Description
We have designed and built an underwater measurement system, PORFIDO (Physical
Oceanography by RFID Outreach) to gather oceanographic data from the Optical Modules
of a neutrino telescope with a minimum of disturbance to the main installation.
PORFIDO is composed of a sensor glued to the outside of an Optical Module, in contact
with seawater, and of a reader placed inside the sphere, facing the sensor. Data are
transmitted to the reader through the glass by RFID and to shore in real time for
periods of years. The sensor gathers power from the radio frequency, thus eliminating
the need for batteries or connectors through the glass.
We have deployed four PORFIDO probes measuring temperatures with the NEMO Phase 2
tower in april 2013. The four probes are operative and are transmitting temperature
data from 3500 m depth.
