Relative paleointensity and environmental magnetics for IODP Site 303-U1307

Relative paleointensity (RPI; NRM/ARM) for the 20-50 mT demagnetization interval, magnetic susceptibility (κ) and magnetic grain size (κARM/κ) u-channel data, measured every centimetre between ~117 and 158 revised metres composite depth (rMCD) at IODP ...

Paleomagnetic Secular Variation Records From the Post‐Glacial Tahiti Coral Reef

Earth and Space Science
IODP Expedition 310 recovered more than 600 m of Post Last‐Glacial‐Maximum (LGM) coral reef framework rocks from the current reef tract surrounding the island of Tahiti. Six sites (12 holes) were sampled for paleomagnetic studies on the south side of the

Paleomagnetic Secular Variations in North Greenland Around 81°N Over the Last 6,000 Years

Geochemistry, Geophysics, Geosystems
We investigate full vector paleomagnetic changes recorded in high‐resolution sediments of Petermann Fjord, North Greenland, deposited over the last 6 kyr, in the context of the recent rapid changes in the geomagnetic field.

Removing Climatic Overprints in Sedimentary Cosmogenic Beryllium Records: Potentials and Limits

Geochemistry, Geophysics, Geosystems
Continuous reconstructions of past variations of the Earth's magnetic field are based mainly on paleomagnetic and cosmogenic 10Be records in marine sediments. In both cases, the recording mechanisms can be affected by environmental processes.

Variations of the geomagnetic field during the Holocene: Relative paleointensity and inclination record from the West Pacific (ODP Hole 1202B)

, 2006
We conducted detailed rock magnetic investigations on 36m of drill core collected during Ocean Drilling Program Leg 195 at Hole 1202B (24◦48.24 N, 122◦30.00 E), in the Southern Okinawa Trough, with the goal of extracting a reliable paleointensity signal

Paleomagnetic and oxygen isotopic records from the upper Pliocene marine succession in the Western North Pacific: insights into the Mammoth and Kaena subchrons

Progress in Earth and Planetary Science
Robust chronological frameworks that integrate paleomagnetic and oxygen isotope records are essential to stratigraphic correlation across diverse geological records. However, such records remain scarce for the Late Pliocene.
