Gydansky peninsula

The length of the peninsula is more than 400 km, the width is about 400 km. The surface is a hilly plain, composed of sea and glacial anthropogenic sediments; in the south, it includes the Tanama Upland up to 200 m high. On the peninsula there are two sub-latitudinal watersheds: the southern one, which separates the basins of the Messoyakha and Solyonaya rivers from the Anti-Payotaiha and Tanama rivers , the Nyadume hill; the northern one is the range of the Deer Horns, unnamed elevations in the vicinity of Lake Hydento. Most of the expressed orographic elements (watersheds) on the peninsula are marked (on the apex surfaces) with old (1980s) signs of the state geodetic network and do not have geographical names ^[3] . The peninsula consists of the Yavai and Mammoth peninsulas, separated by the Gydan Bay .

The land boundary of the Gydan Peninsula ^[3] (Figures denote: 1, 2, 3 - for the river Messoyakhi, respectively, lower, middle and upper; 4. - for the Shenyabyah river; 5, 6 - for the Big Heta river, respectively, upper , lower; 7 - R. Solyonnaya; 8 - R. Lower Pendamayaha)

The land boundary of the peninsula ^{[3] [4]} starts from the eastern point of the common mouth of the Taz and Maly Taz rivers at the confluence of the Manomanyi river into the main channel of the Maly Taz river and runs along the watershed separating the Messoyakha and its tributaries (the Meryoyakha, Indykyaha rivers) , Muduyakha , Nyadiakha, Nyangsyakha) from the basin of the Taz River with its tributaries (the Limbyahyaha , Kheyakha , Russkaya (Luceyakha) rivers). Further to the northeast, closer to the Yenisei River basin, the border runs along the watershed between the Salt River and its tributaries (rivers: Torcha, Kheyakha, Pendamayaha, Petrovskaya) and the Bolshoi Kheta River basin to the mouth of this river. Further along the left bank of the Yenisei to the final section of the mouth section of the Yenisei riverbed, which is fixed by a straight line drawn from the lower end (catch) of the Funtusovsky peninsula at the mouth of the Funtusov channel (point with coordinates 69 ° 36′40 ″ N, 84 ° 32 ′ 40 ″ V. d. ^{[5] [6]} ) to Cape Krestovsky on the opposite right bank of the Yenisei ^[3] .

The climate is harsh. The average January temperature is −26 - −30 ° C; July from 4 to 11.5 ° C ( 1970s data). Rainfall 200-300 mm per year. According to the conditions of the spread of cryogenic phenomena, the territory of the peninsula looks homogeneous: the depth of freezing almost everywhere exceeds 0.9 m ^[4] . Moss - lichen and shrub tundra predominate ; in the south - forest-tundra light forests. The boundary of the spread on the peninsula of north-taiga wetland forests on peat (less than 10 cm) soils and shrubs in the peaty soils is consistent with the southern borders of the Messoyakha , Saliny and Varnaeyakha river basins ^[4] .

Reindeer breeding, hunting and fishing are practiced. There are natural gas deposits on the peninsula (see Gazprom Neft #Messoyakhskiye fields ).

On the Mammoth Peninsula were found the remains of a mammoth . They now stand at the St. Petersburg Zoological Institute ^[7] .

The largest rivers of the peninsula are Yuribey , Messoyakha , Gyda , Antipayatayakha , Ngatatoyakha , Mongoche , Mongocheyakha (Sosnovaya), Bolshaya Nenereyakha , Malaya Nenereyyakha , Nadocheyakha , Levaya Ngarkasidyayaha , Periptavose , Närmhoyäyaa , Zaimoyokhaha , Levaya Ngarkasiäyaha , Periptavose , Närmhoyäyaa , a small, Nénäriäha , Nadokhoyakha , Levaya Ngarkasiayayaha

Novatek plans to build an Arktik LNG-2 plant for the production of liquefied natural gas on the peninsula. The opening and commencement of production are planned for 2022-2023 ^[8] .
