April Flowers for redOrbit.com - Your Universe Online In a region of the Southern Ocean, iron fertilization caused plankton to thrive during the last ice age, according to a new study from Princeton University and the Swiss Federal Institute of Technology in Zurich. The findings, published in Science, confirm a longstanding theory that wind-borne dust carried iron to this region of the Antarctic. This iron dust drove plankton growth and eventually led to the removal of carbon dioxide...

Ocean Fertilization Suffocates Carbon, Reduces Climate Change

Lawrence LeBlond for redOrbit.com - Your Universe Online The negative impact of climate change might be avoided by dumping massive amounts of iron into the world´s oceans, which smothers carbon dioxide for centuries, according to an international team of researchers who have recently published results of an ocean iron fertilization experiment (EIFEX) carried out in 2004. The new study, published in the science journal Nature, shows that sowing the ocean with iron particles sucks up...

Phytoplankton Key to a Healthy Planet says Canada Research Chair at the Forefront of Phytoplankton Research Maria (Maite) Maldonado, Canada Research Chair in Phytoplankton Trace Metal Physiology at The University of British Columbia, has made understanding the intricacies of marine phytoplankton her life's work. These tiny, single-celled algae, which act as a natural sponge for carbon dioxide and are a critical part of the global carbon cycle, may play a key role in ensuring the health of...

Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions.Tiny plant-like organisms called phytoplankton dominate biological production in the sunlit surface waters of the world's oceans and, through the process of photosynthesis, sequester large amounts of atmospheric carbon dioxide. A proportion of the carbon is...

WASHINGTON, May 28 /PRNewswire-USNewswire/ -- Researchers have conducted the first global analysis of the health and productivity of ocean plants using a unique signal detected by NASA's Aqua satellite. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Ocean scientists can now remotely measure the amount of fluorescent red light emitted by phytoplankton and assess how efficiently these microscopic plants turn sunlight and nutrients into food through photosynthesis. Researchers...

U.S. government oceanographers say they've determined plankton carbon particles in the Southern Ocean never reached the deep ocean. Jim Bishop and Todd Wood of the U.S. Department of Energy's Lawrence Berkeley National Laboratory studied the fate of carbon particles originating in plankton blooms using data deep-diving Carbon Explorer floats collected around the clock for more than a year. The discovery that most of the carbon never reaches the deep ocean deals a blow to the simplest version...

Plankton blooms do not send atmospheric carbon to the deep ocean Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy's Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the deep ocean. The surprising...
