  6. Data and Analysis

  7. Data and Analysis Figure 4: Nitrate/Nitrite Concentrations Downstream (Station 140) Neponset River

  8. Data and Analysis Figure 5: Phosphate Concentrations Downstream (Station 140) Neponset River

  9. Second Step: NLOAD Web-based Model • http://nload.mbl.edu/index.php

  10. NLM Model: • Estimates nitrogen input from different land uses Huang & Chen 2009

  11. Nload Inputs Nload Outputs

  12. Data and Analysis

  13. What’s next? • Refine inputs and weighting in models • Delve deeper, more fine-scaled analysis • For the eelgrass: More sample sites
