    The White House Office of Science and Technology Policy, along with the EPA, NOAA, National Institute of Standards and Technology (NIST), and USGS, yesterday announced the launch  of the Nutrient Sensor Ch […]

    • Seems like quite a challenge looking for Nitrates and Phosphates – possibly using Raman Spectroscopy.
      Possibly tickle with a UV laser for
      NO3/Nitrate excited by UV 204nm – resonance output 1104nm

      I wonder if anybody else is thinking about this?
      The UV laser seems to be the biggest challange in a small package, the spectroscope could be doable, and of course the package needs to cope with possible biofouling.

    • @neilh20 Thanks for your comment! A little website glitch here: your hyperlink is keeping the text from wrapping and as a result some of your comment is hidden. If you’d like to edit your comment, you should be able to fix the problem by using this shortened link to the paper: http://bit.ly/1B7QvUg.
