MOIST also include the seafloor data acquired by the observatories by INGV from 1998. MOIST allows the access through the following selection criteria: site; time interval; instrument / sensor / parameter; project / campaign. The web interface allows the submissions of queries for data download. MOIST intends to host all the data and metadata coming from EMSO ESFRI and hopefully all collaborating projects. Current areas with data: East Sicily, East Sicily, Greek, Gulf of Cadiz, Marmara Sea, Marsili Basin, Weddell Sea. 1 0 999999 http://www.moist.it/sites/testsite/18/SN12019/adcp/74 2019-09-23T12:57:43+00:00 Nadia Lo Bue nadia.lobue@ingv.it http://www.moist.it/personnel/nadia_lo_bue/2 <p><img src='http://maps.google.com/maps/api/staticmap?center=37.547650,15.397500&amp;zoom=5&amp;size=180x180&amp;maptype=satellite&amp;sensor=false&amp;markers=color:0x61E34A|label:X|37.547650,15.397500&amp;markers=size:tiny ' width='180' height='180' align='right' border='1' hspace='10' vspace='1' /></p> <p><b>Area:</b> East Sicily</p> <p><b>Instrument:</b> Teledyne RDI WorkHorse Sentinel ADCP 600 kHz</p> <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>Purpose:</b> </p> <p><b>Quality of data:</b> </p> Istituto Nazionale di Geofisica e Vulcanologia 2019-10-12T00:00:00+00:00 37.547650 15.397500 2019-10-12T00:00:00+00:00
