Seasonal dynamics of autotrophic and heterotrophic plankton metabolism and PCO2 in a subarctic Greenland fjord
Biological metabolic kinetics Greenland fjord
2014/10/16
We measured net planktonic community production (NCP), community respiration (CR), and gross primary
production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...
Seasonal rates of benthic primary production in a Greenland fjord measured by aquatic eddy correlation
benthic aquatic eddy correlation
2014/10/16
We present the first year-round estimates of benthic primary production at four contrasting shallow (3–22 m
depth) benthic habitats in a southwest Greenland fjord. In situ measurements were performed...
Role of sulfate reduction and methane production by organic carbon degradation in eutrophic fjord sediments (Limfjorden, Denmark)
Role of sulfate reduction methane production organic carbon degradation eutrophic fjord sediments
2014/4/17
The anaerobic mineralization of buried organic matter through sulfate reduction and methanogenesis was studied in 2-m-long piston cores of organic-rich, silty-clay sediment from two sites in Limfjorde...
Comparison of zooplankton vertical migration in an ice-free and a seasonally ice-covered Arctic fjord: An insight into the influence of sea ice cover on zooplankton behavior
zooplankton vertical migration sea ice
2014/4/16
We present observations of zooplankton diel vertical migration (DVM) over a period of 2 yr in an ice-free and
a seasonally ice-covered Arctic fjord. The contrasting environments permitted assessment ...
Direct determination of nitrogen cycling rates and pathways in Arctic fjord sediments (Svalbard, Norway)
pathways nitrogen cycling rates
2014/4/16
Results from a study of benthic nitrogen cycling in two Arctic fjords are presented. Intact sediment core
incubations were used to quantify net fluxes of dissolved inorganic nitrogen, organic nitroge...
Fluid flow features in fjord-fill deposits,Ullsfjorden,North Norway
Fluid flow features fjord-fill deposits Ullsfjorden
2009/12/3
Fluid flow features are found with high-resolution acoustic data from Ullsfjorden, North Norway. The glacimarine and marine fjord-fill sediments have a total thickness of up to 150 m. The seafloor is ...
The Late Neoproterozoic Smalfjord Formation of the Varanger Peninsula in northern Norway:a shallow fjord deposit
Late Neoproterozoic Smalfjord Formation Varanger Peninsula shallow fjord deposit
2009/12/3
The Smalfjord Formation in the Varangerfjorden area of northern Norway was deposited as valley fill during an interglacial period of the Varangerian (Marinoan) glaciation. The paleovalley was initiall...
Dating submarine mass movements triggered by earthquakes in the Upper Saguenay Fjord,Quebec,Canada
submarine mass movements earthquakes Upper Saguenay Fjord
2009/12/3
Using some new and previously published sedimentation rate data the relationship between sedimentation rate and distance from sediment source was statistically modelled for the Saguenay Fjord, Canada....
A Late Holocene climate history from the Malangen fjord,North Norway,based on dinoflagellate cysts
Late Holocene climate history Malangen fjord dinoflagellate cysts
2009/12/2
The Malangen fjord, a high Boreal/low Arctic fjord in northern Norway, reflects Atlantic Water heat flux. Studies of dinoflagellate cyst assemblages,reflecting the fjord surface water masses, have bee...
Environmental response of living benthic foraminifera in Kiel Fjord,SW Baltic Sea
Environmental response living benthic foraminifera Kiel Fjord
2009/10/22
The living benthic foraminiferal assemblages in the Kiel Fjord (SW Baltic Sea) were investigated in the years 2005 and 2006. The faunal studies were accomplished by geochemical analyses of surface sed...
Deep Water Exchanges in a Sill Fjord：A Stochastic Process
Deep Water Exchanges Sill Fjord Stochastic Process
2009/4/2
A statistical theory for the behavior of a fjord system with a sill is formulated and leads to the establishment of conditional and marginal distribution functions for the homogeneous deep water densi...
Vertical Diffusion Driven by Internal Waves in a Sill Fjord
Vertical Diffusion Driven Internal Waves Sill Fjord
2009/3/7
A new mechanism, the breaking of internal waves, is proposed to explain vertical mixing within the lower layers of sill fjords. The generation of the waves at the sill of a fjord is modelled assuming ...
Measurements made in Cambridge Bay, N.W.T., during the winter show that the breaking of internal waves on the shore influences downward salt transport from the homogeneous surface layer produced by sa...
Currents, temperature, salinity, wind, runoff and water level were observed for a month in the Jøsen-fjord of southern Norway. Tide gages and currents show little semidiurnal tide. There is a s...
A Simple Model of Fjord and Coastal Circulation Interaction
Simple Model Fjord Coastal Circulation Interaction
2009/2/10
The dynamical interaction of a narrow fjord with a wind-driven coastal regime is investigated using a linear, two-layer numerical model. The Coriolis acceleration is important in the coastal regime bu...
