  • Los Gatos Research Now Offers Ten Ultraportable Analyzers for Soil Trace Gas Flux Measurements

    Los Gatos Research (LGR), the leader in precision trace gas analyzers, today announced that it has expanded the lower speed (up to 1 Hz) trace gas analyzer line to include as many as nine different Ultraportable trace gas analyzers with various combinations available in ten different products. This year's R&D 100 Award winning analyzer for NO2 (nitrogen dioxide) joins a series of 1 Hz ...

  • LI-COR Analyzers Monitoring Carbon Dioxide Worldwide as Atmospheric Levels Reach 400 parts per million

    On May 13, the National Oceanic and Atmospheric Administration (NOAA) reported a preliminary daily average carbon dioxide (CO2) reading of 400.07 parts per million (ppm) at the Mauna Loa Observatory on the Big Island of Hawaii. On May 9, a reading over 400 ppm was reported at the site for the first time ever. But that reading (400.03 ppm) was later revised to 399.89 ppm. The first CO2 ...

  • Even soil feels the heat

    Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in this week's issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which ...

  • Typhoons bury tons of carbon in the oceans

    A single typhoon in Taiwan buries as much carbon in the ocean - in the form of sediment - as all the other rains in that country all year long combined. That's the finding of an Ohio State University study published in a recent issue of the journal Geology. The study - the first ever to examine the chemistry of stream water and sediments that were being washed out to sea while a typhoon was ...


  • LI-COR Introduces New Multiplexer for Automated Soil CO2 Studies

    Lincoln, Nebraska: LI-COR Biosciences now offers an automated solution for assessing spatial as well as temporal variability in CO2 flux. The new LI-8150 Multiplexer expands the capabilities of the company’s LI-8100 Automated Soil CO2 Flux System by allowing up to 16 chambers to be controlled by a single LI-8100 Analyzer Control Unit. The LI-8100 is an economical and lightweight system for ...

  • Global warming’s ecosystem double whammy

    Plants and soils act like sponges for atmospheric carbon dioxide, but new research finds that one abnormally warm year can suppress the amount of carbon dioxide taken up by some grassland ecosystems for up to two years. The findings, which followed an unprecedented four-year study of sealed, 12-ton containerized grassland plots at DRI is the cover story in the September 18 issue of the ...

  • Greenhouse Gas Concentrations Reach New Record

    The amount of greenhouse gases in the atmosphere reached a new record high in 2011, according to the World Meteorological Organization. Between 1990 and 2011 there was a 30% increase in radiative forcing – the warming effect on our climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases. Since the start of the industrial era in 1750, about 375 billion tonnes ...

  • Can biochar help suppress greenhouse gases?

    Nitrous oxide is a potent greenhouse gas and a precursor to compounds that contribute to the destruction of the ozone. Intensively managed, grazed pastures are responsible for an increase in nitrous oxide emissions from grazing animals’ excrement. Biochar is potentially a mitigation option for reducing the world’s elevated carbon dioxide emissions, since the embodied carbon can be ...

  • The mathematics of leaf decay

    A mathematical model reveals commonality within the diversity of leaf decay. Written by Jennifer Chu, MIT News Office. You can read the original story in MIT News The colorful leaves piling up in your backyard this fall can be thought of as natural stores of carbon. In the ...

  • Unique compact and ultra-portable GHG analyzer enables in-situ measurements anywhere

    Los Gatos Research (LGR), the leader in precision trace gas analyzers, has introduced the world’s first ultra-portable greenhouse gas (GHG) analyzer, which reports methane, carbon dioxide and water vapor with parts per billion precision and accuracy in a rugged, crush-proof and compact package. This new Ultra-portable Greenhouse Gas Analyzer (UGGA) simultaneously measures CO2, CH4 and H2O ...

  • Straw cover trims emissions of specific gases from Slurry

    Odor complaints related to animal production have increased during the past decade. Swine slurry stored in open storages is a source of airborne contaminants, including ammonia and odorous compounds. A customary practice for ammonia and odor control consists of covering the surface of the slurry with floating materials, such as straw. In general terms, straw covers reduce odorant emissions from ...
