Abstract

SAMMENDRAG Utstyr for kartlegging av sjøbunnens elektriske konduktivitet og som omfatter flere dataloggings-enheter, hvor da hver enhet (100) utgjør en sammenstilling tilpasset for utplassering på et visst sted på sjøbunnen med det formål å måle horisontale elektriske og magnetiske felter. Stivt festet og med vertikal utstrekning utover fra enhetssammenstillingen befinner det seg en vertikalorientert hovedsakelig stiv arm (158), men som har et par av vertikalt forskjøvede elektroder (160, 162) anordnet på armen for å frembringe en vertikalorientert dipolantenne. Elektrodene befinner seg i elektrisk kommunikasjon med en forsterker plassert inne i den sammenstilling som genererer et forsterket signal som så avgis til en dataloggingsprosessor som også er plassert inne i sammenstillingen. Denne prosessor velger da ut tidsserier av forsterkede elektriske felt samt magnetiske signaler over en forutbestemt tidsperiode.
