Paleomagnetic Data from NGDC / WDC Boulder
The study of magnetism is one of the oldest of the geophysical sciences. It is unique among the sciences in that ancient records of the geomagnetic field are preserved in rocks and changes in the field can be traced through time. To assist scientist studying the Earth's ancient magnetization, the National Geophysical Data Center (NGDC) is making available the following data of paleopole positions and paleomagnetic directions.
IAGA Paleomagnetic Databases
NGDC is pleased to archive and distribute via ftp the IAGA sponsored Paleomagnetic Databases initiated by McElhinny et. al. The seven IAGA databases are described below. The Geological Survey of Norway provides web access to the Global Paleomagnetic Database (see Web Access below).
There are seven databases as follows:
The Archeomagnetic directional database, Paleointensity database, and Secular Variation from Lake Sediments database (numbers 2, 4 and 6 above) have no new information included from the previous versions (3.4 May 1999). All other databases are complete up to December 1999 and in some cases include data from early in 2000.
McElhinny and Lock (1996) give a description of the Access versions of the GPMDB, TRANS and SECVR. Details of PSVRL are given in McElhinny and McFadden (1997). Perrin, Schnepp and Shcherbakov (1998) give a brief description of PINT and McElhinny, Opdyke and Pisarevsky (1998) give a description of MAGST. ARCHEO is a new archeomagnetic directional database compiled by Don Tarling at the University of Southampton, U.K. It is not yet complete but was released in 1999.
