17 p, 7.3 MB The devil's in the disequilibrium : sensitivity of ocean carbon storage to climate state and iron fertilization in a general circulation model / Eggleston, Sarah (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Galbraith, Eric D. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Ocean dissolved inorganic carbon (DIC) storage can be conceptualized as the sum of four components: saturation (DICsat), disequilibrium (DICdis), carbonate (DICcarb) and soft tissue (DICsoft). Among these, DICdis and DICsoft have the potential for large changes that are relatively difficult to predict. [...]

Planktic foraminifera were collected with 150 µm BONGO nets from the upper 200 m water depth at 20 stations across the Mediterranean Sea between 2 May and 2 June 2013. The main aim is to characterize the species distribution and test the covariance between foraminiferal area density (ρA) and seawater carbonate chemistry in a biogeochemical gradient including ultraoligotrophic conditions.
