Magmatic Signature in Submarine Hydrothermal Fluids Vented Offshore Ventotene and Zannone Islands (Pontine Archipelago, Central Italy)

Figure 3

Sampling system for the bubbling gases off Zannone (depth in the range of 120-150 m bsl). The ROV was equipped with a homemade sampling system composed of four small funnels connected to 240 ml serum-type bottles. The system, fitted to the front of the ROV, allows to collect bubbles by placing the funnel on the venting gases (see text for more information).
