title: Comparative Assessment of the Trophic Level of the Sevastopol and Yuzhnaya Bays Using E-TRIX Index
abstract: The ecological state of the Sevastopol Bay and the Yuzhnaya Bay is compared by their trophic level using the E-TRIX index. E-TRIX is defined by four state variables, which are strongly correlated with primary production: chlorophyll a, oxygen as absolute % deviation from saturation, dissolved inorganic nitrogen, and total phosphorous. The annual dynamics of biogenic elements is calculated; the one-dimensional water quality model, which has been calibrated for the referred water areas, is used. T
