Annual cycles of sea level and sea surface temperature in the western Mediterranean Sea
(Peer reviewed; Journal article, 2003-03-01)In the western Mediterranean Sea, sea level variations are the result of seasonal steric effect, atmospheric forcing and mesoscale circulation activity, particularly in the Alboran and Algerian basins, as well as water ... -
Anthropogenic increase of oceanic pCO2 in the Barents Sea surface water
(Peer reviewed; Journal article, 2003-12-26)We evaluate the change of surface water CO2 partial pressure ( pCO2 sw) in the Barents Sea (BS) between 1967 and 2000–2001. We use temperature (T) data collected during a survey in the BS in 1967 and a relationship between ... -
Application of the unmanned Offshore Sensing SailBuoy for validation of ocean model simulations and remote sensing data in the North Atlantic
(Master thesis, 2015-12-01)The Offshore Sensing SailBuoy, is a remotely controlled, wind driven unmanned ocean vehicle. It sampled near surface properties during a mission in the North Atlantic in June - August 2014. Three parameters were recorded, ... -
Aragonite saturation states and pH in western Norwegian fjords: Seasonal cycles and controlling factors, 2005-2009
(Peer reviewed; Journal article, 2016-07-26)The uptake of anthropogenic carbon dioxide (CO2) by the ocean leads to a process known as ocean acidification (OA), which lowers the aragonite saturation state (ΩAr) and pH, and this is poorly documented in coastal ... -
Arctic amplification under global warming of 1.5 and 2 °C in NorESM1-Happi
(Peer reviewed; Journal article, 2019)Differences between a 1.5 and 2.0 ∘C warmer climate than 1850 pre-industrial conditions are investigated using a suite of uncoupled (Atmospheric Model Intercomparison Project; AMIP), fully coupled, and slab-ocean experiments ... -
Arctic climate change: observed and modelled temperature and sea-ice variability
(Tellus A 56A(4), Peer reviewed; Journal article, 2004-07-09)Changes apparent in the arctic climate system in recent years require evaluation in a century-scale perspective in order to assess the Arctic's response to increasing anthropogenic greenhouse-gas forcing. Here, a new set ... -
The Arctic Fjord Breeze: Characteristics of a Combined Sea Breeze and Valley Wind in a Svalbard Fjord Valley
(Journal article; Peer reviewed, 2023)Thermally-driven circulations are a frequent meteorological phenomenon in complex Arctic terrain, but the Arctic fjord breeze, a combined sea-breeze and up-valley wind, has received little attention. A field campaign was ... -
Arctic freshwater fluxes: sources, tracer budgets and inconsistencies
(Peer reviewed; Journal article, 2019)The net rate of freshwater input to the Arctic Ocean has been calculated in the past by two methods: directly, as the sum of precipitation, evaporation and runoff, an approach hindered by sparsity of measurements, and by ... -
Arctic Ocean Amplification in a warming climate in CMIP6 models
(Journal article; Peer reviewed, 2022)Arctic near-surface air temperature warms much faster than the global average, a phenomenon known as Arctic Amplification. The change of the underlying Arctic Ocean could influence climate through its interaction with sea ... -
Arctic Ocean carbon biogeochemistry under climate change and ocean acidification
(Doctoral thesis, 2013-05-10)Human-induced CO2 emissions to the atmosphere cause climate change and ocean acidification. The strongest indicators of climate change and ocean acidification are expected to be found in the Arctic Ocean (AO). The AO area ... -
Arctic Ocean CO2 uptake: An improved multiyear estimate of the air-sea CO2 flux incorporating chlorophyll a concentrations
(Peer reviewed; Journal article, 2018-03-22)We estimated monthly air–sea CO2 fluxes in the Arctic Ocean and its adjacent seas north of 60∘ N from 1997 to 2014. This was done by mapping partial pressure of CO2 in the surface water (pCO2w) using a self-organizing map ... -
The Arctic Ocean in a Fresh and Warm Future
(Doctoral thesis, 2016-10-28)The Arctic Ocean remains one of the least known ocean regions due to its remote location, year-round sea ice cover, and harsh weather conditions. Today, knowledge of the Arctic atmosphere-sea ice-ocean system increases in ... -
Arctic Ocean Response to Greenland Sea Wind Anomaliesin a Suite of Model Simulations
(Peer reviewed; Journal article, 2019-08-04)Plain Language Summary: The North Atlantic Current is an extension of the Gulf Stream, which brings warm Atlantic Water northward as the current flows through the Nordic Seas. Eventually, it enters the cold deep Arctic ... -
The Arctic Sea Ice - Melting During Summer or not Freezing in Winter?
(Master thesis, 2016-06-01)The Arctic sea ice cover has retreated rapidly during the last three decades, concurrent with recent global temperature increase both in the atmosphere and in the ocean. The sea ice cover has experienced a retreat in extent ... -
Arctic sea ice altimetry - advances and current uncertainties
(Doctoral thesis, 2014-06-11)One of the most prominent features of global climate change is the reduction in Arctic sea ice thickness. The main tool to derive sea ice thickness on an Arctic wide scale is altimetry from satellites, yet current estimates ... -
Arctic sea ice and climate change - will the sea ice disappear in this century?

Arctic sea ice and Eurasian climate: A review
(Peer reviewed; Journal article, 2014-11-28)The Arctic plays a fundamental role in the climate system and has shown significant climate change in recent decades, including the Arctic warming and decline of Arctic sea-ice extent and thickness. In contrast to the ... -
The Arctic sea ice extent change connected to Pacific decadal variability
(Journal article; Peer reviewed, 2020)After an unprecedented retreat, the total Arctic sea ice cover for the post-2007 period is characterized by low extent and a remarkable increase in annual cycle amplitude. We have identified the leading role of spring ... -
