forecasting
(Doctoral thesis, 2021-02-08)Given a set of imperfect weather or climate models, predictions can be improved by combining the models dynamically into a so called `supermodel'. The models are optimally combined to compensate their individual errors. ... -
Transient response of the Atlantic Meridional Overturning Circulation to enhanced freshwater input to the Nordic Seas–Arctic Ocean in the Bergen Climate Model
(Tellus A;56(4), Journal article, 2004-07-09)The transient response of the climate system to anomalously large freshwater input to the high latitude seas is examined using the newly developed Bergen Climate Model. A 150-yr twin-experiment has been carried out, ... -
Transientstabilitet-implementering ved BESS for offshore mikronett i øymodus
(Master thesis, 2022-06-01)Konvensjonelle mikronett har tradisjonelt sikret spenning- og frekvensstabilitet med spinning-reserve fra roterende maskiner ved forstyrrelser i nettet. En økende andel av ikke-roterende energiproduksjon påvirker kraftsystemers ...
