Circulation and water masses beneath the northern Ronne Ice Shelf, Antarctica
(Journal article; Peer reviewed, 2004-12-14)We present oceanographic data from beneath the northern Ronne Ice Shelf. The data were collected during the austral summer of 2002–2003 from four sites located near the ice front in the Ronne Depression. They consist of ... -
Effects of altitude and aerosol on UV radiation
(Journal article; Peer reviewed, 2006-01-10)Measurements of erythemally weighted UV radiation during about 600 days at different sites in Bolivia and Germany ranging from 550 to 5240 m above sea level have been used to derive the altitude effect AE under cloud-free ... -
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 ... -
Interannual variability and ventilation timescales in the ocean cavity beneath Filchner-Ronne Ice Shelf, Antarctica
(Peer reviewed; Journal article, 2004-04-20)Multiyear time series of ocean current and temperatures from beneath Filchner-Ronne Ice Shelf, Antarctica, demonstrate both seasonal and interannual variability. The seasonal signal is visible at all measurement sites, ... -
Mixing in the stratified interface of the Faroe Bank Channel overflow: the role of transverse circulation and internal waves
(Peer reviewed; Journal article, 2011-07)The overflow of cold water across the Faroe Bank Channel sill is a significant volume flux of dense water to the North Atlantic Ocean. Using observations of hydrography, current and microstructure from a 1 week cruise and ... -
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 ... -
Mixing rates and vertical heat fluxes north of Svalbard from Arctic winter to spring
(Peer reviewed; Journal article, 2017-06)Mixing and heat flux rates collected in the Eurasian Basin north of Svalbard during the N-ICE2015 drift expedition are presented. The observations cover the deep Nansen Basin, the Svalbard continental slope, and the shallow ... -
North Sea circulation: Atlantic inflow and its destination
(Peer reviewed; Journal article, 2006-12-22)This study investigates the Atlantic inflow to the North Sea; its variabil- ity, pathways and destination. Results from a numerical model show that the variability of Atlantic inflow is dependent on the inflow location. ... -
Observations of highly regular oscillations in the overflow plume downstream of the Faroe Bank Channel
(Peer reviewed; Journal article, 2006-12-23)The Faroe Bank Channel (FBC) is the deepest connection between the Atlantic Ocean and the Nordic Seas. This work describes the dynamic properties of the plume of dense overflow water descending from the Faroe Bank Channel ... -
On the effect of topography and wind on warm water inflow— An idealized study of the southern Weddell Sea continental shelf system
(Peer reviewed; Journal article, 2017-03)An idealized eddy-resolving numerical model, with topographic features common to the southern Weddell Sea, is constructed to study mechanisms through which warm deep water enters a wide continental shelf with a trough. The ... -
Temporal and spatial variability of the sea surface salinity in the Nordic Seas
(Peer reviewed; Journal article, 2002-11-02)In this paper, the temporal and spatial variability of the sea surface salinity (SSS) in the Nordic Seas is investigated. The data include a Russian hydrographical database for the Nordic Seas and daily to weekly observations ... -
Water mass modification in an Arctic fjord through cross-shelf exchange: The seasonal hydrography of Kongsfjorden, Svalbard
(Journal article; Peer reviewed, 2005-12-08)Kongsfjorden and the West Spitsbergen Shelf is a region whose seasonal hydrography is dominated by the balance of Atlantic Water, Arctic waters, and glacial melt. Regional seasonality and the cross-shelf exchange processes ... -
Wind stress mediated variability of the Filchner Trough overflow, Weddell Sea
(Peer reviewed; Journal article, 2018-05-06)The Filchner Trough (FT) is a key site for exchange of water masses between the Weddell Sea continental shelf and the deep ocean. Cold and dense Ice Shelf Water (ISW), a precursor for Antarctic Bottom Water, flows north ...
