Captain Arturo Prat Base is a Chilean Antarctic research station located at Iquique Cove, Greenwich Island in the South Shetland Islands, Antarctica.

Opened February 6, 1947 by the First Chilean Antarctic Expedition, it is the oldest Chilean Antarctic station. Until March 1, 2006, it was a base of the Chilean Navy, on which date it was handed over to the regional government of Magallanes and Antártica Chilena Region. Until February 2004, it had been a permanent base. Afterwards, it had served as a summer base for ionospheric and meteorologic research. There have been plans to reopen the station for permanent occupation starting March 2008. The base is named for Captain Arturo Prat, a Chilean naval officer.

Climate

The climate is maritime polar (Köppen: ET), being on the coast of the peninsula with less severe averages than expected in Antarctica.[2][3] Extreme temperatures can reach −29 °C or −20.2 °F in July, which is still quite bearable to humans protected due to considerable moderation of the sea, and a rare heat wave caused the temperature to reach 19 °C or 66.2 °F, a relatively high value. The climate is quite humid for its location and precipitation is fairly well distributed, so that even in the driest months it receives more precipitation than almost all of the Mediterranean zone.[4]

IMO Secretary-General visits Antarctica (32080302083).jpg

IMO Secretary-General Kitack Lim experienced polar conditions at first hand during a recent visit to Antarctica (8-12 February 2017). Shipping in waters surrounding the two poles has increased in recent years. IMO’s Polar Code entered into force on 1 January 2017, bringing in additional safety and environmental provisions for ships operating in these harsh, remote and unique conditions.

Secretary-General Lim was hosted by the Chilean Navy during his journey to King George Island in Antarctica. In Punta Arenas, the southern tip of Chile, he met with stakeholders from various maritime organizations. They discussed the relevance of the Polar Code to ships operating in the polar regions and the need to promote safe and sustainable shipping.

The Polar Code aims to protect the lives of crews and passengers and minimise the impact of shipping operations on the pristine polar regions.
