The study of water intrusions into the Black Sea(BS) from the Mediterranean(MS) and Caspian(CS) seas dates back to the end of the I9th-beginning of the 20th centuries. While studying outcrops on Capes Chauda and Karangat,and on the Kerch-Taman Peninsula, Andrusov (1884,1889,1904-1905, 956) discovered that the former contained CS molluscan species while the latter contained those from the MS that do not live today in the BS.Based on these findings,he suggested that these outcrops were formed on the bottom of the BS during periods of CS and MS water intrusions,and later,they were exposed due to tectonic uplift.Indeed,similar sediments were found on the BS bottom in the course of the earliest marine explorations, dating to 1890-1891,by the Black Sea Fleet's R/V "Chernomorets" (Andrusov, 1890; Murray, 1900) that were continued under J.M. Shokalsky (hydrology) and A.D. Arkhangel'sky (sedimentology) using a new,improved corer of 6 m length on the R/V "Pervoe Maya" between 1925 and 1927,and then on the R/V "Pervoe Maya" and R/V "Hydrograph" between 1928 and 1933.Based on the results of these marine campaigns along with onshore geological investigations,the geological history of the Black Sea was described,the first stratigraphic scheme for the Quaternary was developed,and the time and direction of MS and CS intrusions into the BS via the connecting straits,e.g.,the Bosphorus—or the Izmit-Sapanca-Adapazari or Sakarya-Bosphorus (Pfannenstiel,1944)—and the Manych,respectively,were reconstructed (Arkhangel'sky and Strakhov,1938).The initial stratigraphic scale was detailed using mollusks as the main paleontological tool (e.g., Nevesskaya, 1965; Fedorov, 1978).
