Tiny plankton could have big impact on climate

ScienceDaily: As the climate changes and oceans' acidity increases, tiny plankton seem set to succeed. An international team of marine scientists has found that the smallest plankton groups thrive under elevated carbon dioxide (CO2) levels. This could cause an imbalance in the food web as well as decrease ocean CO2 uptake, an important regulator of global climate. The results of the study, conducted off the coast of Svalbard, Norway, in 2010, are now compiled in a special issue published in Biogeosciences, a journal...
Volcanic ash triggers plankton bloom

BBC: The 2010 Icelandic volcanic eruption, which disrupted European flights, also had a "significant but short-lived" impact on ocean life, a study shows. Ash from the Eyjafjallajokull volcano deposited dissolved iron into the North Atlantic, triggering a plankton bloom. The authors said it was good fortune they were at sea at the time as it provided a unique opportunity to sample the ocean during a volcanic eruption. The findings appear in the Geophysical Research Letters journal. In April...

Ocean plankton sponge up nearly twice the carbon currently assumed

ScienceDaily: Models of carbon dioxide in the world's oceans need to be revised, according to new work by UC Irvine and other scientists published online Sunday in Nature Geoscience. Trillions of plankton near the surface of warm waters are far more carbon-rich than has long been thought, they found. Global marine temperature fluctuations could mean that tiny Prochlorococcus and other microbes digest double the carbon previously calculated. Carbon dioxide is the leading driver of disruptive climate change. In...

Plankton Can Respond To Climate Change
2013-03-10 16:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Inquisitr: Plankton species can adapt to changing water temperatures, allowing them to swim efficiently even in colder, heavier water, according to a team of Texas researchers who recently published their results in the Proceedings of the National Academy of Sciences. That`s important because the tiny organisms are one of the most important food sources in the ocean`s food web. Even large animals like whales and some plankton-eating sharks depend on huge accumulations of these microscopic creatures to survive....

Sailors to help measure plankton
2013-02-23 09:27:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Scientists are enlisting sailors and fishermen to help with what they hope will be the world's biggest study of plankton in the oceans. Plankton are microscopic organisms, key to the marine food chain, but research suggests they are in decline. Researchers at Plymouth University's Marine Institute want seafarers to help measure the quantity of plankton. The results will "help us understand how life in the oceans is changing", said project leader, Dr Richard Kirby. Scientists fear that...
