Simona GHIȚĂ; Irina STANCIU; Adrian SABĂU; Iuliana-Mihaela ȘUNDRI10/1/202410.53464/JMTE.02.2024.05Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesIn the present study, the physico-chemical quality of the water in the Midia coastal area, the Tasaul Lake and the Siutghiol Lake water bodies were analyzed, as integrated sites in the territory of the North Dobrogea FLAG. This study allows establishing the state of favourability of the aquatic ecosystem, focusing on the chlorophyll content as the basis of the trophic level. The premise of a stable ecosystem induces the possibility of developing natural fish resources. An essential attribute in the context of preserving natural heritage and increasing the attractiveness for fishing activities, is the need to evaluate the qualitative and quantitative profile of the phytoplankton and, respectively, the eutrophication indicators. If aquaculture activities will be developed in the analyzed areas in the future, they could increase the economic value of the Romanian sector of the Black Sea. The biological analyzes of the water quality are the basis of the substantiation of some methods of its determination and evaluation. Thus, testing the concentration of chlorophyll, the classes of algae and the photosynthetic activity, are useful for the evaluation of eutrophication in the aquatic environment, but also for the evaluation of productivity in the surface waters studied. At the same time, the determination and evaluation of the physical and chemical parameters of water quality allowed the realization of some correlations with the structure of the biota. In this sense, the analysis methods are based on the use of modern equipment based on real time (in situ) determinations.Read More -

From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. The each other interconnected processes of mass and energy transfer are well visible in an integrated dynamic system called the hydrosphere. The hydrosphere is the combined mass of water found on, under, and above the surface of the Earth. Meteorological conditions undoubtedly have, in addition to different agro-ecological conditions, a significant influence on the monitored yields and crop quality. The paper presents the results of the soil monitoring at cherry orchard Žabčice, Czech Republic in place with different species of grassland with different lengths of their roots. Monitoring was realized manually with frequency one per month with using Z-meter devices developed through international EUREKA programme. The monitoring system allows measurement at one selected frequency of the measuring signal, or measurement in a frequency band. Both approaches were used to monitor changes in soil water content. Changes in the water content in the soil were monitored during artificial irrigation of grass (frequency spectrum) with a mobile probe and due to changes in the weather - drought and after torrential rain on the site (chosen frequency of the measuring signal) with stable probes. For practical reasons to limit the influence of uncertainties, the measurement was conceived as relative, and therefore calibration was not carried out for e.g. relative humidity of the soil. The monitoring results show the possibility of using the measuring system for the given purpose in full, including the possibility of its automation.Read More -
