2 pi-Samis were deployed at the vent site Chiane del Lume (Ischia) for 1 week at a depth of 10 m. They were deployed 1 m above the seafloor and attached to the rock. CO2 vent sites are characterized by high pH variability associated to the vent intensity; thus, the reason of this deployment was: 1) to test that the pi-Samis worked correctly and 2) to see small scale pH variability to better decide which position will be the best for long term deployment.
2 temperatures are measured: temperature exterior, temperature IntEnd. I need to double-check the correct one.
In addition, when we were preparing the instruments, we realized about a issue with the inlet filter covered by a copper mesh, which dificults water pumping. We are working with this issue and we already contacted Reggie (Sunburst)
