巴塔哥尼亚浮游生物漩涡

Phytoplankton create rich blooms of color in the Atlantic Ocean near South America in this enhanced color image from Dec. 2, 2014. The Patagonian Shelf Break is a biologically rich patch of ocean where airborne dust from the land, iron-rich currents from the south, and upwelling currents from the depths provide a bounty of nutrients for phytoplankton. The bands of color seen here not only reveal the location of plankton, but also the dynamic eddies and currents that carry them.

2014年12月2日，在这张增强的彩色图像中，浮游植物在南美洲附近的大西洋上开出了丰富的花朵。巴塔哥尼亚大陆架断裂是一片生物丰富的海洋，来自陆地的空气尘埃、来自南方的富铁洋流和来自深处的上升流为浮游植物提供了丰富的营养。这里看到的彩色带不仅显示了浮游生物的位置，还揭示了携带浮游生物的动态漩涡和洋流。
