Dataset: Mercury and Dissolved Organic Carbon in Soil Water

Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Past Methods (No longer in use)

• Stream sample sites and measurements
  Started: 1997-04-12
  Ended: 1997-11-02

  Stream sample sites -- Nettle Brook at 1620 and 1720' elevations and Stream 10 on CCC road at 2560'. Soil water and stream water samples collected after 5 storms. Twelve soil water collectors distributed in three areas (two at the O horizone and two at the B horizone per area). Stream samples collected near soil water collectors. Soil and stream water measurements include: total Hg, pH, conductivity, DOC and color, major ions (Ca, K, Mg, Na, Cl, NH4, NO3, SO4, and PO4.

Dataset Fields

Detailed documentation of the fields comprising the dataset, including the type of measurement, units where applicable, and any controlled vocabularies or code lists present in the data

Sampling Equipment

Equipment and software used to collect data, including how that equipment was used.

Current Equipment

• Fiberglass Wick Sampler
  
  

  Fiberglass Wick Sampler- samples water and solutes moving through the unsaturated layers in soil by using fiberglass wicks to collect water by capillary action.

• Lysimeter
  
  

  Zero-tension Lysimeter- collects solution that moves downward through the soil by force of gravity, often through micropores.

Site Characteristics

The spatial extent of the dataset site coverage, and descriptions of the spatial extent and context for the data collection

• Site Description

  Stream 10 (Browns River drainage, on the CCC road), drains a 7.4 ha mixed conifer and hardwoods catchment
• Site Description

  West slope of Mount Mansfield in the Nettle Brook (Stevensville Brook drainage); the stream drains an 11 ha mixed hardwoods catchment
