Antarctic diatom silicification diminishes under ocean acidification
Progress Code: completed Statement: No problems were encountered with data collection. The six level fCO2 gradient approach meant that our data could be analysed using a regression model, allowing us to identify functional relationships between our fCO2 treatment and our response variables.
