Figure 2.27 Proportion of marine litter categories on Iberian coast beaches2.2.1.5 Wider AtlanticNo quantitative data was available for the Wider Atlantic but many items similar to those found inother Regions are found on the coastline in the Azores including plastic bags and bottles, boxes,fishing gear and nylon cables.2.2.2 Types At Sea2.2.2.1 Arctic WatersNo quantitative data was provided by Contracting Parties however, Tofta Havn, in the FaeroeIslands collected items such as plastics, polystyrene, rubber and wood from the seabed during aFishing for Litter trial.2.2.2.2 Greater North SeaIn the Dutch marine environment, raw industrial plastics in bird stomachs have shown a steadydecrease since the early 1980's with current values less than half of their initial abundance.User-plastics from discarded wastes, showed a sharp increase from the 1980's to the late 1990'sbut then started to decrease, initially at a fast rate, slower in recent years.Overall plastic mass in bird stomachs is now (2001-2005 average 29 pieces and 0.3 g per bird)similar or slightly lower than in the 1980's but in a changed composition. User plastics now largelydominate the amounts observed, whilst other categories show a significant decrease in recentyears. As demonstrated in earlier reports, shipping and fisheries are major sources of user plasticin the Southern North Sea.27
