Late quaternary paleomagnetic secular variation and chronostratigraphy from ODP sites 1233 and 1234

Creator:: Lund, Steven P., Stoner, Joseph, and Lamy, Frank
Abstract:: During Ocean Drilling Program Leg 202, detailed shipboard paleomagnetic measurements at Sites 1233 and 1234 identified a reproducible high-resolution record of paleomagnetic secular variation (PSV) at each site. These records also contained evidence for three magnetic field excursions. This paper summarizes the complete paleomagnetic record from Site 1233 and the...

DC trains and Pc3s : source effects in mid-lattitude geomagnetic transfer functions

Creator:: Egbert, Gary D., Eisel, Markus, Boyd, O. Sierra, and Morrison, H. Frank
Abstract:: Magnetotelluric (MT) data from two sites 150 and 300 km southeast of San Francisco, California (geomagnetic dipole latitude: 43 degrees, L approximately 1.9) show that the usual MT assumption of spatially uniform external magnetic fields is violated to a significant degree in the period range 10-30 s. Inter-station transfer functions...

Detailed paleomagnetic and rock magnetic variability within three high-resolution study intervals from site 1233

Creator:: Lund, Steven P., Stoner, Joseph, Channell, James, and Lamy, Frank
Abstract:: We carried out a detailed rock magnetic and paleomagnetic study of deep-sea sediments from selected intervals of Site 1233 in order to assess whether they contain reproducible evidence for submillennial-scale environmental, climatic, and geomagnetic field variability. Three 1.5-m sediment intervals from oxygen isotope Stages 1, 2, and 3 were sampled...

Paleomagnetism of the southwestern U.S.A. recorded by 0-5 Ma igneous rocks

Creator:: Tauxe, Lisa, Constable, Catherine, Johnson, Catherine L., Koppers, Anthony A. P., Miller, Winter R., and Staudigel, Hubert
Abstract:: 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...

Influence of the Amsterdam/St. Paul hot spot along the Southeast Indian Ridge between 77° and 88°E: Correlations of Sr, Nd, Pb, and He isotopic variations with ridge segmentation

Creator:: Nicolaysen, K. P., Frey, F. A., Mahoney, J. J., Johnson, K. T. M., and Graham, David W.
Abstract:: The submarine Amsterdam-St. Paul (ASP) Plateau, bisected by the Southeast Indian Ridge (SEIR), is a bathymetric high rising ~2 km above the surrounding seafloor that includes the islands of Amsterdam and St. Paul; this excess volcanism is attributed to a mantle hot spot. We obtained new Sr, Nd, and Pb...

A paleomagnetic approach toward refining Holocene radiocarbon-based chronologies: Paleooceanographic records from the north Iceland (MD99-2269) and east Greenland (MD99-2322) margins

Creator:: Stoner, Joseph, Jennings, Anne, Kristjánsdóttir, Gréta B., Dunhill, Gita, Andrews, John T., and Hardardóttir, Jorunn
Abstract:: We report the intercalibration of paleomagnetic secular variation (PSV) and expanded postglacial sediment cores from geographically proximal, but sedimentologically contrasting settings. The objective is to improve relative what can be achieved with either method alone. Core MD99-2269 was taken from north Iceland shelf. Core MD99-2322 was collected from the Kangerlussuaq...

Local time effects in satellite estimates of electromagnetic induction transfer function

Creator:: Balasis, Georgios, Egbert, Gary D., and Maus, Stefan
Abstract:: The current satellite magnetic missions offer new opportunities to determine the electrical conductivity of the Earth. However, satellites are nearly stationary in local time and therefore sample the inducing and induced fields quite differently than geomagnetic observatories, which rotate with the Earth. We show that estimates of induction transfer functions...

Empirical orthogonal function analysis of magnetic observatory data : further evidence for non-axisymmetric magnetospheric sources for satellite induction studies

Creator:: Balasis, Georgios and Egbert, Gary D.
Abstract:: Although satellite electromagnetic induction studies have usually assumed a symmetric magnetospheric ring current source, there is growing evidence for significant source asymmetry. Here we apply empirical orthogonal function methods to mid-latitude night-side hourly mean geomagnetic observatory data to search for evidence of nonzonal low-frequency source fields. The dominant spatial mode...

Temporal variability of Cd, Pb, and Pb, isotope deposition in central Greenland snow

Creator:: Sherrell, R. M., Boyle, E. A., Harris, N. R., and Falkner, Kelly
Abstract:: We present a decade-long (1981–1990) high-resolution (subseasonal) record of Pb and Cd concentrations and Pb isotopic composition in a series of 119 snow samples from a 6-m snow pit at Summit, Greenland. Both metals show order of magnitude seasonal variability, with maxima in spring of every year, coinciding with sulfate...
