Bering strait

  • The Bering Strait connects Asia and America, separating Siberia from Alaska.
  • It is considered a migratory bridge that could have allowed the colonization of America.
  • Marine biodiversity includes more than 160 species of algae and 420 species of fish.
  • The strait faces problems of pollution and overfishing, impacting its ecosystem.

Bering strait

The Bering Strait is a portion of the sea that stretches between the easternmost part of Asia and the northwesternmost part of North America. On the Asian side, it encompasses countries like Siberia and Russia, while on the northwestern side of North America, it includes Alaska. This strait has served as a channel connecting the Bering Sea to the north and the Chukchi Sea to the south. It holds great strategic importance and has some interesting facts worth knowing.

Therefore, we are going to dedicate this article to tell you everything you need to know about the Bering Strait and its characteristics.

Key features

The Bering Strait is 82 kilometers wide and is composed primarily of cold water. Being located near the northern hemisphere's northern latitude, it experiences relatively low temperatures year-round. It has an average depth of 30-50 meters. It was named after the Danish explorer Vitus Bering.

Within this strait lie two islands known as the Diomede Islands. They are divided into Little Diomede and Big Diomede. The former is located in North American territory, while the latter is in Russian territory. Both islands lie on the International Date Line, which divides the strait in two. Throughout history, various plans have been proposed for the construction of a bridge to connect the two ends of the Bering Strait. This would have allowed for trade between Asia and America. This project was abandoned due to the success of the transatlantic telegraph cable.

It was later revived in 2011 as a commercial shipping route between the United States, Russia, and China, which could include a 200-km-long undersea tunnel. Currently, this entire area of ​​the Bering Strait is a closed military zone. Visits are only possible with the appropriate permits from the Russian government. Strict controls are in place throughout the region. The only nearby Russian settlements are the cities of Anadyr and Provideniya.

Bering Strait theory

theories about human expansion

There are several theories and interesting facts about the Bering Strait. Many experts claim that this strait could have facilitated the colonization of the Americas. Numerous theories exist about human migration from Asia to the Americas in ancient times. Most of these theories point to the Bering Strait as a possible explanation. The lower sea levels caused by an ice age or glaciation would have exposed a vast land bridge connecting the two continents. This could have allowed some human ancestors to migrate across.

This is one of the theories about the expansion of humans from Asia to the Americas. This natural land bridge would be known as the Beringia land bridge. If this theory were true, this strait could have facilitated the human colonization of the entire American continent and, above all, a parallel evolution with respect to their European and Asian cousins. As global temperatures rose again, this land bridge would have disappeared, melting into the sky. The ocean level would have risen again, submerging the natural bridge between the continents . In this way, the American inhabitants were isolated, and this theory is still debated by experts in the field today.

This is how the Americans had to develop independently of the Europeans and Asians.

Biodiversity of the Bering Strait

union between continents

As we mentioned earlier, this strait is located in the Bering Sea. This sea is home to a wide variety of animal and plant species and is considered a marine ecosystem of great importance. All the Arctic areas surrounding this strait benefit from this biodiversity. This is because its waters are home to a multitude of marine mammals, mollusks, crustaceans, fish, and other animals of a microscopic size.

There are more than 160 species of floating algae that have their ecosystem in the Bering Sea. For example, we find the giant brown algae that are capable of forming lush forests in some aquatic areas. There are a total of approximately 420 species of fish that has helped the proliferation of fishing and the business with it. However, there are some impacts and threats that are affecting the Bering Sea.

The Bering Strait is heavily impacted by human activity, which also causes problems at sea. It is a particularly vulnerable area to environmental issues and the negative effects of global warming. This is the basis for the Bering Strait theory mentioned earlier. Being closer to the Arctic Ocean, it is more sensitive because it is being affected by rising sea levels resulting from the melting of the polar ice caps.

Contamination

The Bering Strait also suffers a pollution process due to the various productive activities of human beings. Fishing suffers from exploitation and serious problems have been caused to many species. For example, the westernmost area has a serious state of overfishing and illegal fishing.

Some parts of this sea have been contaminated with large quantities of organic waste and microscopic toxic substances. The problem with these substances is that they are more difficult to remove. Polychlorinated biphenyls (PCBs), which are persistent organic pollutants, have been found in the bodies of many marine animals, along with traces of mercury, lead, selenium, and cadmium. We also see impacts from maritime traffic that disrupt marine life and a high risk of oil spills.

As you can see, this strait holds many curiosities and theories that could affirm that the human being could expand thanks to its presence. I hope that with this information you can learn more about the Bering Strait and its characteristics.
