The Horizontal Momentum Balance in the Marine Atmospheric Boundary Layer during CODE-2
Publisher: American Meteorological Society
Abstract: The horizontal momentum balance in the marine atmospheric boundary layer during the Coastal Ocean Dynamics Experiment (CODE) is analyzed, using meteorological data from an array of surface moorings. Previous studies have ...
Asymmetric Behavior of an Oceanic Boundary Layer above a Sloping Bottom
Publisher: American Meteorological Society
Abstract: The effects of stratification, planetary rotation and a sloping bottom combine to produce an asymmetric response in which the characteristics of an oceanic bottom boundary layer depend on the direction, in addition to the ...
Buoyancy Arrest and Bottom Ekman Transport. Part II: Oscillating Flow
Publisher: American Meteorological Society
Abstract: The effects of a sloping bottom and stratification on a turbulent bottom boundary layer are investigated for cases where the interior flow oscillates monochromatically with frequency ?. At higher frequencies, or small slope ...
Buoyancy Arrest and Bottom Ekman Transport. Part I: Steady Flow
Publisher: American Meteorological Society
Abstract: It is well known that along-isobath flow above a sloping bottom gives rise to cross-isobath Ekman transport and therefore sets up horizontal density gradients if the ocean is stratified. These transports in turn eventually ...
Observing Directional Properties of Ocean Swell with an Acoustic Doppler Current Profiler (ADCP)
Publisher: American Meteorological Society
Abstract: Acoustic Doppler current profilers (ADCPs) are widely used for routine measurements of ocean currents and waves in coastal environments. These instruments have the basic capability to measure surface wave frequency?directional ...
Subinertial Currents on the Southern Califoinia Shelf
Publisher: American Meteorological Society
Abstract: Subinertial currents on the southern California shelf are investigated using observations from a current meter array deployed near San Diego during the summer, fall and winter of 1978/79. This region is characterized by ...
Dynamics of the Bottom Boundary Layer on the Northern California Shelf
Publisher: American Meteorological Society
Abstract: Time-series measurements of velocity, temperature, and conductivity on the northern California shelf during two winter seasons permit an observational test, in vertically integrated form, of a simple set of subinertial ...
Evaluation and Recommendations for Improving the Accuracy of an Inexpensive Water Temperature Logger
Publisher: American Meteorological Society
Abstract: nset's HOBO U22 Water Temp Pros are small, reliable, relatively inexpensive, self-contained temperature loggers that are widely used in studies of oceans, lakes, and streams. An in-house temperature bath calibration of 158 ...
Coral Reef Drag Coefficients—Surface Gravity Wave Enhancement
Publisher: American Meteorological Society
Abstract: AbstractA primary challenge in modeling flow over shallow coral reefs is accurately characterizing the bottom drag. Previous studies over continental shelves and sandy beaches suggest surface gravity waves should enhance ...
Coral Reef Drag Coefficients – Water Depth Dependence
Publisher: American Meteorological Society
Abstract: major challenge in modeling the circulation over coral reefs is uncertainty in the drag coefficient because existing estimates span two orders of magnitude. Current and pressure measurements from five coral reefs are used ...
