About 10 to 15 specimens were selected from each 1cm sample. Each shell was cracked open and sonicated in methanol to remove degreesnegrained particles that degreesll the chambers. Cleaned shell fragments were treated with 15% H2O2 for 1 hour to remove organic matter, dried, and ground to a homogenous powder.

The d18O record from Chichancanab generally supports our E/P inferences based on the S record

210Pb, 239+240Pu or 137Cs activity uncertainty

Y if supported 210Pb activity, N if unsupported 210Pb activity

model used to convert 210Pb activity to age (e.g., constant rate of supply)

years before 1950 (calibrated age, or ages that dont need calibration)
