Seafloor Sediment Cores from Former Larsen Ice Shelf Region

Bottom samples from the Northwest Weddell Sea region, including areas formerly occupied by the Larsen-A and Larsen-B ice shelves. The data comprises physical sediment cores, grab samples, and X-radiographs collected during three United States Antarctic Program research cruises. The Antarctic Marine Geology Research Facility at Florida State University curates the materials.

Use Cases

• Analyze sediment core layers from Kasten cores to reconstruct historical climate events.
• Study X-radiograph images of archive trays to assess sediment density and structure.
• Compare jumbo piston core samples from the LIS-B embayment and Vega Drift for geological variation.
• Examine Smith-MacIntyre surface grab samples for recent seafloor composition.
• Investigate dredged material from Jun Jaegyu Seamount for geological feature analysis.

Strengths

• Samples collected from three distinct research cruises (LMG04-04, LMG05-02, NBP06-03).
• Includes multiple sample types: 1-3 meter Kasten cores, jumbo piston cores, grab samples, and X-radiographs.

Limitations

• Exact sample counts, row numbers, and digital data availability are unknown.
• Temporal coverage and specific collection dates for the samples are not provided.
