Florida Bay Sediment Radium-226 Activity Measurements

Radium-226 activity measurements from sediment cores in Florida Bay, used for geochronological dating. The dataset includes core number, depth, activity, and measurement error, collected by the CEOS_EXTRA organization. Data was last updated in June 1997.

Use Cases

• Calculate sediment accumulation rates from depth profiles of Ra-226 activity.
• Calibrate geochronological models using the known half-life of Ra-226.
• Analyze spatial variability in sedimentation by comparing Ra-226 activity across different core numbers.
• Estimate measurement uncertainty in sediment dating by incorporating the provided Ra-226 error values.

Strengths

• Data includes specific measurement error (Ra-226 error) for quality assessment.
• Focuses on a single, well-understood radionuclide (Ra-226) with a known half-life for dating.

Limitations

• Dataset is temporally stale, with no updates since 1997.
• Unknown sample size (row count) and geographic coverage beyond Florida Bay.
