EcoAlert: Massive Algae Bloom in Baltic Sea

Bloom_esa_660
 

This satellite image from the European Space Agency captures a 377,000-square-kilometer (145,000-square-mile) algal bloom in the Baltic Sea that could pose a risk to marine life in the Baltic Sea. The blue-green bloom, which stretches from Finland in the north to parts of Germany and Poland in the south, is the largest scientists have seen in the Baltic in five years. They say that warm sea temperatures and a lack of wind — coupled with fertilizer from regional agriculture washing into the Baltic — caused the bloom. This rapid growth consumes oxygen in the water, threatening marine life and destabilizing ecosystems across the region. The arrival of strong winds and waves, along with cooler ocean temperatures, could break up the bloom.
