Icy Seas Continue in Antarctica

Sea water under an East Antarctic ice shelf showed no sign of higher temperatures despite fears of a thaw linked to global warming that could bring higher world ocean levels, first tests showed on Monday. Sensors lowered through three holes drilled in the Fimbul Ice Shelf showed the sea water is still around freezing and not at higher temperatures widely blamed for the break-up of 10 shelves on the Antarctic Peninsula, the most northerly part of the frozen continent.

Ohio State Glaciologist Team Gets Important Ice Cores in Andes

Ice cores are important tools to identify Earth’s past climate. They enable us to peer back in time to identify species of insects trapped in ice as well as isotopes oxygen and dust particles that were deposited at various time in the past. The ratio of oxygen isotopes in the ice allows researchers to determine whether temperatures were warmer or cooler when the snow that eventually turned to ice was deposited on the glacier
