Antarctic Peninsula Sediment Cores from Larsen Ice Shelf Program

Physical sediment core samples collected from USAP research cruises NBP10-01 and NBP12-03. The collection includes kasten core archive tubes, jumbo piston core sections, and mega core archive cores. It was gathered by the Larsen Ice Shelf System Antarctica (LARISSA) program, organized by SCIOPS.

Use Cases

• Analyzing sediment layers from kasten cores to reconstruct past climate conditions.
• Correlating geological events across different sites like Andvord Bay and Barilari Bay using core sections.
• Studying ice shelf history and marine sedimentation patterns in the Larsen Ice Shelf embayments (LIS-A, LIS-B).
• Investigating sediment composition and deposition in fjord systems versus open-channel drifts like the Larsen Channel.

Strengths

• Collection includes multiple core types (kasten, jumbo piston, mega core) for varied analysis.
• Samples cover distinct geographic areas including eastern and western Antarctic Peninsula sites.

Limitations

• Physical sample access requires logistical coordination, limiting immediate data availability.
• Specific sample counts, depths, and analytical measurements for each core are not provided in the description.
