Environmental and Scientific Developments in Istanbul

 

Environmental and Scientific Developments in Istanbul

Recent environmental and scientific efforts in Istanbul highlight both marine conservation and agricultural research. In the Sea of Marmara, environmental teams successfully detected and removed a massive 15,000-square-meter "ghost net" off the coast of Heybeliada island. The removal of this abandoned fishing gear is crucial for local marine life, as such nets persistently trap and kill aquatic creatures.

In the academic sphere, researchers affiliated with the Institute of Graduate Studies in Sciences at Istanbul University have published a study in Nature. The research details the rapid monitoring of drought and salinity stress responses in wheat using potential Raman spectroscopy, contributing vital data to agricultural resilience studies.

İstanbul Barajlarında Su Seviyesi Yüzde 70'e Ulaştı

İstanbul Su ve Kanalizasyon İdaresi (İSKİ) verilerine göre, İstanbul'a içme suyu sağlayan barajların ortalama doluluk oranı son bahar yağışlarının ardından yüzde 70,05 seviyesine yükselmiştir. Bu artış, Türkiye'nin en büyük metropolünün su tedarik sistemindeki mevcut baskıyı kısa vadede hafifletmiş olsa da, uzmanlar kent altyapısı ve uzun vadeli su rezervlerinin sürdürülebilirliği konusunda yapısal önlemlerin önemini vurgulamaya devam etmektedir.

Heavy Rainfall and Pontoon Bridges Lead to Severe Pollution in Istanbul's Golden Horn

 

Heavy Rainfall and Pontoon Bridges Lead to Severe Pollution in Istanbul's Golden Horn

A combination of extreme urban runoff from severe storms and restricted water circulation has caused visible discoloration and turbidity in Istanbul's Golden Horn. Marine science experts indicate that heavy rainfall carried land-based pollutants and sediments into the estuary, overwhelming the city's capacity to filter the surface water.

Furthermore, structural barriers—specifically pontoon bridges—have limited the natural circulation of the water, trapping the polluted runoff in a stagnant environment. Experts warn that the reduced water clarity blocks sunlight from reaching deeper layers, placing significant stress on the fragile marine ecosystem. Upgraded continuous monitoring and evolving management approaches are being recommended to combat the ecological effects of increasingly frequent extreme weather events.

Severe Weather Besieges Istanbul: Transport Grounded and Accidents Spike, but Reservoirs Benefit

Heavy rainfall across Istanbul has led to severe disruptions in both transportation and daily life, while simultaneously providing a much-needed boost to the city's water reserves. Sabiha Gökçen Airport experienced significant operational difficulties, with reduced visibility forcing the grounding of air traffic and the cancellation of dozens of flights. In a tragic incident linked to the adverse weather conditions, a police service vehicle crashed on the Northern Marmara Highway, resulting in the death of one officer and injuries to 16 others. Despite these infrastructural and human tolls, the persistent downpours have had a positive environmental impact, raising the average water levels of reservoirs supplying Istanbul to 58.03%, marking a substantial recovery from previous lows.
