With Waters at 32C, Mediterranean Tropicalisation Shifts Into High Gear
The venomous lionfish population has surged to 15–20 individuals per dive near Antalya due to record-high Mediterranean temperatures disrupting native marine life.
- Last week, Mercator Ocean International data showed the Mediterranean Sea recorded its warmest July on record at 26.68C.
- This year off Antalya, divers recorded nearly 32C surface temperatures, with Draman noting 'We were at a depth of 30 metres this morning and the water was 29C.'
- In the eastern Mediterranean, invasive lionfish are now thriving as hundreds of Red Sea species moved through the Suez Canal due to warming waters.
- Invasive species disruption is worst in the eastern Mediterranean, where many native species have disappeared due to warm waters and competition, explained Professor Gil Rilov.
- Through the Strait of Gibraltar tropicalisation could spread in the coming years, and a PNAS study warned the Mediterranean could be entirely tropicalised by 2100.

With waters at 32C, Mediterranean tropicalisation shifts into high gear
When Murat Draman went scuba diving off the coast of the southern Turkish province of Antalya and saw the temperature in the depths was pushing 30C, it didn't surprise him.
The temperature of the water surface is higher than the seasonal averages near the French coast. The same phenomenon occurred at the end of June, with a temperature record set for this period. This warming attracts species from the Red Sea, which come in competition with local species. - The Mediterranean warms up: what effects on local species? (Environment).
