2001年7月的一天,太阳刚刚从东方地平线升起,“公主”号科研船上的船员们就开始忙碌起来。他们工作的这片海域离埃及海岸有4英里(相当于6436米)。在水下30英尺(相当于914.4厘米)处,潜水员们正在一片覆盖着一层厚厚淤泥的瓦砾中来回穿梭着,这片瓦砾堆是一座古代名城——赫拉克勒昂城的遗迹。这座城市就像大西洋中的一些神秘岛屿一样,在1300年前突然消失在地中海中。 One day in July 2001, the sun had just risen from the horizon of the East and the crew of “Princess” research ship began to get busy. The sea they work for is 4 miles (equivalent to 6,436 meters) off the coast of Egypt. At 30 feet below sea level (equivalent to 914.4 centimeters), divers are shuttling back and forth through a layer of thick mud covered with rubble, an ancient city known as the remains of Heraklion. Like some mysterious island in the Atlantic, the city suddenly disappeared in the Mediterranean 1300 years ago.
