These toxic blooms can kill marine life and people who eat contaminated seafood .

这些有毒的水华能杀死海洋生物以及食用了受污染海鲜的人。

These blooms are among the largest in extent and abundance in the world .

这也是全世界面积最大、数量最多的海洋水华。

New " layers " to the satellite-based software include topographic maps of the seafloor ; locations of shipwrecks and algal blooms ; and even maps of the tiny phytoplankton that provide the bulk of the ocean 's food chain .

由卫星传送的这些新版图层包括海底的地形图，失事船只残骸以及藻花的位置，甚至还能看到作为海底食物链主体的微小浮游植物的图片。

And that 's why some scientists think that artificially fertilizing such waters with the metal could promote blooms that suck co2 out of the air .

不过，那就是为何有些科学家认为向上述海域人工施用金属肥料能助长水华，从空气中吸收co2的缘故。

In high latitudes , blooms peak in the spring and summer , when sunlight increases and the relentless mixing of the water by winter storms subsides .

在高纬度地区，因为日照的增加，冬季暴风的消退以及风暴导致的水体充分混合，水华在春夏季达到高峰。
