Marine microbes prove potent greenhouse gas emitters
Earth’s oceans emit an estimated 30 percent of the nitrous oxide, or N2O, entering the atmosphere. Yet the source of this potent greenhouse gas has puzzled scientists for years. Bacteria — long the leading candidate — can generate nitrous oxide, but the seas don’t seem to contain enough to account for all of the nitrous oxide that the marine world has been coughing up. Now researchers offer a better candidate.

Eels point to suffocating Gulf floor
In June, scientists predicted that the Gulf of Mexico’s annual dead zone — a subsea region where the water contains too little oxygen to support life — might develop into the biggest ever. In fact, that didn’t happen. Owing to the fortuitous arrival of stormy weather, this year’s dead zone peaked at about 6,800 square miles, scientists reported on Aug. 1 — big but far from the record behemoth of 9,500 square miles that had been mentioned as distinctly possible.
