Abstract (2. Language): 
Magnetotelluric data collected at the western part of the North Anatolian Fault Zone and the two-dimensional analysis associated with them, are likely to be influenced by the “ocean effect”. Two and three dimensional forward modeling tests were performed at a geometry that is representing the western edge of the Armutlu Peninsula. The results following these tests suggested that the two dimensional inversions should depend on B-polarization rather than E-polarization for Armutlu Peninsula geometry.

Abstract (Original Language): 
Kuzey Anadolu Fayı’nın batı kesiminde gerçekleştirilen manyetotelürik ölçümlerde toplanılan verinin ve veriye ait ikiboyutlu (2B) analizlerin, yüksek elektrik iletkenliğe sahip Marmara Denizi’nden kaynaklanan deniz etkisine maruz kalacakları gözönünde bulundurularak, etkinin boyutunu tespit etmek üzere, iki-boyutlu (2B) ve üç-boyutlu (3B) düz çözüm denemeleri yapılmıştır. Buna göre Armutlu Yarımadası’nın batı kesiminde iletkenliği etkileyebilecek unsurlar sentetik yer modelleri oluşturularak sınanmışlardır. Sonuç olarak, test edilen geometride, 2B ters çözüm analizlerinin doğruluğunu arttırmak için, deniz etkisini baskın biçimde taşıdığı saptanan, E-polarizasyonu verisi yerine ağırlıklı olarak B-polarizasyonu verisinin kullanılması gerekmektedir.
