- Abstract
In various parts of the world, the decrease in dissolved oxygen (DO) in the lakes has affected negatively their quality. In Mexico, the Chapala Lake is the most important water body, since it has a transcendental role in the productive development of the region. Nevertheless, is also one of the most polluted bodies of water, therefore, the monitoring of the water quality is an important issue for its management. However, time and cost, involved in a constant sampling, are some of the main limitations for such monitoring. Therefore, we used alternative methodologies based on geostatistical approaches. In this way, we studied the OD spatialtemporal continuity of OD, through interpolations defined with ordinary kriging. The results showed that it was possible to model the variation spatial-temporal of OD concentrations, both along the Lake of Chapala, as at different depths. However, in some cases, the variograms presented a spatial trend at a global level. Therefore, in future work, we suggest to modeling OD based on universal kriging.
