Macheret Trench (Bulgarian : падина Мачерет, ‘Padina Macheret’ \pa-'di-na ma-che-'ret\) is the narrow, elongated subglacial valley reaching a maximum depth of 120 m below sea level beneath upper Perunika Glacier on Livingston Island in the South Shetland Islands, Antarctica. From its deepest section at 62°36'38.0"S by 60°15'55.0"W, situated north of Rezen Knoll, the feature extends below sea level 3.8 km in southeast direction to near Wörner Gap.

Perunika Glacier is an 8 km long and 3 km wide (average) roughly crescent-shaped glacier in eastern Livingston Island in the South Shetland Islands, Antarctica situated east of Pimpirev Glacier, south of Saedinenie Snowfield, southwest of Kaliakra Glacier, west of Huron Glacier, and north of Balkan Snowfield and the head of Huntress Glacier.
Livingston Island is an Antarctic island, part of the South Shetlands Archipelago in the Southern Ocean. It was the first land discovered south of 60° south latitude in 1819, a historic event that marked the end of a centuries-long pursuit of the mythical Terra Australis Incognita and the beginning of the exploration and utilization of real Antarctica. The name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s.
The feature is named after the Russian glaciologist Yuriy Macheret, leader of the Russian-Spanish-Uzbekistan ice cap radio sounding project that discovered the trench in 2006.
Russians are a nation and an East Slavic ethnic group native to European Russia in Eastern Europe. Outside Russia, notable minorities exist in other former Soviet states such as Belarus, Kazakhstan, Moldova, Ukraine and the Baltic states. A large Russian diaspora also exists all over the world, with notable numbers in the United States, Germany, Brazil, and Canada.
Glaciology is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice.

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
Spain, officially the Kingdom of Spain, is a country mostly located in Europe. Its continental European territory is situated on the Iberian Peninsula. Its territory also includes two archipelagoes: the Canary Islands off the coast of Africa, and the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Melilla, and Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country (Morocco). Several small islands in the Alboran Sea are also part of Spanish territory. The country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean.
Uzbekistan, officially also the Republic of Uzbekistan, is a landlocked country in Central Asia. The sovereign state is a secular, unitary constitutional republic, comprising 12 provinces, one autonomous republic, and a capital city. Uzbekistan is bordered by five landlocked countries: Kazakhstan to the north; Kyrgyzstan to the northeast; Tajikistan to the southeast; Afghanistan to the south; and Turkmenistan to the southwest. Along with Liechtenstein, it is one of the world's only two doubly landlocked countries.
