Phytoplankton Bloom off the Pacific Northwest #NASA

In the early afternoon on July 26, 2014, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this natural-color view of a massive bloom of phytoplankton off the coast of Oregon and Washington. The floating, plant-like organisms give the water a milky green color in satellite imagery. Marine phytoplankton require just the right amount of sunlight, dissolved nutrients, and moderate water temperatures—not too hot, not too cold—to make their populations explode into blooms that cover hundreds of square kilometers of the sea. In the Pacific Northwest of North America in the summer, warming land temperatures create favorable winds that blow offshore and push surface waters away from the coast. This causes cooler, nutrient-rich waters to well up from the depths and provide the right conditions for blooms. The phytoplankton can become a rich...
