The Gulf of Sidra is part of the Mediterranean Sea and is located on the northern coast of Libya. It is also known as the Gulf of Sirte. The sea has a surface area of 57,000 km2 and runs from Misrata to Benghazi. Its shore consists of desert with salt marshes and flats scattered along the coastline. The waters in the gulf can reach up to 31 °C during the summer, making it the warmest in the Mediterranean. The gulf is important for tuna fishing as well as sponge collecting. The Gulf became infamous in the 1980s due to Libya’s unsanctioned expansion of their territorial waters.
