Most of the world’s oceans are already depleted to the extent that they can’t support the demand. So, it’s finally time to tap into the last and most remote corner of the ocean world. Photo: John Weller There is a large scale attempt to stop the exploitation of this region. If y...
has provided new information on the processes that cause climate to change. A deep coring hole at the Russian station Vostok brought up a climate and fallout history extending back more than 400,000 years. A huge freshwater lake lies between the ice and the bed at this location.Lake Vostokha...

Because of Antarctica's harsh environment and remote location, there is less data available to unequivocally link events such as these with human-induced climate change. But Prof Siegert said: "I think it's reasonable to assume that with the Antarctic heat ...
Cemphasise the significance of Antarctica to the global climate and ocean currents. Dillustrate the geographical location of Antarctica as the central spot on Earth. 23Why should Australian farmers keep an eye on the Antarctic ocean temperature?
Antarctica has not always been covered in ice. At numerous times in its geologic history, the continent was warmer due to a more equatorial location and differingpaleoclimates. It is not rare to find fossil evidence of vegetation anddinosaurson the now-desolate continent. The most recent large-...

Antarctica, and particularly the South Pole, attracts much interest in astronomical and astrophysical studies as well as research on the interactions between the Sun and the upper atmosphere of Earth. The South Pole is auniqueastronomical location (a station from which the Sun can be viewed continu...
