Image Caption: Lake Maracaibo Duck Weed:
Venezuela's Lake Maracaibo presents a complicated surface to interpret. The area is the largest oil producing region in the western hemisphere. Oil platforms and other infrastructure supporting the oil industry can be seen in the lake and along the coast. Oil slicks (very bright streaks) are common. Heavy ship traffic produces linear ship wakes. The vivid green streaks and swirls are patches of duck weed growth that has thrived on the lake this summer. The duck weed problem is so extensive that the Venezuelan government launched a massive campaign to remove it.
This image was taken by astronauts aboard the International Space Station on August 23, 2004. Sunglint--sun light reflecting off the relatively smooth water surface--produces patterns that highlights water surface features and movements. Sunglint reflects brightly off oil slicks, ship wakes and water roughened variably by wind in this image. Rough surfaces like floating vegetation (duck weed) stand out against the smooth water.
An earlier view of the duckweed swirls in Lake Maracaibo was taken by the Moderate Resolution Imaging Spectroradiometer (MODIS).
