Venezuela and Colombia – June 5th, 2013

Though undoubtedly shocking and disconcerting, the recent Deepwater Horizon oil spill in the Gulf of Mexico is hardly the first incident of its kind in the region. Starting in the 1920s, American and British subsidiaries of Standard Oil of New Jersey, Gulf and Royal Dutch Shell turned environmentally pristine Lake Maracaibo (below), which empties out into the Gulf of Venezuela (above) and the Caribbean, into toxic sludge.

Travel to Lake Maracaibo today and you can still see the relics of the pioneering petroleum past: hundreds of offshore oil derricks dot the horizon as far as the eye can see. During the 1920s oil was a messy business and blow-outs, fires and fantastic gushers were a common occurrence. Just as in Louisiana today, the oil industry in Lake Maracaibo put delicate lakeshore mangroves in danger as well as tropical wildlife.

The water used by local residents for domestic uses came from the lake itself, and reportedly there was little risk of getting sick from the water as it was clean, such that one could even see the head of a coin or a needle in the water. With the arrival of the oil companies however, the water became dirty (click here for more information).

Issues for Lake Maracaibo, Venezuela

Venezuela – January 17th, 2013

Visible at the bottom left of this image is Lake Maracaibo, in Venezuela, connected to the Gulf of Venezuela via the 55 km long Tablazo Strait. Some green swirls of color on the lake are due to the growth of duckweed, a problem plaguing the lake since the early 2000s. At times, over 18% of the lake has been covered by duckweed, and although efforts to remove the plant have been underway, the plant – which can double its size every 48 hours – occupies over 130 million cubic metres of the lake.

The only way to remove the weed is to pull it out of the lake physically – no chemical or biological method has been found to treat the weed. The government has been spending $2 million monthly to clean the lake, and the state-run oil company Petroleos de Venezuela S.A. has created a $750 million cleanup fund. Current efforts are barely keeping up with the growth of the plant. The removal process has proven to be particularly difficult in the center of the lake where a specially equipped ship may be needed to pull the weed off the lake.

Venezuela and Brazil – January 17th, 2013

Plumes of smoke from fires in Venezuela can be seen blowing towards the southwest, just north of the Meta River. The Meta flows east-northeastward across the Llanos Orientales plains of Colombia, later forming the border with Venezuela. By Puerto Carreño, it flows into the Orinoco. The river is 804 kilometres (500 mi) long and its drainage basin is 93,800 square kilometres (36,200 sq mi).

Venezuela and Colombia – January 6th, 2013

Sediments can be observed in the Gulf of Venezuela, a gulf of the Caribbean Sea bounded by Venezuela and Colombia. A 54 km (34 mi) strait connects it with Maracaibo Lake to the south. Here, brown sediments can be observed south of the Paraguaná Peninsula, in Venezuela (right), and streaming from the Guajira Peninsula, shared by Venezuela and Colombia, to the entrance to Maracaibo Lake.

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)
