Guanabara Bay

Guanabara Bay is a large bay in Southeast Brazil, located in the state of Rio de Janeiro. It is the second largest bay in Brazil, covering an area of 412 square kilometres. The cities of Rio de Janeiro, Duque de Caxias, Niterói, and São Gonçalo are situated around its shores, along with four other nearby municipalities.

The bay stretches 31 kilometres in length and reaches a maximum width of 28 kilometres. Its entrance is only 1.5 kilometres wide, bordered by Pico do Papagaio (Parrot's Peak) on the eastern side and Pão de Açúcar (Sugar Loaf) on the western side.

The name "Guanabara" originates from the Tupi language, combining words that mean "bay," "similar to," and "sea." This beautiful body of water has been called "hidden water," "lagoon of the sea," and "bosom of the sea" by different people over time.

History

Guanabara Bay was first seen by Europeans on January 1, 1502, when Portuguese explorers Gaspar de Lemos and Gonçalo Coelho arrived there. Some historians believe the explorers first called the bay Ria de Janeiro, meaning "January's Ria". Over time, the name changed to Rio de Janeiro, and later the city was named after the bay. Before the Europeans arrived, the shores of the bay were home to the Tamoio and Tupiniquim tribes.

Later, in 1555, French colonists led by Admiral Nicolas Durand de Villegaignon came to the area and built a fort. They were driven away by Portuguese forces in 1563. The Portuguese then built several forts around the bay to protect it, making it very hard for ships to attack from the sea. These included Santa Cruz, São João, Lajes, and Villegaignon forts. The islands in the bay were also used by the Navy for storing supplies, hospitals, and other important structures.

Description

Guanabara Bay has over 130 islands, such as Lajes, Ilha do Governador (where Rio de Janeiro's Galeão - Antônio Carlos Jobim International Airport is located), Ilha de Paquetá, and Ilha das Cobras. Other islands include Flores, Ilha Fiscal, Ilha da Boa Viagem, Villegagnon, and Fundão.

The bay is crossed by the Rio-Niterói Bridge, which is very long and connects two sides. Many boats and ships travel here, including regular ferryboat services. Important places like the Port of Rio de Janeiro, Galeão - Antônio Carlos Jobim International Airport, and Santos Dumont Airport are located along its shores. The Federal University of Rio de Janeiro has its main campus on Fundão Island. Smaller bridges link Fundão and Governador Islands to the mainland. There is also an Environmental Protection Area called the Guapimirim APA.

Environment

Guanabara Bay used to have a rich and varied ecosystem, but it has faced serious damage in recent years, especially in its mangrove areas. The bay has been affected by urbanization, deforestation, and pollution from sewage, garbage, and oil spills. By 2014, over 70% of the sewage from 12 million people in Rio de Janeiro was flowing into the bay without treatment.

There have been three big oil spills in Guanabara Bay. The last one happened in 2000 when a leaking Petrobras underwater pipe let out a lot of oil, harming the mangrove ecosystem. Efforts are being made to help the area recover, but even more than ten years later, the mangroves have not come back to life.

One of the world's largest landfills was at Jardim Gramacho next to the bay. It closed in 2012 after operating for 34 years. The landfill provided work for 1,700 people who looked for recyclable materials.

In 2014, a Dutch athlete asked the government and companies in the Netherlands to help clean up the bay. The Dutch government responded and created a plan to support this effort.

As the city prepared to host the 2016 Summer Olympics, there were plans to improve the bay's condition. However, progress was slow, and there were worries that the improvements might not last after the Olympics.

The marine life in Guanabara Bay has been badly hurt. In the past, the bay was a place where whales were seen, but today, whales are rarely spotted. However, Bryde's whales can sometimes be seen near the bay's entrance. The bay is also home to botos, but their numbers are at risk of falling.
