Mussel shell growth data

Mussel 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 experimental conditions for 9 months (n=4 per treatment) used for figure 4. Measurements for weight (g), height (mm), length (mm) and width (mm) of shell are provided for use of calculating STI. A higher shell thickness index indicates a thicker shell. Shells were grown at 380, 550, 750 and 1000 μatm CO2 at ambient temperature and 750 and 1000 μatm CO2 ambient temperature + 2°C, treatments were labelled as CO2 μatm and temperature in the spreadsheet.
