High Voltage Laboratory Development: An in-depth Description and Report on the Process of Fabricating a Faraday Cage
(Master thesis, 2022-12-16)This thesis examines the quality of protection a Faraday cage provides against electromagnetic fields. The necessary theory to examine and calculate the shielding effectiveness of a Faraday cage, discuss obtained results ... -
High-frequency internal wave observations in the marginal ice zone
(Journal of Geophysical Research: Oceans;92(C7), Journal article, 1987-06-30) -
High-resolution stable isotope signature of a land-falling atmospheric river in southern Norway
(Journal article; Peer reviewed, 2021)Heavy precipitation at the west coast of Norway is often connected to elongated meridional structures of high integrated water vapour transport known as atmospheric rivers (ARs). Here we present high-resolution measurements ... -
A high‐resolution hindcast of wind and waves for the North Sea, the Norwegian Sea, and the Barents Sea
(Peer reviewed; Journal article, 2011-05)A combined high-resolution atmospheric downscaling and wave hindcast based on the ERA-40 reanalysis covering the Norwegian Sea, the North Sea, and the Barents Sea is presented. The period covered is from September 1957 to ... -
Historical and future runoff changes in the Yangtze River Basin from CMIP6 models constrained by a weighting strategy
(Journal article; Peer reviewed, 2022)Based on the ERA5-Land datasets from 1981–2020, a decadal oscillation has been found in the variation of summer runoff in the middle and lower reaches of the Yangtze River Basin (MLYRB). The oscillation suggests that the ... -
Holocene trends in the foraminifer record from the Norwegian Sea and the North Atlantic Ocean
(Peer reviewed; Journal article, 2010-03-30)The early to mid-Holocene thermal optimum is a well-known feature in a wide variety of paleoclimate archives from the Northern Hemisphere. Reconstructed summer temperature anomalies from across northern Europe show a clear ... -
How does latent cooling affect baroclinic development in an idealized framework?
(Peer reviewed; Journal article, 2019)Latent cooling by evaporating or melting hydrometeors has recently been shown to contribute to the positive low-level potential vorticity (PV) anomaly below the layer of latent heating in midlatitude cyclones. While the ... -
How Is the Ocean Anthropogenic Carbon Reservoir Filled?
(Journal article; Peer reviewed, 2022)About a quarter of the total anthropogenic CO2 emissions during the industrial era has been absorbed by the ocean. The rate limiting step for this uptake is the transport of the anthropogenic carbon (Cant) from the ocean ... -
How much arctic fresh water participates in the subpolar overturning circulation?
(Journal article; Peer reviewed, 2021)Fresh Arctic waters flowing into the Atlantic are thought to have two primary fates. They may be mixed into the deep ocean as part of the overturning circulation, or flow alongside regions of deep water formation without ... -
How northern freshwater input can stabilise thermohaline circulation
(Peer reviewed; Journal article, 2016)The North Atlantic thermohaline circulation (THC) carries heat and salt towards the Arctic. This circulation is partly sustained by buoyancy loss and is generally believed to be inhibited by northern freshwater input as ... -
How warm Gulf Stream water sustains a cold underwater waterfall
(Journal article, 2022)The most famous ocean current, the Gulf Stream, is part of a large system of currents that brings warm water from Florida to Europe. It is a main reason for northwestern Europe’s mild climate. What happens to the warm water ... -
Hvordan klimaet kan endres - en innføring
(Book, 2012-08-07)Denne boka handler om det naturvitenskapelige grunnlaget for klimaendringer, om hvordan klimaet kan endres, hva vi vet og hva som er usikkert. En stor del av arbeidet til FNs klimapanel IPCC omfatter dette grunnlaget, de ... -
Hydrogen Consumption by Halophilic Microorganisms - Implications for Underground Hydrogen Storage
(Master thesis, 2023-06-01)Underground Hydrogen Storage (UHS) in reservoirs and caverns is a possible solution for large-scale and long-term storage of hydrogen (H2) in the subsurface. As the cost of tech- nology installation and electricity from ... -
Hydrography and circulation in the Filchner Depression, Weddell Sea, Antarctica
(Peer reviewed; Journal article, 2014)Cold and dense ice shelf water (ISW) emerging from the Filchner-Ronne Ice Shelf cavity in the southwestern Weddell Sea flows northward through the Filchner Depression to eventually descend the con- tinental slope and ... -
Hydrography, circulation, and response to atmospheric forcing in the vicinity of the central Getz Ice Shelf, Amundsen Sea, Antarctica
(Journal article; Peer reviewed, 2022)Ice shelves in the Amundsen Sea are thinning rapidly as ocean currents bring warm water into the cavities beneath the floating ice. Although the reported melt rates for the Getz Ice Shelf are comparatively low for the ... -
Hydrography, transport and mixing of the West Spitsbergen Current: the Svalbard Branch in summer 2015
(Peer reviewed; Journal article, 2018-12-21)Measurements of ocean currents, stratification and microstructure were made in August 2015, northwest of Svalbard, downstream of the Atlantic inflow in Fram Strait in the Arctic Ocean. Observations in three sections are ... -
Hydrological Modelling of Ethiopian Watersheds : The Application of Hydrological Models for Flow Forecasting and Analysis of Sensitivity to Climate and Landuse Changes
(Doctoral thesis, 2019-10-15)Hydrological modelling studies vary depending on the purpose, data availability and number of outputs required. Quantifying the hydrological responses to various human- and climate-induced changes requires different modelling ... -
Hydropower Production Scheduling using Stochastisc Dual Dynamic Programming subject to environmental constraints
(Master thesis, 2019-06-22)Oppgaven utforsker vannkraftproduksjonsplanlegging i Bergsdalen vassdraget, styrt av BKK, ved hjelp av Stokastisk Dual Dynamisk Programmering. Systemet er under et sett med miljørestriksjoner, innført av NVE, som utfordrer ... -
Ice and brine production in Hornsund
(Master thesis, 2015-06-02)The Hornsund fjord system has been studied using observations of the atmosphere, ocean and sea ice, and two different types of models. The study documents significant year to year variability in sea ice formation and brine ...
