Wildlife From time to time Southern elephant seals take refuge on the island to bathe in the sun and the occasional penguin visits also.

Scientific Committee On Antarctic Research
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean. SCAR's scientific work is administered through several discipline-themed ''science groups''. The organisation has observer status at, and provides independent advice to Antarctic Treaty Consultative Meetings, and also provides information to other international bodies such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC). History At the International Council of Scientific Unions (ICSU)’s Antarctic meeting held in Stockholm from 9–11 September 1957, it was agreed that a committee should be created to oversee scientific research in Antarctica. At the time there were 12 nations actively conducting Antarctic research and they were each invited to nominate one delegate to ...

An officer is a person who holds a position of authority as a member of an armed force or uniformed service. Broadly speaking, "officer" means a commissioned officer, a non-commissioned officer, or a warrant officer. However, absent contextual qualification, the term typically refers only to a force's ''commissioned officers'', the more senior members who derive their authority from a commission from the head of state. Numbers The proportion of officers varies greatly. Commissioned officers typically make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces, and the senior 13.7% of the French armed forces. In 2012, officers made up about 18% of the German armed forces, and about 17.2% of the United States armed forces. Historically, however, armed forces have generally had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers (partly ...

The advancement cycle is currently every 6 months. Only a certain number of billets (job openings for this rate) open up biannually and all third-class petty officers compete. The top scorers are chosen for advancement, but only in sufficient quantities to fill the billets available. Job description Petty Officers serve a dual role as both technical experts and as leaders. Unlike the sailors below them, there is no such thing as an "undesignated Petty Officer." E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Antarctic Expedition
The French Antarctic Expedition is any of several French expeditions in Antarctica. First expedition In 1772, Yves-Joseph de Kerguelen-Trémarec and the naturalist Jean Guillaume Bruguière sailed to the Antarctic region in search of the fabled Terra Australis. Kerguelen-Trémarec took possession of various Antarctic territories for France, including what would later be called the Kerguelen Islands. In Kerguelen-Trémarec's report to King Louis XV, he greatly overestimated the value of the Kerguelen Islands. The King sent him on a second expedition to Kerguelen in late 1773. When it became clear that these islands were desolate, useless, and not the Terra Australis, he was sent to prison. Second expedition In 1837, during an 1837–1840 expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' along a coastal area of Antarctica which he later named Adélie Land, in honor of his wife.
