Venezuela - January 3rd, 2012

This orthorectified wide-swath ASAR image shows Ciudad Guayana (visible just above the image center), a city in Bolívar State, Venezuela. It lies south of the Orinoco, where the river is joined by the Caroní River. The city, officially founded in 1961, is actually composed of the old town of San Félix at the east and the new town of Puerto Ordaz at the west, which lie either banks of the Caroní and are connected by three bridges. The city stretches 40 kilometers along the south bank of the Orinoco.

The Orinoco is one of the longest rivers in South America at 2,140 km (1,330 mi). Its drainage basin, sometimes called the Orinoquia, covers 880,000 square kilometres (340,000 sq mi), with 76.3% of it in Venezuela and the remainder in Colombia. The Orinoco and its tributaries are the major transportation system for eastern and interior Venezuela and the llanos of Colombia. The Caroni River is the second most important river of Venezuela, the second in flow, and one of the longest, at 952 km. Visible in the lower part of the image is the large reservoir created by the Guri Dam on the Caroni River.

Vegetation Index of Orinoco River Basin and Surroundings, Venezuela and Colombia

Venezuela and Colombia - October 8th, 2010

This FAPAR image shows the vegetation index of Venezuela and parts of Colombia. Interestingly, the index is lowest (yellow in color) in the basin of the Orinoco River, which cuts diagonally across the image from southwest to northeast.

The index is highest (rusty red) to the west of the river basin, while that of the terrain to the east of the basin shows a generally good (green) index of photosynthetic activity.

This FAPAR image shows the vegetation index of Venezuela and the islands of the Lesser Antilles. Venezuela lies within the Neotropic ecozone; large portions of the country were originally covered by moist broadleaf forests. One of seventeen megadiverse countries and among the top twenty countries in terms of endemism, some 38% of the over 21,000 plant species are unique to the country.

Here, the red areas south of the Orinoco River indicate a high index of photosynthetic activity. Green areas, such as those on the majority of the islands and around the Orinoco River Delta indicate good activity. Finally, yellow to white areas, such as those on the plains of the llanos near the coast, indicate low activity.

A plume of smoke and ash can be seen crossing the image near the upper edge. This is from the eruption of the Soufrière Hills Volcano in the Lesser Antilles. Please click here for the original article regarding this eruption.

Brown sediments spill from the mouth of the Orinoco River into the Delta Amacuro and the Gulf of Paría, off the coast of Venezuela. To the south, there is a variety of landscapes,  including rainforest, the extreme northeastern extensions of the Andes that reach into the country’s northwest and continue along the northern Caribbean coast, and the llanos, extensive plains that stretch from the Colombian border in the far west to the Orinoco River delta in the east.

To the north are the islands of the Lesser Antilles, also known as the Caribbees. The Lesser Antilles are part of the Antilles, which together with the Bahamas, the Turks and Caicos Islands, and Greater Antilles form the West Indies. The islands are a long partly volcanic island arc, most of which wrap around the eastern end of the Caribbean Sea on the western boundary with the Atlantic Ocean, and some of which lie on the southern fringe of the sea just north of South America.

Along the top edge, best observed in the full image, is a cloud of gas and ash from a partial dome collapse of the Soufrière Hills volcano on Montserrat. The collapse occured on February 11th, 2010, the day before this image was taken, at 16:35 local time. The island is situated just north of the plume of ash, capped by whitish clouds, while winds carry the ash to the east and west.

The Orinoco River Empyting into the Gulf of Paría Between Venezuela and Trinidad – October 28th, 2009

Muddy brown sediments pour forth from the mouth of the Orinoco River, in Venezuela, into the Delta Amacuro and the Gulf of Paría, reaching north-northwestward towards the island of Trinidad (upper left).

The Gulf of Paria is a 7800 km2 (3000 square mile) shallow inland sea between the island of Trinidad (Republic of Trinidad and Tobago) and the east coast of Venezuela. This sheltered body of water is considered to be one of the best natural harbours on the Atlantic coast of the Americas.

The Gulf of Paria is a brackish water body – wet season salinities are below 23 ppt (parts per thousand). The extensive mangroves along the Venezuelan and Trinidad coastlines are important wildlife habitat and probably play a crucial role in regional fisheries. The Gulf itself is also an important fishery.
