When wind blows parallel to a long shoreline for a considerable period of time (for a steady state to develop), a dynamic balance is established between the wind stress on the …
WitrynaAbstract. The Intermittent Upwelling Hypothesis (IUH) posits that subsidies of larvae and phytoplankton to intertidal communities should vary unimodally along a gradient of upwelling from persistent upwelling to persistent downwelling with most subsidies occurring where upwel-ling is of intermediate strength and intermittent. WitrynaUpwelling occurs in the open ocean and along coastlines. The reverse process, called downwelling, also occurs when wind causes surface water to build up along a coastline. The surface water eventually …
