Maggie had no time to answer, for a new tidal current
swept along the line of the houses, and drove both the boats out on to the wide water, with a force that carried them far past the meeting current of the river.
The tidal current
runs to and fro in its unceasing service, crowded with memories of men and ships it had borne to the rest of home or to the battles of the sea.
If tidal currents
contained that much energy, the economics would be quite stellar and entirely worthy of his final exclamation mark.
The predicted of tidal current
can be more difficult by their sensitivity to bathymetry and landmasses.
However, Pakistan has yet to move in this direction, despite having various strategic locations with high tidal current
velocities or strong ocean currents along its 990km coastline.
They have published tidal current
tables for use by mariners since 1890.
In the local coastal areas, the surge current becomes unidirectional at some places where the tidal current
is usually rectilinear in each depth.
RWE Innogy and Voith Hydro, a subsidiary of RWE AG (RWE.XE), is installing a one-megawatt marine tidal current
turbine off the Scottish coast through joint venture Voith Hydro Ocean Current Technologies.
When flatfishes use selective tidal stream transport, the timing of vertical excursions away from the bottom can be combined with predictions of tidal current
velocity to construct hypothetical migration trajectories (Arnold and Holford, 1995).
Atlantis Resources is an international developer of tidal current
turbines, with offices in London, Sidney and Singapore.
As metrics of the potential tidal current
contribution to polynya dynamics, we create maps of the tidal currents
(U), the tidal mixing parameter h/[U.sup.3] (Simpson and Hunter, 1974; where h is the water depth), and the vertical excursion associated with the tidal currents
that drive water upslope and downslope over a tidal period.
Other topics include the effects of tidal current
on the movement patterns of juvenile sharks, the role of sharks in trophic dynamics, cues stimulating migrations, and organochlorine contaminants in sandbar and blacktip sharks.
