The GEOMAGIA50 database - Index
The GEOMAGIA50 database is now up and running.
The GEOMAGIA50 is a database that comes with a web interface
intended to give users easy access to archeomagnetic
data. At present, the database contains about 8 000 determinations of geomagnetic
field directions and intensities for the past 50 000 years.
