One proposed strategy to combat the buildup of carbon dioxide in the atmosphere is to pump it to the seafloor. To find out how that might affect life on the seafloor, WHOI geobiologist Joan Bernhard (above, green jacket) and Kurt Buck of Monterey Bay Aquarium Research Institute used the MBARI robotic vehicle Tiburon to push cylinders (right) into seafloor sediments more than 3,000 meters deep in Monterey Bay, Calif. They injected a carbon dioxide hydrate slurry into the sediments and retrieved the samples a month later. Organisms collected from the sediments were stained with a green fluorescent dye that appears (under ultraviolet light) only in living specimens. Microscopic images (at right, bottom) showed that some shell-less organisms survived high levels of carbon dioxide, but no species that form calcium carbonate shells survived.
