Approximately 100 scientists have revealed that more than 800 thousand whales and dolphins live in the Mediterranean and Black Sea, with a 5-year study. In the study, in which 10 planes and 6 research ships were used, data on other marine creatures such as sea turtles, stingrays, sharks, seabirds and marine litter were also collected.
In the project, which aims to determine the amount and distribution of species under protection today and to evaluate the threats against them, the effectiveness of the 20-year conservation efforts of the relevant countries could also be measured. Within the scope of the project, both visual and acoustic monitoring methods were used in the researches, while the first large-scale marine megafauna monitoring surveys of the Mediterranean and Black Sea were conducted in 2018 and 2019.
TURKISH SCIENCE PEOPLE ALSO PARTICIPATED
In the research supported by the Turkish Marine Research Foundation (TÜDAV) as researchers and logistics, around 100 scientists from ACCOBAMS countries, as well as 10 specially equipped aircraft, 6 research ships and many institutions and organizations worked together. In the project, data on dolphins and whales, as well as other marine creatures such as sea turtles, stingrays, sharks, seabirds, and marine litter could be collected.
After two years of comprehensive analysis of the data obtained, the results were presented online today on the internet. The international event brought together more than 250 participants, including scientists, administrators, politicians and NGO representatives, who are dedicated to the conservation of sensitive marine ecosystems and endangered species.
FROM THE RESEARCH RESULTS
The aerial surveys covered 1.92 million square kilometers, which accounts for 77 percent of the Mediterranean. 22,652 individuals were recorded in 1,672 dolphin and whale observations made from the air. In the surveys conducted by boat, 2,939 dolphins and whales were recorded in 385 observations in 52 percent of the Mediterranean with 1.3 million square kilometers. Based on this, it was announced that there were more than 600 thousand dolphins and whales in the Mediterranean.
With air surveys, an area of 270 thousand square kilometers covering more than 60 percent of the Black Sea was scanned. In 1984, a total of 4688 individuals belonging to 3 dolphin species found in the Black Sea were recorded. Based on this, it was estimated that there are more than 235 thousand individuals in the Black Sea.
“WE ARE VERY EXCITING AND HAPPY”
“Today, population abundances of census and estimates of marine mammals living in this region have been announced. With the ASI and CeNoBS projects, we counted the dolphins and whales in the region with the participation of approximately 10 aircraft, 6 sea vehicles, and more than 100 scientists in the Mediterranean in 2018 and Black Sea in 2019. Today, the final finale of this long run is the conclusion. The results of our work were announced at the meeting held online with the participation of approximately 250 people from all over the world. We are very excited and happy. According to the project results, it is estimated that a total of 800 thousand dolphins and whales live in the whole Mediterranean and Black Sea from the Strait of Gibraltar to the Suez Canal. “
