Summary

Description
English: This image is oblique, meaning that it was taken from a sideways viewing angle from the International Space Station (ISS), rather than from a “straight down” (or nadir) view, which is typical of automated satellite sensors. The view in this image is towards the west; the ISS was located over the eastern edge of the Gulf of Mexico when the image was taken. The Mississippi River Delta and nearby Louisiana coast (image top) appear dark in the sun-glint that illuminates most of the image. Sun-glint is caused by sunlight reflecting off the water surface—much like a mirror—directly back towards the astronaut observer on the Space Station. The sun-glint improves the identification of the oil spill. Oil on the water smooths the surface texture, and the mirror-like reflection of the Sun accentuates the difference between the smooth, oil-covered water (dark to light grey) and the rougher water of the reflective ocean surface (coloured silver to white). Wind and water currents patterns have modified the oil spill’s original shape into streamers and elongated masses. Among the coastal ecosystems threatened by the spill are the Chandeleur Islands (image right centre). Other features visible in the image include a solid field of low cloud cover at the lower left corner of the image. V-shaped ship or boat wakes are visible. Wave patterns at image lower right are most likely caused by tidal effects.
