image: This is a cartoon of the wind intensification/upwelling process. Increasing winds and upwelling may increase nutrients in the lighted upper ocean, enhancing primary productivity, but excessive upwelling may increase turbulence, acidification and de-oxygenation of the photic zone. The ecological impacts of upwelling intensification are difficult to predict. This image relates to a paper that appeared in the July 4, 2014, issue of Science, published by AAAS. The paper, by William Sydeman at the Farallon Institute for Advanced Ecosystem Research in Petaluma, Calif., and colleagues was titled, "Climate change and wind intensification in coastal upwelling ecosystems." view more
