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...

Much of our knowledge about past life has come from the fossil record — but how accurately does that reflect the true history and drivers of biodiversity on Earth? "It's a question that goes back a long way to the time of Darwin, who looked at the fossil record and tried to understand what it tells us about the history of life," says Shanan Peters, an assistant professor of geoscience at the University of Wisconsin—Madison. In fact, the fossil record can tell us a great...

Changes in global carbon, sulfur cycles and to sea-level fueled biological responses Much of our knowledge about past life has come from the fossil record, but how accurately does that record reflect the true history and drivers of biodiversity on Earth? "It's a question that goes back a long way to the time of Darwin, who looked at the fossil record and tried to understand what it tells us about the history of life," says Shanan Peters, a geoscientist at the University of...

Atmospheric carbon dioxide (CO2) is one of the most important greenhouse gases and the increase of its abundance in the atmosphere by fossil fuel burning is the main cause of future global warming. In past times, during the transition between an ice age and a warm period, atmospheric CO2 concentrations changed by some 100 parts per million (ppm) — from an ice age value of 180 ppm to about 280 ppm during warm periods. Scientists can reconstruct these changes in the atmospheric carbon...

U.S. scientists have developed a new, integrated, ten-year science plan to better understand the details of Earth's carbon cycle and people's role in it. Understanding the carbon cycle is central for mitigating climate change and developing a sustainable future. The plan builds on the first such plan, published in 1999, but identifies new research areas such as the role of humans as agents and managers of carbon cycling and climate change, the direct impact of greenhouse gases on ecosystems...
