Exploring the Arctic margins and the Central Arctic Ocean:An introduction
Arctic margins Central Arctic Ocean introduction
2009/12/2
The Arctic is one of the few underexplored frontiers on the Earth. The present NJG issue consists of papers presented at the Arctic Conference Days in Tromsø in September 2007. The 10 papers pr...
The Arctic Ocean marine carbon cycle:evaluation of air-sea CO2 exchanges,ocean acidification impacts and potential feedbacks
Arctic Ocean marine carbon cycle evaluation air-sea CO2 exchanges ocean acidification impacts
2010/1/21
At present, although seasonal sea-ice cover mitigates atmosphere-ocean gas exchange, the Arctic Ocean takes up carbon dioxide (CO2) on the order of ?66 to ?199 Tg C year?1 (1012 g C), contributing 5–1...
Calcium carbonate saturation in the surface water of the Arctic Ocean:undersaturation in freshwater influenced shelves
Calcium carbonate saturation surface water Arctic Ocean freshwater influenced shelves
2010/1/21
In the summer of 2005, we sampled surface water and measured pH and total alkalinity (AT) underway aboard IB Oden along the Northwest Passage from Cape Farewell (South Greenland) to the Chukchi Sea. W...
Ozone in the boundary layer air over the Arctic Ocean: measurements during the TARA transpolar drift 2006–2008
Ozone boundary layer air Arctic Ocean measurements TARA transpolar drift
2009/7/22
A full year of measurements of surface ozone over the Arctic Ocean far removed from land is presented (81° N–88° N latitude). The data were obtained during the drift of the French schooner TARA betwee...
A Numerical Investigation of Arctic Ocean Dynamics
Numerical Investigation Arctic Ocean Dynamics
2009/4/2
A barotropic numerical model of the Arctic Ocean is formulated to include irregular basin shape, variable bathymetry, lateral friction, bottom drag, and nonlinear advection terms. Source-sink distribu...
Numerical Simulation of the Arctic Ocean Circulation
Numerical Simulation Arctic Ocean Circulation
2009/3/7
The circulation of the Arctic Ocean and Greenland Sea is simulated using the 1969 numerical model of Bryan and Cox. The coastline and bottom topography of the region are resolved by a 110 km horizonta...
A Study of Oceanic Boundary-Layer Characteristics Including Inertial Oscillation at Three Drifting Stations In the Arctic Ocean
Oceanic Boundary-Layer Characteristics Inertial Oscillation Three Drifting Stations the Arctic Ocean
2009/2/16
Measurements of surface drift and near-surface currents taken during August 1975, at drifting ice stations of the AIDJEX experiment in the central Arctic, are used to infer the response of the upper o...
Model for the Thickness and Salinity of the Upper Layer in the Arctic Ocean and the Relationship between the Ice Thickness and Some External Parameters
Upper Layer Arctic Ocean Ice Thickness External Parameters
2009/2/10
This paper presents a dynamical model for the salinity and thickness of the upper layer in the Arctic. The parameters are the river runoff to the Arctic, the buoyancy supply through the Bering Strait,...
Internal Waves in the Arctic Ocean：Comparison with Lower-Latitude Observations
Internal Waves Arctic Ocean Lower-Latitude Observations
2009/1/15
A thermistor chain was moored below the pack ice from 50–150 m in the Arctic Ocean for five days in 1981. Oscillations in temperature are attributed to the vertical dispalcement of internal waves. The...
A One-Dimensional Time-Dependent Model for the Vertical Stratification of the Upper Arctic Ocean
One-Dimensional Time-Dependent Model Vertical Stratification Upper Arctic Ocean
2008/12/30
A one-dimensional time-dependent model of the upper Arctic Ocean is presented. It describes the circulation above a dynamically passive reservoir of Atlantic water. The model is driven by freshwater r...
Seasonal changes in planktonic bacterivory rates under the ice-covered coastal Arctic Ocean
Seasonal changes planktonic bacterivory rates the ice-covered coastal Arctic Ocean
2014/4/21
Bacterivory was determined in surface waters of Franklin Bay, western Arctic, over a seasonal ice-covered period (winter-spring, 2003-2004). The objectives were to obtain information on the functionin...
An Eddy Parameterization Based on Maximum Entropy Production with Application to Modeling of the Arctic Ocean Circulation
Eddy Parameterization Maximum Entropy Production Arctic Ocean Circulation
2008/8/12
An eddy parameterization derived from statistical mechanics of potential vorticity is applied for inviscid shallow-water equations. The solution of a variational problem based on the maximum entropy p...

Determining net dissolved organic hydrographically complex western Arctic Ocean
2014/4/22
Each spring and summer, the Chukchi Sea in the western Arctic Ocean experiences a short but intense
phytoplankton bloom that is controlled by sea ice cover, nutrient availability, and river runoff. D...
