The eastern and western ends of the island Island are Legoupil Bay black sand and cobbled beaches. Columnar basalt outcrops are a notable feature of the western end. a insul FAUNA Confirmed breeders: Gentoo penguin (Pygoscelis papua), chinstrap penguin (Pygoscelis antarctica), Pen inity southern giant petrel (Macronectes giganteus), kelp gull (LarusNorthwest dominicanus (Nw)), and skuas (Catharacta spp.). Tr Suspected breeders: Blue-eyed shag (Phalacrocorax atricepsSubar) andea Wilson’s storm-petrel (OceanitesBone Bay Tower Is. oceanicus). Regularly haul out: Weddell seals (Leptonychotes weddellii), southern elephant seals (Mirounga leonina), and from late December, Antarctic fur seals (Arctocephalus Trgazellainity Is. ). Charcot Bay FLORA The entire centre of the island is covered by a very extensive moss carpet. Lichens Xanthoria spp., Caloplaca spp. and other crustose lichen species are present. The green alga Prasiola crispa is widespread. Mikklesen Harbor Visitor Impact KNOWN IMPACTS The erosion of multiple footpaths through vegetation between the eastern and western ends of the island. POTENTIAL IMPACTS Further damage to the vegetation and disturbance of wildlife, particularly southern giant petrels. Landing Requirements SHIPS* Ships carrying 200 or fewer passengers. One ship at a time. Maximum 2 ships per day (midnight to midnight). VISITORS No more than 100 visitors ashore at any time, exclusive of expedition guides and leaders. 1 guide per 20 visitors. No visitors ashore between 22:00hrs and 04:00hrs (local time). This is in order to establish a resting period for the wildlife. Visitor Area LANDING AREA Primary: eastern end of the island; landing either on the sand beach to the north, or on the cobbled southern beach. Secondary: northern shore of the western end of the island, with easiest access at high water. CLOSED AREAS Closed Area A: Monitoring sites for chinstrap penguins above and southeast of the eastern landing area. Closed Area B: Central part of the island covered by a very extensive moss carpet (with the exception of the designated walking route) and the northern cliffs where southern giant petrels nest. Closed Area C: Knoll on the southwestern tip of the island where southern giant petrels nest. GUIDED WALKING AREAS Only walk through Closed Area B if you can clearly recognise the designated route, which runs over the rocks along the shoreline at the eastern end, and along a narrow gravel stream bed through the vegetation. This route should only be used by closely guided groups of no more than 10 visitors. Only one group should follow the stream bed at a time, taking extreme care not to trample the edges of the vegetation. FREE ROAMING AREAS Visitors can roam freely, but under supervision, anywhere except the closed or guided walking areas. * A ship is defined as a vessel which carries more than 12 passengers.

Visitor Code of Conduct BEHAVIOUR ASHORE Walk slowly and carefully. Maintain a precautionary distance of 5 metres from wildlife and give animals the right-of-way. Increase this distance if any change in behaviour is observed. When on the same level as, or higher than, nesting southern giant petrels maintain a precautionary distance of at least 50 metres. Increase this distance if any change in the birds’ behaviour is observed. Be careful near Antarctic fur seals, they may be aggressive. Do not walk on any vegetation. CAUTIONARY NOTES Stay clear of cliffs and vertical walls and stacks as these are prone to rock falls and slides.

Results are compared with published data on requirements for growth of Antarctic macroalgae. The investigated season showed two distinct periods: Early summer lasted until end of December with comparatively cold temperatures, unstable water column and deep penetration of light; late summer started in early January and was characterized by reduced salinity due to meltwater discharge and high turbidity due to suspended sediments. Meltwater influence did not sufficiently change salinity to be responsible for the frequently noted paucity of macroalgal communities in sheltered bays. Shading by suspended sediments was equally considered to be of minor importance, as macroalgae have their optimal growth phase from September to December. During this period, light penetration and depth distribution of macro algae coincide perfectlY.

  • Western Shore of Admiralty Bay, King George Island, South Shetland Islands
    Measure 4 (2014) Annex Management Plan for Antarctic Specially Protected Area No 128 WESTERN SHORE OF ADMIRALTY BAY, KING GEORGE ISLAND, SOUTH SHETLAND ISLANDS Introduction The Western Shore of Admiralty Bay is located on King George Island, South Shetland Islands, ~125 kilometers from the northern Antarctic Peninsula. Approximate area and coordinates: 16.8 km2 (centered at 58° 27' 40" W, 62° 11' 50" S). The Area is wholly terrestrial, and the primary reasons for designation are its diverse avian and mammalian fauna and locally rich vegetation, providing a representative sample of the maritime Antarctic ecosystem. Long term scientific research has been conducted on the animals within the Area. The Area is relatively accessible to nearby research stations and tourist ships regularly visit Admiralty Bay, and the ecological and scientific values of the area need protection from potential disturbance. The Area was originally designated as Site of Special Scientific Interest (SSSI) No. 8 in Recommendation X-5 (1979, SSSI No. 8) after a proposal by Poland. The SSSI designation was extended through Recommendation XII-5 (1983), Recommendation XIII-7 (1985) and Resolution 7 (1995). A revised Management Plan was adopted through Measure 1 (2000). The site was renamed and renumbered as Antarctic Specially Protected Area (ASPA) No 128 by Decision 1 (2002). The Area lies within Antarctic Specially Managed Area (ASMA) No. 1 Admiralty Bay, King George Island, South Shetland Islands, designated under Measure 2 (2006). The biological and scientific values of the Area are vulnerable to human disturbance (e.g. oversampling, disturbance to wildlife, introduction of non-native species). Therefore, it is important that human activities in the Area are managed to minimize the risk of impacts.

McDougall, Mercy J. Borbor-Córdova, K. Paola Calle, Mónica Riofrio, Nastenka Calle, Michael G. Ikonomou and Frank A.P.C. Gobas Additional information is available at the end of the chapter http://dx.doi.org/10.5772/60205 Abstract Antarctica is one of the last frontiers of the planet to be investigated for the envi‐ ronmental transport and accumulation of persistent organic pollutants. Per‐ fluorinated contaminants (PFCs) are a group of widely used anthropogenic substances, representing a significant risk to wildlife and humans due to their high biomagnification potential and toxicity risks, especially in food webs of the northern hemisphere and Arctic. Because the assessment of PFCs in the Antarctic continent is scarce, questions linger about the long-range transport and bioaccu‐ mulation capacity of PFCs in Antarctic food webs. To better understand the global environmental fate of PFCs, sediment, lichen (Usnea aurantiaco-atra), and seabird samples (southern giant petrel, Macronectes giganteus; gentoo penguin, Pygoscelis papua) were collected around the Antarctic Peninsula in 2009.
