项目摘要

Recent marine electromagnetic measurements yielded the delineation of a 30 km long and at least 3 km wide fresh groundwater body within the deep-seated sub-seafloor aquifer offshore the southern coastal plain of Israel. The results allowed an estimation of unexploited fresh groundwater. However, due to the low resolution of the applied geophysical methods, the results turned out insufficient in order to fully understand the hydrogeological configuration and mechanism controlling the occurrence of this discovery. Especially the lateral geometry of the freshwater body, important for the hydrogeological modeling, could not be resolved. Without such an understanding, a rational management of this unexploited groundwater reservoir is impossible.The proposed project aims at answering the hydrogeological boundary conditions of the fresh groundwater body by implementing for the first time worldwide a high-resolution electromagnetic method based on the application of a Circular Electric Dipole (CED) in the marine environment regarding groundwater studies. In addition to the development of the transmitter antenna, the development of an interpretation scheme (e.g. 1D inversion and 2D/3D forward modeling) for this novel electromagnetic technique will be the main focus of the project. Based on the results of the geophysical study, a management scheme for future usage of this groundwater resource can be developed.The research will result in an increased potential of fresh groundwater resources in Israel and in the development of a new high-resolution marine electromagnetic technology, which can be applied worldwide not only for submarine groundwater but also for hydrocarbon and gas-hydrate exploration. Theoretical model studies with synthetic data have shown that the MCED technique has a better lateral resolution of the resistive groundwater layer compared to the conventional marine Long Offset Electromagnetic (LOTEM) technique using the inline/broadside configuration

最近的海洋电磁测量结果在深层座位的层状含水层含以色列的南部沿海平原上列出了30公里长，至少3公里宽的新鲜地下水体。结果允许估计未开发的新鲜地下水。但是，由于应用的地球物理方法的分辨率很低，因此结果不足以充分了解控制该发现发生的水文地质配置和机制。尤其是淡水体的侧向几何形状，对于水文地质建模很重要。没有这样的理解，就不可能对这种未开发的地下水储层进行合理的管理。拟议的项目旨在通过在全球范围内首次实施基于在陆上水域中的圆环环境（CED）的应用。除了开发发射机天线外，该新型电磁技术的解释方案（例如1D反转和2D/3D向前建模）的开发将是该项目的主要重点。根据地球物理研究的结果，可以开发出一种用于未来使用该地下水资源的管理计划。该研究将导致以色列新鲜地下水资源的潜力增加，并开发了新的高分辨率海洋电磁技术，该技术不仅可以在全球范围内应用于潜艇地下水，还可以用于氢碳和加油和加油和加油和加油。使用合成数据的理论模型研究表明，与传统的海洋长偏移电磁技术（Lotem）技术相比，MCED技术的电阻地下水层的横向分辨率更好
