Rio Beni Floodplain Sediment Cores with Grain Size and Sedimentation Rates, 2011-2013

British Geological Survey data from sediment cores collected from the Rio Beni floodplain in 2011, 2012, and 2013. The dataset includes measurements of core depth, grain size characteristics (clay, silt, sand percentages), sedimentation rate, and sediment age determined from Pb-210 activity. Each row represents a sediment core with 12 columns of data, including location coordinates and core collection year.

Use Cases

• Modeling floodplain sedimentation rates based on Pb-210-derived age data
• Analyzing spatial patterns of grain size distribution (clay, silt, sand) across the floodplain
• Correlating sediment age with depth for geochronological studies
• Mapping sediment core characteristics by their geospatial coordinates

Strengths

• Data spans three collection years (2011, 2012, 2013), providing temporal context
• Includes 12 specific measurement types per core, such as location, age, grain size percentages, and density
• Based on published laboratory techniques and analysis procedures (Aalto & Nittrouer, 2012)

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
