The Antarctic Site Inventory project has collected baseline biological data and GEOGRAPHICAL COVERAGE site-specific descriptive information in the Antarctic Peninsula since November 1994. The Inventory divides the Antarctic Peninsula into six subareas: The goal is to build a comprehensive database to assist implementation of the 1991 Protocol On Environmental Protection to the Antarctic Treaty. Elephant Island and nearby islands (EI); This poster examines key results and findings from eleven seasons inventorying the South Orkney Islands, including Laurie, Coronation, and Signy Islands (SO); Antarctic Peninsula, and how these results and findings potentially assist environmental monitoring, conservation, and management efforts Northeast Antarctic Peninsula/northwestern Weddell Sea (NE), by Antarctic Treaty Parties. from Cape Dubouzet (63˚16’S 64˚00’W) to James Ross Island; South Shetland Islands, including Deception, Low, and Smith Islands (SH); PLAN OF WORK, LOGISTICS The Inventory initially investigated whether opportunistic, well-timed, census visits by Northwest Antarctic Peninsula (NW), trained researchers, utilizing expedition ships, are an effective means for characterizing sites from Cape Dubouzet (63˚16’S 64˚00’W) to the northern end of Lemaire Channel; and and collecting essential baseline biological data and descriptive information. Southwest Antarctic Peninsula (SW), In eleven seasons from November 1994 through February 2005, the Inventory has from the northern end of the Lemaire Channel to the demonstrated clearly the utility and cost-effectiveness of such visits. In this time frame, northern part of Marguerite Bay (68˚18’S 67˚11’W) Inventory researchers have made 639 visits to 93 Antarctic Peninsula locations. There have been repetitive visits to all sites that are most heavily visited by expedition tourists, and to all sites that exhibit the most species diversity and which are most prone to potential environmental disturbance from visitors. Southern giant petrels (Macronectes giganteus) satisfy IUCN critically endangered criteria, and their listing as a Specially Protected Species under the Antarctic Environmental Protocol In November 2003, with funding from the US National Science Foundation's Office of Polar will be considered at the 2006 Antarctic Treaty Consultative meeting. Programs, the Inventory added a second component — a five-year, long-term assessment Southern giant petrels breed at four South Shetland Islands visitor sites that are and monitoring study at Petermann Island (65°10’S, 64°10’), a heavily visited site exhibiting regularly censused by the Antarctic site Inventory — medium species diversity and a moderate sensitivity to potential disruptions from human visitors. Hannah Point, Aitcho Islands, Penguin Island, Turret Point METHODOLOGY The Inventory collects three categories of data and information: • Basic Site Information (descriptions of key physical and topographical characteristics) • Variable Site Information and Data, which includes weather and other environmental King George Is. conditions (sea ice extent, cloud cover, snow cover, temperature, wind direction Maxwell Bay TURRET POINT and speed) and biological variables (population size, breeding productivity) Marsh/Frei Stations FERRAZ STATION PENGUIN ISLAND Great Wall Station • Maps and Photodocumentation Bellingshausen Station Artigas Station King Sejong Station ARCTOWSKI STATION Nelson Is.

The declines may be indicative of some underlying environmental change affecting shag breeding success. Populations now appear to have stabilized or slightly increased, and the Inventory will continue to monitor these sites. Renaud Is.

The Adélie penguin population has declined by 50%, while Gentoo penguin — 2,232 nests the Gentoo population has shown a 40-fold increase. Still undetermined is how these trends 112 individuals relate to climatological, oceanographic, physical, chemical or other biological variables.
