Disentangling the impact of air-sea interaction and boundary layer cloud formation on stable water isotope signals in the warm sector of a Southern Ocean cyclone
(Journal article; Peer reviewed, 2022)Stable water isotopes in marine boundary layer water vapour are strongly influenced by the strength of air–sea fluxes. Air–sea fluxes in the extratropics are modulated by the large-scale atmospheric flow, for instance by ... -
Disentangling the impact of Atlantic Niño on sea-air CO2 flux
(Journal article; Peer reviewed, 2023)Atlantic Niño is a major tropical interannual climate variability mode of the sea surface temperature (SST) that occurs during boreal summer and shares many similarities with the tropical Pacific El Niño. Although the ... -
Dispersion and abundance of salmon lice (Lepeophtheirus salmonis) in a Norwegian fjord system
(Master thesis, 2011-11-20)Based on numerical results of currents from a high resolution fjord model, dispersion of salmon lice (Lepeophtheirus salmonis) in the Hardangerfjord has been modelled. The results show that salmon lice abundance in the ... -
Dissipation measurements using temperature microstructure from an underwater glider
(Peer reviewed; Journal article, 2014-09)Microstructure measurements of temperature and current shear are made using an autonomous underwater glider. The glider is equipped with fast-response thermistors and airfoil shear probes, providing measurements of dissipation ... -
The dissipation of kinetic energy in the Lofoten Basin Eddy
(Peer reviewed; Journal article, 2018-06)Ocean microstructure, current, and hydrography observations from June 2016 are used to characterize the turbulence structure of the Lofoten Basin eddy (LBE), a long-lived anticyclone in the Norwegian Sea. The LBE had an ... -
Dissipation of turbulent kinetic energy inferred from Seagliders: an application to the eastern Nordic Seas overflows
(Peer reviewed; Journal article, 2012-12)Turbulent mixing is an important process controlling the descent rate, water mass modification, and volume transport augmentation due to entrainment in the dense overflows across the Greenland–Scotland Ridge. These overflows, ... -
Dissolution from a liquid CO2 lake disposed in the deep ocean
(Peer reviewed; Journal article, 2003)The dissolution from a liquid CO2 lake source located at a flat ocean bottom at 3,000 m depth is investigated. Using the unsteady, two-dimensional advection–diffusion equation, temporal and spatial distribution of CO2 ... -
Dissolved Oxygen and Biochemical Oxygen Demand in the waters close to the Quelimane sewage discharge
(Master thesis, 2010-06-01)The River dos Bons Sinais Estuary is one of the most important estuaries in the central region of the Mozambican coast. It is situated between the confluence of Cuácua and Licuári rivers and the Mozambican Channel in the ... -
Diurnal Circulation of the Bolivan Altiplano. Part I: Observations
(Journal article, 2005-04)In July and August 2003 a field campaign was conducted to explore the diurnal circulation of the Bolivian Altiplano. Vertical soundings by remote-controlled aircraft yielded profiles of temperature, pressure, and humidity ... -
The Dominant Patterns of Intraseasonal Rainfall Variability in May–October and November–April over the Tropical Western Pacific
(Journal article, 2019)The space–time structure of intraseasonal (10–90 day) rainfall variability in the western tropical Pacific is studied using daily 3B42 TRMM and ERA-Interim reanalysis data for the period 1998–2014. Empirical orthogonal ... -
The Dominant Role of Brewer-Dobson Circulation on 17O-Excess Variations in Snow Pits at Dome A, Antarctica
(Journal article; Peer reviewed, 2022)Recent studies have suggested that water isotopologues in snow pits from remote East Antarctica can be influenced by the input of stratospheric water, which has anomalously high 17O-excess values. However, it remains unclear ... -
Downscaling an intense precipitation event in complex terrain: the importance of high grid resolution
(Peer reviewed; Journal article, 2017)Floods due to intense rainfall are a major hazard to both people and infrastructure in western Norway. Here steep orography enhances precipitation and the complex terrain channels the runoff into narrow valleys and small ... -
Downslope windstorm in Iceland –WRF/MM5 model comparison
(Peer reviewed; Journal article, 2011-01-05)A severe windstorm downstream of Mt. Öræfajökull in Southeast Iceland is simulated on a grid of 1 km horizontal resolution by using the PSU/NCAR MM5 model and the Advanced Research WRF model. Both models are run with a ... -
Drag coefficient reduction at very high wind speeds
(Peer reviewed; Journal article, 2006-03-31)The correct representation of the 10-m drag coefficient for momentum (K10) at extreme wind speeds is very important for modeling the development of tropical depressions and may also be relevant to the understanding of other ... -
Drivers of the marine CO2 system in the High Arctic - from the deep basins to the shallow fjords
(Doctoral thesis, 2019-02-20)The High Arctic is largely undersampled in terms of marine CO2 system data due to the cold dark season and often an extensive sea ice cover. The current understanding of the Arctic carbon cycle is thus vulnerable to both ... -
Dual lidar wind measurements along an upstream horizontal line perpendicular to a suspension bridge
(Journal article; Peer reviewed, 2021)Remote wind sensing can complement traditional anemometry at a bridge site and contribute to an improved wind-resistant design of long-span bridges. This study examines wind lidar measurement data recorded along a ... -
Dual staining with CFDA-AM and SYTOX Blue in flow cytometry analysis of UV-irradiated Tetraselmis suecica to evaluate vitality
