摘要

一项海洋地球物理调查是在古代尤诺斯托斯港的废墟上进行的,在亚历山大港最近的西部港口前面。该调查工作旨在利用侧扫声纳和海底剖面仪研究调查区域的海底和次表层。试图确定自然和地质灾害对水下古港海岸的影响。在侧扫声纳的声学图像上发现了保护港口不受北方巨浪影响的众多山脊、珊瑚礁和防波堤。除了一些未定义的人工制品和古老的海岸伤痕外,人们还在海底发现了一些痕迹。地震解释也显示了一系列的浅层衍射,通常向东和向北增强。此外,在沉水古港区下方还发现了变形和扰动的地下地层。侧扫声纳和水下剖面的发现与古代文献的描述一致,成功地证实了古代沿海港口对自然灾害的脆弱性。

Marine geophysical surveys and interpretations on the ancient Eunostos harbor Area, Mediterranean Coast, Egypt

A marine geophysical survey was carried out over the ruins of the ancient Eunostos harbor, in front of the recent western harbor of Alexandria. The survey works aimed to study the seafloor and the subsurface layers over the survey area using side-scan sonar and sub-bottom profiler. It is attempted to identify the impact of nature and geo-hazards on the coast of the submerged ancient harbor. Numerous ridges, reefs and breakwaters which protected the port from the northern swells were detected on the acoustic images of the side-scan sonar. In addition to some undefined artifacts and ancient coastal scars were noticed across the seafloor. Seismic interpretations also showed series of shallow diffractions that generally intensified towards east and north. Also deformed and disturbed subsurface layers were noticed beneath the area of the submerged ancient harbor. Side-scan sonar and sub-bottom profiler findings are concordant with the descriptions of the ancient literature and succeeded to confirm the vulnerability of the ancient coastal harbor to natural disasters during the past times.

期刊介绍: Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
