Abstract:
Version 3 of GEOMAGIA50 is the product of an international collaboration to develop a comprehensive online database that allows easy access to published paleomagnetic and chronological data from the past 50 ka. The overarching scientific goal is to improve our understanding of changes in the geomagnetic field, with applications ranging from the deep Earth, to past environments and climate, to the interaction of the geomagnetic field with the space environment. We present the large range of modifications made to the database since its initial release in 2006. The most significant is the addition of paleomagnetic, rock magnetic and chronological data obtained from lake and marine sediments. An emphasis has been placed on geochronological data from sediments and the database includes comprehensive radiocarbon age data, oxygen isotope data, varve ages and tephra ages. In the archeomagnetic and volcanic database, the amount of declination, inclination and paleointensity data has been increased greatly and now exceeds 15,000. In addition, a number of new metadata fields have been added, e.g., more specific information about the archaeological or volcanic sites the data were obtained from. Finally, the web interface has been updated. This includes a new query form for the sediment database and improved functionality of the archeomagnetic and volcanic query form.
