Abstract:
The modern use of the A-10 gravimeter in Romania and its future application for characterizing mud volcanoes are proposed in this study. Gravimetry, a fundamental tool in geophysical research, offers unique insights into subsurface geological structures. There is no available data due to national regulation constraints, all the published gravity maps being post-processed from the same initial classified data sets. This is why the utilization of the A-10 gravimeter represents a turning point in Romanian geophysics, providing researchers with precise gravity measurements for the first time. We began our approach by familiarizing ourselves with the equipment and its capabilities. This involved gathering data from gravity control points of class A0 in Timișoara, Constanța, Bucharest, and other A1-class points across Romania. On a national level, it is a rare and unique opportunity to compare two A-10 Gravimeters, the second one having been recently acquired by the National Center for Cartography. To take full advantage of this situation, we plan field methods, tests, and measurement campaigns at the aforementioned class points. Building upon this foundation, our research aims to collect and interpret micro-gravimetric data to enhance our understanding of Berca Mud Volcanoes in Romania. Much of the existing literature aims at characterizing the deep reservoir from which expelled fluids are anticipated to originate. Another segment of research focuses on the study of the shallow system of mud volcanoes, which potentially impacts short-term fluctuations in their activity. Our objective is to gather and analyze a novel dataset of micro-gravimetric data to understand the Berca Mud Volcanoes in Romania, aiming to address both the deep reservoir and shallow system aspects. Once we gather the data around the volcano, we'll conduct thorough research and employ advanced data analysis techniques to reach meaningful conclusions. We anticipate that the application of micro-gravimetric data will provide invaluable contributions to our approach into mud volcano characterization, facilitating informed decision-making in hazard assessment and resource management.
