<p><b>Period:</b> October 12, 2019 - on going</p>
<p><b>Abstract:</b> The 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.</p>

<p><b>Abstract:</b> This sensor measures the hydrostatic (water column) pressure exerted on the sensor resulting from the pressure of water above its position and the atmospheric air pressure acting on the sea surface. Whether it is not possible to use a vented reference to equalise the offset due to atmospheric pressure, the true water level is obtained from the APG by measuring and subtracting the atmospheric pressure at the sea surface from the APG measurement.</p>

<p><b>Abstract:</b> The dataset contains seafloor pressure data acquired by the seismic hydrophone installed on NEMO-SN1 observatory in the frequency band 50mHz - 1kHz. Pressure is sampled at 2kHz rate by two A/D converter (12 bit) which supply two data channel (with low, 30dB and high, 60 dB gain). Pressure data are stored in counts units; 1 count corresponds to 0.546 Pa and 0.0172 Pa for low and high gain channel respectively. Absolute time reference is available thanks to GPS data embedded in each packet of data and distributed from land station to seafloor.</p>
<p><b>Purpose:</b> The wide frequency range allows to study acoustic ambient noise in the deep water, detect sperm whale and cetaceans and detect seismic signals. It was designed to be able to detect also low frequency hydroacustic signal generated by a tsunami in case this was generated by large seismic event on the seafloor.</p>

<p><b>Period:</b> October 12, 2019 - on going</p>
<p><b>Abstract:</b> This sensor provides the three components of the magnetic induction vector in the directions N-S, E-W and Z (vertical). It is a fluxgate prototype developed at INGV laboratories equipped with an inertial platform for levelling control. It provides continuous seafloor magnetic data which are important for two main reasons: a) they extend the magnetic observations from land to the seafloor, improving the spatial distribution in the Italian territory; b) these data are important for the study of short and long magnetic field time variations. The variational data allow us to estimate the resistivity structure underneath the area of observations and possibly to detect some magnetic variations related to some geo-hazards, such as earthquakes and tsunamis.</p>
<p><b>Purpose:</b> The main aim is the continuous and almost real-time measurement of the three components of the Earth’s magnetic field in a very peculiar environment which in fact has a favorable impact on the quality of the measurements: first, the temperature is more stable at the sea bottom, especially in deep sea sites, so the instrumental drift due to temperature variations is absent or negligible. Second, the water column acts as a natural "shield" to the highest frequencies of the iono- and magnetosphere inducing fields.</p>

<p><b>Instrument:</b> Guralp CMG-1T 3 component broadband seismometer (360 s-50 Hz)</p>
<p><b>Period:</b> October 12, 2019 - on going</p>
<p><b>Abstract:</b> This digital database comprises seismological data recorded during the SMO project by a 3 component broadband seismometer. The sensor was installed on the the NEMO-SN1 (Neutrino Mediterranean Observatory - Submarine Network 1) seafloor observatory, offshore of the Eastern coast of Sicily (Southern Italy) at a depth of 2036 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 is connected to a 24 bit digitizer on the observatory. The GPS signal is transmitted underwater to the digitizer, so that the data packages are time-stamped locally.</p>
<p><b>Purpose:</b> This project is a continuation of GNDT 1, GNDT 2 and SMO 1 where the main objective was to establish a multiparameter seafloor observatory off-shore eastern Sicily. One of the main aspects of SN1 2019 remains long-term geophysical monitoring and 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 in Italy took place (some of them generated tsunamis). For this reason a tsunami detection systems is implemented on-board the observatory and the seismometer is an important component.</p>

<p><b>Instrument:</b> Franatech METS Methane Sensor </p>
<p><b>Period:</b> September 28, 2013 - April 22, 2014</p>
<p><b>Abstract:</b> The Methane sensor provides two output analogue channels (Vmet, Vt) which are sampled at 1Hz by a dedicated Analog To Digital Converter of the SN4 station. From (Vmet, Vt) through a calibration formula, the dissolved methane concentration in sea water can be computed.
The sensor has been used with the pump.</p>
<p><b>Purpose:</b> The purpose of the methane sensor installation on the SN4 observatory is to monitor the variation of methane gas dissolved in sea water. The installation site is rich in gas seepage from seafloor, thus the variation in methane dissolved concentration can provide a mean to monitor gas emission from seabed. This sensor enable us to study methane gas emission dynamic and its correlation with other physical, oceanographical and seismic parameters in the site.</p>

