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 (http://marnaraia.org). 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, https://www.seriestemporales-ieo.net/) and also of  the harmful algae Galician monitoring of INTECMAR (weekly sampling, http://www.intecmar.gal/).  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 seadatanet.org 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 (http://centolo.co.ieo.es:8080/thredds/catalog/rv/Navaz/catalog.html) and Geoserver (http://centolo.co.ieo.es:8080/geoserver/web/) which facilitates the user's queries, automation of routines (e. g. model validation), and the development and implementation of web services and applications. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

This data set includes recently published data used to assess the temporal evolution of pH in Atlantic and Mediterranean water masses exchanging at the Strait of Gibraltar (Long:-5.345, Lat: 36.137, Datum:WSG84) during the decade 2005-2015 and to calculate the magnitude of natural and anthropogenic components on total pH changes (Flecha et al., 2019). The database provides measurements of carbon system parameters in water samples collected at 3 stations that form the marine time series GIFT during 26 oceanographic campaigns conducted over the decade 2005–2015. Geographic coordinates of sampling stations are provided. Some physical data (i.e. temperature and salinity) are also included.

In the framework of the R/V J. Rioja (Spanish Institute of Oceanography, IEO-CSIC) routine field and monitoring operations on the Cantabrian Sea waters (southern Bay of Biscay), a continuous thermosalinometer (TSG, SeaBird 21) was installed in 2002 as an IEO contribution to the Ferrybox EU-funded project (2002-2005, EC-FP5-EESD nºEVK2-2002-00144). This research vessel has sampled the area in the framework of the IEO monitoring program RADIALES (monthly sampling, https://www.seriestemporales-ieo.net/). Data was routinely sent to the IEO datacenter and underway data are available from 15th October 2002 to 25th October 2012. During this period, the vessel performed more than 120 monthly sampling cruises with underway TSG data, recording more than 492 000 temperature and salinity lines. A recent revision, standardization and quality control/quality assessment of the dataset have been performed in the framework of SeaDataCloud project (H2020 INFRARAIA-1-2016-2017, n730960). This includes re-checking the clock, position, vessel speed, and recorded temperature and salinity values, as well as vocabularies that facilitate the accesibility of them.

The dataset contains the results of the monitoring activity in distinct years in Slovenian coastal waters related to contaminants in Sea water, sediments and biota.

The dataset comprises macronutrient (nitrate, phosphate, silicate, ammonia/ammonium) data collected on RRS James Clark Ross cruise 200 around the Scotia Sea and South Georgia in the Southern Ocean. The data were collected using CTD rosette water bottles and the ship's non-toxic seawater supply with an intake depth about 6 - 7 m between 22 February and 17 April 2009 as part of an integrated ecosystem analysis. They form part of a more extensive dataset collected over 30 years, between 1980 and 2009, by the British Antarctic Survey.
