PN16450203 – The movement of the Earth’s crust and the associated paleogeographic evolutions produced during the Holocene in the Danube Delta and the coastal area – Tools for the scientific substantiation of the integrated management of the coastal area and the Danube Delta Biosphere Reserve
Acronim: DELMAR
The project aimed to interdisciplinary approach the study of the time interval corresponding to the Holocene, that is, of about the last 11,700 years, starting from the assumption that only by deciphering the past and studying the situation of the present is possible the prediction of future evolution. The main targets pursued within the project are: determining the current geodynamic regime of the coastal area and deltaic area, as well as the current variation of the average sea level; studying the structure and content of the Holocene sedimentary quvert, in order to highlight and decipher the paleogeographic changes produced in the recent past.
- Introducing new instruments into the current research practice of the sedimentary structure of the Danube Delta, and other sedimentary basins as well. Ordering and commissioning of a percussion core system capable of taking continuous drills up to 15 m depth, of an electromagnetic metal detector with the complete set of antennas, capable of being used in geophysical prospecting both on land and in the underwater environment, up to 60 m depth, trailed by a ship or handled by a diver.
- Training young staff in an intensive course called “Theoretical and practical training on GNSS systems and processing of satellite observations”, which allowed the initiation of the process of advanced processing and exploitation of positioning data provided by the permanent GNSS stations of the GeoPontica geodynamic network, with immediate consequences on the study of deformations suffered by the earth’s crust in the Delta and coastal area. With the completion of the training on GNSS systems and the processing of satellite observations, the processing of data recorded in the GeoPontica network has become a permanent activity of GeoEcoMar researchers. Since the summer of 2017, this activity has been expanded, with permanent GNSS stations of the ROMPOS network under the administration of ANCPI also being included in the calculation procedure. On the occasion of the commissioning of the percussion core drilling system, several GeoEcoMar specialists took a practical training course in its use, and others were subsequently trained during field campaigns.
- Complex investigation of sites of interest located in the Danube Delta area. During the research project, three expeditions were organized to collect geological samples and conduct geophysical research in carefully selected areas, all located on the surface of the Danube Delta. Two of these expeditions involved the use of the fluvial and maritime-coastal research vessel “Istros”, the areas investigated in detail being located at Halmyris (Murighiol), Taraschina (Mila 23), Caraorman, Litcov and Răducu. A third expedition was carried out on land, the investigated sites being located at Halmyris (Murighiol) and Ad Stoma (Lower Danube);
- Consolidation and expansion of the institutional collaboration with specialists from the Institute of Eco-Museum Research (ICEM) in Tulcea, which allowed for the completion of complex studies of the Taraschina (Mila 23), Halmyris (Murighiol) and Ad Stoma (Dunavățul de Jos) sites, as well as the Collaboration and data exchange Protocol agreed with the National Agency for Cadastre and Real Estate Advertising, which allowed the inclusion in the processing of GNSS data and information provided by stations of the ROMPOS network.
