The maintenance of the subsurface chlorophyll maximum in the stratified western Irish Sea
subsurface chlorophyll maximum nutrient fl ux turbulent mixing internal waves Irish Sea
2014/4/1
The diapycnal flux of nitrate from the deep water provides a limit on new production in the subsurface
chlorophyll maximum (SCM) during summer in stratified shelf seas. Here we estimate t...
Modeling and Assessing a New Warship Maintenance System
capability assessment planning optimization heuristic regulation warship maintenance system
2011/9/9
The authors developed a prototype of a warship maintenance system. The process started by defining the maintenance requirements of warship equipment. Next, a planning scheme was development for a main...
Observations of turbulent mixing in a phytoplankton thin layer: Implications for formation, maintenance, and breakdown
Observations of turbulent mixing formation maintenance
2014/4/18
Coincident measurements of chlorophyll a (Chl a) and temperature microstructure from Monterey Bay,
California, U.S.A., are used to investigate the dynamics of a phytoplankton thin layer in the contex...
Some Two-Layer Models of the Shelf-Slope Front：Geostrophic Adjustment and its Maintenance
Shelf-Slope Front two-layered frontal system Geostrophic Adjustment
2009/2/6
Two conceptual models of a two-layered frontal system are presented to study the wintertime shelf-slope front. The first model examines the geostrophic adjustment over a step topography after the fall...
On the Maintenance of the Subtropical Front and its Associated Countercurrent
Subtropical Front wind-driven circulation thermally driven flow
2009/1/20
In the North Pacific and Atlantic Oceans, the Subtropical Countercurrent is an eastward flow across the Subtropical Gyre at a latitude where a classical wind-driven circulation theory would predict a ...
A Simple Model of the Formation and Maintenance of the Shelf/Slope Front in the Middle Atlantic Bight
Shelf/Slope Front Middle Atlantic Bight
2009/1/12
The strong salinity and temperature gradients across the shelf/slope front in the Middle Atlantic Bight often compensate such that the cross-front density gradient is nearly eliminated. The suggests t...
On the Potential Vorticity Structure of Weakly Ventialted Isopycnals：A Theory of Subtropical Mode Water Maintenance
Potential Vorticity Structure Weakly Ventialted Isopycnals Subtropical Mode Water Maintenance
2009/1/12
A two-layer model of the general circulation including wind and thermal forcing is discussed. The flow in each layer is geostrophic, hydrostatic and obeys linear potential vorticity constraints. The e...
The Formation and Maintenance of Density Fronts on the U.S. Southeastern Continental Shelf during Winter
Density Fronts U.S. Southeastern Continental Shelf Winter
2009/1/12
Density fronts on the U.S. southeastern continental shelf, during winter, am formed by (i) breakdown of the shelf-break front by Gulf Stream meanders or strong southward winds or both, (ii) shoreward ...
Formation and Maintenance of Shelfbreak Fronts in an Unstratified Flow
Shelfbreak Fronts Unstratified Flow passive tracer front
2008/12/24
A depth-averaged model with no density variations was used by Chapman to describe the formation of a passive tracer front at a shelfbreak. The relevance of this frontogenesis mechanism to cases that a...
The Role of Stratification in the Formation and Maintenance of Shelf-Break Fronts
Shelf-Break Fronts continental shelf stratified fluid
2008/12/22
A mechanism is described for the formation or a front at the edge of a continental shelf in an initially linearly stratified fluid lacking horizontal density gradients. A primitive equation numerical ...
Eddy Maintenance and Attrition in a Vertically Sheared Current under Arctic Ice
Eddy Maintenance Attrition Vertically Sheared Current Arctic Ice
2008/10/23
Steady drift of an ice cover produces a vertically sheared current in the upper ocean of the Arctic. Under the ice cover, mesoscale shallow brine and freshening sources generate submerged anticyclones...
Formation and Maintenance of a Polynya in the Weddell Sea
Formation Maintenance Polynya Weddell Sea
2008/7/11
A dynamic–thermodynamic sea ice–mixed layer model for the Weddell Sea is complemented by a simple, diagnostic model to account for local sea ice–atmosphere interaction. To consider the atmospheric inf...
Convergences and divergences and thin layer formation and maintenance
Convergences divergences thin layer formation maintenance
2014/4/22
The formation and maintenance of thin layers in the presence of turbulent diffusion is considered through the development of a formal framework that evaluates the balance between convergence mechanism...
Evolutionary stoichiometry: The role of food quality for clonal differentiation and hybrid maintenance in a Daphnia species complex
Evolutionary stoichiometry The role of food quality for clonal differentiation hybrid maintenance Daphnia species complex
2014/4/22
Interspecific hybridization is a common phenomenon among Daphnia species (Crustacea: Anomopoda); interspecific hybrids and parental species have been shown to be ecologically differentiated and often ...
