Lençóis Maranhenses National Park and Sediments Along Coast of Northeastern Brazil

2.7S 42.8W

Brazil – October 8th, 2012

Sediments frame the coastline of northeastern Brazil, particularly along the states of Maranhão, Piauí, Ceará and Rio Grande do Norte (left to right).

Visible in the state of Maranhão, in the upper left quadrant, is the Lençóis Maranhenses National Park (Parque Nacional dos Lençóis Maranhenses), appearing as a large white area by the coast, just east of the Baía de São José. It is an area of low, flat, occasionally flooded land, overlaid with large, discrete sand dunes. It encompasses roughly 1500 square kilometers, and despite abundant rain, supports almost no vegetation.

This FAPAR image shows the vegetation index of part of the Northeast Region of Brazil, including the states of Ceará (left), Rio Grande do Norte (right) and Paraíba (lower right).

Photosynthetic activity is highest (rusty red) to the west, in Ceará, and lowest (yellow) to the east, in Rio Grande do Norte and Paraíba. This area of low activity is bordered by strips of good activity (green) to its east and west.

Sediments Framing Northern and Eastern Coastlines of Brazil’s Northeast Region

Brazil - July 14th, 2011

This image shows part of the Northeast Region (Região Nordeste, in Portuguese) of Brazil, which is composed of the following states: Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe and Bahia, and it represents 18.26% of the Brazilian territory.

Geographically, the Northeast consists chiefly of an eroded continental craton with many low hills and small ranges. The highest peaks are around 1,850 metres (6,070 ft) in Bahia, while further north there are no peaks above 1,123 metres (3,684 ft).

On its northern and western side, the plateaus fall steadily to the coast and into the basin of the Tocantins River in Maranhão, but on the eastern side it falls off quite sharply to the coast except in the valley of the São Francisco river. The steep slopes and long cliffs of the eastern coastline are known as “The Great Escarpment”. Here, sediments frame the northern and eastern coastlines.

The escarpment serves an extremely important climatic function. Because for most of the year the Nordeste is out of reach of the Intertropical Convergence Zone, the easterly trade winds blow across the region, giving abundant rainfall to the coast but producing clear, dry conditions inland where the escarpment blocks moisture flow. This gives rise to four distinct regions, the zona da mata on the coast, the agreste on the escarpment, sertão beyond and the Mid north.

Brazil - June 26th, 2010

The northern coast of Brazil is lined by greenish sediments. Visible near the center of the shoreline is the city of Fortaleza, the state capital of Ceará and the 5th largest city in Brazil.

The city has an area of 313 square kilometres (121 sq mi). To the north of the city lies the Atlantic Ocean; to the south are the cities of Pacatuba, Eusébio, Maracanaú and Itaitinga; to the east is the county of Aquiraz and the Atlantic Ocean; and to the west is the city of Caucaia. Also visible to the south is a large reservoir with dark blue waters, created by the Orós Dam.

The city of Fortaleza, the capital of Brazil’s Ceará state, appears as an orange-tan area towards the center of the coastline. Located in Northeastern Brazil, Fortaleza has an area of 313 square kilometres (121 sq mi) and a population of over 3.4 million in its metropolitan region.

To the north of the city lies the Atlantic Ocean; to the south are the cities of Pacatuba, Eusébio, Maracanaú and Itaitinga; to the east is the county of Aquiraz and the Atlantic Ocean; and to the west is the city of Caucaia.

The land around Fortaleza is tropical forest with high rainfall of between 2,000 millimetres (79 in) and 1,700 millimetres (67 in) per year. The soil can be poor because high rainfall tends to leech out soluble nutrients.

South of the city, several large reservoirs can be seen, including the Orós Reservoir (surrounded by clouds on three sides, near the bottom center), the second-largest reservoir in Ceará. It was constructed in 1960 by damming the Jaguaribe River. The waters of the reservoir are used for irrigation upstream.
