Data represents the percentage of change in the intensity of sailing vessels and pleasure craft traffic in the Mediterranean Sea between years 2019 and 2022. The map is based on AIS data aggregated at 1km2 by EMODnet and expressed as total time with presence of vessels in each cell throughout the year.

The map represents the distribution of resident species of cetaceans in the Mediterranean Sea based on observations registered in EMODnet Biology Portal. Species list is based on ‘Marine mammals and sea turtles of the Mediterranean and Black Seas’, IUCN, 2012. Species list includes the following cetaceans: Common Bottlenose Dolphin, Cuvier’s Beaked Whale, Fin Whale, Long-finned Pilot Whale, Risso’s Dolphin, Short-beaked Common Dolphin, Sperm Whale, and Striped Dolphin. Species list is based on ‘Marine mammals and sea turtles of the Mediterranean and Black Seas’, IUCN, 2012.

Vulnerability is calculated based on the coverage of protected areas (PAs) and Important Areas for Biodiversity (IABs) and the cumulative tourism pressure in the Mediterranean Sea waters. PAs and IABs coverage is reclassified in scores, 1 and 2 respectively. These classes and those of cumulative pressure are combined in and reclassified into vulnerability classes according to a vulnerability matrix. IABs include: Key Biodiversity Areas (KBAs), Important Shark and Ray Areas (ISRAs), Important Marine Mammal Areas (IMMAs), Critical areas for the orca population of the Gibraltar Strait and Gulf of Cádiz, Biosphere Reserve, Cetaceans Critical Habitat, Ecologically or Biologically Significant Marine Areas (EBSAs), Particularly Sensitive Sea Areas (PSSAs), Proposed Sites of Community Importance, and World Heritage Sites.

Data representing the cumulative tourism pressure in Mediterranean Sea waters based on the intensity of maritime traffic of passengers vessels and pleasure craft. Traffic intensity was produced using AIS data aggregated at 1km2 by EMODnet and expressed as total time with presence of vessels in each cell throughout the year (hours/km2). Pressure hotspots are highlighted on the map, being classified as: 1) low; areas with cumulative presence of vessels from one hour a day to 4 months (1 quarter); 2) moderate; areas with cumulative presence of vessels between 4 and 8 months (1 to 2 quarters); 3) high, areas with cumulative presence of vessels between 8 months (2 quarters) and one year; 4) very high, areas where there is a cumulative presence of vessels exciding one year, being locations of very high traffic intensity.

Data represents the number of moorings in marina ports per kilometre of coastline for each NUTS3 or equivalent (e.g. province) region. The total number of moorings was obtained from the data compiled by ETC-UMA on the location and capacity of the marinas, assigning each port its corresponding NUTS3 code and counting the total number of moorings. This value was divided by the length of the region's coastline in km. Results show low to high intensive capacity for this activity by region.

Data showing the percentage of change in the number bed-places in Mediterranean countries between years 2019 and 2022. Data are mostly available by coastal NUTS2 regions. Data for non European Union countries are available at country level, but only coastal regions are shown on the map to highlight them. Last year reported for most non-EU countries and certain regions of France and Turkey is 2021 (2015 for Egypt).

The indicator shows the potential pressure generate by fishing activity in regions close to the coast. Med-IAMER developed an expert-based approach to estimate the spatial distribution of fishing activities and the related pressure of harmful fishing techniques on marine environments. This approach resulted in this cumulative fishing indicator, that aims at provide a spatial explicit estimation of main pressures exerted from fishing related activities, particularly trawling and dredging, taking into account the variables for which spatial data are available and that had a specific influence on marine ecosystem. Maximum distance considered is 100 km. Three variables were taken into account to produce this indicator: fishing effort, calculated by a classification of ports according to their fishing fleet tonnage, average vessel length overall and number of trawlers, using the DG MARE database on ports and fishing fleet; soft bottoms above 1.000 meters depth, and main resident endangered species of cetaceans, turtles, sharks and rays threatened by bycatch according to the IUCN Red List and reports.

The indicator of legal protection was made by summing all the legal designation categories (based on MAPAMED, the database on Mediterranean Marine Protected Areas, MedPAN, RAC/SPA, 2014) overlapping on each 1ha pixel across the whole Mediterranean Sea.

Data represents the degree of pressure based on the intensity of passengers vessels, including high speed craft, in the Mediterranean Sea (year 2022). The map is based on AIS data aggregated at 1km2 by EMODnet and expressed as total time with presence of vessels in each cell throughout the year. The indicator provides an estimate of the amount of pollution vessels produce (via fuel leaks, oil discharge, waste disposal, etc.), under the assumption that traveling ships primarily affect their immediate waters.

The map highlight the potential intensity of pressure related to marinas on marine ecosystems. The dispersal of yachting port-derived pollution was modeled as a diffusive plume up to 20 km based on the data on mooring capacity of each yachting port. The spatial proximity of yachting ports increases the overall pressures. The influence was modeled as a buffer with and exponential decay based on self calculations using mooring capacity of each yachting port. Calculations were made following the same methodology developed for ESaTDOR Project (ESPON, 2013). The extension area is based on HELCOM, 2012 and it is the theoretical maximum expansion distance for pressures generated by recreational shipping.
