Oxygen Isotope Data from Cultured Planktic Foraminifera

Micron-scale intrashell oxygen isotope measurements from the cultured planktic foraminifer species Orbulina universa. The data, archived by NOAA's National Centers for Environmental Information, covers parameters of paleoceanography for the Eastern Pacific Ocean. The temporal coverage is in calendar years before present, though specific begin and end dates are unavailable in the provided metadata.

Use Cases

• Calibrating the relationship between seawater temperature and oxygen isotope ratios (δ¹⁸O) in foraminiferal calcite using controlled culture data.
• Analyzing intrashell isotopic variability to understand growth and calcification dynamics in Orbulina universa.
• Reconstructing past sea surface conditions for the Eastern Pacific Ocean by applying proxy relationships derived from this cultured specimen data.

Strengths

• Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides high-resolution micron-scale measurements within individual foraminifer shells.

Limitations

• Specific temporal coverage (begin and end dates) is listed as unavailable in the description.
• Geographic coverage is limited to the Eastern Pacific Ocean, which may limit global applicability.
• Sample size (number of specimens or measurements) is unknown.
