An international group of scientists, including researchers from the Woods Hole Oceanographic Institution, are working to improve communication about ocean acidification to help the public better understand the pressing global issue.
The term “ocean acidification” (OA) describes the changes that occur in the ocean as a result of increased emissions of carbon dioxide (CO2) into the atmosphere. The rising acidic level in the ocean puts certain organisms at risk and threatens the overall health of the ocean. (more…)
NASA’s UCLA-led Dawn mission shows protoplanet’s surprising surface
When UCLA’s Christopher T. Russell looks at the images of the protoplanet Vesta produced by NASA’s Dawn mission, he talks about beauty as much as he talks about science.
“Vesta looks like a little planet. It has a beautiful surface, much more varied and diverse than we expected,” said Russell, a professor in UCLA’s Department of Earth and Space Sciences and the Dawn mission’s principal investigator. “We knew Vesta’s surface had some variation in color, but we did not expect the diversity that we see or the clarity of the colors and textures, or their distinct boundaries. We didn’t find gold on Vesta, but it is still a gold mine.”
Dawn has been orbiting Vesta and collecting data on the protoplanet’s surface since July 2011. Vesta, which is in the doughnut-shaped asteroid belt between Mars and Jupiter, is currently some 321 million miles from Earth. (more…)
