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 ... -
Coastal submesoscale processes and their effect on phytoplankton distribution in the southeastern Bay of Biscay
(Journal article; Peer reviewed, 2021)Submesoscale processes have a determinant role in the dynamics of oceans by transporting momentum, heat, mass, and particles. Furthermore, they can define niches where different phytoplankton species flourish and accumulate ... -
Constraining energetic slope currents through assimilation of high-frequency radar observations
(Peer reviewed; Journal article, 2015-03-11)Assimilation of high-frequency (HF) radar current observations and CTD hydrography is performed with the 4D-Var analysis scheme implemented in the Regional Ocean Modeling System (ROMS). We consider both an idealized case, ... -
The effect of vertical mixing on the horizontal drift of oil spills
(Peer reviewed; Journal article, 2018)Vertical and horizontal transport mechanisms for marine oil spills are investigated using numerical model simulations. To realistically resolve the 3-D development of a spill on the ocean surface and in the water column, ... -
Frontogenesis of the Angola-Benguela Frontal Zone
(Peer reviewed; Journal article, 2019-02-08)A diagnostic analysis of the climatological annual mean and seasonal cycle of the Angola–Benguela Frontal Zone (ABFZ) is performed by applying an ocean frontogenetic function (OFGF) to the ocean mixing layer (OML). The ... -
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 ... -
Inherent optical properties of dissolved and particulate matter in an Arctic fjord (Storfjorden, Svalbard) in early summer
(Journal article; Peer reviewed, 2022)Lysforholdene i havet spiller en nøkkelrolle for marin primærproduksjon og dermed for det hele marine økosystemet. I polområdene er det spesielt stor sesongvariasjon i lysforholdene, og mange ulike prosesser kan påvirke ... -
The mesoscale eddy field in the Lofoten Basin from high-resolution Lagrangian simulations
(Journal article; Peer reviewed, 2021)Warm Atlantic-origin waters are modified in the Lofoten Basin in the Nordic Seas on their way toward the Arctic. An energetic eddy field redistributes these waters in the basin. Retained for extended periods, the warm ... -
Norwegian Atlantic Slope Current along the Lofoten Escarpment
(Journal article; Peer reviewed, 2020-06)Observations from moored instruments are analyzed to describe the Norwegian Atlantic Slope Current at the Lofoten Escarpment (13∘ E, 69∘ N). The data set covers a 14-month period from June 2016 to September 2017 and resolves ... -
Particle aggregation at the edges of anticyclonic eddies and implications for distribution of biomass
(Peer reviewed; Journal article, 2012-06-14)Acoustic measurements show that the biomass of zooplankton and mesopelagic fish is redistributed by mesoscale variability and that the signal extends over several hundred meters depth. The mechanisms governing this ... -
A revised ocean glider concept to realize Stommel's vision and supplement Argo floats
(Journal article; Peer reviewed, 2020-02)This paper revisits Stommel's vision for a global glider network and the Argo design specification. A concept of floats with wings, so-called slow underwater gliders, is explored. An analysis of the energy or power consumption ... -
Seasonal resonance of diurnal coastal trapped waves in the southern Weddell Sea, Antarctica
(Peer reviewed; Journal article, 2017-01-30)The summer enhancement of diurnal tidal currents at the shelf break in the southern Weddell Sea is studied using velocity measurements from 29 moorings during the period 1968 to 2014. Kinetic energy associated with diurnal ... -
The "shallow-waterness" of the wave climate in European coastal regions
(Peer reviewed; Journal article, 2017-07-20)In contrast to deep water waves, shallow water waves are influenced by bottom topography, which has consequences for the propagation of wave energy as well as for the energy and momentum exchange between the waves and the ... -
Stirring across the Antarctic Circumpolar Current's southern boundary at the prime meridian, Weddell Sea
(Journal article; Peer reviewed, 2023)At the southern boundary of the Antarctic Circumpolar Current (ACC), relatively warm ACC waters encounter the colder waters surrounding Antarctica. Strong density gradients across the southern boundary indicate the presence ... -
Structure and drivers of ocean mixing north of Svalbard in summer and fall 2018
(Journal article; Peer reviewed, 2021)The Arctic Ocean is a major sink for heat and salt for the global ocean. Ocean mixing contributes to this sink by mixing the Atlantic- and Pacific-origin waters with surrounding waters. We investigate the drivers of ocean ... -
Technical note: Turbulence measurements from a light autonomous underwater vehicle
(Journal article; Peer reviewed, 2022)A self-contained turbulence instrument from Rockland Scientific was installed on a light autonomous underwater vehicle (AUV) from OceanScan Marine Systems and Technology Lda. We report on the data quality and discuss ...
