Antarctica: The story behind the ice
The influence of ocean currents in climate change and the story behind Antarctica’s icy ambience, is unraveled by ancient fish teeth// that seem to be holding the clue. ..An element pretty unheard of and extremely rare, identified in the tiny fish teeth has offered a clue to the University of Florida geologists in estimating the period when the passage between Atlantic and Pacific might have op...Rising sea-levels could cause the Antarctic ice sheet to break up, even though the air over it will remain chilly enough to prevent significant melting for at least a century, according to a new study by a researcher from Victoria University of Wellington, New Zealand. ......As part of their study, the team led by Andrew Mackintosh gauged the ice sheet's past thickness by measuring how high the...Antarctica's icebergs have a major impact on the ecology of the ocean around them, serving as 'hotspots' for ocean life, according to a new study by American researchers. ......The icebergs hold trapped terrestrial material, which they release far out at sea as they melt. This process produces a "halo effect" with significantly increased nutrients, chlorophyll and krill out to a radius of more t...
