New insights into global ocean microbe-virus interactions, drivers of Earth's ecosystems
2015-05-21 12:00:00| LifeSciencesWorld
[NEWS] Hidden among Earth's vast oceans are some of the tiniest and most vital organisms to the health of delicate ecosystems. Ocean microbes produce half of the oxygen we breathe, and are important drivers in chemical reactions and energy transfers that fuel critical ecological processes. Much like other organisms, marine microbes are susceptible to viral infections that can alter their metabolic output, or even kill them. For example, certain ocean viruses invade algae and tak…

Ocean Microbes: How They May Directly Impact Climate Change
2015-05-19 19:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: A team of scientists from UC San Diego and the Scripps Institution of Oceanography reported in the journal ACS Central Science that the process by which marine bacteria consume phytoplankton has an apparent direct role in affecting cloud properties. Phytoplankton are microorganisms that produce molecules that become airborne when they decay - that is, if bacteria don't eat the molecules first. As the bacteria feed, phytoplankton break down into component molecules, such as fats and lipids, which...

Indian Ocean may be key to global warming 'hiatus'
2015-05-19 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature: The Indian Ocean may be the dark horse in the quest to explain the puzzling pause in global warming, researchers report on 18 May in Nature Geoscience1. The study finds that the Indian Ocean may hold more than 70% of all heat absorbed by the upper ocean in the past decade. Scientists have long suspected that oceans have played a crucial role in the so-called warming hiatus by storing heat trapped in the atmosphere by rising levels of greenhouse gases. But pinpointing exactly which ocean acts as...
Ocean Microbes And Climate Change: How Marine Bacteria Are Spurring Global Warming

Business Times: They may be tiny, but they pack a strong punch. Scientists are finding that the smallest ocean organisms can have a major impact on one of the biggest issues of the 21st century climate change. New research has unpacked the role of phytoplankton and ocean bacteria in the formation of sea spray aerosol, the tiny particles that enter the atmosphere and help create the drops of moisture that form clouds, which control earths temperature. It shows that such microbes could actually moderate the chemistry...

Indian Ocean storing up heat from global warming, says study
2015-05-18 19:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The worlds oceans are playing a game of hot potato with the excess heat trapped by greenhouse gas emissions. Scientists have zeroed in on the tropical Pacific as a major player in taking up that heat. But while it might have held that heat for a bit, new research shows that the Pacific has passed the potato to the Indian Ocean, which has seen an unprecedented rise in heat content over the past decade. The new work builds on a series of papers that have tracked the causes for whats been dubbed...
