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...
Longshore Currents and the Onset of Upwelling over Bottom Slope
Longshore Currents Onset of Upwelling Bottom Slope
2009/3/26
The evolution of longshore currents produced by upwelling on an f-plane over shelf-like bottom topography for times long compared to a barotropic spin-up time, but short compared to a diffusion time, ...
Longshore Currents, Upwelling and Bottom Topography
Longshore Currents Bottom Topography Upwelling
2009/3/26
The effect of shelf-like bottom topography on a steady, linear, stratified, three-dimensional model of coastal upwelling is examined. It is shown that the presence of the bottom slope 1) reduces the r...
Pressure fluctuations on the deep seafloor at frequencies below inertial and tidal have been measured. Between 0.1 and 1 cycle per day the variance is about 2 mb2, spectra diminish with increasing fre...
MODE：IGPP Measurements of Bottom Pressure and Temperature
IGPP Measurements Bottom Pressure Temperature
2009/3/24
We review the MODE deployment of IGPP bottom instruments, together with preliminary tests on the Pacific seafloor and in the laboratory. Pressure and temperature were measured with quartz-crystal tran...
Continental Shelf Waves and Alongshore Variations in Bottom Topography and Coastline
Continental Shelf Waves Bottom Topography Alongshore Variations Coastline
2009/3/7
The effects of alongshore variations in bottom topography and coastline on the wind-stress-forced barotropic motion over a continental shelf and slope are studied. Perturbation methods are used to obt...
Temperature Steps in Lake Kivu：A Bottom Heated Saline Lake
Temperature Steps Lake Kivu Bottom Heated Saline Lake
2009/3/7
Vertical profiles of temperature microstructure in Lake Kivu were obtained with “mini-microstructure recorders” developed by C.S. Cox and William Johnson at Scripps Institution of Oceanography. The pr...
Residual Flow and Boundary Shear Stress in the Turbulent Bottom Layer Beneath Waves
Residual Flow Turbulent Bottom Layer Beneath Waves
2009/3/7
A model is considered of the turbulent bottom boundary layer beneath waves. Closure is effected at the level of the turbulent energy equation and numerical solutions are obtained by a combination of f...
The Effects of a Variable Coriolis Parameter, Coastline Curvature and Variable Bottom Topography on Continental Shelf Waves
Variable Coriolis Parameter Coastline Curvature Variable Bottom Topography Continental Shelf Waves
2009/3/7
The effects of a variable Coriolis parameter, coastline curvature and variable bottom topography on continental shelf waves are examined for the case when the variations occur on a length scale much g...
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...
A Study of Tidal Energy Dissipation and Bottom Stress in an Estuary
Tidal Energy Dissipation Bottom Stress Estuary
2009/2/19
A Method for inferring an area-averaged bottom stress and energy dissipation rate in a tidal estuarine channel is presented. The one-dimensional continuity and momentum relations are developed using s...
Some Observations of Baroclinic Diurnal Tides over a Near-Critical Bottom Slope
Baroclinic Diurnal Tides Baroclinic Diurnal Tides
2009/2/19
The time-depth structure of the baroclinic diurnal tide has been examined with the aid of current and temperature profiles on the West Florida Continental Shelf. Of interest is the fact that the diurn...
The Influence of Bottom Topography on Upwelling off Peru
Bottom Topography Upwelling off Peru
2009/2/18
The x-y-t, two-layer β-plane numerical model developed by Hurlburt (1974) is used to examine the upwelling system off Peru. The region off Peru from 14 to 15°30's is one of strong and persistent upwel...
Boundary Layer under Near-Inertial Internal Waves over a Critically Sloping Bottom
Boundary Layer Critically Sloping Bottom Near-Inertial Internal Waves
2009/2/18
Internal waves reflecting off sloping bottoms have been shown to have boundary-layer scales proportional to ν½ (ν is viscosity). As the characteristic slope of the wave approaches the slope of ...
Propagation of Barotropic Continental Shelf Waves over Irregular Bottom Topography
Barotropic Continental Shelf Waves Irregular Bottom Topography
2009/2/16
Using a geometry which roughly approximates that of a typical continental shelf and slope, the effects of a random bottom topography on free barotropic shelf waves are found. The bathymetric irregular...
