Simulating oceanic CaCO3 export production in the greenhouse
[6] For studying the effect of CO 2 buffering on ocean pH and biogenic calcite production we employ here the biogeochemical ocean general circulation model HAMOCC [Maier-Reimer, 1993] in its version HAMOCC4 [Six and Maier-Reimer, 1996; Hofmann et al., 2000].The model covers the globe with a horizontal resolution of 3.5 × …

mp-3953: CaCO3 (trigonal, R-3c, 167)
CaCO3 is Calcite structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent O2- atoms to form corner-sharing CaO6 octahedra. The corner-sharing octahedral tilt angles are 62°. All Ca–O bond lengths are 2.39 Å. C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms.

The results for the relative changes in CaCO 3 production remained similar, though the negative feedback on the atmospheric pCO 2 doubled. This negative feedback due to a weakening of the CaCO 3 production, however, was small and resulted in a decrease of the atmospheric pCO 2 of only 10 ppm (for A = 0.15) or 20 ppm (for A = …
