Beached iceberg helps reveal ecological impact of sea-ice changes
Sydney, Australia (SPX) May 22, 2015
The grounding of a giant iceberg in Antarctica has provided a unique real-life experiment that has revealed the vulnerability of marine ecosystems to sudden changes in sea-ice cover. UNSW Australia scientists have found that within just three years of the iceberg becoming stuck in Commonwealth Bay - an event which dramatically increased sea-ice cover in the bay - almost all of the seaweed on the sea floor had decomposed, or become discoloured or bleached due to lack of light. "Understanding the ec ... read more
