Tides and tidal currents help mix cold arctic waters with warmer waters in the tropics.

There is the pleasant cunning of making the wind take us where we want to go, and there are charts to read, with their soundings and buoys and markers, and the tide tables, and the tidal current tables, and the tidal current charts, and knots and splices to learn.

After the powerful current of the East River — which is actually a tidal channel — damaged the rotors and broke off some of the original fiberglass and steel blades, the company earlier this month whittled its test bed down to two turbines with new aluminum — magnesium blades 16 feet (five meters) in diameter.

Balazs and his colleagues report in the current issue of the Marine Pollution Bulletin how 300 pellets a day were washing up on Kualoa Beach: «A general review of data for tidal cycles, moon phases, wind speed and direction, and surf conditions failed to identify any consistent correlation with the erratic fluctuations in daily faecal counts.»

A report in the journal Nature cites the discovery of a new planet, WASP - 18b, which challenges assumptions about tidal interactions — it's too close and orbiting too fast not to have collided with its star, according to current knowledge.

According to Doug Armstrong, Ocean Beach Patrol Supervisor, Ocean Beach's exposure to multiple swell directions coupled with its proximity to the tidal exchange at the mouth of the Golden Gate Strait make it subject to a tremendous amount of rip currents — and the rip currents change every day.

Predicting sea ice extent is easy if you can mentally calculate wind variations, momentum, sea currents, multi year ice compression ratios, tidal synergy with weather patterns, the AO, the temperature of ice sea water and air, how cloudy it will be, salinity, pycnocline convection rates, sea surface to air interface, CO2 exchange, ice thickness distributions.....

Tidal variability in more complex regional models that include sea ice, ice shelves, and ocean currents that vary with depth, is obtained by using global models to set tides at the regional model's open boundaries.

However the tidal currents coming into contact with the relief of the ocean bottom (even if this is very deep) creates waves which are propagated at the interface between two layers of different densities.

Most existing tidal currents devices have been based on horizontal axis propeller - type designs, much like wind turbines, mounted on fixed towers or on the sea - bed, sometimes with ducts to enhance the flow.

Features of the model described here include the following: (1) tripolar grid to resolve the Arctic Ocean without polar filtering, (2) partial bottom step representation of topography to better represent topographically influenced advective and wave processes, (3) more accurate equation of state, (4) three - dimensional flux limited tracer advection to reduce overshoots and undershoots, (5) incorporation of regional climatological variability in shortwave penetration, (6) neutral physics parameterization for representation of the pathways of tracer transport, (7) staggered time stepping for tracer conservation and numerical efficiency, (8) anisotropic horizontal viscosities for representation of equatorial currents, (9) parameterization of exchange with marginal seas, (10) incorporation of a free surface that accommodates a dynamic ice model and wave propagation, (11) transport of water across the ocean free surface to eliminate unphysical «virtual tracer flux» methods, (12) parameterization of tidal mixing on continental shelves.
