Mass-normalized magnetic susceptibility and rockmagnetic measurements from discrete subsamples of sediment cores collected during USAP cruises NBP10-01 and NBP12-03. The data were produced by the SCIOPS organization as part of the Larsen Ice Shelf System Antarctica (LARISSA) program. Study areas include the Larsen Ice Shelf embayments and several fjords and bays on the western Antarctic Peninsula.
Use Cases
- Correlating sediment layers across different core locations using mass-normalized magnetic susceptibility as a stratigraphic marker.
- Investigating past glacial and oceanographic conditions in Antarctic fjords by analyzing rockmagnetic measurement trends.
- Reconstructing depositional environments in the Larsen Ice Shelf region by comparing magnetic data from kasten cores, jumbo piston cores, and mega cores.
Strengths
- Data originates from two major USAP research cruises (NBP10-01 and NBP12-03), providing a multi-campaign perspective.
- Covers multiple distinct geographic features including ice shelf embayments, fjords, and a sediment drift.
Limitations
- Specific sample count, temporal coverage, and measurement precision are unknown.
- Lack of column definitions limits detailed analysis of individual magnetic parameters.
