A grant from UNESCO was awarded to Abu El-Saadat in 1968 to outline the architectural remnants on the ocean floor, with a particular emphasis on what may possibly be a piece of the Pharos of Alexandria. According to Underwater Archaeology in Egypt, Vladimir Nesterov and Honor Frost were also summoned by the Egyptian authorities, and the three of them put together a list of 17 different lighthouse seafloor fragments. Frost pointed out that the figure would multiply one hundred times if they conducted a thorough investigation. The coastal region around Alexandria was declared a military zone as a result of the war being fought between Israel, Egypt, Jordan, and Palestine, according to UNESCO, forcing the suspension of archaeological studies. The study by Abu El-Saadat, Frost, and Nesterov still laid the framework for eventual excavations of the sites despite the delay.
