Computational model offers insight into mechanisms of drug-
coated balloons. Deep-sea sediments could provide a virtually
unlimited and permanent reservoir for carbon dioxide, the gas
that has been a primary driver of global climate change in
recent decades, according to a team of scientists that includes
a professor from MIT. The researchers estimate that seafloor
sediments within U.S. territory are vast enough to store the
nation's carbon dioxide (CO2) emissions for thousands of years
to come. "The exciting thing about this paper is that we show
that CO2 injected beneath the seafloor is sequestered
permanently," said Charles Harvey, an associate professor in
MIT's Department of Civil and Environmental Engineering. Harvey
is a co-author of a paper on the work that appears in this
week's issue of the Proceedings of the National Academy of
Sciences. "CO2 injected underground on land isï¿½ï¿½buoyant, and
hence has the potential to escape back to the surface," Harvey
said. "This is not the case under the deep oce
