Technical note: Turbulence measurements from a light autonomous underwater vehicle
(Journal article; Peer reviewed, 2022)A self-contained turbulence instrument from Rockland Scientific was installed on a light autonomous underwater vehicle (AUV) from OceanScan Marine Systems and Technology Lda. We report on the data quality and discuss ... -
Temperature Inversions in the Bergen Valley and Testing of Low-Cost Temperature and Air Quality Measuring Instruments
(Master thesis, 2018-06-22)This study aimed at two goals, the testing of simple low-cost measurement sensors for temperature and air pollution, and the investigation of temperature inversions in the Bergen valley. For this we conducted a 13 months ... -
Temporal and spatial variability of the sea surface salinity in the Nordic Seas
(Peer reviewed; Journal article, 2002-11-02)In this paper, the temporal and spatial variability of the sea surface salinity (SSS) in the Nordic Seas is investigated. The data include a Russian hydrographical database for the Nordic Seas and daily to weekly observations ... -
Temporal biomass dynamics of an Arctic plankton bloom in response to increasing levels of atmospheric carbon dioxide
(Peer reviewed; Journal article, 2013-01-11)Ocean acidification and carbonation, driven by anthropogenic emissions of carbon dioxide (CO2), have been shown to affect a variety of marine organisms and are likely to change ecosystem functioning. High latitudes, ... -
Temporal variability in surface water pCO2 in Adventfjorden (West Spitsbergen) with emphasis on physical and biogeochemical drivers
(Peer reviewed; Journal article, 2018-07)Seasonal and interannual variability in surface water partial pressure of CO2 (pCO2) and air‐sea CO2 fluxes from a West Spitsbergen fjord (IsA Station, Adventfjorden) are presented, and the associated driving forces are ... -
Testing a Flexible Method to Reduce False Monsoon Onsets
(Peer reviewed; Journal article, 2014-08-08)To generate information about the monsoon onset and withdrawal we have to choose a monsoon definition and apply it to data. One problem that arises is that false monsoon onsets can hamper our analysis, which is often ... -
Thermodynamic controls of the Atlantic Niño
(Peer reviewed; Journal article, 2015-11-26)Prevailing theories on the equatorial Atlantic Niño are based on the dynamical interaction between atmosphere and ocean. However, dynamical coupled ocean-atmosphere models poorly simulate and predict equatorial Atlantic ... -
Thin and transient meltwater layers and false bottoms in the Arctic sea ice pack-Recent insights on these historically overlooked features
(Journal article; Peer reviewed, 2023)The rapid melt of snow and sea ice during the Arctic summer provides a significant source of low-salinity meltwater to the surface ocean on the local scale. The accumulation of this meltwater on, under, and around sea ice ... -
Thunderstorms in Norway. A climatological and a case study
(Master thesis, 2011-06-01)The object of this thesis are thunderstorms in Norway. In the first part, the variability of thunderstorms in time and space is investigated, based on synoptic observations from 60 weather stations in Norway. An analysis ... -
Tidal forcing, energetics, and mixing near the Yermak Plateau
(Peer reviewed; Journal article, 2015-03-27)The Yermak Plateau (YP), located northwest of Svalbard in Fram Strait, is the final passage for the inflow of warm Atlantic Water into the Arctic Ocean. The region is characterized by the largest barotropic tidal velocities ... -
Tidally Forced Lee Waves Drive Turbulent Mixing Along the Arctic Ocean Margins
(Journal article; Peer reviewed, 2020)In the Arctic Ocean, limited measurements indicate that the strongest mixing below the atmospherically forced surface mixed layer occurs where tidal currents are strong. However, mechanisms of energy conversion from tides ... -
Tidally induced internal motion in an Arctic fjord
(Peer reviewed; Journal article, 2014-01-10)The internal response in a stratified, partially enclosed basin subject to semi-diurnal tidal forcing through a narrow entrance is investigated. The site is located above the critical latitude where linear internal waves ... -
Tides and shallow water dynamics near Tromsø
(Master thesis, 2018-06-20)I have investigated the tidal dynamics near Tromsø using data from some observations and from a numerical model. These data show that currents relating to the shallow water tides are very pronounced at the Tromsøysund and ... -
Tides Structures and Mixing along the Mozambique Coast
(Master thesis, 2010-06-01)The resolution of environment problems suggests the study of tidal structures and mixing along the Mozambique Coast. Sofala Bank is the area with more available information for this study. Tides along the Mozambique Coast ... -
Tilpasning av elektronisk innsprøytningssystem, type Common Rail, for en én-sylindret dieseldrevet laboratoriemotor
(Master thesis, 2017-06-23)A modern diesel engine meets stringent demands in efficiency and emissions by adapting advanced technology. The technological advancements include the fuel injection system where advanced micro processing and fast actuators ... -
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. ...
