Two Opposing Views: California coastal , waters are dominated by upwelling, therefore anthropogenic nutrients are not a primary driver ww� ,a - - Local anthropogenic inputs can exacerbate global drivers, potentially pushing DO and pH to ecological tipping-points OCSD Diversion : A unique opportunity to investigate an emerging issue • In situ field experiment not normally allowed • Comparison of conditions: • Offshore pipe turned off, then back on • Nearshore pipe turned on , then off ti OCSD Brought Together A Community of Researchers Modelers, Chemical Oceanographers, Physical Oceanographers, Biological Oceanographers, Roboticists, Computer scientists S C R I P P S I N S T I T U T 1 0 N O F OCEANOGRAPHY ` GLOBAL DISCOVERIES FOR (O M O,t O W'S WORLD Scripps Institution ......... of Oceanography Jet Propulsion Laboratory .o '. . •••.., University of --R California Inst. of Technology Southern California �,nl.1F0,R tFT LIG Ili ` `O J =� 7 UCLA r CeNCOOS University of California "" _ at Los Angeles University of California g at Santa Barbara • M B A B I Stanford University of California University at Santa Cruz Southern California Coastal Moss Landing Monterey Bay Aquarium Water Research Project Marine Labs Research Institute > N N V G � � rbr ti O / 0 y c �Z ■ ■ O c U/ 2 e e J O i � E O m ti N � d�o ZQ �jV � U >1 O � c/o06 O E O U O4-0 +� � O w Autonomous Underwater Vehicles : Surface Wave Glider (plume tracking & phytoplankton response) FPP ' - . .
