Low-Temperature Hydrothermal Plumes in the Near-Bottom Boundary Layer at Endeavour Segment,Juan de Fuca Ridge
Low-Temperature Hydrothermal Plumes Near-Bottom Boundary Layer Endeavour Segment,Juan Fuca Ridge
2015/7/14
Low-temperature (typically 5–75°C) fluid, commonly referred to as "diffuse" hydrothermal flow, emanates from fractures over a significant portion of the Juan de Fuca Ridge seafloor in the Northeast Pa...
On the Structure and Dynamics of the Oceanic Bottom Boundary Layer
Oceanic Bottom Boundary Layer Structure Dynamics
2009/2/23
The Mellor and Yamada (1974) Level II turbulence closure scheme is used to study the oceanic bottom boundary layer (BBL). The model is tested against observations of the BBL obtained on the western Fl...
The Bottom Boundary Layer in the Eastern Tropical Pacific
Bottom Boundary Layer Eastern Tropical Pacific
2009/2/16
Vertical and horizontal structure of near-bottom currents at two locations in the eastern tropical Pacific (9°26′N, 151°17′W; 14°38′N, 125°29′W) have been studied. Low-frequency currents at these site...
The Effect of a Bottom Boundary Layer on the Stability of a Baroclinic Zonal Current
Bottom Boundary Layer Baroclinic Zonal Current
2009/2/8
The effect of a depth-limited bottom boundary layer on the stability of a baroclinic zonal current is investigated. The model is of a two-layer quasi-geostrophic flow. Limiting the height of the bound...
A Numerical Study of the Interaction between a Deep Cold Jet and the Bottom Boundary Layer of the Ocean
second order turbulence closure bottom boundary layer Cold Filament
2008/12/27
A two-dimensional (x-z) primitive equation model is used to study the interaction between a deep cold jet on a sloping bottom and the bottom boundary layer (BBL) of the deep ocean. Two closure schemes...
The Bottom Boundary Layer Over the Northern California Shelf
Bottom Boundary Layer Northern California Shelf
2008/12/24
Moored temperature and shipboard CTD observations from a northern California coastal upwelling region reveal variable bottom mixed-layer heights that are typically 5–15 m, but occasionally exceed 50 m...
A Bottom Boundary Layer-resolving Three-Dimensional Tidal Model：A Sensitivity Study of Eddy Viscosity Formulation
three-dimensional hydrodynamic model Eddy Viscosity Formulation bottom boundary layer
2008/12/18
A three-dimensional hydrodynamic model of the Irish Sea that resolves the bottom boundary layer, including the logarithmic layer, is developed. A finite-difference grid is employed in the horizontal, ...
A Coupled Hydrodynamic–Bottom Boundary Layer Model of Ekman Flow on Stratified Continental Shelves
Hydrodynamic–Bottom Boundary Layer Model Ekman Flow Stratified Continental Shelves
2008/12/16
This paper describes a hydrodynamic model with turbulent energy closure that uses a simplified wave-current interaction model of the bottom boundary layer to compute bed drag coefficients. The coupled...
