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.

Purpose, debit and coordinates of points from where seawater is extracted

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.

This dataset assembles historical information existing in public and private documentary archives. Taken together, these data contribute to the building of a knowledge base of the historical presence, extent and biogenic formations of European flat oyster ecosystems prior to and during the intensification of bottom fishing activities. To identify and recover such information requires significant resources and expertise. The establishment of a Historical Ecology Working Group under the umbrella of the Native Oyster Restoration Alliance in early 2020 presented a unique opportunity to coalesce interdisciplinary expertise and resources from multiple European countries to collate and interrogate historical data sources. To date, this is the only known dataset that evidences the past distribution, extent and characteristics of this seabed ecosystem across its full biogeographic range. The described datasets present qualitative and quantitative extracts from written records published between 1524-2022, which show: (1) estimated locations of past oyster fisheries and/or reef habitat across its full biogeographical range, with associated levels of confidence; (2) recorded extent of past reef habitats, and; (3) species associated with these habitats. This comprehensive historical analysis demonstrates that oyster reefs were once a dominant three-dimensional feature along much of the European coastline and some shallow shelf seas.

This dataset includes data of plastic litter collected by citizens and students during 12 campaigns that were organised in Crete (Greece) during the period May 2022 – May 2023. The campaigns were organized within the framework of the NAUTILOS Horizon 2020 project. More specifically the number of plastic litter items per category (using the J code List of the EMODnet Chemistry Thematic Lot n°4) was recorded together with information about the location, date, surface area covered, data contributor and some environmental characteristics (sediment, weather, surroundings).

The dataset includes time-series of Posidonia oceanica production over ~20 years (1997 -2018) at sixty sites in the Greek Seas. The dataset also include environmental variables for the same sites and time -period (i.e., sea surface temperature, sea surface temperature of August, Chlorophyll a, Suspended particulate matter, Secchi depth)

This dataset gather isotopic ratios measured on 359 fish, sharks and crustaceans collected between 200 and 800 m depth, in the Mediterranean canyons during MEDITS 2012 and 2013 surveys Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

These data were collected during the period of 27/11/2020 and 18/11/2022 from the Heraklion Coastal Buoy station North of Crete. The dataset is comprised of samples collected and analysed under specific dates from this station while being part of the European project: "JERICO S3 (Joint European Research Infrastructure of Coastal Observatories: Science, Service, Sustainability)".

The Universidad del Caribe responds to the demand for technical support for the elaboration of specific bathymetric charts for a polygon of 458 Ha that is located between the Isla Contoy National Park and Cayo Alcatraz. The objective was to make a bathymetric map of the polygon and point out the main characteristics or morphological features. 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.

CTD measurements as a part of observation plan in the coastal area near Mersrags were performed within the project "AQUAFIMA – Integrating Aquaculture and Fisheries Management towards a sustainable regional development in the Baltic Sea Region". Observations were made at a potential fish spawning and nursing site in the coastal area of the Gulf of Riga in August 2013.
