Sea ice velocity in the Fram Strait monitored by moored instruments
(Peer reviewed; Journal article, 2003-10-04)The Fram Strait sea ice velocity was measured by means of a new method using moored Doppler Current Meters in the period 1996–2000. Almost 3 years of ice velocity observations near 79N 5W are analyzed. The average southward ... -
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, ... -
On the nature of the factors that control spring bloom development at the entrance to the Barents Sea and their interannual variability
(Journal article, 2003-12)Analysis of data obtained by the Institute of Marine Research, Norway, at their regular surveys of the Fugløya-Bjørnøya section, between the northern tip of Norway and Bear Island, has allowed for an identification of the ... -

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 ... -
Simulating transport of non-Chernobyl 137Cs and 90Sr in the North Atlantic–Arctic region
(Peer reviewed; Journal article, 2004)The spatial and temporal distributions of the anthropogenic radionuclides 137Cs and 90Sr, originating from nuclear bomb testing and the Sellafield reprocessing plants in the Irish Sea, are simulated using a global version ... -
Effects of solar irradiance forcing on the ocean circulation and sea-ice in the North Atlantic in an isopycnic coordinate ocean general circulation model
(Peer reviewed; Journal article, 2004)The sensitivity of the ocean circulation to changes in solar irradiance is examined using an isopycnic coordinate, global ocean general circulation model (OGCM) coupled to a thermodynamic/dynamic sea-ice model. In the ... -
Single CO2 drops in seawater
(Master thesis, 2004)To mitigate the increasing atmospheric CO2 level and reduce the subsequent impacts, storage of CO2 is one option that might become necessary. Ocean storage and storage of CO2 under the sea bottom with potential leakage ... -
Mass balance of Nyainqen Tanglha glacier, Tibet, 1977 to 2001, derived by topographical maps and satellite images
(Master thesis, 2004)NyainQen TangLha Glacier plays an important role in the Tibetan plateau’s climate system. Because of high altitude, steeply sloping terrain and difficult access, regular, systematic surveys of glacial variation are almost ... -
The East Greenland Current: Structure and Variability
(Master thesis, 2004) -
Benguela Niños: Observations and Modelling
(Master thesis, 2004)A numerical ocean model for the South Atlantic was used to study the 1995 Benguela Niño in order to learn about the underlying forcing mechanisms of the phenomenon. By comparing observations and model output, it was found ... -
Polar low le Cygne: Satellite observations and numerical simulations
(Journal article, 2004)A polar low (PL) which occurred in October 1993 over the Norwegian Sea is investigated from an observational and a numerical point of view. This PL has several unique features: it developed early in the season, it lasted ... -
Simulated Mass, Heat and Freshwater Budgets of the Artic Mediterranean - Present and Future
(Master thesis, 2004)The majority of recent climate forecast studies suggest a dramatic thinning of the Arctic multi year ice and eventually the disappearing of all summer ice within just a few decades. Moreover, in the maritime Arctic a large ... -
On the recent time history and forcing of the inflow of Atlantic Water to the Arctic Mediterranean
(Extended Abstract for The ACIA International Scientific Symposium on Climate Change in the Arctic, Conference lecture, 2004) -
Mixing of the Storfjorden overflow (Svalbard Archipelago) inferred from denstity overturns
(Journal article, 2004-01-03)Observations were made of the dense overflow from Storfjorden from a survey conducted at closely spaced stations in August 2002. The field data set consists of conventional conductivity-temperature-depth profiles and ... -
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 ... -
Monthly to annual variability of the Norwegian Atlantic slope current: connection between the northern North Atlantic and the Norwegian Sea
(Peer reviewed; Journal article, 2004-03)This study investigated relations between direct current measurements in the Norwegian Atlantic slope current (NwASC), the sea surface height variability from the TOPEX altimeter, and reanalysed mean sea level pressure ... -
Effects of solar irradiance forcing on the ocean circulation and sea-ice in the North Atlantic in an isopycnic coordinate ocean general circulation model
(Tellus;56A(2), Journal article, 2004-03)The sensitivity of the ocean circulation to changes in solar irradiance is examined using an isopycnic coordinate, global ocean general circulation model (OGCM) coupled to a thermodynamic/dynamic sea-ice model. In the ... -
The Effect of Diapycnal Mixing on the Ventilation and CFC-11 Uptake in the Southern Ocean
(Advances in Atmospheric Sciences;21(5), Journal article, 2004-03-04)The Miami Isopycnic Coordinate Ocean Model (MICOM) is used to investigate the effect of diapycnal mixing on the oceanic uptake of CFC-11 and the ventilation of the surface waters in the Southern Ocean (south of 45°S). Three ... -
A Possible Feedback Mechanism Involving the Arctic Freshwater, the Arctic Sea Ice, and the North Atlantic Drift
(Advances in Atmospheric Sciences;21( 5), Journal article, 2004-03-15)Model studies point to enhanced warming and to increased freshwater fluxes to high northern latitudes in response to global warming. In order to address possible feedbacks in the ice-ocean system in response to such changes, ...
