Antarctic Peninsula Sediment Magnetic Susceptibility from LARISSA Cruises

Magnetic susceptibility measurements from sediment cores collected during two Antarctic research cruises, NBP10-01 and NBP12-03, as part of the Larsen Ice Shelf System Antarctica (LARISSA) program. The data is curated by the Antarctic Marine Geology Research Facility at Florida State University. Measurements were taken onboard ship using Bartington MS2C loop sensors for jumbo piston cores and an MS2E surface scanning sensor for kasten core archive tubes.

Use Cases

• Correlating sediment layers across cores from Larsen Ice Shelf embayments (LIS-A, LIS-B) using magnetic susceptibility profiles.
• Analyzing temporal changes in sediment composition in western Peninsula fjords like Andvord Bay via susceptibility time-series.
• Comparing depositional environments between the eastern Larsen embayments and western fjords using core susceptibility data.
• Integrating susceptibility data with other core measurements to reconstruct past glacial and oceanographic conditions.

Strengths

• Data from two dedicated research cruises (NBP10-01, NBP12-03) under a coordinated program (LARISSA).
• Measurements use specialized, industry-standard Bartington sensors (MS2C and MS2E).
• Covers multiple distinct geographic areas on both eastern and western Antarctic Peninsula.

Limitations

• Exact sample size (number of cores, rows of data) is unknown.
• Data access requires a manual request process to the curator, not direct download.
• Specific temporal coverage within the cores (age depth model) is not detailed.
