Characteristic remanent magnetization (ChRM) directions of discrete samples from 28 m sediment cores showed two magnetic reversals that corresponds to polarity chrons C5Dr.1n/C5Dr.1r/C5Dn and an excursion during C5Dn chron. Relative paleointensity (RPI) data indicated fluctuations before the transitions, and the Earth’s field increased after the transitions. Isothermal remanent magnetization (IRM) and S-ratio measurements showed low-coercivity minerals in the samples. Anisotropy of magnetic susceptibility (AMS) data showed horizontal bedding, and deformation on some sediment cores due to drilling. Susceptibility (k) values were measured. X-ray fluorescence (XRF) analyses supported the stratigraphical correlation of the sediment with the prior works with sediment from nearby locations. Further investigation will focus on magnetic transition zones and detailed rock magnetism measurements.
