Midsummer is the time for forecasts of the size of this year’s “dead zones” and algal blooms in major lakes and bays. Will the Gulf of Mexico dead zone be the size of New Jersey, or only as big as Connecticut? Will Lake Erie’s bloom blossom to a human health crisis, or just devastate the coastal economy?
We are scientists who each have spent almost 50 years figuring out what causes dead zones and what it will take to resuscitate them and reduce risks of toxic blooms of algae. Researchers can forecast these phenomena quite well and have calculated the nitrogen and phosphorus pollution cuts needed to reduce them.
