Shallow-water Hydrothermal Vents in the Gulf of Naples: Geochemistry and Microbial Diversity
Introduction Shallow-water hydrothermal vents, situated below 200 meters in tectonically active regions, are dynamic ecosystems where fluid chemistry and geology intersect to shape microbial life. In the Gulf of Naples, Italy, two underwater volcanic regions present distinct geochemical signatures influenced by their hosting structures: one under the Somma-Vesuvio volcanic system and the other within the…
