Gyda Peninsula
Arctic peninsula with permafrost, tundra, and gas reserves.
The Gyda Peninsula, also known as the Gydansky Peninsula, juts out from Siberia’s coast into the Kara Sea. Its name comes from the Gyda River, which runs across it. The peninsula stretches about 400 kilometers in length and 360 kilometers in width, sitting between the Ob River’s Gulf of Ob and the Yenisei River’s Yenisei Gulf. Its southwestern edge is bounded by the Taz Estuary, with the Yamal Peninsula lying just across that waterway. The entire region experiences an arctic and severe climate.
The terrain is largely flat, dotted with many lakes and rivers—the Tanama River has its headwaters here. The ground is permafrost, blanketed by tundra. Several smaller peninsulas extend northward into the Kara Sea, where sizable islands like Oleniy, Shokalsky, and Vilkitsky lie offshore. Two bays indent the northern coast: the long, deep Gydan Bay and the smaller Yuratski Bay. The land between Gydan Bay and Yuratski Bay forms the Mamonta Peninsula (meaning “Mammoth Peninsula”), while the narrow strip between Gydan Bay and the Gulf of Ob is the Yavay Peninsula. Administratively, the Gyda Peninsula belongs to the Yamal-Nenets autonomous district of Russia. In English maps, it is often listed as the Gydansky or Gydanskiy Peninsula.
A notable archaeological find here is a mammoth skeleton, now displayed in a zoological museum in Saint Petersburg.
In 1996, the northernmost 8,782 square kilometers were designated a nature reserve (zapovednik), with a general ban on traffic. This Gyda Nature Reserve was managed from the regional capital, Tazovsky. On December 10, 2019, the protected area was reclassified as a national park. Starting in 2014, large holes nearly 100 feet wide began appearing on the peninsula, likely from methane gas blowouts. After a 25-year pause—the local research station had closed in 1991—scientists returned in 2016 to conduct geo-cryological studies and monitor the permafrost. In 2020, following the warmest summer recorded in the region since 1881, heavy masses of mud and permafrost slid into the Gydan Bay. These mudslides have also been linked to the recent Arctic LNG 2 project, a major natural gas extraction site built in the area.
Since 2019, the fossil gas company PAO Novatek has held permission to extract natural gas from a large portion of the peninsula. In 2020, the company announced plans to build a major port on the Gulf of Ob for gas shipments. The port is called Utrenneye, and the project is named Arctic LNG 2.

Verified Timeline
Lore & Background
The Gyda Peninsula is mostly flat, with numerous lakes and rivers. Tanama has its sources in the peninsula. Its ground consists of permafrost and is covered by tundra. This peninsula has a few arms or subpeninsulas extending northwards into the Kara Sea, where there are some large islands off its shores, including Oleniy, Shokalsky and Vilkitsky Islands. There are two bays in its northern coast, narrow and deep Gydan Bay and smaller Yuratski Bay. The peninsula formed between the Gydan Bay and neighbouring Yuratski Bay is known as the Mamonta Peninsula (Russian: Полуостров Мамонта; Poluostrov Mamonta, meaning 'Mammoth Peninsula') and the narrow peninsula in the NW formed between this bay and the neighbouring Gulf of Ob is known as the Yavay Peninsula (Russian: полуостров Явай; Poluostrov Yavay). The Gyda Peninsula is located in the Yamal-Nenets autonomous district administrative region of the Russian Federation. It appears also in the genitive as Gydansky or Gydanskiy Peninsula in many common maps in English.
Reader's Guide
A notable archeological find from the peninsula is a mammoth skeleton, now housed in a zoological museum in Saint Petersburg. In 1996 the northernmost 8,782 km² was declared a nature reserve (zapovednik), with a general ban on traffic. The reserve Gyda Nature Reserve was administered from the region capital Tazovsky. 10 December 2019 the protected area was changed into a national park. Since 2014, massive holes nearly 100 feet wide popped up on the ground of the peninsula, probably due to methane gas blowouts. In 2016, after a hiatus of 25 years (the local research station was closed in 1991), scientists were allowed back on the site to lead geo-cryological studies and monitor the permafrost. In 2020, officially following the warmest summer recorded in the region since 1881, heavy masses of mud and permafrost started to slide into the sea of the Gydan Bay. The mudslides have also been attributed to the recent launch of the Arctic LNG 2 project, an enormous natural gas extraction site built in the region. The fossil gas company PAO Novatek has since 2019 had permission for natural gas extraction from a major part of the peninsula. In 2020 the company presented plans for construction of a major port on the Gulf of Ob for gas shipment. The port is called Utrenneye and the project is named Arctic LNG 2.

Frequently Asked Questions
What is the Gyda Peninsula?
The Gyda Peninsula is a large arctic landform jutting into the Kara Sea along Russia's Siberian coast. It spans roughly 400 km in length and 360 km in width, making it one of the more substantial peninsulas in the region.
Where exactly is the Gyda Peninsula located?
It sits in the Yamal-Nenets autonomous district of the Russian Federation, wedged between the lower reaches of the Ob River and the Yenisei River. Its northern edge opens directly onto the Kara Sea.
What is the terrain and climate like on the Gyda Peninsula?
The land is dominated by continuous permafrost and open tundra vegetation, with a harsh arctic climate that keeps temperatures well below freezing for most of the year. These conditions make the area one of the most remote and environmentally extreme stretches of the Russian Arctic.
Which rivers and bays are key features of the Gyda Peninsula?
The Gyda and Tanama rivers flow across the peninsula, while its coastline is marked by two prominent inlets: Gydan Bay and Yuratski Bay. Together they shape the peninsula's distinctive lobe-like outline on the Kara Sea shore.
Why is the Gyda Peninsula drawing attention in recent years?
Large natural gas reserves beneath the permafrost have made the area a focus for extraction projects, bringing industrial activity to what was once an almost untouched wilderness. At the same time, researchers are tracking visible environmental shifts—thawing permafrost and changing tundra—linked to broader arctic warming.
