Anisotropy of magnetic susceptibility (AMS) data from sediment samples collected at IODP Site U1391 in the Southwest Iberian Margin of the North Atlantic Ocean. The dataset includes depth, estimated age, and AMS parameters such as declination and anisotropy factors. Data were organized by the British Geological Survey and published in a 2020 research article.
Use Cases
- Analyze the relationship between sediment depth and AMS parameters like Pj and T to study depositional processes.
- Model paleoenvironmental changes using the estimated age column alongside magnetic susceptibility factors q and declination.
- Correlate orientation-corrected K1 declination with other AMS factors to investigate sediment fabric anisotropy.
Strengths
- Data originates from a specific, documented scientific drilling site (IODP Site U1391).
- Includes multiple calculated AMS parameters (Pj, q, T, declination) for analysis.
- Linked to a peer-reviewed publication (DOI: 10.1029/2020PA003947) providing methodological context.
Limitations
- Sample size and total row count are unknown, limiting statistical assessment.
- Data scope is geographically restricted to a single site in the Southwest Iberian Margin.
