Field work

The Tangra 2004/05 team covered either on ski or on foot an overall distance of some 200 km, mostly in harsh weather conditions and challenging unfamiliar terrain in eastern Livingston Island, including the first crossing of Bowles Ridge, and first visit and routes to Vidin Heights, Gleaner Heights, Melnik Ridge, Levski Ridge, Saedinenie Snowfield, Kaliakra Glacier, Struma Glacier, middle Huron Glacier, Leslie Gap, Elhovo Gap, Gurev Gap, Yankov Gap, Pirdop Gate, Lozen Saddle, and the peaks Lyaskovets, Zograf, Lozen Nunatak, Erma Knoll, Aheloy Nunatak, Ravda, Komini, Ongal, Melnik, Castra Martis Hill, Radnevo, Zemen Knoll, and Miziya, as well as the third ascent of Presian Ridge and the island's summit Mount Friesland (1700 m). In particular, the survey team traversed the main crest of Tangra Mountains between Mount Friesland and Lyaskovets Peak. [1]

Extensive geodetic and geographic information was gathered, including coordinates and elevation data, actual sea shoreline and ice-free zones configuration, as well as a detailed photographic documentation of previously unexplored and remote areas in the interior of Livingston Island and Greenwich Island.

Legacy

Based on the survey, 146 geographical features were mapped for the first time, and the coordinates of other 8 features were updated. A new 1:100000 scale topographic map of the islands of Livingston and Greenwich was published in August 2005 in 1802 hard copies, and also made available in electronic version both in the website of the Ministry of Foreign Affairs of Bulgaria, and in the Wikimedia Commons. Data from the Tangra 2004/05 expedition was extensively used also in the 2009 Bulgarian map of Livingston, Greenwich, Robert, Snow, and Smith Islands.

In connection with the work carried out by the Tangra 2004/05 Expedition, 126 new Bulgarian names for hitherto nameless geographical features on Livingston Island and Greenwich Island were approved on 11 April and on 4 November 2005.

Invited lectures on the results of the expedition were given at the Faculty of Geology and Geography at Sofia University, the Ministry of Foreign Affairs of Bulgaria, the State Commission on Information Security, the Municipality of Radnevo etc.

Field work carried out during the survey was noted in 2012 by Discovery Channel, the Natural History Museum, the Royal Collection and the British Antarctic Survey as a timeline event in Antarctic exploration. [2] [3]

Its elevation was estimated at 1,684 metres (5,525 ft) by a 1995/96 Bulgarian survey; the present figure was produced by a 2003 Australian GPS survey, and closely matched by the Bulgarian survey Tangra 2004/05.
