“…Furthermore, epicentral distribution of the earthquakes between 1985-1997 (recorded by the stations of the Earthquake Research Institute) in the area between Adapazar and Karasu indicates the presence of NE-SW-trending lineaments reaching to the Black Sea ( Figure 9A). The presence of NNE-SSW-trending faults, which cut the Black Sea shelf at a high angle, is also supported by offshore seismic profiles (Figures 8, 9) (also see Algan et al 2002).…”

“…There is a submarine canyon that extends to 1500-2000 m depth in the Black Sea in front of the Sakarya River. This canyon cuts the shelf deeply and has steep walls (Erinç 1958;Algan et al 2002). Multichannel seismic reflection data are utilized to see if the faults extend under the water of the Black Sea in the Sakarya River offshore.…”

“…The variation in dip directions and the tilting of strata across the faults represent the strike-slip nature of these faults. In addition, the faults 5, 12 and 15 might have been E-W-trending oblique-slip dextral faults with normal neotectonic features of eastern marmara, turkey 191 components that caused the subsidence of the northern block of the Kefken-Akçakoca Coastal Zone and the lateral displacement of the submarine canyon axis (Algan et al 2002).…”

Eastern Marmara region consists of three different morphotectonic units: Thrace–Kocaeli Peneplain (TKP) and Çamdağ–Akçakoca Highland (ÇAH) in the north, and Armutlu–Almacık Highland in the south of the North Anatolian Fault Zone (NAFZ). The geologic‐morphologic data and seismic profiles from the Sakarya River offshore indicate that the boundary between the TKP in the west and ÇAH in the east is a previously unrecognized major NNE–SSW‐trending strike‐slip fault zone with reverse component. The fault zone is a distinct morphotectonic corridor herein named the Adapazarı–Karasu corridor (AKC) that runs along the Sakarya River Valley and extends to its submarine canyon along the southern margin of the Black Sea in the north. It formed as a transfer fault zone between the TKP and ÇAH during the Late Miocene; the former has been experiencing extensional forces and the latter compressional forces since then. East–West‐trending segments of the NAFZ cuts the NE–SW‐trending AKC and their activity has resulted in the formation of a distinct fault‐bounded morphology, which is characterized by alternating E–W highlands and lowlands in the AKC. Furthermore, this activity has resulted in the downward motion of an ancient delta and submarine canyon of the Sakarya River in the northern block of the NAFZ below sea level so that the waters of the Black Sea invaded them. The NE–SW‐trending faults in the AKC were reactivated with the development of the NAFZ in the Late Pliocene, which then caused block motions and microseismic activities throughout the AKC.

“…The Sakarya River, which is one of the largest rivers in Turkey, discharges into the Black Sea and has a drainage area of 56.504 km 2 and a length of 824 km (Algan et al 2002). The discharge rate of the Sakarya River is 5.6 km 3 yr -1 and is influenced by the Marmara regime (average rainfall is about 770 mm yr -1 ) (Koçman 1993, Işık et al 2008.…”

The aim of this study was to determine the spatial and temporal variation of phytoplankton and water quality in response to the hydrological regime in an isolated floodplain lake (North Mollaköy Lake) of the Sakarya River. Variations in the composition, biomass and functional groups of phytoplankton and environmental parameters were monthly analyzed in subsurface samples collected from the pelagic zone at four stations from July 2012 to June 2013. A total of 109 taxa were identified, and the species which contributed the most to the phytoplankton biomass were grouped into 14 functional groups (FGs). The distribution of FGs was linked to the transition (T1 and T2), high (HW) and low (LW) water periods in North Mollaköy Lake. FGs J, MP, N, G, X1, X2, Y, W1, W2, S1, H1, B and C were the contributors to the phytoplankton biomass during the low-water period (LW) and the transition periods (T1 and T2), while Lo contributed the most during the high-water period (HW). RDA revealed that the most important factor affecting the temporal distribution of FGs was the water discharge and that there are
