A quiet meeting of two worlds
occurs just below the surface of one of the
world's busiest ports Alexandria, Egypt
The water is murky. We're in the harbor. It's no deeper than 25 feet, but we can't see anything. There is no sewage treatment system in Alexandria, so every once in a while some foul thing floats towards us when the sluice gates are opened. This means it's very hard to find statues or columns even though they're probably close enough to touch. Each item that has been found is tagged with a marker buoy.
We were lucky enough to dive this unique site when visibility had substantially improved. The first thing we found was a finely-chiselled marble bust resting on the sandy bottom. Nearby, some paving stones and columns, a sphinx on its side, a statue, plinths covered in hieroglyphs and huge blocks of stone. Each dive on this vast site is an amazing experience and we felt the thrill of being some of the first people to see the remains of one of history's legendary palaces. A thrill that does not go away.
Farther east, off the coast of Israel, is the port of Caesarea, once ruled by King Herod. Appointed king of Palestine by Julius Caesar in distant Rome, the proud monarch built a city named after his emperor patron. The city survived for several centuries after Herod died and was a significant settlement in the eastern Mediterranean. When the sea is calm and clear, you can easily see the shape of the ancient city just offshore--a dark band in the water enclosing a huge area. Great blocks of stone are all that remain of the old port lighthouse, which was more than 1,650 feet from shore, truly an exceptional structure in those days.
All around the bay are dozens of pillars lying on their sides, remnants of the former city's beauty. Some of them are almost out of the water at low tide. Others are scattered to depths of about 40 feet. No need for air cylinders here. For most of this site, a mask and snorkel is all that's needed for a trip among the chunks of marble now covered with moss and seaweed. When the sea is calm, the water is extraordinarily clear and casts wonderful shafts of light on the mossy stones. Waterproof maps will help you keep track of where you are as you explore the vast site. A barely visible underwater rope links the main sections of the port, each marked with a numbered plaque that helps you envision the boundaries and shape of the ancient city.
Even after 20 years of excavations, the secrets of the old city are still being revealed. When Herod decided to build his big port here, one which could handle and shelter more than 100 ships, he created a small model town around it, with baths, avenues, a theater and a race track. They are all still here, at the water's edge, and you can easily imagine society women attending the chariot races in all their finery, and looking out across the sea beyond.
Herod was not the first person to have designs on the sheltered little bay. Up until the time of the Crusades, the city lived through successive occupations. All of them left their traces, including evidence of their daily lives. Every beach and every bit of land around Caesarea is stuffed with fragments, pieces of glass and mosaics. They are virtually on the surface, mixed in with the sand and the earth, ready to be picked up by anyone who simply cares to bend down. This is a place to feel 2,000 years of culture bearing down on you like no history book can.
Every year, during the June-July underwater excavation season, many items are brought to the surface by teams of divers--pieces of wood, jugs and fragments, glass bottles and bronze objects. Such items, found in the sea or on land, can be bought on the spot (once given a certificate of authenticity), and you can then have the pleasure of taking home an oil lamp or a woman's hair pin from the time when King Herod ruled Palestine.
The Greeks and their widespread Mediterranean civilization have also left remains under the sea, but they are seldom explored because of strict rules in Greece about archaeological diving. But at Pylos, in the far south of the Peloponnesus, I was able to examine a couple of wrecks. The striking thing, as with sunken cities, is that most of the remains are only ten feet under and accessible to all--even without tanks.
About 10 minutes by boat from the village, we arrived at a site littered with the sunken remains of the unlucky merchant vessels that never reached their destination: a little island inhabited only by a few wild goats and surrounded by rocks. It was these that sank the two ships on which we dove; two ships which lie only 165 feet apart. In this perilous region of jagged coastlines, where gales rise strong and appear suddenly, ships rarely had time to avert disaster, inevitably smashing into an outcropping just below the surface, sinking immediately and scattering their precious cargo across the sea bottom.
The site was discovered in 1953, but since then only a few Greek experts have been allowed to visit it. Beneath the sea, in crystalline waters, jumbled granite columns stick up among the rocks. They are huge, mostly intact, and date from the first century A.D., possibly from the great portico King Herod built at Caesarea. The Venetians destroyed it in the Middle Ages and apparently wanted to take some of it away with them. But the boats carrying the booty sank en route. However, this is just one theory. The only sure thing is that the granite comes from the Egyptian city of Aswan. The sarcophagi, which are older, date from the third century B.C. and are scattered on the sea bed only 24 feet down.
Dimitri Haniotis, head of the Underwater Antiquities Department in Athens, is planning to open the site to the public. But this is an ongoing project and ways must be found to keep the site as undisturbed as possible. Sea grass, the Mediterranean's ecological 'lung,' is thick and untouched here so measures are needed to protect it, as well.
There must be hundreds of thousands of amphoras, pear-shaped vessels for carrying wine, food, salt, herbs and other goods for sale, all over the Mediterranean. Most are too far down and so would normally be inaccessible, unless you replace human divers with machines. This was done in 1996 by Comex, France's main underwater operations company, and by DRASSM, the French government's underwater archaeology department, at a wreck of an amphora ship in the bay of the southern French port of Marseilles. Although it had nearly reached its destination to deliver its cargo some 2,000 years ago, it sank in 200 feet of water, just outside the port.

We stay in permanent contact with the Minibex mother ship on the surface through an ultrasound telephone. Super Achilles, a remote-controlled robot linked to the surface, films us amid the amphoras. Its operator is on the bridge of the Minibex more than 230 feet above us. An ancient wreck, a super-modern submarine and a robot circling around us--a curious marriage of eras.
We are entering the world of diverless exploration. The expedition is an experiment, to come up with ways to work at greater depths. So each day, the team has to innovate and adjust working methods. Every morning, we set out from the port to the site. The Minibex takes up its position using a device that keeps it stationary over the wreck. The Remora 2000 is swinging on its gantry. The tide is going out, so the submarine must get into the water quickly. The leader of the expedition is on board this day. He has already seen the amphoras on the video screen and is going down for the first time.

Apart from the historical aspect, this kind of exploration also helps refine techniques that are little used, such as photogrammetry. This enables a site to be pictured in 3-D and then studied on a computer screen.
Each day, new pottery shards are found. Using machines, they can be collected without damaging them or disturbing the physical arrangement of the cargo. Opening the door to a whole new range of wrecks, this kind of exploration is the future of marine archaeology--a delicious contrast between high-tech and antiquity.
Countless wrecks and sunken remains are waiting to be discovered in the Mediterranean. Techniques may change, but the discoverers and the diggers dream the same dreams they always did. A few even say the mythical lost city of Atlantis is somewhere in the middle of the Aegean Sea. If it is, I hope to explore it one day. Better yet, I hope to discover it.
