| Summary: | Ocean acidification threatens organisms that produce calcium carbonate shells by potentially generating an under-saturated carbonate environment. Resultant reduced calcification and growth, and subsequent dissolution of exoskeletons, would raise concerns over the ability of the shell to provide protection for the marine organism under ocean acidification and increased temperatures. We examined the impact of combined ocean acidification and temperature increase on shell formation of the economically important edible mussel Mytilus edulis. Shell growth and thickness along with a shell thickness index and shape analysis were determined. The ability of M. edulis to produce a functional protective shell after 9 months of experimental culture under ocean acidification and increasing temperatures (380, 550, 750, 1000 μatm pCO2, and 750, 1000 μatm pCO2 + 2°C) was assessed. Mussel shells grown under ocean acidification conditions displayed significant reductions in shell aragonite thickness, shell thickness index, ... : Mussel shell growth dataMussel shell growth data for figures 2, 3 and 4. The first worksheet entitled 'Mussel shell growth' lists all growth measurements for individual mussel shells used for mussel shell growth (mean ± SD) during 9 months of experimental culture (n=4 per treatment) used for figure 2. Shells were grown at 380, 550, 750 and 1000 μatm CO2 at ambient temperature and 750 and 1000 μatm CO2 ambient temperature + 2°C. The second worksheet entitled 'Aragonite_Calcite thickness' list all shell aragonite and calcite thickness measurements for individual mussels to calculate mussel shell calcite and aragonite in new growth (mean ± SD) (n=4 per treatment) used for figure 3. Aragonite and calcite in mm and the ratio of aragonite/ calcite. Shells were grown at 380, 550, 750 and 1000 μatm CO2 at ambient temperature and 750 and 1000 μatm CO2 ambient temperature + 2°C. The third worksheet entitled 'STI' lists all measurements taken to calculate Shell Thickness Index (STI) for mussel shells grown under ... |
