Characterizing wave- and current- induced bottom shear stress: U.S. middle Atlantic continental shelf
Waves and currents create bottom shear stress, a force at the seabed that influences sediment texture distribution, micro-topography, habitat, and anthropogenic use. This paper presents a methodology for assessing the magnitude, variability, and driving mechanisms of bottom stress and resultant sediment mobility on regional scales using numerical model output. The analysis was applied to the Mi...
متن کاملSpectral particulate attenuation and particle size distribution in the bottom boundary layer of a continental shelf
Spectral attenuation and absorption coefficients of particulate matter and colocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. Within the bottom boundary layer (BBL) the magnitude of the beam attenuation decreased and its spectral shape became steeper with distance from th...
متن کاملFall-Winter Current Reversals on the Texas-Louisiana Continental Shelf
Fall-winter recurrence of current reversal from westward to eastward is identified on the Texas-Louisiana continental shelf using the current meter [Texas-Louisiana Shelf Physical Oceanography Program (LATEX-A)] and near surface drifting buoy [Surface Current and Lagrangian Drift Program (SCULP-1)] observations in 1993 and 1994. Reversal events roughly satisfy the Poisson distribution with one ...
متن کاملModeling the dynamics of continental shelf carbon.
Continental margin systems are important contributors to global nutrient and carbon budgets. Effort is needed to quantify this contribution and how it will be modified under changing patterns of climate and land use. Coupled models will be used to provide projections of future states of continental margin systems. Thus, it is appropriate to consider the limitations that impede the development o...
متن کاملShear-induced convective mixing in bottom boundary layers on slopes
Field data from a stratified lake demonstrate that buoyancy-driven convective mixing can be an important mechanism for the formation of well-mixed bottom boundary layers (BBLs) on slopes. Convective turbulence is caused by differential transport of stratified water masses along the slope of a basin. Because the current velocity usually decreases toward the sediment, water at some distance from ...
