Two New Views Of Carbon Sinks
2012-08-02 05:35:15

April Flowers for redOrbit.com - Your Universe Online In the last 50 years, man has quadrupled his CO2 output, primarily through the burning of fossil fuels. That is a startling and sobering concept. So far, though, Mother Nature seems to be keeping pace. In a new study released August 2, 2012, in the journal Nature, researchers from NOAA and the University of Colorado assert that Earth's carbon sinks continue to soak up roughly half of the carbon output. Carbon sinks are areas of...

As Area Burned By Wildfire Increases Washington's Forests Will Lose Stored Carbon
2012-07-26 10:33:45

Even small increases in area burned could have significant impacts on carbon storage Forests in the Pacific Northwest store more carbon than any other region in the United States, but our warming climate may undermine their storage potential. A new study conducted by the U.S. Forest Service's Pacific Northwest Research Station and the Climate Impacts Group at the University of Washington has found that, by 2040, parts of Washington State could lose as much as a third of their carbon...

Rising Carbon Dioxide In Atmosphere Speeds Carbon Loss From Forest Soils
2012-07-10 15:29:04

Underappreciated player in carbon storage should be included in global change models, researcher says Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found. The new evidence supports an emerging view that although forests remove a substantial amount of carbon dioxide from the atmosphere, much of the carbon is being stored in living woody biomass rather than as dead organic...

Researchers Measure Carbon In The Arctic Ocean
2012-05-22 03:59:49

Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean´s carbon cycle–the pathway through which carbon enters and is used by the marine ecosystem. It will also offer an important point of reference for determining how those levels of carbon...

Image 1 - Carbon-Counting Instrument Travels To Arizona
2012-05-12 04:21:07

Its construction now complete, the science instrument that is the heart of NASA's Orbiting Carbon Observatory-2 (OCO-2) spacecraft - NASA's first mission dedicated to studying atmospheric carbon dioxide - has left its nest at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and has arrived at its integration and test site in Gilbert, Ariz. A truck carrying the OCO-2 instrument left JPL before dawn on Tuesday, May 9, to begin the trek to Orbital Science Corporation's Satellite...

Life deep in the seabed proceeds very slowly. But the slow-growing bacteria living many meters beneath the seafloor play an important role in the global storage of organic carbon and have a long-term effect on climate. A team of scientists from Aarhus University (Denmark) and the University of Rhode Island have developed a new method for measuring this slow life deep down in the seabed. According to URI Oceanography Professor Arthur Spivack, the relative abundance of amino acids that are...

New method for measuring slow life in the seabed can provide knowledge about the global carbon cycle "Mud samples boiled in acid sounds like witchcraft," admits microbiologist Bente Lomstein from the Department of Bioscience when explaining how she and an international group of researchers achieved the outstanding results being published today in the journal Nature. Bacteria are the only living organisms to produce D-amino acids that deposit a chemical signature in the mud in which they...

The most comprehensive dataset of surface water carbon dioxide (CO2) measurements for the world's oceans and coastal seas is launched today by an international team of scientists led by the University of East Anglia (UEA). The Surface Ocean CO2 Atlas (SOCAT) comprises 6.3 million global observations made from research vessels, commercial ships and moorings around the world since 1968. The dataset documents the changes in ocean carbon similar to the Mauna Loa record — or 'Keeling...

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...

A new study comparing the carbon-holding power of freshwater wetlands has produced measurements suggesting that wetlands in temperate regions are more valuable as carbon sinks than current policies imply, according to researchers. The study compared several wetlands at two Ohio wetland sites: one composed of mostly stagnant water and one characterized by water regularly flowing through it. The study showed that the stagnant wetland had an average carbon storage rate per year that is almost...
