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

Element contents and isotope composition of sediments and basalts from DSDP Site 78-543
Twenty-four piston core sediment samples and 13 sediments and 3 basalts from DSDP Leg 78 Site 543 were analyzed for Sr, Nd and Pb isotopic compositions. The results show sediment with highly radiogeni
