Rare Earth Element Dynamics in a German High-Energy Beach Subsurface

Spiekeroog Island, Germany, is the location for this study of rare earth element dynamics in the deep subsurface of a high-energy beach. The dataset is based on porewater and sediment samples collected to a depth of 24 meters below ground surface along a cross-shore transect, and includes results from a flow-through reactor experiment. It was authored by Magali Roberts and last updated on 2026-04-21.

Use Cases

• Modeling conservative mixing of seawater and freshwater based on rare earth element concentrations.
• Investigating trace element scavenging and redox transformations based on porewater chemistry.
• Analyzing the influence of iron-oxide reduction and organic carbon remineralization on element dynamics.
• Studying the accumulation and release of anthropogenic gadolinium under changing redox conditions.

Strengths

• Data includes samples from a depth of 24 meters below ground surface, providing a deep subsurface profile.
• Includes results from a controlled flow-through reactor experiment to observe redox gradients.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Dataset size is 405.4 KB, indicating a very limited scope and likely small sample count.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
