Updated: 2008-08-12 14:33  An elephant seal is seen with a special sensor fitted to its head in South Georgia in this undated photo released on August 12, 2008 by the Australia's Commonwealth Scientific & Industrial Research Organisation (CSIRO). Elephant seals swimming under Antarctic ice with special sensors fitted to their head are providing scientists with crucial data on ice formation, ocean currents and climate change, said a new study. The seals, which swim under winter ice, have overcome a "blind-spot" for scientists by allowing them to calculate how fast sea ice forms during winter. [Agencies] |
