Monna, Stephen. (2005). Hydrophone dataset (OAS E-2PD @ 100 Hz) from INGV/NEMO-SN1 seafloor platform during GNDT-SN1 project in Western Ionian Sea site (East Sicily), part of EMSO network.
No full textThis digital database comprises data recorded from the hydrophone during the GNDT 2 project. The hydrophone was installed on the frame of the GEOSTAR deep-sea multidisciplinary observatory, deployed offshore of the Eastern coast of Sicily (Southern Italy) at a depth of 2065 m.The sensor was connected to a 24 bit digitizer, and its time reference came from an external rubidium clock connected to the digitizer, and synchronized with the seismometer. As this site is of great interest given its proximity to the Etna volcano (~ 50 km) and to important offshore seismogenic structures, the main purpose of the hydrophone is to record seismic data in combination with the seismometer
Marinaro, Giuditta. (2005). Transmissometer dataset (Ctg Alphatracka II @ 1 sample / hour) from INGV/SN-2 seafloor platform during MABEL project in Weddell Sea site (Weddell Sea), part of PNRA network.
No full textAlphatracka MKII is a transmissometer monitors the total suspended matter in water by measuring the beam attenuation coefficient alfa at 660 nm. Transmissometer provides information about possible suspension of particle matter due to bottom currents. The time-series is complete and continue through all period of measurement, without gap of data or relevant sensor problem
Monna, Stephen. (2005). Seismometer dataset (Guralp CMG-1T @ 100 Hz) from INGV/NEMO-SN1 seafloor platform during GNDT-SN1 project in Western Ionian Sea site (East Sicily), part of EMSO network.
No full textThis digital database comprises seismological data recorded during the GNDT 2 project by a 3 component broadband seismometer, together with a hydrophone. The sensor was installed on the GEOSTAR deep-sea multidisciplinary observatory, offshore of the Eastern coast of Sicily (Southern Italy) at a depth of 2065 m. The seismometer is installed in a dedicated vessel integrated in a separate structure connected to the observatory via a special mechanical release. To guarantee a good coupling with the sea bottom, the structure is disconnected just after the observatory touch-down and kept linked to the frame by a slack rope (Favali et al., 2006). The sensor was connected to a 24 bit digitizer, and its time reference came from an external rubidium clock connected to the digitizer. This project is a continuation of GNDT 1 where the main objective was to establish a multiparameter seafloor observatory off-shore eastern Sicily. Long-term broad-band seismic measurements from this site is of great interest given its proximity to the Etna volcano (~ 50 km) and to offshore seismogenic structures where some of the most destructive earthquakes, some of which accompanied by tsunamis, have occurred in Italy
Lo Bue, Nadia. (2005). CTD dataset (SBE 37-SM @ 1 sample / 10 min) from INGV/NEMO-SN1 seafloor platform during GNDT-SN1 project in Western Ionian Sea site (East Sicily), part of EMSO network.
No full textThe dataset contains sea bottom Conductivity, Temperature and Pressure data (about 1 m above the bottom) acquired through a SBE 37-SM installed on SN-1 station. The collection period ranges from January 2005 through April 2008. CTD has been used in order to monitoring possible variations of bottom sea water masses in the area
Marinaro, Giuditta. (2005). CTD dataset (SBE 16 @ 1 sample / hour) from INGV/SN-2 seafloor platform during MABEL project in Weddell Sea site (Weddell Sea), part of PNRA network.
No full textThe dataset contains sea bottom Conductivity, Temperature and Pressure data (about 1 m above the bottom) acquired by SBE 16 SEACAT. CTD is used in order to monitor possible variations of bottom sea water masses in an area interested by the mixing of different water masses. The series is complete and continue through all period of measurement, without gap of data or relevant sensor problem

Lo Bue, Nadia. (2004). ADCP dataset (RDI WorkHorse 300 kHz @ 1 profile / hour) from INGV/GEOSTAR - SN-3 seafloor platform during ORION-GEOSTAR3 project in Southern Tyrrhenian Sea site (Marsili Basin), part of ORION network.
No full textThe Acoustic Doppler Current Profiler measures the water velocity using the physical Doppler shift principle. The transducer generates a pulse of sound at a known frequency that travels through the water and is reflected in all directions by particulate matter (e.g., sediment, biological matter, bubbles). Some portion of the reflected energy travels back at the transducer where the processing electronics measure the change in frequency. The Doppler shift measured by the transducer reflects the velocity of the water along the axis of the acoustic beam. The ADCP operates using three transducers generating beams with different orientations relative to the water flow then the measured velocity by each ADCP transducer is the projection of the 3D velocity onto the axis of its acoustic beam
