'Blooming Gibraltar' image from the #NASA_App
From space, the Strait of Gibraltar appears tiny compared to the continents it separates. At the strait’s narrowest point, Africa stands just 14 kilometers (9 miles) from Europe. But the narrow waterway is a complex environment that gives rise to striking phytoplankton blooms when conditions are right. Water conditions and circulation near the strait produced a bloom with colorful tendrils visible in this image, acquired on March 8, 2017. The image is composed from data acquired with the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP , and the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. A series of processing steps were applied to highlight color differences and bring out the bloom’s subtler features. The intricate swirls of phytoplankton trace the patterns of water flow, which in this region can become quite turbulent. F...
