Creator:: Holman, R. A. and Bowen, A. J.
Abstract:: In shallow water, any two waves of the same frequency are shown to produce complex patterns of drift velocity above the sea bed. If the longshore components λ₁, λ₂ of the wave numbers of the two waves are different, these steady flow patterns exhibit a longshore periodicity of wave number...

Creator:: Shearman, R. Kipp
Abstract:: Observations from the Coastal Mixing and Optics (CMO) moored array (deployed from August 1996 through June 1997) and supplemental moored observations are used to describe near-inertial current variability over the New England shelf. Near-inertial band current variance comprises 10–20% of the total observed current variance, and has episodic peak speeds...

Creator:: Holman, R. A.
Abstract:: Field measurements of onshore and longshore velocities in the surf zone have been obtained on Martinique Beach, Nova Scotia, for the purpose of investigating the dynamics of the infragravity band (0.003- 0.03 Hz) of the spectra. A total of35 data runs were obtained during a 1-week period. Of particular interest...

Creator:: Caldwell, Douglas R.
Abstract:: In a discussion of the turbulence characteristics of patches of 'microstructure' in the ocean, the hypothesis advocated by Gibson (1982), that the patches are produced by very rare but extremely powerful turbulence-generating events which usually have 'fossilized' before their observation, is contrasted with the hypothesis of a turbulence field driven...

Abstract:: Swash hydrodynamics were investigated on an intermediate beach using runup data obtained from video images. Under mild, near-constant, offshore wave conditions, the presence of a sandbar and the tidally controlled water depth over its crest determined whether most of the incoming waves broke before reaching the shoreline. This forced a...

Creator:: Chriss, T.M. and Caldwell, Douglas R.
Abstract:: An experiment in 199 m of water on the Oregon shelf produced continuous current speed profiles down to the sediment-water interface. These profiles show that the velocity structure above the viscous sublayer is consistent with that expected when form drag influences the boundary layer flow. They show two logarithmic-profile regions,...

Creator:: Chriss, T.M. and Caldwell, Douglas R.
Abstract:: Experiments conducted on the Oregon continental shelf in June 1979 indicate that the boundary layer flow at the seafloor was hydrodynamically smooth. Fine-resolution velocity profiles are used to test the assumption that the flow behaved like a universally similar, neutrally buoyant flow over a smooth wall. The non-dimensional thickness of...

Creator:: Shell, K. M., Frouin, R., Nakamoto, S., and Somerville, R. C. J.
Abstract:: Phytoplankton alter the absorption of solar radiation, affecting upper ocean temperature and circulation. These changes, in turn, influence the atmosphere through modification of the sea surface temperature (SST). To investigate the effects of the present-day phytoplankton concentration on the atmosphere, an atmospheric general circulation model was forced by SST changes...

Abstract:: Collocated Moderate Resolution Imaging Spectroradiometer (MODIS) imagery and Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) 532 nm total attenuated backscatter coefficients were used to identify 50 km scale segments for ocean regions that had only a single layer of marine stratocumulus. On the basis of whether the underlying ocean...

Abstract:: A 38-day, 5990-cast microstructure study on the equator performed during the onset of the 1991-1993 El Nino shows the effect on small-scale activity at 140°W of an equatorial Kelvin wave. By using two ships, data were taken continuously from November 4 to December 12, 1991, near the National Oceanic and...
