When the sea level was a few hundred feet lower during the Ice Age, the Gulf of Suez was a small river (the lower wadi Tumilat) affected by the ocean tide up from the Red Sea, the southern one-third of the Red Sea which was dry land with the flow from the north going through it and out into the Gulf of Aden, yet the Gulf of Aqaba (east of the Gulf of Suez) was deep, fully oceanic during the Ice Age.
