The difference between the two scenarios is that in the Keys, the fish are orienting around deep ocean currents, and off Tampa, it's a wind-driven current
on the Florida shelf.
According to this, the wind-driven current
is deflected with an angle [theta] to the right (clockwise) from the wind direction (for the Northern Hemisphere).
Visible from space and four times more powerful than the Gulf Stream, this wind-driven current
circles Antarctica, separating the warmer waters of the subtropics from the polar waters around the continent, and reaching all the way from the surface to the ocean floor--five kilometres below.
We did a study regarding the variation of wind-driven current
with the sea level and, for the same level, with the depth.
Caption: Even on smaller waters, deciphering wind-driven currents
can be key to locating hungry pike.
Whilst the currents in continental shelf seas, like the Irish Sea and North Sea, are dominated by the tide, there is evidence that much weaker wind-driven currents
might be responsible for circulating key nutrients within the seas.
Geological Survey says the low oxygen levels may result from wind-driven currents
A new study suggests that these enigmatic waters expand when their permafrost banks melt, rather than when wind-driven currents
cause erosion, as scientists had proposed for decades.
Case studies include examples of wind-driven currents
, fast-changing ecosystems under human pressure, transboundary management, and sustainable use and development.
For example, the role of wind-driven changes includes a review of how local wind-driven currents
along a coast can, via the action of the Coriolis force, change coastal sea level, but does not describe how some wind-driven effects can propagate along continental boundaries as coastally trapped waves.
WHOI Senior Scientist and biological oceanographer Cheryl Ann Butman showed that wind-driven currents
controlled the onshore and offshore transport of clam, snail, and worm larvae.
