    The current status of national surveys on monitoring of marine debris and their impact on marine mammals and seabirds in the Convention Area has been reviewed. The CCAMLR Marine Debris Database contains data from 12 sites, most within Area 48. South Africa submitted data on beached marine debris for the first time from Marion Island (Subarea 58.7). There are 4 sites that have data for more than 3 consecutive years (ranging from 5 to 16 years), these are: Cape Shirreff, (Livingston Island, South Shetland Islands); Bird Island, (South Georgia); Signy Island, (South Orkney Islands), and King George Island, (South Shetland Islands).
    Marine debris, principally packaging items, fishing gear, and wood items, reached a peak in the period 1994-1996 at Bird Island and Signy Island, but have declined until recently. The number of debris items found has increased in the last season reported at Bird Island (2004), Signy Island (2005) and King George Island (2005). The majority of items found were packaging materials.
    The level of marine debris found in Grey-headed albatross, Black-browed albatross and Wandering albatross colonies at Bird Island in 2005 has substantially declined from previous seasons. Fishing gear such as lines and hooks and miscellaneous broken plastics continue to form the major part of the debris associated with seabird colonies.
    The number of Antarctic fur seal entanglements at Bird Island reached a peak in 1993 and has showed a general decline since, with the lowest levels on record being reported for the 2005 season. Packaging bands, synthetic string and longline fragments continue to be the main entangling materials. Seabirds were reported entangled at Bird Island for the first time. The number of seabirds contaminated with hydrocarbons remains low.
