The system consists of an underwater seismometer, a surface buoy, and a mooring line that connects them. Inductive communication through the mooring line provides an inexpensive, reliable, and flexible solution. Prior to the deployment the dynamics of the system have been simulated numerically in order to find optimal materials, cables, buoys, and connections under critical marine conditions. The seismometer used is a high sensitivity triaxial broadband geophone able to measure low vibrational signals produced by the underwater seismic events. The power to operate the surface buoy is provided by solar panels. Additional batteries are needed for the underwater unit. In this paper we also present the first results and an earthquake detection of a prototype system that demonstrates the feasibility of this concept. The seismometer transmits continuous data at a rate of 1000 bps to a controller equipped with a radio link in the surface buoy. A GPS receiver on the surface buoy has been configured to perform accurate timestamps on the seismic data, which makes it possible to integrate the seismic data from these marine seismometers into the existing seismic network.<\/jats:p>","DOI":"10.3390\/s18041132","type":"journal-article","created":{"date-parts":[[2018,4,10]],"date-time":"2018-04-10T13:06:08Z","timestamp":1523365568000},"page":"1132","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Real-Time Seismic Data from the Bottom Sea"],"prefix":"10.3390","volume":"18","author":[{"given":"Xavier","family":"Roset","sequence":"first","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]},{"given":"Enric","family":"Trullols","sequence":"additional","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]},{"given":"Carola","family":"Artero-Delgado","sequence":"additional","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]},{"given":"Joana","family":"Prat","sequence":"additional","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6191-2201","authenticated-orcid":false,"given":"Joaquin","family":"Del R\u00edo","sequence":"additional","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]},{"given":"Immaculada","family":"Massana","sequence":"additional","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]},{"given":"Montserrat","family":"Carbonell","sequence":"additional","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]},{"given":"Jaime","family":"Barco de la Torre","sequence":"additional","affiliation":[{"name":"Instituto Geogr\u00e1fico Nacional C\/General Ib\u00e1\u00f1ez de \u00cdbero 3, 28003 Madrid, Spain"}]},{"given":"Daniel","family":"Toma","sequence":"additional","affiliation":[{"name":"SARTI Research Group, Universitat Polit\u00e8cnica de Catalunya (UPC), 08800 Vilanova i la Geltr\u00fa, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2018,4,8]]},"reference":[{"key":"ref_1","first-page":"607","article-title":"The monterey bay broadband ocean bottom seismic observatory","volume":"49","author":"Romanowicz","year":"2006","journal-title":"Ann.