<p><b>Period:</b> June 10, 2012 - June 12, 2013</p>
<p><b>Abstract:</b> The 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.</p>

<p><b>Instrument:</b> SMID seismic digital hydrophone prototype DT-405D(V)1</p>
<p><b>Period:</b> June 10, 2012 - June 12, 2013</p>
<p><b>Abstract:</b> The dataset contains seafloor pressure data acquired by the seismic hydrophone installed on NEMO-SN1 observatory in the frequency band 50mHz - 1kHz. Pressure is sampled at 2kHz rate by two A/D converter (12 bit) which supply two data channel (with low, 30dB and high, 60 dB gain). Pressure data are stored in counts units; 1 count corresponds to 0.546 Pa and 0.0172 Pa for low and high gain channel respectively. Absolute time reference is available thanks to GPS data embedded in each packet of data and distributed from land station to seafloor.</p>
<p><b>Purpose:</b> The wide frequency range allows to study acoustic ambient noise in the deep water, detect sperm whale and cetaceans and detect seismic signals. It was designed to be able to detect also low frequency hydroacustic signal generated by a tsunami in case this was generated by large seismic event on the seafloor.</p>
<p><b>Quality of data:</b> The set contains 292.5 Gbyte of data stored in 52560 files of ten minutes each and covers 8717.82 hours of acquisition (292.5 days) which was continuous during the mission, excluding some periods when acquisition was stopped for observatory maintenance and calibrations.</p>

<p><b>Area:</b> East Sicily</p>
<p><b>Instrument:</b> Fluxgate Prototype #1</p>
<p><b>Period:</b> June 10, 2012 - June 12, 2013</p>
<p><b>Abstract:</b> This sensor provides the three components of the magnetic induction vector in the directions N-S, E-W and Z (vertical). It is a fluxgate prototype developed at INGV laboratories equipped with an inertial platform for levelling control. It provides continuous seafloor magnetic data which are important for two main reasons: a) they extend the magnetic observations from land to the seafloor, improving the spatial distribution in the Italian territory; b) these data are important for the study of short and long magnetic field time variations. The variational data allow us to estimate the resistivity structure underneath the area of observations and possibly to detect some magnetic variations related to some geo-hazards, such as earthquakes and tsunamis.</p>
<p><b>Purpose:</b> The main aim is the continuous and almost real-time measurement of the three components of the Earth’s magnetic field in a very peculiar environment which in fact has a favorable impact on the quality of the measurements: first, the temperature is more stable at the sea bottom, especially in deep sea sites, so the instrumental drift due to temperature variations is absent or negligible. Second, the water column acts as a natural "shield" to the highest frequencies of the iono- and magnetosphere inducing fields.</p>
<p><b>Quality of data:</b> The data series is almost complete for this sensor: ~96% of expected bytes has been recorded (see problems below). Althougth built with a 0.5 Hz (1 sample / 2 seconds) sampling rate, this sensor began measuring with a sampling rate of 1 sample / 3-5 seconds until September 22, 2012 (21:51:10) when its sampling rate swiched to its proper samplig rate (0.5 Hz) without an apparent reason. Anyway, ~4% of data are missing because the sensor delays erratically its measurements for 4-5 seconds for unknown reasons.
Since timestamp is associated to data after on-shore acquisition with a resolution of milliseconds, it may seem that there exists a mismatch in sampling rate when rounding to seconds, but it is only apparent (compare to Julian date).
A mismatch between the data timestamp (date/hour) and that coming from the sensor (in Julian format) exists since this latter cannot be changed nor adjusted.
Erratically, during on-shore acquisition some data strings are corrupted and this results in gaps.
Recurrent (hourly) spikes are due to the proximity of the SMO Marine Magnetics Sentinel scalar magnetometer (with 1 hour sampling).

