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...

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...

Creator:: Chen, Shih-Nan, Geyer, W. Rockwell, Ralston, David K., and Lerczak, James A.
Abstract:: Isohaline coordinate analysis is used to compare the exchange flow in two contrasting estuaries, the long (with respect to tidal excursion) Hudson River and the short Merrimack River, using validated numerical models. The isohaline analysis averages fluxes in salinity space rather than in physical space, yielding the isohaline exchange flow...

Creator:: Jurisa, Joseph T. and Chant, Robert J.
Abstract:: Idealized numerical simulations utilizing the Regional Ocean Modeling System (ROMS) are carried out to examine the response of buoyant river plume systems to offshore-directed wind stresses. It is found that after a few inertial periods of wind forcing the plume becomes detached from the coast and reaches a steady state...

Abstract:: A 3°N to 3°S transect of the equator at 140°15'W was made in November 1984. Vertical profiles of temperature, conductivity and turbulent dissipation were obtained at approximately 1 km intervals. Contrary to previous results, we found no obvious peak in dissipation either at the equator or clearly associated with the...

Abstract:: The effects of wind-forced upwelling and downwelling on the continental shelf off Duck, North Carolina, are studied through experiments with a two-dimensional numerical primitive equation model. Moored and shipboard measurements obtained during August–November 1994 as part of the Coastal Ocean Processes (CoOP) Inner Shelf Study (ISS) are used for model–data...

Creator:: Dillon, T. M., Moum, J. N., Chereskin, T. K., and Caldwell, D. R.
Abstract:: The conventional view of equatorial dynamics requires that the zonal equatorial wind stress be balanced, in the mean, by the vertical integral of “large-scale” terms, such as the zonal pressure gradient, mesoscale eddy flux, and mean advection, over the upper few hundred meters. It is usually presumed that the surface...

Creator:: Moum, J. N. and Osborn, T. R.
Abstract:: A series of profiles of velocity microstructure along 152°E in the western North Pacific Ocean were collected in May–June 1982. Large, averaged turbulent dissipation rates, ϵ, found in the main thermocline (400 to 1000 m) were determined by a combination of large independent estimates of ϵ and a greater rate...

Abstract:: Measurements of a fresh surface anomaly (fresh lens) produced by rainfall during a westerly wind burst have been analyzed. The measurements were made in December 1992 as part of the Coupled Ocean–Atmosphere Response Experiment in the western equatorial Pacific (2°S, 156°E). Measurements included radar estimates of rainfall, upper-ocean temperature (T),...

Abstract:: In this article the authors examine the kinematics and dynamics of the seasonal cycle in the western Indian Ocean in an eddy-permitting global simulation [Parallel Ocean Circulation Model, model run 4C (POCM-4C)]. Seasonal changes of the transport of the Agulhas Current are linked to the large-scale circulation in the tropical...
