| 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. Cilj ovog rada je bio istražiti sve dostupne suvremene podatke geomagnetskih istraživanja, kako bi se Palagruža procijenila kao potencijalna lokacija za stalnu variometarsku postaju. Najnoviji podaci sadržavaju apsolutna mjerenja, mjerenja vertikalnih gradijenata ukupnog polja i vektorska mjerenja Overhauser-efekt dIdD instrumentom, koja su provedena u razdoblju 2008.–2010. Dokazi su pronađeni u procjenjenim malim poljima kore, raspodjeli relativno niskih vertikalnih gradijenata ukupnog polja preko otoka, prilično visokoj korelaciji vremenskih nizova sa bliskim opservatorijima, kao i u niskim razinama šuma geomagnetskih komponenata. Ovi početni rezultati nagovještavaju Palagružu kao primjerenu lokaciju za sekularnu postaju, kao i za variometarsku postaju. Međutim, potrebna su dodatna istraživanja geomagnetskih efekata mora i obale, koristeći dulje vremenske nizove. |
