Researchers debate what happens to key sources of food during strong upwelling currents. As we learned in class, a strong upwelling can carry larvae from organisms like barnacles from their offshore home out to sea where they would die.
New Research shows that barnacles, a key food source in fact thrive in strong upwellings. When a strong upwelling is present the barnacle larvae is more likely to be recruited to the rocky walls. When this happens the predators of the barnacles, like hogfish and whelks flock to these strong upwelling zones creating dynamic ecosystems where there were thought to be none.
Several studies have shown that strong upwelling zones aren't good environments for barnacles to live and have shown this before. The new research was done in deeper waters and the research was done by one of the only teams to be working in these waters in the Galapagos Islands.
