At the end of June 2021. we successfully completed the first assembly of the new Teledyne RESON hydrographic depth gauge, model SeaBat T50-P, using our hydrographic vessel as a working platform. The device was purchased by the Faculty of Geodesy Zagreb through a public tender and the company GEOmar provided the service of sale, installation and commissioning, with online support from Teledyne experts and the participation of experts from the Faculty of Geodesy, Department of Hydrography. This hydrographic system represents the last word in hydrographic technology with superior characteristics of precision, reliability and high resolution of collected bathymetric survey data.
