British Antarctic Survey Press Release
.....Professor Peck and his colleagues compared records of coastal glacial retreat (round the NW Arctic Peninsula) with records of the amount of chlorophyll (green plant pigment essential for photosynthesis) in the ocean. They found that over the past 50 years, melting ice has opened up at least 24,000 km2 of new open water (an area similar to the size of Wales) – and this has been colonised by carbon-absorbing phytoplankton. According to the authors this new bloom is the second largest factor acting AGAINST climate change so far discovered on Earth (the largest is new forest growth on land in the Arctic).
Professor Peck continues, "Elsewhere in the world human activity is undermining the ability of oceans and marine ecosystems to capture and store carbon. At present, there is little change in ice shelves and coastal glaciers away from the Antarctic Peninsula, but if more Antarctic ice is lost as a result of climate change then these new blooms have the potential to be a significant biological sink for carbon.".....
