Tidal-Trophic Events

B130901_03VER_WIF1_41974

When strong tides rip through topographically complex coastal habitats, areas of particularly turbulent jets can become hotspots for feeding frenzies. Fish and marine tetrapods gather in tidally dynamics passages in diverse and energetic assemblages to exploit the planktonic production that has been aggregated there. The trophic explosion that results is a thrill to witness firsthand and a challenge to document scientifically. This Backgrounder briefly outlines the seabird and marine mammal literature that addresses these tidal and topographic trophic events.

More details on the processes and importance of such tidal processes has already been explored in the “Fjords!” and “Plankton Processes” backgrounders, available on the Reports page. This document merely caps them with some information on how higher trophic levels swoop in and chomp it.
