Abstract

This data set reports the results of a field study investigating the effect of temperature on organic-matter decomposition in the West Fork of Walker Branch, a headwater stream on the Oak Ridge Reservation in east Tennessee. The goal of this project was to evaluate the effect of temperature on organic-matter decomposition in a stream ecosystem to better understand how carbon dynamics across terrestrial-aquatic carbon interfaces may change with warming. The West Fork is a spring-fed headwater stream and the spring inputs create a natural longitudinal temperature gradient. In winter, the upstream sites near the springs are warmer due to the spring input. In summer, the temperature gradient reverses and the upstream sites are cooler. One experiment examined the decomposition of senesced leaves from 3 tree species (red maple [Acer rubrum], tulip poplar [Liriodendron tulipifera], and white oak [Quercus alba]) along the temperature gradient in winter (December 2011 - March 2012). The second experiment examined the breakdown of cotton strips, a substrate of consistent quality (95% cellulose), along the temperature gradient with approximately month-long incubations over ~2 years (August 2011 to October 2013). This dataset contains six data files in comma separate (*.csv) format.

Walker Branch Watershed: Weekly Stream Water Chemistry

Dataset Mulholland, P.J. ; Griffiths, N.A.

This data set reports weekly stream water chemistry in the West and East Forks of Walker Branch Watershed (WBW). The long-term Walker Branch stream chemistry monitoring is intended to provide data on watershed output of chemicals via streamflow and long-term changes in stream chemical composition. This data set contains two data files of stream water chemistry collected at weekly time intervals from 1989 through 2013. Weekly sampling of stream water started in 1989 in the West Fork and in 1995 in the East Fork. Measured parameters include water level at the weir and stream discharge, water temperature, specific conductivity, pH,more »« less
Walker Branch Watershed: Daily Stream Metabolism and Organic Carbon Spiraling Metrics in the West Fork of Walker Branch, Tennessee, USA, 2004-2010

Dataset Roberts, Brian ; Pilla, Rachel ; Griffiths, Natalie

This dataset contains daily metabolism estimates of gross primary production (GPP), ecosystem respiration (ER), and net ecosystem production (NEP), in addition to organic carbon spiraling length (SOC) and mineralization velocity (VfOC) estimates at the West Fork of Walker Branch, a small headwater stream, in the Walker Branch Watershed, Tennessee, USA. Observations were made from 2004-2010 (2004-01-01 to 2010-12-31). These data were generated to assess seasonal and interannual variability in metabolism and organic carbon spiraling and to explore potential driver variables, as analyses of intra- and interannual variability in metabolism and organic carbon spiraling are currently limited, leaving knowledge gaps inmore »« less
Walker Branch Watershed: Daily Climate and Soil Temperature Data

Dataset Mulholland, P.J. ; Griffiths, N.A.

This data set reports daily climate and soil temperature data for Walker Branch Watershed. As part of the long-term Walker Branch project, daily climate and soil temperature data were collected using instruments on a meteorological tower located in an upper slope of the watershed. This data set contains one data file of daily climate and soil temperature data from 1993 through 2010. Measurement collection began in 1993 as part of the Throughfall Displacement Experiment (TDE) in the control (ambient) plot. Measurements include daily integrated values for above canopy incident photosynthetically active radiation, above canopy incident total radiation, air temperature, relativemore »« less

Dataset Mulholland, P.J. ; Griffiths, N.A.

This data set reports 15-minute and daily stream discharge, and annual runoff for the West and East Forks draining Walker Branch Watershed (WBW). The long-term Walker Branch Hydrology Monitoring project was intended to document changes in the water balance (precipitation inputs, stream discharge outputs) for the WBW over time. This data set contains three data files of stream discharge (L/s) for 15-minute and daily intervals, and annual runoff (cm). The daily and annual datasets began in 1969 in both East and West Forks, while the 15-minute datasets began in 1994 in both Forks. Data were collected through 2014 for themore »« less
