Abstract: Στη συγκεκριμένη εργασία μελετήθηκαν οι φυσικοχημικές παράμετροι που επιδρούν στη ποιότητα των υδάτων της λιμνοθάλασσας, διαταράσσοντας την ισορροπία του οικοσυστήματος, προκειμένου να αποκαλυφθούν οι πιθανές περιβαλλοντικές επιπτώσεις που δημιουργούνται σε αυτό, από τις κλιματικές αλλαγές που επικρατούν στη περιοχή.
Abstract (translated): The Kotychi lagoon is located in the north-west of Peloponnese and constitutes a very significant ecologic heritage not only for the particular area but also for Greece in general. The great ecologic and economic value that characterises the lagoon and the wetland habitat around it has been acknowledged under international treaties (RAMSAR), European programs for the protection of the nature (NATURA 2000) and its bio-diversity while jointly there is an intense interest for its conservation and protection. In this particular research, the physiochemical parameters that affect the quality of the water of the lagoon were considered, by deranging the balance of the ecosystem having as a purpose to detect the presumable environmental reverberations that have been occurred due to climatic changes that affected the area. The temperature of the water of the lagoon follows a natural daily fluctuation. The lowest average temperatures of the water are recorded during the winter, whereas the highest average temperatures are recorded during the summer. The specific conductivity of the water shows significant fluctuation which is created by the entry-exit process of the marine and fresh water in the lagoon. The figures of the solution oxygen present a significant daily fluctuation that follows accordingly all the fluctuations of the temperature of the water, also fluctuate in normal rates and they do not alienate the pisci-fauna. The PH rate of the water presents a natural daily fluctuation of a 0.5 rate which is proportional to the temperature and the concentration of the solution oxygen. The water of the lagoon can be characterised as properly clear. The average levels of the chlorophyll for all the duration of the research period have been quite low, which is a case that shows that the lagoon does not show any important problems of eutrophy from photosynthetic organisms.
