  • 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 ...

  • Sophisticated soil analysis for improved land use

    Soil variation occurs across multiple geographic scales ranging from vast climatic regions of the Earth to a 50 acre farm field to the molecular world of soil nano-particles in a pinch of soil. For example, in a forest or an agricultural field, soil properties vary from the summit of a hill down to the base. Within a single soil aggregate that may be less than a quarter inch in diameter, there ...

  • Soil microbes hold key to climate puzzle

     Climate scientists puzzled by the traffic of carbon between soil and air may have to think more deeply about the role played by soil microbes − the planet’s smallest inhabitants. One research team has just found that soil microbes could actually lighten the colour of arid land soils, to  ...

  • ASTM D7758 - 11 Standard Practice for Passive Soil Gas Sampling in the Vadose Zone for Source Identification, Spatial Variability Assessment, Monitoring, and Vapor Intrusion Evaluations

    Passive soil gas samplers are a minimally invasive, easy-to-use technique in the field for identifying VOCs and SVOCs in the vadose zone. Similar to active soil gas and other field screening techniques, the simplicity and low cost of passive samplers enables them to be applied in large numbers, facilitating detailed mapping of contamination across a site, for the purpose ...

  • How Grazinglands influence greenhouse gas

    Grazinglands represent one of the largest land resources in the world, yet their role as net sinks or sources of greenhouse gases is essentially unknown. Previous research has emphasized the role of grazing management on the sequestration of atmospheric carbon dioxide as soil organic carbon. However, there is a lack of information regarding how grazing management impacts the flux of two potent ...

  • Gas analysis workshop focuses on FTIR versatility

    Gasmet Technologies, the manufacturer of FTIR gas analyzers, organised a meeting in Lisbon, immediately prior to the CEM 2016 conference and exhibition in May, to provide delegates with an insight into the wide variety of applications for which FTIR technology is employed. The measurement of greenhouse gases (GHGs) was a particular focus for the event, with presentations from a number ...

  • Continuous Ground Gas Monitoring Technical Article

    It is almost inevitable in the initial phases of a construction sites development, that a Ground Gas risk assessment process is required by the local planning authority, and subsequently undertaken by a developer or their contractor. This normally encompasses spot monitoring visits that can last up to 12 months or more, if methane is found at over 5% by volume. However, it is important to realise ...

  • 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 ...

  • Greenhouse Gas Report to Assist Producers Facing Climate Challenges

    The U.S. Department of Agriculture (USDA) today released a report that, for the first time, provides uniform scientific methods for quantifying the changes in greenhouse gas emissions (GHG) and carbon storage from various land management and conservation activities. The report, titled Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry: Methods for Entity-Scale Inventory, will help ...

  • 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 ...
