Methods

  • Past Methods (no longer in use)
    • Unnamed Method
      • Started: 1999-06-01
        Ended: 1999-12-31
      • Method Description: On August 19, 1999, a sediment core was acquired from the deep hole in Branch Pond, in the main lake body and in the southmost of two distinct hypolimnetic holes, within the Lye Brook Wilderness Area.

    • Unnamed Method
      • Started: 1999-06-14
        Ended: 1999-12-31
      • Method Description: The core was acquired from a depth of 10.1 meters and capped before breaching the surface. Details of sampling and analysis procedures are documented in Kaman et. al., 1997, Quality Assurance Project Plan, Assessment of Mercury in Hypolimnetic Lake-bed sediments of Vermont and New Hampshire.

    • Data analysis
      • Started: 1999-06-14
        Ended: 1999-12-31
      • Method Description: A REMAP Project. Vt. DEC, Waterbury. Analysis included: %C, %N, statble isotopes (C13, N15), Hg, %solids, loss on ignition (LOI), Pb210.

Sampling Equipment

  • Gravity corer
    • Started: 1999-06-01
      Ended: 1999-12-31
