Abstract

Eutrophication processes and changes in coastal ecosystem are determined by the coastal/open sea interactions and rates of nutrient pollution. The Cilician Basin shelf waters are affected not only by intense industrial activities and increased population, but also by complex atmosphere-sea-land interactions. There is a recognizable difference between water qualities of Mersin bay coastal and the Cilician open waters depleted in nutrients. Eutrophic conditions have developed in the eastern bay shallow waters heavily polluted by land-based inputs during the last few decades. In the present study, basic chemical parameters measured seasonally in water column during the 8 field surveys, as a part of TUBITAK project, in the period of November 2005-September 2007, have been evaluated. Cilician coastal waters were always poor in reactive phosphate (0.02-0.05 μM) throughout the year. However, there is a distinct decrease and seasonal changes in total phosphorus (TP) levels from the polluted inner bay (0.15-0.20 μM) to the Cilician open waters (0.05-0.07 μM). The surface TRIX index values, computed from % dissolved oxygen saturation, dissolved inorganic nitrogen, TP and chlorophyll-a concentrations, increase from 4 (showing tendency from mesotrophic to eutrophic propery), biomass level is high and the Secchi Disc depth varies between 1.5-3 meters. İskenderun inner bay waters have low levels of organic pollution and TRIX

Özet

Kuzeydoğu Akdeniz'in Kilikya Baseni kıta sahanlığı suları, yoğun nüfus artışı ve endüstriyel atıksular ve nehir kaynaklı kirleticilerin neden olduğu olumsuz ekolojik değişimlerin yanısıra, atmosferik (yağmur ve toz) girdilerden birinci derecede etkilenir. Açık denizle etkileşiminin zayıf ve karasal (nehirler, atıksu) kirleticilerin yoğun baskısı altında olan Mersin Körfezi doğu bölgesinin sığ kıyısal bölgenin su kalitesini son çeyrek yüzyılda kötüleştirmiş ve ötrofik koşullar gelişmiştir. Bu çalışmada, Kasım 2005 - Eylül 2007 döneminde, TÜBİTAK projesi kapsamında Kilikya baseninde toplam 8 saha çalışmasında ölçülen temel kimyasal parametrelerin zaman ve mekan içinde değişimleri değerlendirilmiştir. Kıyısal bölgenin yüzeyden tabana kadar uzanan su kolonu reaktif fosfat (PO4 3-) iyonlarınca her zaman fakirdir (0,02-0,05 μM). Ancak, toplam fosfor (TP) derişimi kıyıda yüksektir (0,15-0,2 μM); açık sularda 0,05-0,07 μM seviyesine düşer. Yüzey sularında ötrofikasyon göstergesi olarak kullanılan TRIX indeksi parametresi (çözünmüş oksijen (%O2), çözünmüş inorganik azot, TP ve klorofil-a ölçümlerinden hesaplanır) Mersin Körfezinin açık sularında düşüktür (4 (mezotrofik özellikten ötrofik duruma yöneliş) olup, fitoplankton kaynaklı biyokütle yüksektir ve seki disk derinliği yıl boyunca 1,5-3 metre aralığındadır. İskenderun iç körfez yüzey sularında TRIX
