Robot Offers Rare Glimpse Into Antarctica's Colorful Underwater World

Scientists from the Australian Antarctic Division sent a Remotely Operated Vehicle (ROV) down to take a look under the ice in east Antarctica, capturing a small forest of underwater organisms in bright purples, yellows, and pinks. The organisms survive in water that 29.3 degrees Fahrenheit and covered in thick sea ice for most of the year. The research team is collecting data about sea water acidity, salinity, and temperature to help them understand how the region will be affected by climate change - particularly ocean acidification.
