In this work, the oceanographic aspects of the Golden Horn and some results of the Golden Horn Rehabilitation Project are presented. The hydrographic structure of the Golden Horn responds rapidly to the conditions in the southern Bosphorus, which is especially true for the outer parts of the estuary up to the Valide Sultan Bridge (VS). West of this bridge which was blocked by the pontoons of the bridge, carries the major pollution load and is dependent on the underlying water and surface mixing, for its renewal. The dissolved oxygen concentrations were measured below the detection limit in the region between the VS and Eyüp-Sütlüce (ES) section during the majority of the measurement periods where H2S has been determined simultaneously until February 2000. Although the microbial contamination of the estuary stations is very high, decreases in the contamination at stations are observed. The highest concentrations are recorded at the ES-VS section and supported by Fecal Coliform data during the rainy months in general despite the operational collector system surrounding the estuary. An obvious decrease of pollution in comparison with the data of the previous years is clearly observed as an encouraging result of the rehabilitation efforts achieved so far.
本文介绍了金角湾的海洋学特征以及金角湾修复项目的一些成果。金角湾的水文结构对博斯普鲁斯海峡南部的状况反应迅速，对于河口直至苏丹皇太后桥（VS）的外部区域尤其如此。这座桥的浮桥阻断了其西侧区域，该区域承载着主要污染负荷，其水体更新依赖于底层水和表层混合。在2000年2月之前的大部分测量期间，在VS和埃于普-叙特吕切（ES）断面之间的区域，溶解氧浓度低于检测限，同时还测定了硫化氢。尽管河口站点的微生物污染程度很高，但各站点的污染情况有所下降。总体而言，尽管河口周围设有收集系统，但在雨季，ES-VS断面记录到最高浓度，且有粪大肠菌群数据支持。与前几年的数据相比，污染明显减少，这是迄今为止修复工作取得的令人鼓舞的成果。
