However, both observations and isotope modelling results indicate that temperature is the primary control on 18O in the study region (Supplementary Information).

Suggest changing isotope interpretation 1 to "P_isotope" and making isotope interpretation 2 = "postdepositional processes", TO: I changed isotope interpretation 1, but omitted postdeposional processes as isotope interpretation 2 as this is true for all records and archives
