Mediterranean increasingly warm: record temperatures and jellyfish

We are now facing a real tropicalization of the Mediterranean Sea which is leading to a too rapid and rapid change of this ecosystem, so we are increasingly witnessing an invasion of alien species, explosions of mucilage and toxic algae, a decrease in native fish species, a reduction in fishing and catches and, as can be seen from these images, a proliferation of jellyfish ...

Also in this year we are witnessing the now common and usual phenomenon of the inflorescence of marine mucilage along the coasts of our sea. At the same time as the mucilage, however, an excessive proliferation of the microalgae Ostreopsis cf. Ovata.

This video was taken last Saturday (14/10/2023) during an inshore dive at about 15 meters deep. I mention the precise date because during the canonical 3 minutes of decompression at a depth of 3 meters hanging from the chain of one of the "safe water" signaling buoys, about 200 meters from the rocky and jagged coast, I decide to check the temperature of the water and the computer measured 25°C. ...

Mnemiopsis leidyi invasion

And also this summer we found ourselves faced with the now regular invasion of the Sea walnut, Mnemiopsis leidyi (warty comb jelly or sea walnut). This phenomenon is becoming more and more frequent throughout the summers, and it is now clear that the main cause of these invasions is the increase in sea temperature. ...
