Novel Study reveals Three Main Factors Affecting Algae Blooms in Lake Erie

For the past four years, Lake Erie has witnessed toxic algae bloom. A new study has found that over-nutrification is not the only reason that has caused algae blooms in the lake.

In 2011, the algae bloom was found in the lake and the next year, the lake experienced its largest ever dead zone. Dead zone is an area that has oxygen-depleted water and in it, fish and plants choke and die. In August 2014, a toxic algae bloom was found near Toledo, Ohio and its finding made the town to stop having its water.

Generally, toxic algae bloom is attributed to the overnutrification of the waterway and its tributaries. But the new study has found that the incidents were related to weather patterns changed by climate change.

Study’s lead author Anna Michalak, a researcher with the Carnegie Institution for Science, said that as per them there are three main factors that affect algae blooms. The three factors are the amount of water feeding into the lake, the amount of phosphorous in the water, and the current wind speed.
