Venezuela and Colombia – November 19th, 2012

The Gulf of Venezuela is a gulf of the Caribbean Sea, in the north of South America. It is located between Paraguaná Peninsula (right) of the Falcón State in Venezuela and Guajira Peninsula (left) in the Guajira Department of Colombia.  A 54 km (34 mi) strait, actually an artificial navigation channel, connects it with Maracaibo Lake to the south (partially visible through the clouds). Although some greenish sediments can be seen in the gulf, it is considerably clear in comparison with past image (click here)

Tropical Storm Ernesto

On July 27, a well-defined tropical wave emerged off the coastline of Africa.

The NHC first monitored this tropical wave in its tropical weather outlook on July 30, noting that the system had an accompanying low pressure area and was showing signs of development. The convection slowly organized due to generally favorable environmental conditions.

After the circulation became better defined, the NHC initiated advisories on Tropical Depression Five at 2100 UTC on August 1. At the time, the depression was located about 810 mi (1305 km) east of the Lesser Antilles, moving west-northwestward due to a cold-core low to its north.

In the 12 hours after its formation, the system’s convection became disorganized due to westerly wind shear, and the NHC remarked the potential for degeneration into a tropical wave. However, a Hurricane Hunters flight on August 2 observed tropical storm force winds, and accordingly the NHC upgraded the depression to Tropical Storm Ernesto at 2100 UTC. The next day, the storm moved over or very near Saint Lucia, and a station on the island reported a wind gust of 63 mph (101 km/h).

As of 5 p.m. AST (2100 UTC) August 3, Tropical Storm Ernesto is located within 20 nautical miles of 13.9°N 64.1°W, about 210 mi (335 km) west of St. Lucia; about 340 mi (545 km) south-southeast of San Juan, Puerto Rico. Maximum sustained winds are 45 knots (50 mph, 85 km/h), with stronger gusts. Minimum central pressure is 1002 mbar (hPa; 29.59 InHg), and the system is moving west at 18 kt (21 mph, 33 km/h). Tropical storm force winds extend outward up to 105 miles (165 km) from the center of Ernesto.

Venezuela - December 23rd, 2011

In the upper part of this wide-swath ASAR image, in the Caribbean Sea off the northeastern coast of Venezuela, is Margarita Island (Isla de Margarita), the largest island of the state of Nueva Esparta in Venezuela. The state also contains two other smaller islands: Coche and Cubagua. The island is formed by two peninsulas joined by an isthmus. It covers an area of 1,020 km². It splits into two sections linked by an 18-km (11-mi) spit of sand. It is 78 km long and its widest side measures roughly 20 km.

Visible on the mainland to the south, parallel to the coast, are Venezuela’s the northern mountains. They exten in a broad east-west arc from the Colombian border along the northern Caribbean coast, the wide plains in central Venezuela, and the Guiana highlands in the southeast. The northern mountains are the extreme northeastern extensions of South America’s Andes mountain range reach.

Ciudad Guayana Near Confluence of Orinoco and Caroní Rivers, Venezuela

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.

Gulf of Paria Between Venezuela and Trinidad and Tobago

Venezuela - January 3rd, 2012

This orthorectified wide-swath ASAR image shows the Gulf of Paria (Golfo de Paria in Spanish), a 7,800 km2 (3,000 sq mi) 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 connected to the Caribbean Sea to the north through the Bocas del Dragón (or Dragons’ Mouth) between the Paria Peninsula of Venezuela and the Chaguaramas Peninsula, and to the Columbus Channel to the south through the Boca del Serpiente (Serpent’s Mouth) between the Cedros Peninsula and the Orinoco Delta.

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 Trinidadian coastlines are important wildlife habitat and probably play a crucial role in regional fisheries. The Gulf itself is an important fishery. Major ports include the Port of Port of Spain and the Port of Point Lisas in Trinidad and the Port of Pedernales in Venezuela.
