Warming beneath an East Antarctic ice shelf due to increased subpolar westerlies and reduced sea ice
(Journal article; Peer reviewed, 2023)Understanding how climate change influences ocean-driven melting of the Antarctic ice shelves is one of the greatest challenges for projecting future sea level rise. The East Antarctic ice shelf cavities host cold water ... -
Warming of Atlantic Water in two west Spitsbergen fjords over the last century (1912-2009)
(Peer reviewed; Journal article, 2013-05-06)The recently observed warming of west Spitsbergen fjords has led to anomalous sea-ice conditions and has implications for the marine ecosystem. We investigated long-term trends of maximum temperature of Atlantic Water (AW) ... -
Waste heat recovery for lunar applications of a solid oxide electrolyser
(Master thesis, 2023-12-20)In an effort to make space exploration more sustainable the space industry looks to In-Situ Resource Utilisation (ISRU) as a possible way to lower the cost. With confirmed findings of water ice on the south pole of Earth’s ... -
Water mass exchange, pathways and the mesoscale eddy field in the Lofoten Basin of the Norwegian Sea
(Doctoral thesis, 2020-11-05)The Lofoten Basin situated in the Norwegian Sea, plays a central role in redistributing and modifying the warm Atlantic Water carried poleward with the Norwegian Atlantic Current. Increased residence time of the warm ... -
Water mass modification in an Arctic fjord through cross-shelf exchange: The seasonal hydrography of Kongsfjorden, Svalbard
(Journal article, 2005-12-08)Kongsfjorden and the West Spitsbergen Shelf is a region whose seasonal hydrography is dominated by the balance of Atlantic Water, Arctic waters, and glacial melt. Regional seasonality and the cross-shelf exchange processes ... -
Water mass modification over the continental shelf north of Ronne Ice Shelf, Antarctica
(Journal article, 2003-08-13)We use new data from the southern Weddell Sea continental shelf to describe water mass conversion processes in a formation region for cold and dense precursors of Antarctic Bottom Water. The cruises took place in early ... -
Water mass transformation and the North Atlantic Current in three multi-century climate model simulations
(Journal article, 2012-11)The warm and saline Subtropical Water carried by the North Atlantic Current undergoes substantial transformation on its way to higher latitudes as heat is released from ocean to atmosphere. The geographical distribution ... -
Water mass transformation in the Greenland Sea during the period 1986-2016
(Peer reviewed; Journal article, 2019-01)Hydrographic measurements from ships, autonomous profiling floats, and instrumented seals over the period 1986–2016 are used to examine the temporal variability in open-ocean convection in the Greenland Sea during winter. ... -
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 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 ...
