Sentinel-1 over Italy

ESA image showing Sentinel-1 flying over Italy.

Sentinel-1 carries an advanced radar instrument to provide an all-weather, day-and-night supply of imagery of Earth’s surface. As a constellation of two satellites orbiting 180° apart, the mission images the entire Earth every six days.

Deepwater Horizon MERIS 1 month later

the spill a month later as the oil had entered the Gulf of Mexico Loop Current. In this image the oil is found in the sunglint zone, and therefore appears brighter than the surrounding water because it reflects more of the direct sunlight. A transition zone marks where the oil-water contrast shifts from positive (brighter oil) to negative (darker oil).

Eye of an Algal Storm

Sentinel-2A captured this detailed image of an algal bloom in the middle of the Baltic Sea on 7 August 2015. The image, which has a spatial resolution of 10 m, reveals the bloom in exquisite detail as well as a ship heading into the ‘eye of this algal storm’. The ship’s wake can be seen as a straight dark line where the bloom has been disturbed by the ship’s propellers.
