The influence of marine anoxia on precipitation of Mytilus galloprovincialis shell carbonate in the coastal zone of the Rovinj bay (Northern Adriatic)

The results of this study suggest shanges in shell growth structure and in the isotopic, as well as chemical composition of Mytilus galloprovincialis shells due to anoxia in the coastal zone of the Rovinj Bay, Northern Adriatic. The outer aragonitic "stress layer" of Mytilus galloprovincialis shells formed during pronounced summer anoxia due to intensive phytoplankton bloom in the years 1989-1991 is massive pink coloured and out of oxygen and carbon isotopic equilibria. It also exhibits higher C/O ratios relative to the uncoloured aragonitic layer precipitated by Mytilus galloprovincialis living in normal oxic conditions.
