  • Transborder Fix line transect are used to assess amount, composition, and spatial distribution of floating macro litter, bigger than 20 cm, along fixed trans-border transects in the Mediterranean basin. The transects, monitored all year round, cross the south east partof Ligurian Sea, Sardinian Balearic basin, Bonifacio Strait, Central Tyrrhenian Sea, Sicilian Sardinian Channels, Adriatic Sea , and Ionian Sea. The surveyed area en-compasses a large portion of the Mediterranean Sea and falls withinthree MSFD marine subregions: the Western Mediterranean Sea, theAdriatic Sea, the Ionian and Central Mediterranean Sea.

    Data showing the delineation of the terrestrial ecoregion that characterises Mediterranean-climate forests, woodlands and scrub distinguished by their biodiversity features—species endemism, the rarity of higher taxa, species richness, unusual ecological or evolutionary phenomena, and global rarity of their habitat type. The source of this database is the Terrestrial Ecoregions of the World (TEOW) dataset by Olson et al. (2001). The TEOW dataset represents a biogeographic regionalization of the Earth's terrestrial biodiversity, in biogeographic units named ecoregions. The 867 terrestrial ecoregions are classified into 14 different biomes within the eight biogeographic realms.

    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%.
