      Oceanic and coastal waters are acidifying due to processes dominated in the open ocean by increasing atmospheric CO2 and dominated in estuaries and some coastal waters by nutrient-fueled respiration. The patterns and ...
    • Animating the carbon cycle 

      Schmitz, Oswald J.; Raymond, Peter A.; Estes, James A.; Kurz, Werner A.; Holtgrieve, Gordon W.; Ritchie, Mark E.; Schindler, Daniel E.; Spivak, Amanda C.; Wilson, Rod W.; Bradford, Mark A.; Christensen, Villy; Deegan, Linda A.; Smetacek, Victor; Vanni, Michael J.; Wilmers, Christopher C. (2013-08)
      Understanding the biogeochemical processes regulating carbon cycling is central to mitigating atmospheric CO2 emissions. The role of living organisms has been accounted for, but the focus has traditionally been on ...
    • Anisotropic material transport by eddies and eddy-driven currents in a model of the North Atlantic
