摘要电火花震源作为一种海洋地震震源，其成功与否主要取决于水的物理特性。在淡水或准淡水湖泊中，需要一些额外的技术。对于伊兹尼克湖的基本和新鲜沃茨，我们设计并尝试了一种特殊的电火花容器和一些新的电极阵列配置。文中还讨论了一些技术问题.单电极传感器的情况下，这意味着通过它放电的能量将高出许多倍，如果相比多电极的情况下，被发现是最实用的这个特定的探险。事实上，即使垂直分辨率降低了约2.5-3倍，它也是相当成功的。获得的浅层地震剖面被用来成像在湖的地层和构造环境。两个不整合的主要地震单元，这是由一个主要的侵蚀面30-35米以下的水面，可以检测到的水下河流-lecustrine沉积。
Abstract The success of a sparker, a marine seismic energy source, would mainly depend on the physical characteristics of the water. In fresh or quasifresh lakes, some extra technologies are needed. For the basic and fresh waters of Lake Iznik, we have designed and tried a special sparker container and also some new electrode array configurations. The results some technical problems encountered will be discussed. Single electrode transducer case, which means that the energy discharging through it will be many times higher if compared to the multi-electrode case, was found to be most practical for this particular expedition. It was in fact rather successful even the vertical resolution decreased about 2.5-3 times. Obtained shallow seismic profiles are used to image the stratigraphic and tectonic setting in the lake. Two unconformable main seismic units, which are separated by a major eroded surface 30-35 m below water surface, could be detected in the sub-surface fluvio-lecustrine sediments.
