Summary of SIMS analyses of oxygen isotope ratios measured at WiscSIMS on the Nautilus macromphalus (AMNH 105621) and confocal microscope brightness.

These are ion microprobe analyses of oxygen isotope ratios, grey scale values from confocal laser fluorescence images, and distance perpendicular to banding for analyses that were shown to be regular based on pit morphology. See supplementary material for a complete list of measurements.