<p><b>Area:</b> East Sicily</p>
<p><b>Instrument:</b> Guralp CMG-1T 3 component broadband seismometer (360 s-50 Hz)</p>
<p><b>Period:</b> June 10, 2012 - June 12, 2013</p>
<p><b>Abstract:</b> This digital database comprises seismological data recorded during the SMO project by a 3 component broadband seismometer. The sensor was installed on the the NEMO-SN1 (Neutrino Mediterranean Observatory - Submarine Network 1) seafloor observatory, offshore of the Eastern coast of Sicily (Southern Italy) at a depth of 2036 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 is connected to a 24 bit digitizer on the observatory. The GPS signal is transmitted underwater to the digitizer, so that the data packages are time-stamped locally.</p>
<p><b>Purpose:</b> This project is a continuation of GNDT 1 and GNDT 2 where the main objective was to establish a multiparameter seafloor observatory off-shore eastern Sicily. One of the main aspects of SMO remains long-term geophysical monitoring and 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 in Italy took place (some of them generated tsunamis). For this reason a tsunami detection systems is implemented on-board the observatory and the seismometer is an important component.</p>
<p><b>Quality of data:</b> The Z (vertical) and N components have recorded data of good quality for the duration of the deployment. The E component recorded only electronic noise from the beginning of the experiment till the 24th of August (~9 UTC) due to the fact that the mass was not released. After we were able to release the mass the E component recorded good quality signal for the rest of the mission. Due to tests, during June 2012, there are periods with electronic disturbances and presence of gaps in the data. A periodic disturbance is visible on all components due to the acoustic signal emitted when the ADCP is sampling (2 profiles/hour).</p>

<p><b>Instrument:</b> Guralp CMG-40T 3 component broadband seismometer (30 s-50 Hz)</p>
<p><b>Period:</b> October 05, 2009 - March 15, 2010</p>
<p><b>Abstract:</b> This digital database comprises seismological data recorded continuously during the MARMARA-DM 1 project by a 3 component broadband seismometer. The sensor was installed on a GEOSTAR-class deep-sea multidisciplinary observatory, deployed in the Marmara Sea at a depth of 167 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.</p>
<p><b>Purpose:</b> The major scientific goal of the SN-4 experiment is to contribute to the knowledge on the relationship between gas seepage and seismic signals. To observe a large variety of seismic signals we use a broadband seismometer. The deployment site is on the sea prosecution of the active North Anatolian fault,which has been the source of many destructive earthquakes, and presents a continuous seismic activity and methane degassing.</p>

<p><b>Area:</b> Marmara Sea</p>
<p><b>Instrument:</b> Franatech METS Methane Sensor </p>
<p><b>Period:</b> October 05, 2009 - March 15, 2010</p>
<p><b>Abstract:</b> The Methane sensor provides two output analogue channels (Vmet, Vt) which are sampled at 1Hz by a dedicated Analog To Digital Converter of the SN4 station. From (Vmet, Vt) through a calibration formula, the dissolved methane concentration in sea water can be computed.</p>
<p><b>Purpose:</b> The purpose of the methane sensor installation on the SN4 observatory is to monitor the variation of methane gas dissolved in sea water. The installation site is rich in gas seepage from seafloor, thus the variation in methane dissolved concentration can provide a mean to monitor gas emission from seabed. This sensor enable us to study methane gas emission dynamic and its correlation with other physical, oceanographical and seismic parameters in the site.</p>
<p><b>Quality of data:</b> The data set is complete. The methane concentration computed from Vmet and Vt is a raw-uncorrected data; to obtain true methane concentration the raw value must be corrected taking into account oxygen concentration, following the device calibration formula. The temperature channel measures the device temperature.</p>

<p><b>Abstract:</b> The Optode sensor measures the dissolved oxygen concentration in sea water using a lifetime-based luminescence quenching principle. The dataset includes a measured device temperature channel and the oxygen saturation values [%] computed from concentration and temperature.</p>
<p><b>Purpose:</b> The sensor is used to monitor the oxygen concentration dissolved in sea water and to provide oxygen concentration values needed by the methane sensor calibration formula.</p>
<p><b>Quality of data:</b> Raw Oxygen data as recorded by the Optode sensor from 5 October 2009 until 15 March 2010. The data set is continuous with few gaps (0.048% samples lost). The concentration values are not corrected for sea salinity. True concentration values needs post processing elaboration using salinity data [see Optode manual]. The temperature channel measures the device temperature.</p>

<p><b>Period:</b> January 25, 2005 - April 30, 2008</p>
<p><b>Abstract:</b> This 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.</p>
<p><b>Purpose:</b> 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.</p>

<p><b>Period:</b> June 14, 2004 - April 03, 2005</p>
<p><b>Abstract:</b> The 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.</p>

<p><b>Instrument:</b> Guralp CMG-1T 3 component broadband seismometer (360 s-50 Hz)</p>
<p><b>Period:</b> October 09, 2002 - May 12, 2003</p>
<p><b>Abstract:</b> This digital database comprises seismological data recorded during the GNDT 1 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 2071 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.</p>
<p><b>Purpose:</b> This project's main objective was to establish the first node, off-shore eastern Sicily, of multiparameter seafloor observatories which include a seismometer. 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.</p>
