Since 2015, 12 representative sites of the Mahoran reefs have been equipped on the sub-surface with probes measuring the temperature every 10 minutes (every 1 hour since mid-2021). The data from these probes are collected every 2 months by the Operations Department of the Parc marin de Mayotte. The aim is to better understand seasonal variations and bleaching phenomena. A computer program developed by the PNMM makes it possible to analyse these data. Regularly, new probes are purchased (NKE) and calibration tests are carried out.

The Universidad del Caribe responds to the demand for technical support for a workshop with the aim of verify environmental parameters with the use of Technology Applied to Information Registration and GPS, for the monitoring of points of interest, like define the study area, its physical description and its natural context,  operate measuring instruments and apply measurement procedures and create databases and metadata. Likewise, CTD cast were carried out to have a database with future application to mariculture, with the purpose of contributing to the economic development of communities in Quintana Roo through economic diversification and regional cultural identity and promoting fair trade and solidarity that favor the production and consumption of original products.This activities of the Node for the Promotion of the Social and Solidarity Economy (NODESS) called Selva, Mar y Comunidad Pre Registration Folio SINCA_PNSS_20_00009_INAES, made up of the Universidad del Caribe, Directorate of Economic Promotion of the H.

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.

Memorial University has over the past 15 years been involved in various ocean glider activities with deployments focused primarily on the Newfoundland Shelf and the Labrador Sea. For example, there are four deployments with glider data in the Labrador Sea. Partnerships with Fisheries and Oceans Canada and Ocean Gliders Canada have also resulted in deployments of Memorial's gliders in the Pacific. The data contain 14’663 mission kms, 620 deployment days and 25’108 individual glider profiles. L1 NETCDF files for every deployment archived on the Memorial University’s Glider Data server are made available publicly for scientific research. Deployments vary in duration and region. All files were processed with the SOCIB glider toolbox ((Troupin et al., 2015)-[https://doi.org/10.1016/j.mio.2016.01.001]), modified by Nicolai von Oppeln-Bronikowski, 2019 for MUN glider deployments. Metadata: File creator(s), contact info, institution, applicable funding, responsible researcher(s), deployment region, deployment start, deployment end, longitude min, longitude max, latitude min, latitude max, glider type, glider configuration if known, sensors, sensor serial numbers, science data QC. Glider Data: Minimum Data: Time, Depth, Position, Depth-Averaged Current, CTD. Most Deployments: Oxy_umolL, Oxy_Calphase_DEG, Oxy_sat Some Deployments: pCO2_uatm,  pCO2_Calphase_DEG, pCO2_Dphase Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

The East Sea Real-time Ocean Buoy (ESROB) is a surface mooring that has been in operation off the mid-east coast of Korea since 1999. The ESROB is 9 km off the coast (37° 32.24’N; 129° 12.92’E) in a water depth of 130 m, and provides meteorological and oceanographic (physical and biogeochemical) data every 10 min from Conductivity-Temperature-Depth (CTD) and acoustic Doppler current profiler (ADCP) instruments. The data provided here were collected between 2016 and 2020 and follow the data collected by previous publications. The data were quality controlled and assured using typical data processing methods, and have been used to address temporal variations in currents and water properties, as well as wind-and tide-induced internal waves. The uploaded data files contain variables in a NetCDF format that were obtained during each deployment.

This dataset contains seafloor pressure data acquired in the framework of EMSO-Azores observatory between August 2018 and June 2019 using a SBE53 pressure gauges deployed on two sites. West site : The sensor was deployed on an existing benchmark installed with the submersible Nautile in August 2006 during the GRAVILUCK cruise (https://doi.org/10.17600/6010110). The benchmark sits on hard substratum with light hydrothermal sedimentation, on the North-West border of the Lucky Strike lava lake, next to a hydrothermal site. East site : The sensor was deployed on an existing benchmark installed by freefall in July 2007 during the MOMARDREAM cruise (https://doi.org/10.17600/7030060). The benchmark sits in the axial valley, East of the LuckyStrike volcano in a lightly sedimented area, with apparent pillow lavas.
