Some samples are potentially biased since they are beyond the lower limit of the temperature gradient (5.0-18.4 °C) covered by the calibration data set

"Secret Lake and other lakes in the region appear biased towards summer and autumn d18O of precipitation values"; "Due to the possible overprinting effects of enhanced evaporation and reduced sea ice in Baffin Bay (and thus a closer moisture source) during the HTM, the estimated anomaly of 2.5-4 °C between 7.7 and 4 ka is likely an upper limit"; ", "we view these estimates as upper bounds on the amplitude of past summer-biased temperature changes"
