Ocean Color Web Feature - Orinoco Flow

Orinoco Flow

Ocean Color Web Feature - Orinoco Flow

The Orinoco is one of the longest rivers in South America at 2,140 km, (1,330 miles). Its drainage basin, sometimes called the Orinoquia (especially in Colombia) covers 880,000 km², 76.3% in Venezuela with the rest in Colombia. The Orinoco and its tributaries are the major transportation system for eastern and interior Venezuela and the llanos of Colombia. However, since river navigation is declining in every country, many of the old waterways along the Orinoco watershed are now an obstacle to land communications rather than a useful commercial route.

Orinoco Flow

The Orinoco River regularly sends a plume of water into the Caribbean in the fall. This has already been documented in the early days of satellite ocean color measurement using CZCS data. Researchers in the area have remarked that this year's plume is unusually large and occurs at an unusual time prompting some to suggest that the Amazon River may instead be the source of this plume.

You can see the green water extending northward past Puerto Rico and the Virgin Islands in the above image. Move your pointer over the image to see computed chlorophyll concentrations in the plume. Larger chlorophyll and true color images are also available.
