Another assertion is that some generation is possible for most of the tidal cycle.

They emerge to the surface a few hours before low tide, although some individuals may remain submerged for the entire tidal cycle.

This study implies consequences for the species if global warming leads to an alteration of tidal cycles.

Bond events may also be correlated with the 1800-year lunar tidal cycle.

"They're sustained for six tidal cycles, while a hurricane is in and out in maybe 10 hours or less."

Tidal stage is also measured in degrees, with 360 per tidal cycle.

The Earth's rotation relative to this shape causes the daily tidal cycle.

While some generation is possible for most of the tidal cycle, in practice turbines lose efficiency at lower operating rates.

Now we have this large stretch of beach affected on two subsequent days, totaling at least four to six tidal cycles.

The 12.4-hour rhythm is not the only tidal cycle that marine life responds to.
