Rare Earth Element Dynamics in a High-Energy Beach Subsurface, Spiekeroog Island

Porewater and sediment data from a deep subsurface study of a subterranean estuary on Spiekeroog Island, Germany. The dataset includes samples collected to a depth of 24 meters below ground surface along a cross-shore transect, and 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 linked to iron-oxide reduction.
• Analyzing anthropogenic gadolinium accumulation and release under iron-reducing conditions.
• Studying the influence of particulate organic carbon remineralization on rare earth element dynamics.

Strengths

• Samples collected to a depth of 24 meters below ground surface, providing deep subsurface coverage.
• Includes a controlled flow-through reactor experiment to observe rare earth element behavior along an oxic-anoxic gradient.
• Focuses on a specific, dynamic high-energy beach system on Spiekeroog Island, southern North Sea.

Limitations

• Dataset size is 997.2 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.
