SN1 2020 - Gravimeter De Caro, Mariagrazia. (2019). Gravimeter dataset (IFSI (INAF) Prototype #2 @ 1 Hz) from INGV/NEMO-SN1 seafloor platform during EMSO-MIUR project in TestSite site (East Sicily), part of network. dataset A prototype of gravity meter built at the Istituto di Fisica dello Spazio Interplanetario (IFSI) of the National Institute of Astro-Physics (INAF) was installed on the GEOSTAR deep-sea multidisciplinary observatory in the Gulf of Cadiz (Portugal). The dataset contains relative values of gravity acceleration measured with sensitivity close to 10^-9 g/sqrt(Hz) in the range from 10^-5 to about 1 Hz. The instrument performs measurements of the Earth gravity acceleration due to low ground movements (tides) and fast ground movements (seismic wave propagation). info@moist.it Istituto Nazionale di Geofisica e Vulcanologia (INGV) en UTF-8 UTF-8 open false Multidisciplinary Oceanic Information SysTem (MOIST)
