Credit Lester Graham / Michigan Radio New research finds the annual dead zone in Lake Erie is getting a boost that makes it worse very quickly. That dead zone begins with nutrients, phosphorus, from agricultural runoff and other sources carried by rivers to the lake. Phosphorus fertilizes algae. The plants grow fast, then die and rot. The decomposition process robs the water of oxygen. It’s been known that when the oxygen is gone, it triggers a release of natural phosphorus from the sediment at the lake’s bottom, expanding the dead zone. That phosphorus comes from the microscopic plants and organisms decaying on the bottom of the lake. ....
Robotic laboratories on the bottom of Lake Erie have revealed that the muddy sediments there release nearly as much of the nutrient phosphorus into the surrounding waters as enters the lake s central basin each year from rivers and their tributaries. Excessive phosphorus, largely from agricultural sources, contributes to the annual summer cyanobacteria bloom that plagues Lake Erie s western basin and the central basin s annual dead zone, an oxygen-starved region that blankets several thousand square miles of lake bottom and that reduces habitat for fish and other organisms. The release of phosphorus from Lake Erie sediments during periods of low oxygen a phenomenon known as self-fertilization or internal loading has been acknowledged since the 1970s. But the new University of Michigan-led study marks the first time the process has been monitored step by step for an entire season using lake-bottom sensors. ....

Chainsaw-Wielding Man Crashes McDonald’s Store In Portland To Steal Meal Dec 17 2020, 01:03PM EST A 26-year-old man caused quite a stir in Portland yesterday, barging into a McDonald’s store and chasing away employees.
