  • The cold deep currents in the Atlantic Ocean that help shape our climate

    For more than a decade scientists from the National Oceanography Centre in Southampton have been travelling to the subtropical Atlantic to collect data that provide important information about our changing climate. Just 15 miles from the sandy shores and coral reefs of the Bahamas the ocean floor plunges down to depths of over two-and-a-half miles. Along this steep slope dozens of sensitive ...

  • Bringing life back to dead zones

    Dead zones — those regions that can be found in the Great Lakes, Chesapeake Bay, and even the Gulf of Mexico — are a serious problem for U.S. waterways. These hypoxic zones, the result of excess nitrogen and phosphorus run off, can lead to algae blooms that can stifle aquatic life. Regulators are doing their part to reduce these dead zones by mandating the decrease of nutrient runoff ...

  • Photometry Compendium - Episode 6 is live!

    Besides the methods that use a chemical reaction to create a concentration dependant colour change, which can then be measured, there are many substances that can be measured without a colour reaction provided they absorb light within the wave length range of the photometer. To date, used exclusively in water treatment plants, a technique is available which is able to detect several parameters ...

  • Des Moines struggling with nitrates in water

    Two rivers that supply water to 500,000 people in the Des Moines area show nitrate levels spiking to levels that make it unsafe for some to drink, a concentration experts haven't before seen in the fall that likely stems from especially wet weather in recent months. The utility that supplies Des Moines and most of its suburbs had workers blending river water with other sources to lower the ...
