Creator:: Lerczak, James A. and Geyer, W. Rockwell
Abstract:: The dynamics of lateral circulation in an idealized, straight estuary under varying stratification conditions is investigated using a three-dimensional, hydrostatic, primitive equation model in order to determine the importance of lateral circulation to the momentum budget within the estuary. For all model runs, lateral circulation is about 4 times as...

Creator:: Simpson, James J. and Paulson, Clayton A.
Abstract:: Observations of sea surface temperature and wave height were made from a large, manned spar buoy (R/P FLIP) ~100 km off the coast of Baja California. Surface temperature was measured with a radiation thermometer which viewed a disc on the surface 12 cm in diameter. The instrument responded to frequencies...

Creator:: Paulson, Clayton A. and Simpson, James J.
Abstract:: Observations were made of downward solar radiation as a function of depth during an experiment in the North Pacific (35°N, 155°W). The irradiance meter employed was sensitive to solar radiation of wavelength 400–1000 nm arriving from above at a horizontal surface. Because of selective absorption of the short and long...

Creator:: Zaron, Edward D. and Moum, James N.
Abstract:: A reexamination of turbulence dissipation measurements from the equatorial Pacific shows that the turbulence diffusivities are not a simple function of the gradient Richardson number. A widely used mixing scheme, the K-profile parameterization, overpredicts the turbulent vertical heat flux by roughly a factor of 4 in the stably stratified region...

Creator:: Haack, Tracy, Chelton, Dudley, Pullen, Julie, Doyle, James D., and Schlax, Michael
Abstract:: High-resolution mesoscale model sea surface temperature (SST) analyses and surface wind stress forecasts off the U.S. West Coast are analyzed on monthly time scales for robust signatures of air–sea interaction as the surface winds encounter ocean surface features such as SST fronts, filaments, and eddies. This interaction is manifest by...

Creator:: Lerczak, James A., Geyer, W. Rockwell, and Chant, Robert J.
Abstract:: The subtidal salt balance and the mechanisms driving the downgradient salt flux in the Hudson River estuary are investigated using measurements from a cross-channel mooring array of current meters, temperature and conductivity sensors, and cross-channel and along-estuary shipboard surveys obtained during the spring of 2002. Steady (subtidal) vertical shear dispersion,...

Creator:: Lerczak, James A., Geyer, W. Rockwell, and Ralston, David K.
Abstract:: The temporal response of the length of a partially mixed estuary to changes in freshwater discharge Q𝒻 and tidal amplitude Uₜ is studied using a 108-day time series collected along the length of the Hudson River estuary in the spring and summer of 2004 and a long-term (13.4 yr) record...

Creator:: Scully, Malcolm E., Geyer, W. Rockwell, and Lerczak, James A.
Abstract:: In most estuarine systems it is assumed that the dominant along-channel momentum balance is between the integrated pressure gradient and bed stress. Scaling the amplitude of the estuarine circulation based on this balance has been shown to have predictive skill. However, a number of authors recently highlighted important nonlinear processes...

Creator:: Ralston, David K., Geyer, W. Rockwell, and Lerczak, James A.
Abstract:: A tidally and cross-sectionally averaged model based on the temporal evolution of the quasi-steady Hansen and Rattray equations is applied to simulate the salinity distribution and vertical exchange flow along the Hudson River estuary. The model achieves high skill at hindcasting salinity and residual velocity variation during a 110-day period...
