A recent study published in the journal PLOS One shows the results of new methods of calibration of radiocarod applied to Cyrian crash.
This former Greek trade ship was discovered in 1965 off the coast of Cyprus Diver Andreas Cariola, who, in search of lips, discovered a shipwreck that is considered one of the most important conclusions for understanding navigation in antiquity.
In addition, on the seabed there were more than a hundred amforts located next to the boat about 14 meters long, equipped with a square and manned mast, according to researchers, four sailors.

Conclusions that struck scientists about the Greek ship
In the period from 1968 to 1969, 391 amphoras containing products such as wine, olive oil and almonds found archaeological excavations. The data indicate that the last trip of the ship took about 300 AC, but this date does not coincide with the radiocarbon dating of shipwrecking samples.
Decades after its initial withdrawal, the team from the University of Cornell questioned the established chronology, concluding that the shipwreck occurred several years later than it was considered.
In previous studies, the chronology of shipwreck was based on dating ceramic and numismatic objects restored during excavations. Nevertheless, the new research group used modern methods, such as radiocarbon dating and dendrocronology, which analyze the growth of the wood ring used in the construction of houses or boats to consider this chronology.

“We are pleased to apply scientific methods to date of the famous ship in Cyrenia a little more than 2300 years ago. This is important for the history of military -marine technologies and naval trade in the classic Mediterranean, ”the author said.
He also mentioned that the methods used to meet with the ship and solutions to several technical problems that they have encountered, “will now help to meet with other shipwrecking and better inform the history of the old navigation.”
Saferagio del Kyrinia: when she sank, according to the investigation
The researchers determined that the collapse of Cyrian occurred between 296 and 271 AC, in particular between 286 AC and 272 AC during the study, scientists are faced with the call of polyethylene glycol (PEG) used to maintain the remains of the helmet and, which impede the methods of radio sarbon and dendrocronology. After eliminating the PEG, they received more accurate data on the date of immersion of the boat.
Researchers have determined that the international radiocarbon calibration curve for the Northern Hemisphere was not updated during the period between approximately 400 and 250 changes to improve the chronological accuracy of the remains of the old structures, they returned this curve using samples of other types of trees, which is a significant progress in chronological studies.
