NOAA-supported scientists on Tuesday reported that this year’s “dead zone” in the Gulf of Mexico is larger than originally predicted, at more than 16,000-square kilometers, or about the surface area of Lake Ontario and Lake Erie combined.NOAA forecasted in June that the hypoxic zone — an area with little to no oxygen to support marine life — would be 12,600 square kilometers, which would have been smaller than the five-year average. The actual size proved far larger.The annual hypoxic zone survey was conducted aboard the R/V Pelican research vessel from …

A new study suggests Earth’s supply of oxygen developed thanks to the planet’s gradually slowing rotation creating longer days that allowed a certain form of algae to admit more oxygen as a byproduct of its metabolic process.The study, published Monday in the scientific journal Nature Geoscience, suggests that about 2.4 billion years ago there was so little oxygen in Earth’s atmosphere, it could barely be measured, so no animal or plant life as we know it could exist.Much of the life on Earth consisted of tiny microbes, among them, a …
