    Methods

    • Past Methods (no longer in use)
      • Sites
        • Started: 2002-10-01
          Ended: 2006-09-30
        • Method Description: 10 headwater catchments were sampled for nitrogen flux.

      • Chemical analysis sampling
        • Started: 2002-10-01
          Ended: 2006-09-30
        • Method Description: Weekly sampling was used for chemical analysis at Cone Pond and HBEF W7. At the other sites sampling was flow based using automated samplers but also included weekly to monthly grab samples.

      • Stream stage monitoring
        • Started: 2002-10-01
          Ended: 2006-09-30
        • Method Description: Stream stage was continuously monitored using V notch weirs at Cone Pond, HBEF W7, Brush Brook, Buck North and Sleepers River, and natural controls at the other sites. Stage was converted to discharge for sites with natural controls.

      • Nitrate flux calculation
        • Started: 2002-10-22
          Ended: 2006-09-30
        • Method Description: Daily water flux and weekly NO3 concentrations were used to calculate annual NO3 export at Cone Pond and HBEF W7. Nitrate flux at Sleepers River, Brush Brook and Lye was computed using concentration models based on instantaneous flow, antecedent flow, and seasonal terms.
