Application of hyperspectral remote sensing for monitoring eutrophication indicators in the Adriatic Sea coastal zones and inland waters
This thesis focuses on the application of current and upcoming hyperspectral sensors with high spectral and spatial resolution for the monitoring of eutrophication indicators in coastal zones and inland waters, which due to their biological and optical complexity compared to the open seas presents a challenge for remote sensing. The laboratory measurements of water quality parameters were done in the river Sava and in the Kaštela bay. In parallel, the spectral data was recorded in water column and just above the water surface. The air-borne hyperspectral image was taken over the research area at the Sava river by using the AISA Eagle sensor. The hyperspectral image over the Kaštela bay was obtained from the Hyperion satellite sensor. High and statistically significant empirical correlations were found between the hyperspectral data and in-situ measured chlorophyll a (Chl-a), total suspended solids (TSS) and turbidity values.As an original scientific contribution, the empirical algorithms were developed for the extraction of observed eutrophication indictors in the Adriatic coastal zones and in the Sava river using hyperspectral data on the different spatial scales. The possibility to use remote sensing of invasive Caulerpa species as a supplementary indicator of eutrophication was also examined. As a scientific contribution to this effort, the hyperspectral profiles of C. taxifolia and C. racemosa var. cylindracea from the Adriatic Sea were for the first time recorded and analysed.
