Med-IAMER project covers two main regions: the Western Mediterranean, including the Alboran Sea, as one study area and the Adriatic and Ionian Sea as the other study area. Both areas are represented by the boundaries defined by the Marine Ecoregions of the World (MEOW, Spalding et al. 2007). The ecoregion concept has been used for as these boundaries best represent the ecological differences in the Mediterranean.

POSBEMED is a Study Project of the biodiversity protection community funded by the Interreg Med Programme. The POSBEMED project deals with "Sustainable management of the systems Posidonia-beaches in the Mediterranean region". The POSBEMED project is addressing topics as GIS database on posidonia meadows, touristic activities and Pas, guidelines for sustainable beach and stranded seagrass management, strategy and action plan for Mediterranean regions and Benchmarking study on management practices for posidonia banquettes/beaches are addressed. This specific map represents the municipalities distribution where the questionnaire on the perceptions about Posidonia banquettes on Mediterranean beaches has been realized.

The map shows the distribution of ship alerts and accidents along the Mediterranean Sea, between 2008 - 2014. This point layer represent the location of ship accidents registered in the database of the Mandate of the Regional Marine Pollution Emergency Response Centre for the Mediterranean Sea (REMPEC). Database includes accidents that caused pollution by oil or other hazardous and noxious substances (HNS), or were likely to cause it.

Rivers acts as a pathway for mismanaged waste to reach the sea. Results of the monitoring in the Fiumicino canal (Tiber river-Italy), estimated that 85.4 (± 9.4) litter items get into the sea each hour, with approximately 30% of which were already fragmented. Within the Medsealitter project, a surface density at the river mouth of approximately 1,270 litter items >2.5 cm and 190 litter items >20 cm per km2 was extrapolated. The percentage of the materials found is the following: Artificial polymer materials 82%; Cloth/Textiles 1%; Metal 3%; Paper/Cardboard 8%; Processed/worked wood 1%; Rubber 5%.

The map shows the distribution of main passengers transport ports in the Mediterranean Sea. Ports are classified in groups according to its level of activity.

Heritage is our legacy from the past, what we live with today, and what we pass on to future generations. Our cultural and natural heritage are both irreplaceable sources of life and inspiration. The United Nations Educational, Scientific and Cultural Organization (UNESCO) seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world considered to be of outstanding value to humanity. This is embodied in an international treaty called the Convention concerning the Protection of the World Cultural and Natural Heritage, adopted by UNESCO in 1972. What makes the concept of World Heritage exceptional is its universal application. World Heritage sites belong to all the peoples of the world, irrespective of the territory on which they are located. The natural marine heritage is recollected into MAPAMED which is a cartographic database of key information on Mediterranean Marine Protected Areas (MPAs) potential Other Effective área-based Conservation Measure (OECMs), and more broadly on sites of interest for marine conservation. It is developed and administered jointly by UNEP/MAP-SPA/RAC and the MedPAN Association. For detailed information, please consult the MAPAMED user manual (April 2021 version).

The Marine Protected Area Protection Framework (MaPAF; Rodríguez-Rodríguez et al., 2016) was adapted to update progress on the protection of Pelagos Sanctuary marine biodiversity. Accordingly, protection was conceived as an additive process entailing two complementary factors: 1. Legal protection and 2. Managerial protection. Legal protection was assessed through two indicators: 1.1. Legal designation (this specific layer), contributing to protection coverage targets, and 1.2. Regulation stringency, contributing to strict protection targets. Managerial protection was assessed via two indicators: 2.1. Existence of a management authority for the site, and 2.2. Existence of a management plan that is fully implemented. Both indicators are expected to contribute to effective Marine Protected Areas & Other Effective Area-Based Conservation Measures (OECMs) management targets. Thus, a site can be legally protected (typically, an MPA), by management measures (e.g. an OECM), attaining different degrees of conservation to their biodiversity. Therefore, a site that has been endowed a stringent legal designation category which has an appointed managerial authority that fully implements the site’s management plan is assumed to have greater protection than a site with opposite characteristics.

Medbiolitter database summarises results of scientific studies on biodiversity and marine litter interactions in the Mediterranean Sea. To this end, information is collected from different data sources, such as institutions or projects, as well as peer-reviewed publications. The main source of data currently is LITTERBASE/AWI, including only the coverage within the Mediterranean. The database currently comprises 754 records on interactions. Interaction refers to encounters between wildlife and litter items and are classified in four categories: 1) Ingestion, which is the most frequently observed interaction, followed by 2) entanglement, which affects motility, often with fatal consequences, 3) colonization, which occurs when many species settle on floating litter, and 4) others, including different types of less frequent interaction. The database includes among others the location, the type of interaction and litter, marine realm (beach, sea surface, water column, seafloor), habitat, species, whether it occurs in a marine protected area and the type in such case, as well as references to the publication from which the data are extracted. The layer is represented in different ways in the MED Biodiversity platform: 1) Marine litter and biodiversity interactions: it shows the database by type of interaction (ingestion, entanglement, colonization and other) and marine realm (pelagic or benthic). 2) Knowledge update: changes in the number of records in each database version. It tries to represent the efforts of the PANACeA project to gather additional information on the Mediterranean Sea. 3) Marine litter knowledge from 1988 to present date: shows the years of publication of the source of the records in the database. In recent dates, especially since 2015, there has been a notable increase in the number of publications related to marine litter.
