Sirenian Enamel d 13 C and d 18 O Values: Differences with Latitude and Age
1
Sirenian Enamel d 13 C and d 18 O Values: Differences with Latitude and Age Carbon Isotope Values • Paleogene – No significant difference detected between low and high latitudes • Neogene – Significant difference with latitude; may indicate increase in marine-freshwater mixing or changes in seawater DIC d 13 C values Oxygen Isotope Values • Paleogene & Neogene – Significant difference detected between low and high latitudes • Neogene – The magnitude of offset between low and high latitudes greater than that for the Paleogene Mark T.

Carbon Isotope Values• Paleogene – No significant difference detected between low and high latitudes • Neogene – Significant difference with latitude; may indicate increase in marine-freshwater mixing or changes in seawater DIC d13C values
Oxygen Isotope Values• Paleogene & Neogene – Significant difference detected between low and high latitudes
• Neogene – The magnitude of offset between low and high latitudes greater than that for the Paleogene
