Geomagnetic and lithological controls on paleomagnetic secular variations in Holocene sediments from the Amundsen Sea, West Antarctica

Résumé fourni par la source

This dataset contains Holocene paleomagnetic data from three sediment cores (NBP19-02 KC15, NBP19-02 KC19, NBP20-02 KC33) collected from offshore Thwaites Glacier in the Amundsen Sea, West Antarctica. Sediment cores used in this study were recovered during 2019 and 2020 (cruises NBP19-02 and NBP20-02), aboard the RV/IB Nathaniel B. Palmer in the Amundsen Sea. This dataset contains the following files: Core metadata Foraminifera radiocarbon ages Acid insoluble organic matter (AIOM) ages Paleomagnetic data (NBP19-02 KC15, NBP19-02 KC19 and NBP20-02 KC33): Columns are defined as follows: Depth (cm): Core depth in cm Common stratigraphic depth (cm): Correlated depth (in reference to NBP19-02 KC15) in cm Age (cal. yrs BP): Calibrated radiocarbon age in years before present, assigned to core depths based on stratigraphic correlation Magnetic susceptibiliy: Bulk magnetic susceptibility Inclination (°): Inclination values from PCA results (UPmag; Xuan & Channell, 2009) using 10-65 mT demagnetization range Decliantion (°): Decliantion values from PCA results (UPmag; Xuan & Channell, 2009) using 10-65 mT demagnetization range MAD (°): Maximum angular deviation values from PCA results (UPmag; Xuan & Channell, 2009) using 10-65 mT demagnetization range kARM/k: Ratio of kARM to magnetic susceptibility RPI (10-65 mT): Relative paleointensity calculated via the UPmag slope fit method, using 10-65 mT demagnetization range (Xuan & Channell, 2009)
