NEAREST 1 - Gravimeter De Caro, Mariagrazia. (2007). Gravimeter dataset (IFSI (INAF) Prototype #2 @ 1 Hz) from INGV/GEOSTAR seafloor platform during NEAREST project in Iberian Margin site (Gulf of Cadiz), part of EMSO 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). The gravimeter acquired from August 27, 2007 to August 15, 2008 with a break of acquisition from 18/07/2008 to 15/08/2008 and 12 hours among 17-18/10/2007. The data are stored in a total of 326 daily binary files (~220 MB). The gravity meter has successfully recorded different teleseismic events with an high S/N ratio. info@moist.it Istituto Nazionale di Geofisica e Vulcanologia (INGV) en UTF-8 UTF-8 open false Multidisciplinary Oceanic Information SysTem (MOIST)
