The study conducted at the University of Texas has studied the short-term reductions in the marine animal growth and reproduction. According to the study, the shrinking has a link with higher variability along stronger coastal upwelling currents. These currents provide essential nutrients to several ecosystems.
The study stated that nutrient-rich water of the sea is pulled and brought to shallow water by west coast winds of Pacific coast of North America. The process allows phytoplankton, autotrophic components of the plankton community, to bloom, which is a source of food for coastal animals and birds.
