The wreck of Titan

Titan sank off the eastern tip of the island Levant. He set up the Office for Protection of Monuments Provencal with recreational and professional divers starting in 1954 for research. An important role was played here Taillize P., who was director of underwater work. One can say that the methods used here were more scientific than previous ventures. Prior to exploration located in the 1927-1929 m of the wreck, made drawings and photographic documentation of the position. Removal of the layers were made using the ejector from which the material entered the appropriate screen on the research vessel. All items are described and cataloged on an ongoing basis, with reference to their position in office. For the items were recovered from the wreckage, among others. 700 amphorae (Dressel type 10 and 12) containing traces indicating that the cargo was cured fish, and besides, the platters, tiles, two vases, coins, dzbanuszki olpées and bone fragment, possibly of human origin. Monet interpreted as a votive, found in the place were the mast, let wydatować unit on the first century BC The exposed part of the wreck (with dimensions of 20 x 4 m) was agreed to raise the bottom, for this purpose przepołowiono it into two parts. On the surface of the individual pieces were placed in boxes with sawdust, it did not protect them from destruction, however. By some excavations at the wreck of Titan have been called the first scientific exploration of the submarine on the sea waters.

The wreck from Grand Congloué

The wreck discovered in Grand Congloué be between 1935 to 1945 m depth. His tested addressed the group of divers under the supervision of conservators from Provence prof. Fernand Benoit. The work started in 1952, also attended by JY Cousteau and F. Dumas. It is in this position was first used ejector, this device had a diameter of 120 mm, and his departure led to board the research vessel Calypso. There, the material was screened and checked for any small artifacts. Diving as a place from 2 to 3 times a day and lasted 18, 15 and 12 min. When the work was unveiled keel 50 x 75 cm. Among the items discovered were, among others., More than 2.5 thousand. amphoras and more than 6 thousand. pieces or fragments of pottery in general. It was established after testing a hypothesis attributed to a ship journey from Delos, the Rhodes and the Cyclades, and Sicily Campaign to crash off the coast of Marseille. After 25 years of studies on material obtained from the excavations, the experts said that the position in fact consisted of two wrecks, which sank in the same place. The first wreck wydatowano the second century BC, its cargo consisted of about 400 amphorae of wine, the Greco-Roman origin, and about 7 thousand. fragments of dishes from the Campania region. The second wreck wydatowano the end or the beginning of the second century BC, it consisted of over a thousand amphorae of wine, Roman origin, defined as the type of Dressel 1A. Recent studies have shown that the amphoras from the wreck No. 2 comes from Cosa in Etruria - today's Tuscany.

The beginnings of submarine research in the Mediterranean

Until recently, the first archaeological project to explore the nature of the position of an underwater marine, mining was considered one of the ancient statues of cargo ships into the island flooded Antikithirą (Greece) and near the town of Mahdii (Tunisia). Commonly these shares is called research, but be aware that their conduct had nothing to do with archaeological research, in today's sense. They consisted mainly on the extraction of cargo in the form of sculptures, in which documentation was not performed, and pieces of the hull of the ship had been destroyed. Its cargo unit has proved very valuable for archaeologists, art historians, museum. Because they contained valuable antique statues, or their copies, including those made of bronze, which were not previously known from terrestrial stations. The actions of those used sponge divers - who were also the discoverers of the wreck - and supervise their work, archaeologists from the deck of the ship. From the wreckage of a sunken into Antykithyrą, acquired several pieces of wood sheathing, which have been archaeological analysis, however, due to their poor state of preservation did not produce reliable data.

Underwater archeology

Information about the oldest examples of human descent in the deep sea, from ancient times. In almost all they relate to this type of projects by the campaigns of war or for recovering marine resources - such as sponges, pearls. Notes on this subject were, among others. Pliny the Elder in the works, Thucydides, Wegecjusza, as well as Homer's Iliad.
More information about attempted landing in the deep sea produce contemporary sources from the sixteenth and later centuries. This period was a time of great maritime and colonial expansion, many European countries. The most common means of transport as much military and civilian vessels were then. Many of them were wrecked by acts of war or of destructive weather. Shares extracting precious cargo took place in the Mediterranean, Baltic, and also in the "New World". Usually, when they used a primitive diving bell, and the items were extracted blindly. The most important goal was to recover - to save as much valuable cargo and armaments.
It's hard to talk about the first dives, or zejściach man in the deep sea in order to raise the archaeological material, as a marine area that each has its pioneers. However, you can safely assume that the first intentional underwater archaeological excavations in Greece have been organized in 1885 by Christos Tsoundasa, conservator in Athens. Had a diagnosis of the nature of the underwater and related to the Gulf Salamińskiej together with the place of the battle of Salamis. Apart from isolated finds, they have not yielded the most interesting discoveries, and had no greater importance to the wider underwater archeology. You can even say that was quickly forgotten.

New planetary system

Astronomers have discovered a planetary system only two thousand light years away from Earth. Sensational data was provided by the American Kepler telescope. The system comprises of six planets, all are greater than two to almost five times from Earth, and are greater than the mass of the earth from two to thirteen times.
