Water level fluctuations and the ecosystem functioning of lakes
(Peer reviewed; Journal article, 2018-08-28)Hydrological regimes are key drivers of productivity and structure in freshwater ecosystems but are increasingly impacted by human activity. Using 17 published food web models of 13 African lakes as a case study, we explored ... -
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) -
Water masses constrain the distribution of deep-sea sponges in the North Atlantic Ocean and Nordic Seas
(Journal article; Peer reviewed, 2021)Water masses are bodies of water with distinctive physical and biogeochemical properties. They impart vertical structure to the deep ocean, participate in circulation, and can be traced over great distances, potentially ... -
Water Migration in the Subduction Mantle Wedge: A Two-Phase Flow Approach
(Journal article; Peer reviewed, 2019)Subduction zones are the main entry points of water into Earth's mantle and play an important role in the global water cycle. The progressive release of water by metamorphic dehydration induces important physical‐chemical ... -
Water renewal in a threshold fjord: A simulation study of submerged fresh water discharge
(Master thesis, 2018-12-15)Threshold fjords are characterized by low concentrations of oxygen in the depths of the basin, caused by weak and/or infrequent exchange of the basin water. A three-dimensional ocean model, The Bergen Ocean Model (BOM), ... -
Water shutoff and conformance improvement: an introduction
(Journal article; Peer reviewed, 2021)This paper provides an introduction to the topic of water shutoff and conformance improvement. After indicating the volumes of water produced during oilfield operations, a strategy is provided for attacking excess water ... -
Water temperature and dietary histidine affect cataract formation in Atlantic salmon (Salmo salar L.) diploid and triploid yearling smolt
(Peer reviewed; Journal article, 2017-09)The aim of the present study was to investigate cataract development in diploid (2N) and triploid (3N) Atlantic salmon smolts and post-smolts at two water temperatures (10 and 16 °C) given diets with different histidine ... -
Water-Accelerated Decomposition of Olefin Metathesis Catalysts
(Journal article; Peer reviewed, 2023)Water is ubiquitous in olefin metathesis, at levels ranging from contaminant to cosolvent. It is also non-benign. Water-promoted catalyst decomposition competes with metathesis, even for “robust” ruthenium catalysts. ... -
Waterflood Efficiency and Single-Phase Flow Properties of Carbonate Porous Media
(Doctoral thesis, 2009-12-17) -
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 ...
