Changes in Coastal Upwelling Linked to Variability in Marine Ecosystem Off

AUSTIN, Texas — In findings of relevance to conservationists and the
fishing industry, new research links short-term reductions in growth and
reproduction of marine animals off the California coast to increasing
variability in the strength of coastal upwelling currents — currents that
supply nutrients to the region's diverse ecosystem.

Along the west coast of North America, winds lift deep, nutrient-rich water
into sunlit surface layers, fueling vast phytoplankton blooms that
ultimately support fish, seabirds and marine mammals.
