Florida Bay Sediment Core Physical and Radioisotope Data

Sediment cores from Florida Bay provide measurements of bulk density, water content, particle size distribution, and lead-210 activity for radioactive dating. The dataset was compiled by the CEOS_EXTRA organization and last updated in June 1997. It enables analysis of sediment composition and accumulation rates over time.

Use Cases

• Calculate sediment accumulation rates using total Pb-210 activity and its decay half-life.
• Analyze sediment compaction and composition changes with depth using wet bulk density, dry bulk density, and % H2O content columns.
• Model particle size distribution through the sediment column using the coarse (% dry wt.) > 0.062 mm and fines (% dry wt.) < 0.062 mm features.
• Estimate organic matter content via the % loss on ignition measurement across core samples.

Strengths

• Includes specific radioisotope measurements (total Pb-210 activity with error) for geochronology.
• Provides multiple related physical properties (density, water content, particle size) per core sample.

Limitations

• Data is temporally stale, with a last update in 1997.
• Sample size, row count, and geographic coverage within Florida Bay are unknown.
• Unknown if the dataset includes metadata for core locations and sampling dates.
