The Messinian Gulf is a geological feature located in the Mediterranean Sea, specifically in the region of southern Italy. It is part of the larger Mediterranean Basin and is known for its unique geological history, particularly during the Messinian Salinity Crisis, which occurred around 5.96 to 5.33 million years ago. This event involved significant changes in sea levels and salinity, leading to the formation of various sedimentary deposits. The gulf is bordered by several important landforms, including the Peloponnese peninsula to the west and the Calabria region to the north. Its waters are rich in marine biodiversity, making it an important area for both ecological studies and fishing activities. The Messinian Gulf also plays a role in regional climate patterns and ocean currents within the Mediterranean Sea.
