Region 19: Antarctica Description Figure 19.1 The distribution of Holocene volcanoes through the Antarctica region. A zone extending 200 km beyond the region’s borders shows other volcanoes whose eruptions may directly affect Antarctica. Thirty-two Holocene volcanoes are located in Antarctica. Half of these volcanoes have no confirmed eruptions recorded during the Holocene, and therefore the activity state is uncertain. A further volcano, Mount Rittmann, is not included in this count as the most recent activity here was dated in the Pleistocene, however this is geothermally active as discussed in Herbold et al. -

Neste trabalho foram analisadas as taxas de mudança da frente da geleira Polar Club e comparadas com a variabilidade interanual da temperatura do ar, na Península Potter, ilha Rei George, a fim de compreender o impacto direto das alterações do clima local na dinâmica das áreas livres de gelo. Foi utilizada uma série de dez cenas de imagens do satélite Landsat e dados de temperatura do ar superficial entre 1986 e 2011. Os resultados evidenciam uma tendência no aumento na temperatura do ar de 0,04 ºC por ano, o que resultou no incremento de 1,03 ºC nas temperaturas médias do ar para o período de 26 anos analisados. -
Volcanic Activity of Mount Melbourne, Northern Victoria Land
Volcanic activity of Mount Melbourne, Present-day geothermal activity is restricted to the summit area and consists of warm ground, fumarole ice towers and northern Victoria Land pinnacles, and cave systems in snow and firn. Warm ground temperatures were measured using mercury thermometers, and ice-structure dimensions and positions were noted. The J. R. KEYS table compares maximum ground temperatures and shows that those in January 1983 were virtually identical to those in De- Antarctic Consultant cember 1972. As in 1972, the warmest temperatures in 1983 Wellington, New Zealand were associated with patches of yellow to green moss whose presence is consistent with stable heat flow (Nathan and W. C.

Species Status Assessment Emperor Penguin (Aptenodytes Fosteri)
SPECIES STATUS ASSESSMENT EMPEROR PENGUIN (APTENODYTES FOSTERI) Emperor penguin chicks being socialized by male parents at Auster Rookery, 2008. Photo Credit: Gary Miller, Australian Antarctic Program. Version 1.0 December 2020 U.S. Fish and Wildlife Service, Ecological Services Program Branch of Delisting and Foreign Species Falls Church, Virginia Acknowledgements: EXECUTIVE SUMMARY Penguins are flightless birds that are highly adapted for the marine environment. The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species. Emperors are near the top of the Southern Ocean’s food chain and primarily consume Antarctic silverfish, Antarctic krill, and squid. They are excellent swimmers and can dive to great depths. The average life span of emperor penguin in the wild is 15 to 20 years. Emperor penguins currently breed at 61 colonies located around Antarctica, with the largest colonies in the Ross Sea and Weddell Sea. The total population size is estimated at approximately 270,000–280,000 breeding pairs or 625,000–650,000 total birds. Emperor penguin depends upon stable fast ice throughout their 8–9 month breeding season to complete the rearing of its single chick. They are the only warm-blooded Antarctic species that breeds during the austral winter and therefore uniquely adapted to its environment. Breeding colonies mainly occur on fast ice, close to the coast or closely offshore, and amongst closely packed grounded icebergs that prevent ice breaking out during the breeding season and provide shelter from the wind. Sea ice extent in the Southern Ocean has undergone considerable inter-annual variability over the last 40 years, although with much greater inter-annual variability in the five sectors than for the Southern Ocean as a whole. -
Plan Anual Antártico Del Programa Antártico Argentino 2018-2019
Programa Antártico Argentino Plan Anual Antártico 2018-2019 INTRODUCCIÓN La Argentina reivindica soberanía sobre el Sector Antártico Argentino, comprendido entre los meridianos 25° y 74° de longitud Oeste al sur del paralelo de 60° de latitud Sur, con fundamento en títulos históricos, geográficos, geológicos y jurídicos. La Argentina tiene presencia permanente e ininterrumpida en la Antártida desde el 22 de febrero de 1904, en que se estableciera la primera estación científica (Base Orcadas) en la Isla Laurie, Archipiélago de las Islas Orcadas del Sur. La Argentina, por tanto, tiene la presencia continua más antigua en la Antártida. La Argentina tiene seis bases permanentes (Carlini, Orcadas, Esperanza, Marambio, San Martín y Belgrano II) y siete bases temporarias (Brown, Primavera, Decepción, Melchior, Matienzo, Cámara y Petrel). Todas están situadas en el Sector Antártico Argentino. La Dirección Nacional del Antártico administra dos de ellas (las Bases Carlini y Brown) y el Ministerio de Defensa, a través del Comando Conjunto Antártico, administra las otras once. La Argentina es uno de los doce países que participaron en la Conferencia de Washington sobre la Antártida de 1959, y eso la llevó a ser uno de los doce signatarios originarios del Tratado Antártico. El Tratado establece que la Antártida se utilizará exclusivamente para fines pacíficos y erige a la ciencia en el centro de la actividad antártica. El artículo IV del Tratado resguarda adecuadamente las reivindicaciones de soberanía en la Antártida. Por tanto, uno de los ejes de la política exterior argentina es continuo fortalecimiento del conjunto de normas surgidas a partir del Tratado Antártico. Los lineamientos de la Política Antártica Nacional (PAN) están definidos por el Decreto 2316/90, cuyo objetivo principal es el P á g i n a 2 | 265 Programa Antártico Argentino Plan Anual Antártico 2018-2019 afianzamiento de los derechos argentinos de soberanía en la Antártida. -

Management Plan for Antarctic Specially Protected Area No. 116 NEW COLLEGE VALLEY, CAUGHLEY BEACH, CAPE BIRD, ROSS ISLAND
Management Plan For Antarctic Specially Protected Area No. 116 NEW COLLEGE VALLEY, CAUGHLEY BEACH, CAPE BIRD, ROSS ISLAND 1. Description of values to be protected In 1985, two areas at Cape Bird, Ross Island were designated as SSSI No. 10, Caughley Beach (Recommendation XIII-8 (1985)) and SPA No. 20, New College Valley (Recommendation XIII-12 (1985)), following proposals by New Zealand that these areas should be protected because they contained some of the richest stands of moss and associated microflora and fauna in the Ross Sea region of Antarctica. This is the only area on Ross Island where protection is specifically given to plant assemblages and associated ecosystems. At that time, SPA No. 20 was enclosed within SSSI No. 10, in order to provide more stringent access conditions to that part of the Area. In 2000, SSSI No. 10 was incorporated with SPA No. 20 by Measure 1 (2000), with the former area covered by SPA No. 20 becoming a Restricted Zone within the revised SPA No. 20. The boundaries of the Area were revised from the boundaries in the original recommendations, in view of improved mapping and to follow more closely the ridges enclosing the catchment of New College Valley. Caughley Beach itself was adjacent to, but never a part of, the original Area, and for this reason the entire Area was renamed as New College Valley, which was within both of the original sites. The Area was redesignated by Decision 1 (2002) as Antarctic Specially Protected Area (ASPA) No. 116 and a revised Management Plan was adopted through Measure 1 (2006). -
