Where is the Chukchi Sea Located? Key Facts & Importance

The Chukchi Sea (Click here to see map) is a marginal sea of the Arctic Ocean, nestled between Alaska (USA) to the east and Russia’s Siberia to the west. Bordered by the Beaufort Sea to the north and the Bering Strait to the south, it serves as a crucial passage connecting the Arctic and Pacific Oceans. Known for its rich biodiversity and energy reserves, the Chukchi Sea plays a vital role in climate studies and global shipping routes.

Where is the Chukchi Sea Located?

The Chukchi Sea spans:

• Latitude: Between 66°N and 73°N
• Longitude: 160°W to 180°W (International Date Line)
• Bordering Seas & Straits:
  • North: Beaufort Sea
  • South: Bering Strait (connects to the Bering Sea)
  • West: East Siberian Sea (Russia)
  • East: Alaska’s coastline

This strategic location makes it a gateway between the Arctic and Pacific, influencing global ocean currents.

Which Countries Border the Chukchi Sea?

The Chukchi Sea is shared by two nations:

• 🇷🇺 Russia (Siberia): Western shores, part of the Chukotka Autonomous Okrug.
• 🇺🇸 United States (Alaska): Eastern shores, near Arctic communities like Utqiaġvik (Barrow) and Kaktovik.

The maritime boundary between the U.S. and Russia runs through the sea, making it geopolitically significant.

Is the Chukchi Sea Part of the Arctic Ocean?

Yes, the Chukchi Sea is an Arctic Ocean extension, linked to:

• The Beaufort Sea (north)
• The Bering Sea (via the Bering Strait)

It is cold, icy waters are typical of the Arctic, with seasonal ice cover affecting navigation and wildlife.

Why is the Chukchi Sea Important?

Ecological Significance

• Home to polar bears, walruses, gray whales, and seals.
• Critical migratory route for marine species.

Economic & Strategic Value

• Contains vast oil and gas reserves (estimated 30 billion barrels of oil).
• Emerging shipping route due to melting Arctic ice (Northern Sea Route).

Climate Impact

• Melting sea ice affects global weather patterns.
• Scientists study it for climate change research.

How Deep is the Chukchi Sea?

• Average depth: 50 meters (164 feet) – relatively shallow.
• Deepest point: ~125 meters (410 feet) near the Bering Strait.
• Shelf sea characteristics: Large continental shelf supports marine life.

Thus,Chukchi Sea is a key Arctic region—ecologically rich, economically valuable, and climatically sensitive. Its location between Alaska and Russia makes it a hotspot for research, trade, and conservation efforts.
