Abstract:
Magnetic susceptibility and natural remanent magnetization (NRM) data from discrete samples from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). The offshore phase of this expedition took place between 2023-08-31 and 2023-10-31 onboard multipurpose vessel MMA Valour sailing from and to Barbers Point Harbor, Hawai'i, USA, followed by the onshore phase from 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. Discrete samples (2.54 cm diameter minicores, drilled perpendicular to the split face of the core sections) for standard paleomagnetic and magnetic susceptibility measurements were taken from the work halves of core sections during the onshore phase of the expedition. Measurements were performed in the Paleomagnetism Laboratory of the Department of Geosciences, University of Bremen using an AGICO KLY Kappabridge for magnetic susceptibility measurements and a 2G-Enterprises horizontal pass-through superconducting rock magnetometer (SRM 755) for NRM measurements.
