Thermosalinometer data from R/V JM Navaz (2007-2017)

In the framework of the Research Vessel JM Navaz (Spanish Institute of Oceanography, IEO) routine field and monitoring operations on the Galician coastal waters, a continuous thermosalinograph (TSG,       SeaBird 21) with a fluorometer (Turner 10) was installed in 2007 as an IEO contribution to the RAIA observatory in Galicia-North Portugal ( This research vessel has sampled the Galician Rias Baixas (Vigo, Pontevedra, Arousa and Muros) and the adjacent shelf in the framework of  the IEO monitoring program RADIALES (monthly sampling, and also of  the harmful algae Galician monitoring of INTECMAR (weekly sampling, 

Data was routinely sent to the IEO datacenter and underway data are available from 12th December 2007 to 10th January 2017. During this period, the vessel performed more than 930 sampling cruises with underway TSG data, working around 6 900 hours and sailing close to 100 000 km. It has registered more than 800 000 temperature and salinity data and more than 450 000 fluorescence records.

A recent revision, standardization and quality control/quality assessment of the dataset have been performed in the framework of SeaDataCloud (H2020 INFRARAIA-1-2016-2017, n730960) with additional support from MyCOAST (Interreg Atlantic Area EAPA 285/2016) and MarRISK (Interreg POCTEP Galicia-N Portugal, 0262_MARRISK_1_E) projects. This includes re-checking the clock, position, vessel speed, and recorded temperature, salinity and fluorometry values, as well as vocabularies that facilitate reuse of them. The whole dataset is provided with updated quality flags (QF) that improve their reusability. Weekly datafiles and the QF follow the standards, as in formats as in vocabularies, in the pursuit of the FAIR (findable, accessible, interoperable, and reusable) data principles for sharing. At the moment, these data are freely distributed using OGC standard services (WMS, WFS, etc.) through institutional Thredds ( and Geoserver ( which facilitates the user's queries, automation of routines (e. g. model validation), and the development and implementation of web services and applications.
