Chamber gas flux and water chemistry data, 2012, Prudhoe Bay, Alaska.

Wickland, Kimberly

This dataset contains information obtained from the Prudhoe Bay field site in 2012. Eighteen gas flux measurements locations were established along a transect that included terrain classified according to state of ice wedge degradation. Gas flux measurement and water chemistry analyses were also performed in 16 inundated troughs, or ponds, and 3 lakes near the transect. Flux measurements of methane (CH4) and carbon dioxide (CO2) were made; a total of 201 CH4 flux measurements, and 331 CO2 flux measurements were made. Water samples were collected from soil pore waters where available, and from ponds and lakes on select field campaigns, for a total of 52 samples.

Variablen [Einheiten]
  1. Site name: Site name = "Prudhoe Bay"
  2. Plot name: Name assigned to each sampling point; a combination of letters (describing landform type) and a number
  3. Date: Measurement date
  4. Time: Measurement time (when gas flux measurement began)
  5. Flux Chamber Type: "Dark" = opaque chamber on soil; "Light"= transparent chamber on soil; "Dark/Floating"=opaque chamber on water surface
  6. Measurement Method: "Picarro" and "LGR "= Cavity ring-down spectroscopy instruments that measure CO2 and CH4 in the field; "EGM" = Infrared gas analyzer that measures CO2 in the field; "CH4 serums" = gas collection in serum bottles for laboratory analysis of CH4 using a gas chromatograph
  7. Water temp: Near-surface temperature of standing water [°C]
  8. Air temperature: Air temperature during measurement [°C]
  9. CH4 Flux: Methane flux (positive number is to the atmosphere; negative number is from the atmosphere) [mmol CH4 m-2 hr-1]
  10. CO2 Flux, Gross: Carbon dioxide flux using a dark chamber (positive number is to the atmosphere; negative number is from the atmosphere) [mmol CO2 m-2 hr-1]
  11. CO2 Flux, Net: Carbon dioxide flux using a light chamber (positive number is to the atmosphere; negative number is from the atmosphere) [mmol CO2 m-2 hr-1]
  12. Active Layer depth: Depth to frozen soil (from surface) [cm]
  13. Water Height: Height of water (positive number is height above soil/sediment surface; negative number is depth below soili/sediment surface) [cm]
  14. Soil temp 5cm: Soil temperature 5 cm below the ground surface [°C]
