AndreaBozzo/ceres-open-data-index huggingface dataset:
Particle size distribution, suspended matter, water velocity (profile) Salinity, temperatuur measured with the MOMO tripod

The main part of the dataset has been collected within the MOMO project (Monitoring and modelling of cohesive sediment transport and evaluation of the effects of dredging and dumping operations on the marine ecosystem) at four locations (MOW1, Blankenberge, WZ-buoy, MOW0, Ostend and Geul van de Walvisstaart buoy). A large part of the data is from the MOW1 station, situated about 3 km offshore the harbour of Zeebrugge. Shorter time series have been collected for the Environmental Impact Assessment of the Belwind offshore windfarm at two locations (Blighbank, Gootebank) and the MOZ4 project (Westdiep location). A central objective of the MOMO project is to collect long-term time series of Suspended Particulate Matter concentration, size and transport in the coastal turbidity maximum located in the Belgian Part of the North Sea. Data from two sensors are included in this dataset. First, from a LISST-100X instrument, which contains four parameters: the optical transmission, the median distribution of the sediment particle size (micrometers), the Sauter mean diameter (micrometer) and the total SPM volume concentration (microlitres/litre). Second from in-situ observation of water turbidity derived from an Optical Backscatter Sensor (OBS) together with a CTD sensor. The following parameters are included: water pressure, salinity, water temperature, turbidity and SPM mass concentration (mg/l). The OBS is calibrated in the laboratory using standard turbidity solutions, and in the field using SPMC determined through filtration of water samples.

Greek Shark Logbook 2025

The Greek Shark Logbook 2025 is a citizen science dataset documenting shark sightings and encounters in Greek marine waters during the year 2025. The dataset compiles georeferenced records submitted by fishers, divers, researchers, and the general public, which were reviewed and validated before publication. It provides species occurrence information with basic biological and contextual details and is openly available through figshare.

The dataset aims to improve knowledge of shark distribution and seasonal presence in the Aegean and Ionian Seas and to support marine biodiversity monitoring and conservation efforts. Records include the date and approximate location of sightings, species identification where possible, and notes on the type of encounter, such as free-swimming individuals or incidental captures. Some records also include estimates of size, sex, or behaviour and supporting photographic evidence.

Greek Shark Logbook 2025 contributes occurrence-level biodiversity data that can support EMODnet objectives by filling data gaps for elasmobranch species in the Mediterranean. The dataset can be used for spatial analysis, temporal trend assessment, and as supporting evidence for conservation planning and ecosystem-based management.

REMP project - Abyssal classification geomorphic feature

The abyssal classification geomorphic feature layer represents the spatial extent of the abyssal areas of the worlds oceans based on interpretation of the SRTM30 plus v7 global bathymetry model. The layer is one of the 25 layers that make up the global seafloor geomorphic features map (Harris et.al. 2014). The abyss is the area of seafloor located at depths below the foot of the continental slope and above the depth of the hadal zone (defined as deeper than 6,000 m). The abyssal classification feature layer was created by clipping a layer representing the ocean with the shelf, slope and hadal layers. The resulting layer was then classification into areas of plains, hills and mountains based on variation in topography.
This data set has been used as one of the data inputs in the Atlantic REMP project. This project, funded by the European Union, worked together with stakeholders to produce a draft Regional Environmental Management Plan (REMP) for the Area in the North Atlantic, with a focus on the polymetallic sulphide deposits of the Mid-Atlantic Ridge which are of interest for deep-sea mining. There was close collaboration with the International Seabed Authority (ISA) and a consortium of scientific organisations. Marine data from multiple data services underpinned the environmental management plan development. A selection of the data sets is included in EMODnet Ingestion for wider distribution.
Magenetic anomalies in the southern Alborán Sea , where the INCRSIS seismic fault  zone triggered earthquakes  in 2106

Magnetic data were obtained during the INCRISIS cruise to address the recent and active near-surface tectonic deformations related to the 2016–2017 seismic sequence within the greater context of the 1993–1994 and 2004 sequences in the central Alboran Sea. This study provided insights into the propagation of recent fault zones and how they are linked to seafloor deformations in addition to their relationships with the former Al Idrisi Fault.

