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...
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...
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...
Seasonal Mixing Processes in an Arctic Fjord System
Seasonal Mixing Processes Arctic Fjord System
2009/2/7
Studies of water movement in the Aafardlikavsâ/Qaumarujuk fjord system in West Greenland have barn carried out in order to understand the movement of mine tailings discharged into Agfardlikavs&a...
The Control of Fjord Circulation by Fortnightly Modulation of Tidal Mixing Processes
Fjord Circulation Fortnightly Modulation Tidal Mixing Processes
2008/12/19
Tidal processes that control basin–ocean water exchange across a sill, namely, the fortnightly modulation of mixing intensity associated with the spring-neap tidal cycle, are examined. The study proce...
Observed Damping of Barotropic Seiches through Baroclinic Wave Drag in the Gullmar Fjord
Barotropic Seiches Baroclinic Wave Drag Gullmar Fjord
2008/11/18
Baroclinic wave drag, due to internal wave generation at steep topography, is shown to be a mechanism that effectively subdues barotropic seiches in fjords. A two-layer model for a fjord with a sill a...
The Internal Seiches in Gullmar Fjord. Part I: Dynamics
Internal Seiches Gullmar Fjord Dynamics
2008/8/1
Internal seiche motions with period 1–3 days in Gullmar Fjord are investigated based on mooring data with high vertical and time resolution. The period and structure of the internal seiches are well d...
The Internal Seiches in Gullmar Fjord. Part II: Contribution to Basin Water Mixing
Internal Seiches Gullmar Fjord Basin Water Mixing
2008/8/1
The mixing in the basin water (the water below sill level) of Gullmar Fjord has been investigated with the main focus on the contribution from internal seiches. A companion paper reports evidence for ...
Tidally Forced Internal Wave Mixing in a k– Model Framework Applied to Fjord Basins
Tidally Forced Internal Wave Mixing k– Model Framework Fjord Basins
2008/6/30
A simple method for including tidally forced internal wave mixing in a two-equation turbulence closure framework, the k– model, is presented. The purpose is to model the vertical mixing in the basin w...
