Article
Terrestrial inputs-induced eutrophication in the P-depleted Northeastern (NE) Mediterranean shelf waters has led to changes in particulate organic matter (POM) composition and distributions in the water column and surface sediments. The present study aimed to understand the impacts of terrestrial nutrient and POM inputs on coastal eutrophication, b...

Türkiye deniz alanlarının çoğunluğu 200 metreden daha derin suları kapsaması itibari ile derin deniz özelliğindedir. Özellikle Karadeniz ve son yıllarda geçirdiği değişim ile Marmara Denizi derin suları oksijensiz, anerobik solunumun baskın olduğu daha çok mikrobiyal hayata ev sahipliği yapan ekstrem habitatlar sayılmalıdır. Akdeniz ise denizaltı k...

Son dönemde Marmara Denizi’nde yoğunlukla gözlemlenen; görsel, ekolojik ve ticari yönlerden sebep olduğu olumsuz etkileri nedeniyle kamuoyunun gündemine oturan deniz salyası sadece bugün değil geleceğimizi için de tehlike oluşturuyor. Bu bağlamda Türkiye Bilimler Akademisi Başkanlığı, konusunda uzman bilim insanları bu çevre sorununu değerlendirmel...
Presentation
Seafloor biogeochemistry and benthic fluxes can dramatically shift in response to deoxygenation and eutrophication-driven organic carbon production. In such conditions, biogeochemical cycling of key nutrients (N, P) can be highly coupled to oxygen concentrations and metal (Fe, Mn) redox cycles, often leading to the increase in dissolved P and Fe co...
Article
Full-text available
The Eastern Mediterranean and its Cilician Basin offshore waters have oligotrophic features with low nutrient concentrations, low primary production, and high water transparency. However, the wide shelf area of the Cilician Basin is subject to contaminated river inflows with enhanced nutrient loads and direct discharges of urban wastewaters of sout...
Conference Paper
In this study, biochemical (nutrients, total phosphorus (TP), biological oxygen demand) parameters were determined seasonally at downstream points of the five regional rivers (major/small ones: Ceyhan, Seyhan, Goksu, Berdan, Lamas) flowing into wide shelf zone of the northeastern (NE) Mediterranean. Long-term chemical data obtained seasonally in th...

Eutrophication-related physical and biochemical parameters were measured in shallow coastal waters of both bays located in northeastern Mediterranean during summer and winter for the period 2014-2018 to assess present trophic status of the coastal areas receiving substantial amount of nutrients and organic matter from the local perennial rivers and...
