** pertco2.R - R routine to compute coefficients for the standard 
perturbation approach but using an average Med Sea alkalinity (2529.8 
ueq/kg) instead of the global ocean average alkalinity (2300 ueq/kg). 
The MED simulation uses these coefficients (in coeffs.dat).

** coeffs.dat - coefficients computed with pertco2.R

** pertco2_salt.R - R routine to compute coefficients for the modified 
perturbation approach where Med Sea alkalinity is variable as a function 
of salinity. The VAR simulation uses these coefficients (in 
coeffs_salt.dat and Zcoef.dat).

** coeffs_salt.dat - coefficients computed with pertco2_salt.R

** Zcoef.txt - same coefficients as in coeffs_salt.dat, but arranged 
more conveniently (as in Table 6 in the main manuscript).
