cross-checking the annual d18O variation against the annual dense bands counted from the positive X-rays as well as setting the lowest d18O value in a given year equal to November
VG Micromass 602E mass spectrometer upgraded with SIRA series electronics
; climateInterpretation_seasonality changed - was originally subannual; archiveType changed - was originally Coral (CO)
At decadal time scale the d18O signal is only influenced by d18Osw (Salinity and precipitation), NO influence of Temperature
