Evaluation of sediment contamination by monoaromatic hydrocarbonsin the coastal lagoons of Gulf of Saros, NE Aegean Sea
The concentrations and distribution of monoaromatic hydrocarbons (benzene, toluene, ethylbenzene, and the sum of m-, p- and o-, xylenes) were determined in the sediments of coastal lagoons of the Gulf of Saros, using a static headspace GC–MS. The total concentrations of BTEX compounds ranged from 368.5 to below detection limit 0.6 μg kg−1 DW, with a mean value of 61.5 μg kg−1 DW. The light aromatic fraction of m-, p-xylene was the most abundant compound (57.1% in average), and followed by toluene (38.1%) N ethylbenzene (4.1%) N o-xylene (2.5%) N benzene (1.1%). The factor analysis indicated that the levels and distribution of BTEX compounds depend on the type of contaminant source (mobile/point), the absorbance of compounds in sediment, and mobility of benzene compound and degradation processes. Point sources are mainly related to agricultural facilities and port activities while the dispersion of compounds is related to their solubility, volatility, and effect of sea/saline waters on lagoons.The Research Fund of Istanbul University (Project BAP-179, Project 1479
OIL SPILL ALONG THE TURKISH STRAITS SEA AREA; ACCIDENTS, ENVIRONMENTAL POLLUTION, SOCIO-ECONOMIC IMPACTS AND PROTECTION
The Turkish Straits Sea Area (TSSA) is a long water passage that is consisted of the Sea of Marmara, an inland sea within Turkey's borders, and two narrow straits connected to neighboring seas. With a strategic location between the Balkans and Anatolia, the Black Sea and the Mediterranean, and dominated by the continental climate, the region hosted many civilizations throughout the centuries. This makes the region among the busiest routes in the world, with sea traffic three times higher than that in the Suez Canal. The
straits are the most difficult waterways to navigate and witnessed many hazardous and
important collisions and accidents throughout history. In addition, this area has vital roles as a biological corridor and barrier among three distinctive marine realms. Therefore, the region is rather sensitive to damages of national and international maritime activities, which may cause severe environmental problems.
This book addresses several key questions on a chapter basis, including historical accidents, background information on main dynamic restrictions, oil pollution, oil spill detection, and clean-up recoveries, its impacts on biological communities, socioeconomic aspects, and subjects with international agreements. This book will help readers, public, local and governmental authorities gain a deeper understanding of the status of the oil spill, mostly due to shipping accidents, and their related impacts along the TSSA, which needs precautionary measures to be protected.CONTENTS

Polycyclic Aromatic Hydrocarbons (PAHs) in the Surficial Sediments from Lake Iznik (Turkey): Spatial Distributions and Sources
The concentrations of 12 polycyclic aromatic hydrocarbons (PAHs) were determined from 28 sediment samples taken from the Lake Iznik located in the north-west area in Turkey. The total concentration of the PAHs was observed as in the range of 17–835 ng g−1 dry weight, with the highest values, recorded offshore the cities of Iznik and Orhangazi, and the Sölöz creek. According to the molecular indices, contamination of the PAHs in the lake was a mixture of the atmospheric input of high-temperature pyrolytic processes and the petrogenic sources transported by the creeks. Further, the higher proportion of high molecular-weight PAHs (>85%) suggests the domination of combustion-related sources. Compared to the consensus-based sediment quality guidelines for PAHs, there are no harmful biological effects on the short term to aquatic life.The Research Fund of Istanbul University; Grants YFK-423 and UDP-655
Heavy metal pollution in surface sediment and mussel samples in the Gulf of Gemlik
Sediment quality data provide essential information for evaluating ambient environmental quality
conditions. An evaluation is presented of heavy metal pollution, on the basis of statistical analysis of metal
concentrations from the sediments of the Gulf of Gemlik, southeastern Marmara Sea, Turkey, which has
been subject to high levels of pollution. The ranges for heavy metal concentrations (Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) at the 63 μm fractions. Not only large industrialized seaports but also resort areas throughout the Gulf are flagged as hotspots for elevated concentrations, generally higher compared to those from the other Turkish marine environment. The highest concentrations of Cr, Pb, and Ni were measured in the outer part of the Gulf, while the highest concentrations of Cu were documented offshore the main rivers. While the concentrations of Cr, Fe, Mn and Ni in some stations approach the severe effect level given in various sediment quality guidelines, the concentrations of the most human-related metals (Cd and Zn) in the mussels collected from the Port Mudanya were higher than the acceptable values for human consumption set by various health organizations.The research fund of the Istanbul University; project UDP-200
