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 ... -
Hydrogen production from fluctuating small-scale hydropower
(Master thesis, 2024-06-03)As the world seeks renewable alternatives to fossil fuels, hydrogen emerges as a valuable energy carrier to facilitate the green shift. When produced from renewable energy, hydrogen is considered a green fuel that can be ... -
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 ... -
Hyperheuristic Frameworks for Combinatorial Optimization Problems using Deep Reinforcement Learning
(Master thesis, 2024-06-17)Many metaheuristic frameworks exist for solving different combinatorial optimization problems. Despite formulating general strategies that can be applied to many problems, they often rely on problem-specific implementation. ... -
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 ... -
The ice front as a topographic barrier for ocean heat transport
(Doctoral thesis, 2021-06-28)Antarctic ice shelves are the link between the Southern Ocean and the Antarctic Ice Sheet. The floating ice shelves restrain the seaward flow of the grounded ice, which is balanced by iceberg calving and ocean-induced basal ... -
Ice shelf water overflow and bottom water formation in the southern Weddell Sea
(Peer reviewed; Journal article, 2004-02-17)Cold shelf waters flowing out of the Filchner Depression in the southern Weddell Sea make a significant contribution to the production of Weddell Sea Bottom Water (WSBW), a precursor to Antarctic Bottom Water (AABW). We ... -
The Iceland Greenland seas project
(Peer reviewed; Journal article, 2019)The Iceland Greenland Seas Project (IGP) is a coordinated atmosphere–ocean research program investigating climate processes in the source region of the densest waters of the Atlantic meridional overturning circulation. ... -
The Iceland-Faroe Slope Jet: a conduit for dense water toward the Faroe Bank Channel overflow
(Journal article; Peer reviewed, 2020)Dense water from the Nordic Seas passes through the Faroe Bank Channel and supplies the lower limb of the Atlantic Meridional Overturning Circulation, a critical component of the climate system. Yet, the upstream pathways ... -
The Iceland–Faroe inflow of Atlantic water to the Nordic Seas
(Peer reviewed; Journal article, 2003-12)The flow of Atlantic water between Iceland and the Faroe Islands is one of three current branches flowing from the Atlantic Ocean into the Nordic Seas across the Greenland–Scotland Ridge. By the heat that it carries along, ... -
Idealized Modeling of the North Icelandic Jet
(Master thesis, 2023-06-01)The North Icelandic Jet (NIJ) is a crucial component of the lower limb of the Atlantic Meridional Overturning Circulation, supplying one-third to one-half of the overflow water transport through Denmark Strait, including ...
