dataset_eml_methodsheader

  • dataset_eml_currentMethodsHeader
    • Monitoring streamflow
      • dataset_eml_methoddescription: Streamflow at the mouth of the catchment is monitored by a US Geological Survey weir. Stage is recorded at 5 minute intervals. Stream discharge was calculated from the stage above the 90 degree v-notch weir. Air, water, soil, and snowpack temperatures as well as snowpack depth and reflected short radiation were also recorded at the site of the weir.

    • Air quality monitoring station data
      • dataset_eml_methoddescription: Wet and dry deposition inputs and ambient meteorological data were measured at the VMC air quality monitoring station, located approximately 2 km away at about the same elevation as the weir.

    • Sampling snowpack
      • dataset_eml_methoddescription: The snowpack was sampled near the weir at three depths, two weeks before the start of the spring snowmelt event.

      • dataset_eml_samplingdescription: Campbell Scientific CR-10 used to record stage at 5-minute intervals.

    • Spectrometer
      • dataset_eml_samplingdescription: Leeman 2.5 Plasma Spec was used for analysis of cations.

dataset_eml_sitecharacteristicsheader

  • dataset_eml_sitecharacteristicsdescription: Nettle Brook, the study site catchment area, is located on the southwest slope of Mount Mansfield in the Green Mountains of northern Vermont. The drainage basin of the catchment has an estimated area of 0.11 km^3 and is drained by a small first-order stream, Nettle Brook.



  • dataset_eml_sitecharacteristicsdescription: The catchment elevation extends from 445 m to 665 m above sea level. The bedrock in this area is predominantly mica-albite-quartz schist and the soils are dominated by Peru extremely stony loam, Marlow extremely stony loam, Cabot extremely stony silt loam and Lyman-Marlow very rocky loam.



  • dataset_eml_sitecharacteristicsdescription: Nettle Brook flows intermittently from east of the boggy area, and year round west of the boggy area. Nettle Brook is groundwater dominated except during floods.
