Presentation Transcript

  1. Volunteer NERR WQ stations

  2. Nutrient pollution varies by region Monthly volunteer program at 24 estuarine stations shows that nitrate concentrations vary by region of the slough. Salinas river sites appear to be increasing while reserve sites appear to be decreasing in the last decade. [see http://www.elkhornslough.org/research/waterqualityvolunteer.htm]

  3. Chl Varies by Region too .

  4. Oxygen has remained steady Overall, dissolved oxygen in Slough waters monitored by a continuously deployed water quality sensor at two sites has not changed over the past decade, with low oxygen conditions threatening to wildlife remaining relatively rare. [see http://www.elkhornslough.org/research/waterquality nerrs.htm for more information]
