Investigations of the behavior of the geomagnetic field on geological timescales rely on globally
distributed data sets from dated lava flows. We present the first suitable data from the Arctic region,
comprising 37 paleomagnetic directions from Jan Mayen (71°N, 0.2–461 ka) and Spitsbergen (79°N, 1–9.2 Ma) and five paleointensity results....

Investigations of the behavior of the geomagnetic field on geological timescales rely on globally distributed data sets from dated lava flows. We present the first suitable data from the Arctic region, comprising 37 paleomagnetic directions from Jan Mayen (71°N, 0.2–461 ka) and Spitsbergen (79°N, 1–9.2 Ma) and five paleointensity results....
The issue of permanent nondipole contributions to the time-averaged field lies at the very heart of
paleomagnetism and the study of the ancient geomagnetic field. In this paper we focus on paleomagnetic
directional results from igneous rocks of the southwestern U.S.A. in the age range 0–5 Ma and investigate
both...
