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 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 open source ship mounted ultrasonic altimeter and motion correction system during the one ocean circumnavigation
(Journal article; Peer reviewed, 2024)This study reviews the design and signal processing of ship borne ultrasonic altimeter wave measurements. The system combines a downward facing ultrasonic altimeter to capture the sea surface elevation as a time series, ... -
Wave modulation by strong currents: A study in the Lofoten Maelstrom and surrounding areas
(Doctoral thesis, 2024-06-07)Bølger og strøm – allestedsnærværende trekk ved havet – er i en konstant tilstand av gjensidig vekselvirkning. Disse prosessene forårsaker sterkt inhomogene sjøtilstander. Samspillet dem imellom regulerer utvekslingsprosesser ... -
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 ... -
WCD Ideas: Teleconnections through weather rather than stationary waves
(Journal article; Peer reviewed, 2024)Conventionally, teleconnections in the atmosphere are described by correlations between monthly mean fields. These correlations are supposedly caused by stationary Rossby waves. The main hypothesis explored in this idea ... -
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 ... -
Wind Intensity Is Key to Phytoplankton Spring Bloom Under Climate Change
(Peer reviewed; Journal article, 2019-08-30)The onset of the spring bloom (OSB) occurs when phytoplankton growth exceeds losses and is promoted by a transition from deep convection to a shallow mixing layer concurrent with increasing light intensities in nutrient-enriched ... -
Wind Stress in the Coastal Zone: Observations from a Buoy in Southwestern Norway
(Peer reviewed; Journal article, 2019-08-26)Several studies have focused on the investigation of the wind stress in open ocean conditions where coastal processes were negligible. However, the direction and magnitude of the wind stress vector in coastal areas are ...
