Abstract

Coastal lagoons are transitional zones between riverine and marine systems where nutrients and contaminants often accumulate in these aquatic environments. In the present study, physical and biochemical data were obtained from the five stations between January and December 2022 for the determination of trophic status in the Akyatan Lagoon. The study results indicated the values of physical and eutrophication-related parameters displayed spatial and temporal variability. The trophic status of Akyatan Lagoon was determined by using two multi-metric classification tools as Trophic index (TRIX) and the Trophic status index (TSI). The calculated TRIX values ranged from 4.88 to 7.90 whilst the TSI values varied between 50.0 and 77.4. The strong and positive correlations between the TRIX and TSI values with their high values strongly suggested hypereutrophic conditions in the ecologically and economically important Akyatan Lagoon caused by contaminated Seyhan River inflows due to terrestrial nutrients and organic matter inputs.

沿海泻湖是河流和海洋系统之间的过渡地带，营养物质和污染物经常在这些水生环境中积累。本研究获取了 2022 年 1 月至 12 月期间五个站点的物理和生物化学数据，以确定阿亚坦泻湖的营养状态。研究结果表明，物理和富营养化相关参数的值具有时空变异性。阿亚坦泻湖的营养状况是通过营养指数（TRIX）和营养状态指数（TSI）这两种多指标分类工具确定的。计算得出的 TRIX 值介于 4.88 到 7.90 之间，而 TSI 值介于 50.0 到 77.4 之间。TRIX 值和 TSI 值之间的强正相关性及其高值有力地表明，由于陆地营养物质和有机物质的输入，塞罕河流入的污染造成了生态和经济上重要的阿亚坦泻湖的高富营养化状况。

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
