  • Microbial Biodiversity Detection And Monitoring Using Molecular Biology Tools

    Micro-organisms are responsible for the most biogeochemical cycles that shape the environment of earth and its oceans. So far, only part of these organisms has been well studied, especially those living on earth and more considered from an anthropogenic perspective, e.g causing human diseases or providing useful products and services. Further the inability to generate pure culture has hampered ...


  • 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 ...

  • Using Benthic Macroinvertebrates to Assess Ecological Status of Lakes Current Knowledge And Way Forward to Support WFD Implementation

    Directive 2000/60/EC, commonly known as the Water Framework Directive (WFD) has initiated achange in both the concept of water quality and its assessment throughout Europe. It has started a shift from the mindset of Europe’s water resource being a product which may be monitored chemically to ensure its suitability for human use to one that regards water as a heritage. A more holistic assessment ...


  • Analysis of Anionic Contamination & General Quality Testing in Water from Sewage Treatment Plants and Industrial Discharge & Effluents by Colorimetry

    Problem The high concentration of Industry, Agriculture and People in and around the United States has changed the “nature” of our environment. There are Toxic Metals coming from various metallurgical processes; Plating, Foundry, Smelting, Milling, etc., which are readily determined by Atomic Absorption Spectroscopy (AAS). Volatile Organics from the many Petrochemical-based operations are ...

  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • 400 PPM: Carbon dioxide levels cross a sobering new threshold

    Last week we passed an unfortunate marker when it comes to climate change: concentrations of carbon dioxide (CO2) in the atmosphere have hit 400 parts per million (ppm) near the Arctic. What Does it Mean and Why Should We Care? This ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

  • 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 ...

  • SolarBee Technical Bulletin

    A. SOLARBEE OVERVIEW 1. Origin of the SolarBee. Pump Systems, Inc. (PSI) developed, built and installed its first solar powered mixer in Dickinson, ND, in the summer of 1998. It was installed into a 30 acre x 13 foot deep municipal wastewater reservoir which had a long history of toxicity associated with ammonia, odor, and stratification problems. In six weeks the entire reservoir cleared up to ...
