Laboratory mesocosm data measuring the impact of bioturbation frequency on greenhouse gas emissions from reservoir sediments

Inland aquatic systems are major global contributors to the atmospheric carbon budget through greenhouse gas (GHG) emissions, although the amount and form of carbon released varies widely across and within systems. Bioturbation of aquatic sediments can impact biogeochemical conditions and physically release sediment-bound bubbles containing GHGs, but variation in the frequency of such disturbance may modify the rate and composition of resulting GHG emissions. We hypothesized that an intermediate bioturbation frequency would result in the greatest methane (CH4) releases due to mechanical release of trapped bubbles, while frequent disturbance would result in greater diffusive carbon dioxide (CO2) releases relative to CH4, due to increased aeration of the sediment. We tested this bioturbation frequency hypothesis using laboratory mesocosms containing homogenized reservoir sediment. We used mechanical disturbance to simulate bioturbation at 3, 7, 14, or 21-day intervals; a control treatment was undisturbed for the duration of the experiment. We measured GHG emission (ebullition and diffusion) rates. An intermediate frequency of disturbance (7 days) produced the highest total GHG emission rate, while the most frequent disturbance interval (3 days) and least frequent interval (0 days) reduced overall GHG emissions relative to weekly disturbance by 24% and 15%, respectively. These patterns were primarily driven by differences in CH4 ebullition. Contrary to our hypothesis, there was no relationship between disturbance frequency and diffusive CO2 emissions. For all disturbance treatments, the majority of ebullition occurred during disturbance events, suggesting mechanical release of entrapped bubbles is an important emission mechanism. The frequency of disturbance has variable effects on GHG emissions and may explain conflicting results in prior studies of bioturbation. Our study provides insight into bioturbation as a driver of within-system variation in GHG emissions and h

Seed bank densities across an environmental gradient from the Coweeta Hydrologic Laboratory from 1995 to 1998

We determined the distribution of seed bank densities of woody perennial species across 5 permanent vegetation plots. We found that the distribution of seeds in the soil was determined by the spatial location of parent trees at all sites, but that absolute densities varied significantly between plots.

Monthly data from Climate Station 1 (CS01), Coweeta Hydrologic Laboratory, Otto, NC, 1934-2018

This dataset contains base-line climatic information for the main climate station (CS01) at Coweeta Hydrologic Laboratory in Macon County, North Carolina, USA. The station is operated by the Southern Research Station, Forest Service, USDA. CS01 is also a cooperative station with the National Weather Service. Since May 1963 it has been located in a grassy field NW of the junction of Ball Creek and Shope Fork of Coweeta Creek. Previously CS01 was located about 100m SW of its current location. The current elevation is 685.5m (2249ft) at latitude 35-3-37.21N and longitude 83-25-49.02W. During the 1940s, forest re-growth was tolerated up to 150 feet from the station. In August 1949, the larger opening was reestablished. The high elevation precipitation gage is located in a forest opening on Mooney Gap at elevation 1362.6m (4475ft).

Watershed 27 or Hard Luck Creek is a north-northeast facing reference catchment encompassing 96.5 acres (39ha) or .15080 sq. miles. The elevation ranges from 3380ft (1061m) at the weir to 4770ft (1454m). The average land slope is 54.7%, and the average channel slope is 33.2%. The channel is a total of 3894ft (1187m) long.

Predatory impact of benthic fishes in an Appalachian stream at the Coweeta Hydrologic Laboratory in 1998

Streams are characterized by high degrees of patchiness that could influence the role of predators in these systems. Here we assess the impact of predatory benthic fishes on benthic macroinvertebrate density, biomass, and community structure at the patch scale in a fourth order stream in the southern Appalachians in 1998. We conducted this experiment from July to September 1998 in Ball Creek, a fourth order stream at the USDA Forest Service’s Coweeta Hydrological Laboratory, Otto, North Carolina. We tested the role of predation in two different patch types: patches inhabited by adult mottled sculpin (Cottus bairdi ) and random patches. We placed 30 basket pairs (one open to fish predation, and one from which fish predators were excluded) in the streambed at each patch type. We also tested for potential basket effects by setting up a basket control area.
