Barranquilla, seen in gray at the top of the photo, covers an area of ​​about 155 sq km and is the fourth largest city in Colombia after Bogotá, Medellín and Cali. The city of Barranquilla is a major commercial center for Colombia, occupying the largest port on the Caribbean Sea. Thanks to this famous port, Barranquilla has earned the nickname ‘Colombia’s Golden Gate’ (or La Puerta de Oro de Colombia in Spanish).

The city is located near the delta of the Magdalena River, one of the largest rivers in Colombia, flowing north about 1500 km in the western part of the country before flowing into the Caribbean Sea. .

Because of the amount of sediment, as evidenced by the amount of sediment plume in her mouth and the dark color of its waters, Magdalena insisted on pulling her large stream frequently. access to the port of Barranquilla for cruise ships. This photo was taken in March 2021, before the onset of the rainy season, which begins in April.

The town of Barranquilla, with its airports visible to the south of the city, is different from the Ciénaga Grande de Santa Marta which is visible to the east which is visible in dark green. Named the Ramsar Site of International Importance, the site is important for its mangrove ecosystem, which is the largest on Colombia’s Caribbean coast. There is a habitat and winter for all kinds of birds.

Other famous landmarks include the El Guajaro Reservoir, located 50 km south of Barranquilla. The reservoir was established by the association of seven small hills in the area to provide water for the cultivation of agriculture. In addition to the release of water, water is available during the farmer’s run, even during the rainy season, leading to high levels of eutrophication in the water mixed with the flowers. of harmful microorganisms, called cyanobacteria.

These types of algae, which are common in both clean and salt water, are the reason the lake appears emerald green in today’s photography. Satellite data from the Copernicus Sentinel-2 mission can track the growth and spread of harmful algae blooms in order to alert and reduce adverse effects for tourism and fishing industries.
