Water mass transformation in the Iceland Sea
(Peer reviewed; Journal article, 2015)The water mass transformation that takes place in the Iceland Sea during winter is investigated using historical hydrographic data and atmospheric reanalysis fields. Surface densities exceeding σθ ¼ 27:8 kg=m3, and hence ... -
Water mass transformation in the Iceland Sea: Contrasting two winters separated by four decades
(Journal article; Peer reviewed, 2022)Dense water masses formed in the Nordic Seas flow across the Greenland–Scotland Ridge and contribute substantially to the lower limb of the Atlantic Meridional Overturning Circulation. Originally considered an important ... -
Water mass transformations and air-sea exchange in the Barents Sea
(Doctoral thesis, 2011-09-22)Water mass transformation processes in the Barents Sea and their interannual to decadal variability are studied using a regional coupled ice-ocean model and observational data. Long-term data allows for assessment of ... -
Water mass transformations in the Barents Sea and linkages to the Polar Front
(Doctoral thesis, 2010-10-29) -
Waterside convection and stratification control methane spreading in supersaturated Arctic fjords (Spitsbergen)
(Journal article; Peer reviewed, 2021)Seasonally ice covered in the past, the fjords in West Spitsbergen turn into being perennially ice free in the present. This feedback to Arctic amplification of global warming changes gas fluxes at the atmosphere-ocean ... -
Wave and wind conditions in the Red Sea. A numerical study using a third generation wave model
(Master thesis, 2010-06-01)In order to understand how waves behave and how other parameters can interact between ocean and atmosphere we can use a numerical model. For the Red Sea basin wave measurements are absent and due to that a WAM wave model ... -
Wave energy potential in the area of Sulafjorden and Breisundet
(Master thesis, 2020-04-07) -
Wave Extremes in the Northeast Atlantic
(Peer reviewed; Journal article, 2012-03)The objective of this study is to compute 100-yr return value estimates of significant wave height using a new hindcast developed by the Norwegian Meteorological Institute. This regional hindcast covers the northeast ... -
Wave Measurements Using Ship Mounted Sensors as part of the One Ocean Expedition
(Master thesis, 2023-06-01)This thesis examines the design and post-processing aspects of wave measurements from ship mounted sensors. The wave measurements exhibit accuracy comparable to wave measuring drifters while offering enhanced spatial ... -
Wave runup estimates at gentle beaches in the northern Indian Ocean
(Master thesis, 2012-10-01)The aim of this study is to estimate the wave runup on selected beaches around the northern Indian Ocean. The runup has been estimated using ERA-Interim, which is the latest global atmospheric re-analysis produced by the ... -
Waveform classification of airborne synthetic aperture radar altimeter over Arctic sea ice
(Peer reviewed; Journal article, 2013-08-19)Sea ice thickness is one of the most sensitive variables in the Arctic climate system. In order to quantify changes in sea ice thickness, CryoSat-2 was launched in 2010 carrying a Ku-band radar altimeter (SIRAL) designed ... -
A wavelet-entropy based segmentation of turbulence measurements from a moored shear probe near the wavy sea surface
(Peer reviewed; Journal article, 2019-12-17)In this study, we explore the applicability of a wavelet-entropy based segmentation technique in reduction of motion-induced contaminations in time-domain from subsurface turbulence measurements made by a moving shear ... -
Wave–induced characteristics of atmospheric turbulence flux measurements
(Peer reviewed; Journal article, 2013)In this paper, we present the air–sea flux of momentum obtained with the eddy correlation method applied to data measured from a moored discus buoy deployed approximately 600 m off a research Air Sea Interaction Tower at ... -
Weakening Atlantic Niño-Pacific connection under greenhouse warming
(Peer reviewed; Journal article, 2019-08-21)Sea surface temperature variability in the equatorial eastern Atlantic, which is referred to as an Atlantic Niño (Niña) at its warm (cold) phase and peaks in boreal summer, dominates the interannual variability in the ... -
Weakening of Cold Halocline Layer Exposes Sea Ice to Oceanic Heat in the Eastern Arctic Ocean
(Journal article; Peer reviewed, 2020)A 15-yr duration record of mooring observations from the eastern (>70°E) Eurasian Basin (EB) of the Arctic Ocean is used to show and quantify the recently increased oceanic heat flux from intermediate-depth (~150–900 m) ... -
Weakening of the Atlantic Niño variability under global warming
(Journal article; Peer reviewed, 2022)The Atlantic Niño is one of the most important patterns of interannual tropical climate variability, but how climate change will influence this pattern is not well known due to large climate model biases. Here we show that ... -
Why has Precipitation Increased in the Last 120 Years in Norway?
(Journal article; Peer reviewed, 2022)We use a data set with daily precipitation observations from 55 homogeneity-tested stations in Norway from 1900 to 2019 available from MET-Norway. These observations show that precipitation in Norway has increased by 19% ... -
Wind and wave extremes over the world oceans from very large ensembles
(Peer reviewed; Journal article, 2014-07)Global return values of marine wind speed and significant wave height are estimated from very large aggregates of archived ensemble forecasts at +240 h lead time. Long lead time ensures that the forecasts represent independent ... -
Wind coherence measurement by a single pulsed Doppler wind lidar
(Peer reviewed; Journal article, 2016-09)A single pulsed Doppler wind lidar, deployed at the FINO1 platform in the North Sea, has been used to monitor the lateral and vertical coherence of the along-wind component. To maximize the sampling frequency of the ... -
Wind Farm Layout Optimization - A case study on maximizing the annual energy production in Creyke Beck B.
(Master thesis, 2016-06-01)For offshore wind farms, detailed planning, including wind farm design optimization, is becoming increasingly important to secure and increase the wind farm's revenue during its operational life time. Since the energy ...
