Svalbard Lake Sediment Core Data Capturing 6,700 Years of Arctic Cold Season Climate

6.7 ka of Arctic cold season climate proxy data from core STU-P1 in Svalbard Lake sediments. The dataset integrates hyperspectral imagery with X-Ray Fluorescence and Computed Tomography core scanning to characterize siderite concretions formed under lingering lake ice. It was produced by author van der Bilt for a publication available as a pre-print.

Use Cases

• Reconstructing past Arctic winter temperature trends based on siderite concretion formation linked to severe winters.
• Analyzing non-linear climate transitions based on the interplay of volcanic and cyclic paleoclimate forcings.
• Calibrating or validating climate models using a high-resolution, cold-season-specific paleoclimate record.
• Developing novel paleoclimate proxy methods by integrating hyperspectral imagery with geochemical core scanning data.

Strengths

• Covers a 6.7 ka (6,700-year) time span of Arctic climate history.
• Employs a novel, high micrometer-scale precision methodology integrating hyperspectral imagery, XRF, and CT scanning.
• Addresses a specific gap by focusing on cold-season climate proxies, contrasting with most records of growing-season conditions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• Data is associated with a pre-print publication, so the final published context may differ.
