Scientists from the Russian Federation reported that the water level in the Black Sea has risen by 3.8 m in 2.4 thousand years. It was possible to determine this due to the study of the ruins of the city of Acre, which in the 4th century BC. existed on the Kerch Peninsula.
Viktor Vakhoneev from Sevastopol State University told TASS that there were several settlements off the coast of Crimea and Kuban, created by the Greeks during their colonial travels. At present, they are completely or partially under water after a number of natural processes. The location of most of it has been known for a long time, but modern technologies annually allow more data to be obtained as part of the study of new objects.
At present, a number of submerged settlements in the Northern Black Sea region are being studied. Scientists report that they searched for Acre for about 150 years and succeeded only in the 1980s, since only a tenth of the city remained on land. The settlement was created on a small promontory that deeply flows into the strait, and on the side of the coastline there was a protection in the form of a stone wall. Today the bulk of the structure is flooded with water. In 2019, archaeologists examined the entire length of the flooded part of the wall and were able to determine which part remained in the sea and where the coastline ran.
As a result, it was possible to establish that the waters of the Black Sea over the past 2.4 thousand years have risen by 3.8 m. Vakhoneev noted the possibility of calculating the dynamics of changes in the maritime boundary for individual regions. This is of great importance for archaeologists, since it allows them to clarify the outlines of settlements that existed in antiquity, and will also help in finding objects that have not yet been found.
