| Popis: | Intention of this work was to examine all available recent geomagnetic survey data, in order to assess Palagruža as a potential location for a permanent variometer station. The most recent data consist of absolute, total intensity vertical gradients and Overhauser effect dIdD vector measurements, carried out in period 2008– 2010. Evidences were found in low crustal field estimates, relatively low total field vertical gradient distribution over the island, quite high time series correlation with the near observatories, as well as in low noise level of geomagnetic components. These preliminary results indicate Palagruža as appropriate location for the repeat station as well as for the variometer station. However, additional investigations of the geomagnetic sea and coastal effects by using much longer time series are needed. |
