New discovery of how carbon is stored in the Southern Ocean

July 29, 2012 - via British Antarctic Survey Due to the size and remote location of the Southern Ocean, scientists have only recently been able to explore the workings of the ocean with the help of small robotic probes – known as Argo floats. In 2002, 80 floats were deployed in the Southern Ocean to collect information on the temperature and salinity. This unique set of observations spanning 10 years has enabled scientists to investigate this remote region of the world for the first time.

Robot 'Mermaids' Swim Seas to Detect Seismic Waves

October 13, 2011 - via OurAmazingPlanet Each robot is known as a Mobile Earthquake Recorder in Marine Areas by Independent Divers, or Mermaid. They are equipped with hydrophones, or underwater microphones, with which they record seismic waves from quakes and other earth-shaking phenomena as they ripple through the water. The mics can pick up the waves of quakes from as far away as 7,450 miles (12,000 km).
