Trillions of cubic feet of natural gas are thought to lie in cold storage within Earth’s permafrost and under its oceans. That gas, however, is trapped within cage-like chemical structures called methane clathrates. Scientists are very interested in these structures, because they may have cousins hidden under the surface of the icy moons in the outer solar system.
Researchers at Georgia Tech, Scripps Institution of Oceanography, the Smithsonian Institution, and Stanford University are leading an initiative to ensure the health of oceans for generations to come. Called OceanVisions, the initiative envisions healthy oceans for all inhabitants of Earth and for all users and uses of the open seas enabled by advances in science and engineering.
Georgia Tech now offers an interdisciplinary Ph.D. program in Ocean Science and Engineering. The new program aims to train ocean scientists and engineers by combining basic and applied sciences with innovative ocean technologies.
In ocean expanses where oxygen has vanished, newly discovered bacteria are diminishing additional life molecules. They help make virtual dead zones even deader. Now, a team led by the Georgia Institute of Technology has discovered members of a highly prolific bacteria group known as SAR11 living in the world’s largest oxygen minimum zone. The team has produced unambiguous evidence that the bacteria play a major role in denitrification.
