SPACE : This NASA Aqua satellite handout image of millions of tiny ocean plants called phytoplankton received 29 June 2006, shows the bright blue and green swirls that the Moderate Resolution Imaging Spectroradiometer (MODIS) detected off the coast of Vancouver Island, Canada. A giant growth of algae in the waters off Canada’s west coast, so huge it can be seen from space, may be linked to climate change, say scientists who hope to collect samples 30 June 2006.The growth, called a bloom, became visible in late June on NASA satelitte images, said Jim Gower, a physicist with the Institute of Ocean Sciences in Sydney in British Columbia province. Initial reports suggested the bloom could be toxic to humans and wildlife, but these fears have largely been dismissed. The bloom is caused by coccolithphore algae, which leave minute amounts of chalk in the water and which scientists believe created the limestone deposits off England known as the white cliffs of Dover.