Seismic stratigraphy of the north-western Sea of Marmara shelf along the North Anatolian Fault system
The Ganos Fault, a part of the Northern strand of the North Anatolian Fault system, is an active- strike slip fault and divides the narrow NW shelf of the Sea of Marmara into two parts near the town of Gaziköy. This paper presents recently collected shallow high-resolution seismic data to discriminate the sedimentary successions, each characterized by distinctive stratigraphic patterns on both sides of the Ganos Fault. Two main units, namely U1 and U2, and three para-sequences (U1a, U1b and U1c) were identified, depending on their internal reflection patterns, accommodation depths as well as the presence of conformity and the unconformity surfaces. The thickness of Unit U1 reaches its maximum at the northern side of the Ganos Fault; it is much thinner to the south. The para-sequences of U1b and U1c have “progradation” and “aggradation to progradation” depositional characters, respectively. This probably implies fluvial deposition controlled by sea- level fluctuations. Unit U1b can only be observed at the northern side of the Ganos Fault, while Unit U1c at the southern side. Units U1a and U1b were deposited during the transgressive system tract, while Unit U1c was deposited during a sea-level fall and/or a lowstand phase marked by an erosional surface. The marine terraces in the study area are shallower than those along the northern shelf of the Sea of Marmara, possibly due to successive tectonic displacements along the Ganos Fault, which also controls the distribution and thickness of the parasequences identified in this study
Vulnerability of Turkish coasts to accelerated sea-level rise
Accelerated rise in sea-level, and associated geological adjustment, may result in a high impact on shorelines. On the basis of hourly sea-level observations over a 20 year period, sea-level change along the Turkish coast has been investigated. In addition to relative sea-level rise, the high level of human activities in coastal areas puts a significant amount of stress on Turkish coastal zones, especially on coastal lowland plains. Coastal erosion and ground water salinization are the most important impacts and two case studies are discussed in this paper: the Kizilirmak river delta on the Black Sea; and the tourism center of Erdek on the Marmara Sea. Coastal retreat on the Kizilirmak river delta is mostly attributed to decreasing sediment supply to the coast. The shore barriers and the enclosed lagoons are likely to respond readily to future sea-level rise. At Erdek, the most important threat is intrusion of salt water into freshwater systems caused by a combination of accelerated sea-level rise, land reclamation and overexploitation of underground aquifers.

Tersane bölgesi olmasi istenen Yalova-Altinova sahillerinin sismik Değerlendirmesi
Yalova İli, Altınova (Tavşanlı) bölgesinde, tarım, turizm ve iskan alanı olan yaklaşık 5 kilometrelik sahil şeridinin doldurularak tersane bölgesi yapılması planlanmaktadır. Kıyı alanlarındaki yanlış alan kullanımlarının uzun dönemdeki olumsuz etkileri bilinmektedir. Korumacılık-yatırım ikilemi, oluşturacağı çevresel sorunlar, kirlilik, zirai faaliyetler ve turistik boyut bakımından değerlendirildiği kadar, bölgenin deprem riski yüksek alanlar içerisinde yer alması nedeniyle yeraltı zemin sorunlarının da çözüm amaçlı olarak değerlendirilmesi gerekmektedir. Yer seçimi çalışmalarının geniş alanları kapsayacak şekilde jeolojik-jeoteknik etütler yapılarak yürütülmesi en iyi çözümdür. Yapısal özellik ve zemin koşulları yanında sıvılaşma potansiyeli ve olası sualtı heyelanları gibi riskler de belirlenmelidir. Bölgenin yapısal evrimi Permo-Triyas yaşlı metamorfik temel üzerindeki Neojen sonrası birimlerde gözlenir. İlgili deniz alanının sismik değerlendirmesini yapabilmek için deprem öncesi ve sonrası kaydedilmiş sismik veriler değerlendirilmiş, litolojik yapılar kestirilmiştir. Deniz içinde gözlenen faylar iki grup halinde değerlendirilmiştir. Birinci grup faylar Pleyistosen birimleri içinde kalmaktadır, güncel çökelleri kesmez fakat onları etkiler. Diğerleri ise normal bileşenli, güncel çökelleri de kesen küçük atımlı faylar olarak değerlendirilmiştir. Kocaeli 1999 depreminde İzmit Körfezi kıyı alanlarında yaşanan zemin sorunları ve bu çalışmada elde edilen deniz verileri, kıyı alanlarındaki zemin taşıma özelliklerinin belirlenmesinin önemini göstermektedir
