Earlier this summer, the National Oceanic and Atmospheric Administration predicted a possible record-setting dead zone in the Gulf of Mexico. Now, NOAA-supported scientists have found a large dead zone, but not at as large as initially predicted. The current oxygen-free (hypoxic) zone is 5,480 square miles and was caused by nutrient runoff from agricultural and other human activities flowing from the Mississippi River watershed.
Check out this awesome post from Wired about a transformer sub built to navigate through tiny holes in Antarctic ice. The robotic submarine weighs 2,200 pounds and can transform into a pencil-shaped configuration that’s only two feet across. This engineering marvel will allow researchers to study areas in the Southern Ocean that were previously too difficult to get reach.
The water on Venus boiled away long ago. As carbon dioxide levels continue to increase here on our planet, what are the chances that climate change will cause our oceans to boil away? In this interview with the author of a paper on ‘runaway greenhouse’ Colin Goldblatt, he explains the likelihood of this happening and the timeline associated with Earth losing its oceans.
