Abstract
This paper concerns the nutrient status and the oxygen deficient conditions in the Elefsis Bay, an anoxic basin in the Saronikos Gulf. The concentration of nutrients and dissolved oxygen have been determined during seasonal surveys of water characteristics. The Elefsis Bay threatened by organic overload is in a more serious state of degradation than the rest of the Saronikos Gulf and the destratification phenomenon has substantial effects on the distribution and circulation of oxygen and nutrients in the bay. The oxygen utilization rates ranged between 1.3 and 1.8 ml‐1 month‐1 from March to June and were considerably higher than those reported for oceanic waters. The nutrient enrichment appears to be considerably influenced by eutrophication and human activity. Comparison of nutrient levels in Elefsis Bay and in other coastal waters of the Aegean Sea is carried out.
