OBSEA, ten years of coastal ocean monitoring and test site observatory

American Geophysical Union (AGU) Fall Meeting, 9-13 December 2019, San Francisco
The study of the effects of climate change on the marine environment requires the existence of sufficiently long time series of key parameters. The study of these series allows, first, to characterize the range of variability in each particular region and, secondly, to detect trends or changes that could be attributed to anthropogenic causes. For that reason, permanent observation systems are required. Obsea is a permanent seabed cabled observatory located in Costas del Garraf area (Barcelona), deployed in 2009, that has produced a 10 years dataset of physical parameters now openly available at open repositories like Pangaea [1][2]. During such period, Obsea has became part of EMSO (The European Multidisciplinary Seafloor and water column Observatory) [3] as a test site where many marine instruments, technologies and data management protocols has been tested, included the EMSO-EGIM (EMSO Generic Instrument Module) and its data management system. Obsea is also contributing to the JERICO-RI coastal community [4], where is also contributing as a coastal observatory producing data and offering the infrastructure as a test site. As example of service, during the FP7 FixO3 project, Obsea was used during 828 days from 16-02-2015 to 31-08-2017, 150 days during the test of EGIM within the EMSODev project from 1-12-2016 to 30-4-2017 and during H2020 JERICO-Next project was used 518 days from 17-10-2017 to 21-05-2019.
