  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Persistent Organic Pollutants (POPs) in the European Atmosphere: An Updated Overview

    The industrial revolution and the resultant technological society have led to a continuous production and emission of new toxic substances causing gradual and widely diffuse adverse effects to the entire planet usually known as Global Environmental Changes. Climate change, ozone depletion and global distribution of persistent organic pollutants (POPs) are, among other, important examples of ...


  • Ocean science for sustainable development: Facts and figures

    Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

  • CU-Boulder leading study of wind turbine wakes

    While wind turbines primarily are a source of renewable energy, they also produce wakes of invisible ripples that can affect the atmosphere and influence wind turbines downstream -- an issue being researched in a newly launched study led by the University of Colorado Boulder's Julie Lundquist, assistant professor in the atmospheric and oceanic sciences department. The study, called the Turbine ...


  • A marked improvement in the reliability of the measurement of trace moisture in gases

    Introduction Water is an important substance without which mankind cannot survive. However, it also causes problems such as residual impurity in scientific experiments and in manufacturing processes where a high-vacuum condition or a high-purity gas is required. This is because water is present in the atmosphere in large quantities and therefore can intrude readily everywhere, and can adsorb ...

  • Remote sensing of particulate pollution from space: Have we reached the promised land?

    This paper follows presentation and publication of the Hoff and Christopher 2009 Critical Review and represents an integration of discussants’ views of their paper. The discussants’ comments are organized beginning with a note on the history of satellite sensing, followed with a brief discussion of the strengths and weaknesses of satellite observations relative to air quality management needs. ...

  • Accuracy and precision analysis of chamber-based nitrous oxide gas flux estimates

    Chamber-based estimates of soil-to-atmosphere nitrous oxide (N2O) gas flux tend to underestimate actual emission rates due to inherently nonlinear time series data. In theory, this limitation can be minimized by adjusting measurement conditions to reduce nonlinearity and/or by using flux-calculation (FC) schemes that account for the so-called 'chamber effect.' The current study utilizes gas ...

  • Are Solar Powered Drones The Way Forward?

    Just recently, Titan Aerospace released a video of a solar-powered drone that will be put through rigorous testing later on this year. Named the Solara 50, the drone can theoretically fly without having to land constantly to fuel up. The implications are numerous – from the fact that a drone that does not need to land can be used in the name of science, to the possibility that it might be ...

  • NASA campaign KORUS-AQ: IONICON PTR-TOF to monitor VOCs above Korea

    Team of the University of Innsbruck and an IONICON PTR-TOFMS aboard NASA research aircraft An international team coordinated by NASA has recently investigated air pollution over the Korean peninsula. Two of IONICON’s PTR-TOFMS instruments were used to monitor volatile organic compounds (VOCs) in real-time aboard NASA’s DC-8 Flying Laboratory. The data gathered by scientists ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Algiz XRW Assists scientists on the Frozen arctic sea - Case Study

    With help from the Algiz XRW portable rugged notebook computer from Handheld Group, two scientists hosted the Arctic Science Field Logistics project from autumn to spring 2013-14, providing researchers from around the world a unique opportunity to collect scientific data in a remote Arctic location. This rugged notebook assisted with recording and storing scientific data, keeping open lines of ...

  • Ocean carbon: A dent in the iron hypothesis

    Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the ...

  • Combating Corrosion - Committee G01 Standards Fight Nature’s Destructive Tendencies

    The evening news may leave many of us feeling war-weary, but one ASTM International technical committee has been successful in conflict of a different sort. It’s a commonplace but epic struggle between the natural and civilized worlds — the fight against metal corrosion. For the past half-century, the weapon of choice of ASTM Committee ...
