In this work we present novel results concerning water quality changes in an eutrophic water body connected with an artificial aeration system installed in it. Sixty one in-situ and laboratory measurements of biogeochemical variables were recorded monthly between October 2008 and June 2011 to evaluate temporal and spatial changes in San Roque reservoir (Argentina). t-Student mean difference tests, carried out over the whole period, showed with 95% confidence that a monitoring point located at the centre of the water body is representative of the chemical behaviour of the reservoir. Thermal stratification was observed in all sampling sites in the summer, but the frequency of these episodes was markedly lower in bubbling zones. Mean chlorophyll-a concentrations were 58.9 μg∙dm–3 and 117.0 μg∙dm–3 in the absence and in the presence of thermocline respectively. According to the t-Student test, this difference was significant, with p < 0.001. Phosphate release from sediments was corroborated under hypoxia conditions. ANOVA one way analysis did not show significant spatial differences for any variable. Mean normalize spatial index (MENSI) was developed to compare data from different regions affected by high temporal variability. It proved to be useful to quantify spatial differences. Structure analysis of temporal series was used to scrutinize both chemical and spatial association successfully. Three chemically different zones were determined in the reservoir. This study demonstrated that spatial comparisons by means of marginal statistics may not be an adequate method when high temporal variation is present. In such a case, temporal structure analysis has to be considered.

W pracy przedstawiono oryginalne wyniki dotyczące zmian jakości wody w eutroficznym zbiorniku wodnym związanych z zainstalowanym tam systemem sztucznego napowietrzania. Od października 2008 do czerwca 2011 r. dokonywano co miesiąc in situ i w laboratorium 61 pomiarów parametrów biogeochemicznych aby ocenić czasowe i przestrzenne zmiany w zbiorniku San Roque (Argentyna). Testy t-Studenta prowadzone dla całego okresu badawczego wykazały z 95-procentowym poziomem ufności, że stanowisko monitoringu zlokalizowane w centrum zbiornika wodnego jest reprezentatywne dla właściwości chemicznych całego zbiornika. Stratyfikację termiczną obserwowano latem we wszystkich stanowiskach badawczych, ale częstość wystąpień tych epizodów była znacząco mniejsza w strefie napowietrzania. Średnie stężenie chlorofilu a wynosiło 58,9 μg∙dm–3 i 117,0 μg∙dm–3 odpowiednio w warunkach braku i w warunkach występowaniu termokliny. Różnica wg testu t-Studenta była statystycznie istotna, gdy p < 0,001. Stwierdzono uwalnianie fosforanów z osadów w warunkach deficytu tlenowego. Jednoczynnikowa analiza ANOVA nie wykazała istotnego zróżnicowania przestrzennego żadnego z mierzonych parametrów. Utworzono średni znormalizowany indeks przestrzenny (MENSI) do porównania danych cechujących się dużą zmiennością czasową pochodzących z różnych regionów. Indeks okazał się użyteczny do ilościowego przedstawienia różnic przestrzennych. Przeprowadzono analizę struktury szeregów czasowych, aby przeanalizować powiązanie cech chemicznych ze zmiennością przestrzenną. Wyodrębniono trzy chemicznie odmienne strefy zbiornika. Badania wykazały, że analiza przestrzenna za pomocą statystyki jednoczynnikowej może nie być odpowiednią metodą w warunkach dużej zmienności czasowej. W takim przypadku należy rozważyć analizę struktury czasowej.
