Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Denitrification is potentially a significant process of soil nitrogen removal from the Hubbard Brook Experimental Forest (HBEF) ecosystem. Its magnitude and variation can depend on physical conditions within the soil, particularly oxygen concentration, moisture, and temperature. This dataset contains continuous measurement of soil oxygen, moisture and temperature near the biogeochemical reference Watershed 6 at (HBEF). Data were collected from Campbell Scientific CR1000 dataloggers with sensors installed at 3 depths, each at a soil horizon transition and at an hourly time interval. The timeframe of the dataset is 1 year starting in July 2018 and ending in July 2019. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Methods and protocols used in the collection of this data package

Description:

In July 2018, three Campbell Scientific dataloggers were installed at sites within the area west of the biogeochemical reference Watershed 6. Each site was located within a designated forest type and elevation. The low elevation (600m) low hardwoods, the middle elevation (790m) high hardwoods, and the highest elevation (800m) spruce-fir. For each datalogger, soil oxygen, moisture, and temperature were measured at three soil depths corresponding to soil horizons at the site. Sensors at low hardwoods and high hardwoods were installed at 10, 20, and 45cm and sensors at the spruce-fir were installed at 10, 30, and 45cm. Soil oxygen was measured as the relative percentage of oxygen gas (RelativePercentOxygen) in the air. Soil moisture was measured as volumetric water content (VWC) (CubicCentimetersPerCubicCentimeters). Soil temperature was measured in degrees Celsius (DegreesCelsius). The datalogger program took hourly measurements of each variable and the continuous measurement period continued from July 14, 2018 to July 25, 2019. Some missing data occurred in the spruce-fir elevation site for the VWC and temperature sensors at 10cm depth. VWC data were gap-filled using linear regression. The linear regression was calculated for a relationship between the sensor data at the 10cm depth and the additional sensor data at other depths. The resulting equation for this relationship was used to calculate missing data. The mean of each relationship was taken and used to replace missing data and results were evaluated graphically to determine outliers. For missing soil temperature data, an additional temperature sensor on the oxygen sensor at the same depth was used as replacement.
