We investigate the processes that influence residence time in a partially mixed estuary using a threedimensional circulation model. The complex geometry of the study region is not optimal for a structured grid model and so we developed a new method of grid connectivity. This involves a novel approach that allows an unlimited number of individual grids to be combined in an efficient manner to pr...

Tides in fluvial estuaries are distorted by non-stationary river discharge, which makes the analysis of estuarine water levels less accurate when using conventional tidal method. As a powerful and widely-used method for nonlinear time series, application Variational Mode Decomposition (VMD) to tides is nonexistent. This paper aims illustrate verify suitability VMD as new tool tides. The efficie...

The distribution of eccentricities e of extrasolar planets with semimajor axes a > 0:2 AU is very uniform, and values for e are relatively large, averaging 0.3 and broadly distributed up to near 1. For a < 0:2 AU, eccentricities are much smaller (most e < 0:2), a characteristic widely attributed to damping by tides after the planets formed and the protoplanetary gas disk dissipated.Most previou...

Atmospheric densities derived from measured acceleration of several Mars orbiters reveal large amplitude Sun-synchronous longitudinal density variations at altitudes of about 100-160km (see Figure 1). These variations are associated with vertically-propagating nonmigrating solar thermal tides that are excited near Mars’ surface and propagate into the thermosphere. Excitation of these waves is a...

Many intertidal and shallow water crabs have strong reproductive cycles and migratory larvae. Females release larvae near the time of high water of the larger amplitude nocturnal tides during the semilunar or lunar cycles. Newly hatched larvae move quickly at night toward and into the sea where, weeks later, they develop to megalopae that then ride nocturnal flood tides inshore and up estuaries...

Three experiments were carried out in 300 l mesocosms using natural seawater from the Peconic Bays ecosystem, Long Island, New York, to examine the ability of the northern quahog Mercenaria mercenaria to prevent blooms of the brown tide alga Aureococcus anophagefferens. Nutrient enrichment and mixing of the mesocosms was conducted according to previous methods that we have employed to induce br...

Mode-1 internal tides were observed the western North Atlantic using an ocean acoustic tomography array deployed in 1991–1992 centered on 251N, 661W. The pentagonal array, 700-km across, acted as an antenna for mode-1 internal-tides. Coherent internal-tide waves with O(1m) displacements were observed traveling in several directions. Although the internal tides of the region were relatively quie...

Especially in aquatic habitats, hypoxia can be an important evolutionary driving force resulting in both convergent and divergent physiological strategies for hypoxic survival. Examining adaptations to anoxic/hypoxic survival in hypoxia-tolerant animals may offer fresh ideas for the treatment of hypoxia-related diseases. Here, we summarise our present knowledge of two fishes that have evolved t...

A three-dimensional Regional Ocean Modelling System is used to study the tidal characteristics and their dynamics in the Sunda Shelf of the southern South China Sea. In this model, the outer domain is set with a 25 km resolution and the inner one, with a 9 km resolution. Calculations are performed on the inner domain. The model is forced at the sea surface by climatological monthly mean wind st...

The Gerstenkorn-MacDonald-Kaula theory of bodily tides assumes constancy of the geometric lag angle δ , while the Singer-Mignard theory asserts constancy of the time lag ∆t . Each of these two models is tacitly based on a particular law of the geometric lag’s dependence upon the main frequency χ of the tidal flexure. In the theory of Gerstenkorn (1955), MacDonald (1964), and Kaula (1964) δ ∼ χ0...
