Unmanned underwater vehicle provides first 3-D images of underside of Antarctic sea ice
A National Science Foundation-funded research team has successfully tested an autonomous underwater vehicle, AUV, that can produce high-resolution, three-dimensional maps of Antarctic sea ice. SeaBED, as the vehicle is known, measured and mapped the underside of sea-ice floes in three areas off the Antarctic Peninsula that were previously inaccessible.

Biology trumps chemistry in open ocean
Scientists laid out a new framework based on in situ observations that will allow them to describe and understand how phytoplankton assimilate limited concentrations of phosphorus, a key nutrient, in the ocean in ways that better reflect what is actually occurring in the marine environment. This is important because nutrient uptake is a property of ocean biogeochemistry, and in many regions controls carbon dioxide fixation, which ultimately can play a role in mitigating climate change.

CT scans of coral skeletons reveal ocean acidity increases reef erosion
For coral reefs to persist, rates of reef construction must exceed reef breakdown. Prior research has largely focused on the negative impacts of ocean acidification on reef growth, but new research this week from scientists at the Hawai'i Institute of Marine Biology, based at the University of Hawai'i - Mānoa, demonstrates that lower ocean pH also enhances reef breakdown: a double-whammy for coral reefs in a changing climate.
