aErrors are in 1s; n = 494 for all Looe Key equations except the maximum/minimum (max/min) regression is n = 83. Reduced major axis (RMA) and ordinary least squares (OLS) equations are provided for comparison along with literature values. SE denotes standard error. Equations are in the form (dc  – dw)  = mSST + b and Sr/Ca = mSST + b.
