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. WitrynaAbout this Lecture. Lecture. In this module, we think about the vertical movement of water in the oceans, focusing on: (i) how surface wind stress and the Coriolis force can interact to produce the downwards motion of water (downwelling), including a tank experiment to demonstrate this process; (ii) how these same forces can produce upwards motion …
