  • 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. Ayuntamiento of Lázaro Cárdenas, Muuch Kaab Cooperative, Cooperative University of Community Innovation, Mar de las Antillas Cooperative and Tianguis del Mayab. This technical report is at the request of the Cooperativa Mar de las Antillas.

  • 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.

  • Coastal marine sediments receive intensive stress from urbanization and industrialization, which is manifested by increased contents of heavy metals and organic pollutants. Saronikos Gulf and the small embayment of Elefsis, stretch along the coast of the greater Athens and Pireaus port, the most urbanized and industrialized areas in Greece. Here we present the data of a 20-years geochemical record on grain-size, organic carbon, and major and trace elements contents of the Saronikos Gulf sediments. A total of 216 sediment samples were collected within the period of 1999 to 2018 from the four sub-sectors of the gulf, namely, the Elefsis Bay, the Inner, Outer, and Western (Megara and Epidavros basin) Saronikos Gulf. Additionally, at least one core was obtained from each sub-sector. Sediments deposited at pre-industrial periods were recognized by 14C and 210Pb datings, and served for establishing regionalized, background levels of metals. Factor analysis was conducted to reveal the inter-parametric relationships, thus their common sources, as well as transport and deposition pathways. Then, Enrichment Factors and the multi-elemental Modified Pollution Index (MPI) were calculated to assess the current environmental status of the sediments. Data of sampling sites with at least a five-year record, were assessed for temporal trends, to explore whether sustained, increasing or decreasing trends of the MPI are observed. The dataset and analyses presented here support the research article entitled Geochemistry of major and trace elements in surface sediments of the Saronikos Gulf (Greece): assessment of contamination between 1999 and 2018 by Karageorgis A.P., Botsou F., Kaberi H., and Iliakis S., https://doi.org/10.1016/j.scitotenv.2020.137046

  • The investigations of Blekinge coast started in 1978. In 1990 the program "Blekinge Kustvattenkontrollprogram" Blekinge Coastal water control programme, was formed, building on the stations sampled earlier, but with extended sampling.

  • Narrative: The mapping of the landslides have been carried out base on multibeam bathymetry recorded using Simrad EM12 and Atlas HYDROSWEEP DS multibeam echosounders, during cruises from the Spanish Fishing General Secretary (2003 and 2004) and FAUCES (2018) Project. Morphometric attributes such as slope gradients, profile curvatures, planar curvatures and roughness were obtained by ArcMap (GIS), and topographic profiles allowed us to obtain a better characterization of landslides. Also seismic records with different degrees of penetration (0.5 to 1.5 s) and resolution (from a few metres to decimetres) were analysed for landslide characterization.

  • Coral reefs are one of the most diverse ecosystems on Earth. They are currently exposed to increasing levels of anthropogenic perturbations. Several recent reviews point to the lack of good indicators for these perturbations especially to monitor their effects on fish populations or fish assemblages. The SW lagoon of New Caledonia is an ideal location to test indicator species in this context as contrasting sites are present within a small geographical range. This study analysed fish from four sites, one with heavy industrial pollution, another dominated by domestic waste, a third with historic mining activities, and the fourth as a control. The butterfly fish, Chaetodon speculum, was chosen to determine C. speculum’s potential as an indicator species due to its link to coral, its sedentary behaviour and its wide geographical distribution. The size distribution, growth rate, age distribution and whole otolith composition were analysed at each site. Age and mean growth rate were analysed from daily increments of the otoliths. The concentrations of eight elements (Li, Mg, Co, Cu, Rb, Sr, and Ba) were measured by ICP-MS in the otoliths. The sites under anthropogenic impact were distinct from the control site by fish size frequencies, age distributions, and the chemical content of their otoliths. The chemical elements Mg, Co, Cu, and Rb showed differences amongst sites. Fish belonging to the sites furthest from Noume´a could be discriminated in nearly 80% of samples or 60% of the cases when otolith weight or fish age respectively were taken into account. Ni concentrations of the otoliths were also higher in the bays where water concentrations of this element were known to be higher, but these differences were no longer significant once corrected for otolith weight.

  • This dataset contains real-time total dissolved iron concentrations ((Fe(II) + Fe(III); µmol/l) acquired from the EMSO-Azores seafloor observatory from September 2013 to February 2014 (n=332). Data are purchased by the CHEMINI Fe (CF1), a CHEmical MINIaturized analyser dedicated to in situ determination of iron concentrations (every 24 hours, with in situ calibration using a 25 µmol/l iron standard, Vuillemin et al., 2009). The instrument is deployed on TEMPO part of Seamon East environmental monitoring node. The sample inlet is located on a mussel bed at the base of the Eiffel Edifice at 1695m depth.

  • Students and researchers at the University of the Caribbean together with members of the Cooperative Sea of ??the Antilles, conducted an oceanographic campaign at the site called cayo Alcatraz, where there are two underwater springs also known as “ojos de agua”. These springs are located within the polygon of the protected area of ??the Mexican Caribbean Biosphere Reserve, to the west of Isla Contoy National Park. The purpose of the campaign was to begin studies of the environmental conditions and reconnaissance of the site. The measuring instruments used were; SonTek CastAway-CTD, and a Gopro Black 7 camera.  were made a set of 12 temperature, salinity, and conductivity profiles. Water samples were also taken for subsequent microbiological analysis.