Oxygenated polycyclic aromatic hydrocarbons in mussels found on groynes and quaysides in Belgium. Single study

An analytical method was developed for the trace quantification of oxygenated polycyclic aromatic hydrocarbons (oxyPAHs) in mussels. Compounds included were naphthalene-1-ol, 9H-fluoren-9-one, anthracene-9,10-dione, 7H-benz[de]anthracene-7-one, naphtacene-5,12-dione and benzo[a]anthracene-7,12-dione. Pyrene-1-carboxaldehyde was applied as an internal standard. Sample extraction by pressurized liquid extraction was followed by clean up on silica, separation by high performance liquid chromatography and quantitative measurement by mass spectrometry with atmospheric pressure chemical ionisation. The method was validated by the analysis of spiked mussel samples, resulting in trueness values of 90-124% and measurement uncertainties of 6-49%, except for naphthalene-1-ol.  Quantification limits varied from 0.25 ng.g-1 to 10.7 ng.g-1.  The developed analytical oxyPAH method was applied on mussel samples from groynes and quaysides along the Belgian coastline and oxyPAH data were compared to PAH concentration data. The sum of 14 US EPA priority PAHs reached maxima at the eastern side of the Belgian coastal zone, with on average 202 ng.g-1 for quayside Zeebrugge and 38.4 ng.g-1 for groyne Knokke mussels. Anthracene-9,10-dione concentrations reached maxima of 19.1 ng.g-1 mussels at the most industrialized quayside of Zeebrugge. For other oxyPAHs, no clear relationship could be made with direct PAH emissions. Concentrations of anthracene-9,10-dione and 9H-fluoren-9-one were found to exceed corresponding parent PAH concentrations.

Spatial Ecological Analysis of Megavertebrate Populations

The Spatial Ecological Analysis of Marine Megavertebrate Populations (SEAMAP) initiative, a node of the Ocean Biodiversity Information System (OBIS), has developed a digital database of geo-referenced marine mammal, seabird and sea turtle distribution and abundance data.
The Spatial Ecological Analysis of Marine Megavertebrate Populations (SEAMAP) initiative, a node of the Ocean Biodiversity Information System (OBIS), has developed a digital database of geo-referenced marine mammal, seabird and sea turtle distribution and abundance data. 

SEAMAP seeks to augment the public understanding of the ecology of marine megavertebrates by: (1) facilitating study of potential impacts on threatened species; (2) enhancing our ability to test hypotheses about biogeographic and biodiversity models, and (3) supporting modeling efforts to predict distributional changes in response to environmental change. To enhance the research and educational applications of this database, SEAMAP provides a broad array of products (e.g., tabular information, maps and explicit survey meta-data) and services (e.g., web-based query, visualization and analysis tools). 

Additionally, because this publicly-available system is intended for a broad audience of educators, students, resource managers and researchers, SEAMAP is integrating this digital database with educational products and analytical tools. The OBIS-SEAMAP system takes advantage of recent technological advances to facilitate the development of new community-based data commons for biogeographic and conservation research. To date the database includes more one-million marine mammal, bird and turtle observation records from over 180 datasets.

The GEBCO_2022 Grid - A continuous terrain model of the global oceans and land

The GEBCO_2022 Grid is a global continuous terrain model for ocean and land with a spatial resolution of 15 arc seconds. In regions outside of the Arctic Ocean area, the grid uses as a base Version 2.4 of the SRTM15_plus data set (Tozer, B. et al, 2019). This data set is a fusion of land topography with measured and estimated seafloor topography. Included on top of this base grid are gridded bathymetric data sets developed by the four Regional Centers of The Nippon Foundation-GEBCO Seabed 2030 Project. The GEBCO_2022 Grid represents all data within the 2022 compilation. The compilation of the GEBCO_2022 Grid was carried out at the Seabed 2030 Global Center, hosted at the National Oceanography Centre, UK, with the aim of producing a seamless global terrain model. Outside of Polar regions, the Regional Centers provide their data sets as sparse grids i.e. only grid cells that contain data are populated. These data sets were included on to the base using a remove-restore blending procedure. This is a two-stage process of computing the difference between the new data and the base grid and then gridding the difference and adding the difference back to the existing base grid. The aim is to achieve a smooth transition between the new and base data sets with the minimum of perturbation of the existing base data set. The data sets supplied in the form of complete grids (primarily areas north of 60N and south of 50S) were included using feather blending techniques from GlobalMapper software. The GEBCO_2022 Grid has been developed through the Nippon Foundation-GEBCO Seabed 2030 Project. This is a collaborative project between the Nippon Foundation of Japan and the General Bathymetric Chart of the Oceans (GEBCO). It aims to bring together all available bathymetric data to produce the definitive map of the world ocean floor by 2030 and make it available to all. Funded by the Nippon Foundation, the four Seabed 2030 Regional Centers include the Southern Ocean - hosted at the Alfred Wegener Institute, Germany; South and West Pacific Ocean - hosted at the National Institute of Water and Atmospheric Research, New Zealand; Atlantic and Indian Oceans - hosted at the Lamont-Doherty Earth Observatory, Columbia University, USA; Arctic and North Pacific Oceans - hosted at Stockholm University, Sweden and the Center for Coastal and Ocean Mapping at the University of New Hampshire, USA.
