Croatian Geomagnetic Networks

Geomagnetic networks in Croatia consist of the repeat stations network, and the part of network for field mapping nowadays. The Croatian Geomagnetic Repeat Stations Network was established in 2004. Herewith, the setup of two additional repeat stations in 2008 is described. Lessons learned during the repeat station surveys of 2004, 2007, and 2008 are revealed. The design of the dense Croatian Geomagnetic Network for Field Mapping, that is to consist of approximately 90 stations with the average distance from one station to another of 25 km, is presented. The setup and the survey of the first third of the network, covering the southern Dalmatia, including islands, was completed in summer 2008. The instruments and procedures used, as well as the experiences gained are described. In addition, the attempts to determine the total intensity of geomagnetic field on the Adriatic volcanic islands of Jabuka and Brusnik are presented.
