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:: Guedes, R. M. C., Bryan, K. R., Coco, G., and Holman, R. A.
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:: Spinelli, G. A. and Harris, R. N.
Abstract:: Water circulating through oceanic lithosphere extracts large quantities of heat, affecting magmatic, tectonic, geochemical, and microbial processes. Numerous estimates for the amount of hydrothermal heat extraction have been made on the basis of the difference between the predicted and observed heat flux across the seafloor. These methods have assumed a...

Creator:: Holman, Robert A., Symonds, G., Thornton, E. B., and Ranasinghe, R.
Abstract:: Four years of daily time exposure images from an embayed beach were examined to study the spacing, persistence, and location preferences of rips in a natural rip channel system. A total of 5271 rip channels was observed on 782 days. Occurrence statistics showed no evidence of the preferred location pattern...

Creator:: Wilson, G. W., Özkan-Haller, H. Tuba, and Holman, R. A.
Abstract:: A methodology is described for assimilating observations in a steady state twodimensional horizontal (2‐DH) model of nearshore hydrodynamics (waves and currents), using an ensemble‐based statistical estimator. In this application, we treat bathymetry as a model parameter, which is subject to a specified prior uncertainty. The statistical estimator uses state augmentation...

Creator:: Clark, H. L, Harwood, R. S., Mote, Philip W., and Read, W. G.
Abstract:: The Microwave Limb Sounder (MLS), an instrument on the Upper Atmosphere Research Satellite (UARS), measures water vapor in the upper troposphere, with best sensitivity at the standard UARS level at 215 hPa. In this paper, we analyze the MLS observations with a view to characterizing the temporal and zonal variations...

Creator:: Lee, Z. P., Carder, K. L., Steward, R. G., Peacock, T. G., Davis, C. O., and Patch, J. S.
Abstract:: Empirical algorithms for the total absorption coefficient and absorption coefficient by pigments for surface waters at 440 nm were developed by applying a quadratic formula that combines two spectral ratios of remote-sensing reflectance. For total absorption coefficients ranging from 0.02 to 2.0 m⁻¹, a goodness of fit was achieved between...

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:: 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:: Twohy, Cynthia, Clarke, A. D., Warren, S. G., Radke, L. F., and Charlson, R. J.
Abstract:: Using the counterflow virtual impactor, a new instrument for sampling cloud droplets, measurable levels of light-absorbing material were found to exist inside droplets in stratocumulus clouds off the coast of southern California. Eighty percent of the samples of droplet residue material had light absorption coefficients ranging from 6 to 20...
