A new national geomagnetic network of repeat stations for total field F, horizontal component H, vertical component Z and declination D has been established in a collaboration between the Albanian Geological Society (Center for Geochemistry and Geophysics), the Tirana University (Albania) and the Istituto Nazionale di Geofisica (Italy). From the observed magnetic field elements all repeat stations were referred to Epoch 1994.75 and normal reference fields were computed in the form of 1st order polynomials in latitude and longitude. An overview of all work, including a brief history of the Albanian magnetic measurements, magnetic survey results, normal fields and secular variation estimates is presented.
A survey of 116 repeat stations of the Italian Magnetic Network was carried out between 1989 and 1992. We describe the characteristics of the selected network repeat station sites, the characteristics of the measuring equipment, the data reduction procedure and the analysis in terms of normal field, data mapping and secular variation. Together with the values from our previous campaigns, we also determined, for all elements, the normal fields of secular variation. The new repeat station data are listed. Results, maps and normal fields are discussed with respect to previous work and future survey plans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
