Gallo was right when he talked about that compression would destroy the “rings.” I believe some courting of ice cores is completed via a O16/O14 ratio, but I am unsure. That ratio could also be good solely Wapa singles to point the local weather at the time of snowfall. The age fashions making use of the alignment of Ti/Ca to speleothem isotopic records have been validated by evaluating the radiocarbon-dated upper portion of the cores with the U-Th dated speleothem sign (Supplementary Fig. 3). This validation was the initial step that led to the usage of speleothem isotopic information to complement the relationship of the three cores from the Brazilian margin because it demonstrates that terrigenous input at these sites is coeval with the precipitation occasions recorded within the speleothems25.
