In Science Friday’s previous Picture of the Week, algae blooms are more prevalent in parts of the Great Lakes, in particular Lake Erie. The article discussed the growth in numbers of blooms, which is causing problems for the natural ecosystems. The blooms block sunlight, and prevent the process of photosynthesis to occur to the plant life in the water. Less plants growing means an increase of oxygen deficiency that will effect and kill most of the native aquatic fauna. Specialists had predicted the bloom’s growth would be less rapid this year, however, the Midwest experienced a wet June, which led to an increase of dissolved phosphorus runoff going into the lakes causing rapid algae growth.
