Abstract :Direct discharges of domestic and industrial wastewaters to the coastal zone of Aegean Sea are an important concern. Design of an environmental baseline assessment program prior to any coastal development is a crucial part of the feasibility studies due to the complexity of the coastal dynamics.  The background biogeochemical status of the Nemrut Bay’s water column was set to assess the impact of a proposed industrial discharge. The seawater samples were collected on seasonal bases representing winter (mixed water column) and summer (stratified) conditions, and were analyzed for dissolved heavy metals (Hg, Cd, Pb, Cr, Cu, Zn, Mn, Ni, Fe, Mg), dissolved and particulate nutrients (NO 3 - , NO 2 - , PO 4 3- , Si, TOC, TPP, POC, PON), dissolved oxygen (DO) and chlorophyll-a (Chl-a) contents. The baseline assessment was based on the Turkish regulatory liabilities. The analyses of the samples showed that anthropogenic influence is mostly detected in stations closer to the shoreline. The Nemrut Bay has quite a low level of pollution regarding the impacts of high intensity of industrial and maritime activities in its vicinity are considered.
