Operational Navigation Chart C-8, 2nd edition

Diomede Islands Bering Sea Jul 2006

Bering Strait is a narrow sea passage that lies between the easternmost point of the Asian continent (Russia) and the westernmost point of the North American continent (Alaska, United States). It connects the Arctic Ocean with the Pacific Ocean and has been a significant location for both historical migrations and modern-day geopolitics. The strait is approximately 53 miles (85 kilometers) wide at its narrowest point, with the Diomede Islands (one belonging to Russia and the other to the United States) nearly midway across, serving as a natural midpoint marker.

History

The Bering Strait is named after Vitus Bering, a Danish explorer who sailed under the Russian flag and first documented the passage in 1728. However, the strait has been known and used for thousands of years, serving as a migration route for peoples, animals, and later, explorers and traders. It is widely believed that during the last Ice Age, the Bering Strait was a land bridge, known as Beringia, which allowed humans and animals to cross from Asia to North America.

Geography

The Bering Strait's geography is characterized by its harsh climate, with ice covering the sea for much of the year. The strait divides two continents, with Cape Dezhnev in Russia and Cape Prince of Wales in Alaska being the closest points. The waters are relatively shallow, with depths averaging between 30 to 50 meters, which has implications for marine navigation and ecosystem dynamics.

Ecology

The Bering Strait is home to a unique and biodiverse marine ecosystem, including species such as the polar bear, walrus, and various types of seals and whales. The strait serves as a crucial migration route for many marine mammals and seabirds. The productivity of the region's marine life is supported by the nutrient-rich waters, which are a result of the mixing of the cold, fresh waters from the Arctic with the warmer, saltier waters from the Pacific.

Economic and Strategic Importance

The Bering Strait has significant economic and strategic importance. It is a vital route for ships traveling the Northern Sea Route, which is becoming more accessible due to climate change and the melting of Arctic ice. This has implications for international trade, as well as for the geopolitical interests of countries bordering the Arctic, including Russia and the United States. The strait is also important for the indigenous peoples of the region, who rely on its resources for their subsistence lifestyle.

Future Prospects

The future of the Bering Strait is closely tied to the impacts of climate change, with predictions of reduced ice cover potentially increasing maritime traffic and access to natural resources. This raises concerns about the environmental protection of the region, the sustainability of its ecosystems, and the livelihoods of indigenous communities.
