Artificial Neural Networks (ANNs) have wide applications in aquatic ecology and specifically modelling water quality biotic responses to environmental predictors. However, data scarcity is a common problem that raises the need optimize approaches overcome limitations. With this paper, we investigate optimal k-fold cross validation building an ANN using small water-quality set. The was created model chlorophyll-a levels of shallow eutrophic lake (Mikri Prespa) located N. Greece. typical...
During the last decades, Mediterranean freshwater ecosystems, especially lakes, have been under severe pressure due to increasing eutrophication and water quality deterioration. In this article, we compared effectiveness of different data analysis methods by assessing contribution environmental parameters processes. For purpose, principal components (PCA), cluster analysis, a self-organizing map (SOM) were applied, using from two transboundary lakes North Greece. SOM is considered as an...
Abstract The southern Red Sea is a key region for investigating the effect of climate forces on semi-closed basin. Detailed micropaleontological (planktic foraminifera) and isotopic (δ 18 Ο, δ 13 C) analyses along with reconstructions sea surface temperature salinity sediment core from Farasan banks revealed imprints level changes South Asian Monsoon area. Comparison surrounding records provided insights Sea-Gulf Aden (GoA)-Northwestern Arabian (NWArS) water exchange pattern over last 30 ka....
Lake Pamvotis (Greece) is a shallow hypereutrophic lake with natural tendency to eutrophication. Several restoration measures were applied, but no long-term success. To examine the causes for this an Artificial Neural Network (ANN) was created in order simulate chlorophyll-a (Chl-a) levels and investigate role of associated environmental parameters. The ANN managed good correlation simulated Chl-a can be considered as reliable predictor. relative importance parameters calculated use "Partial...
Eutrophication is a major environmental issue with many negative consequences, such as hypoxia and harmful cyanotoxins production. Monitoring coastal eutrophication crucial, especially for island countries like the Republic of Cyprus, which are economically dependent on touristic sector. Additionally, open-sea aquaculture industry in Cyprus has been exhibiting an increase last decades monitoring to identify possible signs mandatory according legislation. Therefore, this modelling study, two...
Abstract Coastal hypoxia is a serious environmental problem that needs to be addressed at global level. The phenomenon of characterized by low Dissolved Oxygen (DO) levels in the water column causes detrimental effects on aquatic organisms. Anthropogenic activities such as intensive agriculture practices and point-source nutrient loading are considered main coastal hypoxia. This study utilizes data-driven modelling based Artificial Neural Networks (ANNs), specifically Feed-Forward ANNs,...
A surfeit of Dissolved Inorganic Nitrogen (DIN), which is defined as the total amount nitrite, nitrate, and ammonium levels in water, may cause negative effects to marine environment. For example, elevated DIN promote surplus production algae possible depletion oxygen water column. The column monitored part Water Framework Directive (WFD), Nitrates EU Marine Strategy (MSFD). Data-driven models have been proved be an excellent management tool for environmental issues related coastal quality...
Eutrophication is a major environmental issue with many negative consequences, such as hypoxia and harmful cyanotoxin production. Monitoring coastal eutrophication crucial, especially for island countries like the Republic of Cyprus, which are economically dependent on tourist sector. Additionally, open-sea aquaculture industry in Cyprus has been exhibiting an increase recent decades monitoring to identify possible signs mandatory according legislation. Therefore, this modeling study, two...
Good coastal water quality is important for human well-being but also marine organisms. The European Water Framework Directive (2000/60/EC) has established threshold values regional seas, with Cyprus collaborating Greece to assess conditions and set common chlorophyll-a (chl-a) thresholds. In the Levantine Basin, known its oligotrophic waters, chl-a levels categorize quality: under 0.1 (μg/l) indicates high quality, 0.4 good over moderate quality. A study developed a Probabilistic Neural...
