This dataset represents 25 parallel longitudinal profiles that were extracted from terrestrial lidar point clouds taken during six survey periods. The six lidar surveys were conducted between 7 October 2010 and 8 October 2013. Over that time a colluvial hollow eroded into a fluvial channel. The longitudinal profiles show the topography of the colluvial hollow for each survey period. The width of the original colluvial hollow was approximately 1.25 m, and a longitudinal profile was extracted every 5 cm for the entire length of the hollow, resulting in 25 parallel longitudinal profiles. These data can be used to observe the transition of the colluvial hollow to a fluvial channel and furthermore they show the development...

The West Hills of Portland, in the southern Tualatin Mountains, trend northwest along the west side of Portland, Oregon. These silt-mantled mountains receive significant wet-season precipitation and are prone to sliding during wet conditions, occasionally resulting in significant property damage or casualties. In an effort to develop a baseline for interpretive analysis of the groundwater response to rainfall, an automated monitoring system was installed in 2006 to measure rainfall, pore-water pressure, soil suction, soil-water potential, and volumetric water content at 15-minute intervals. The data show a cyclical pattern of groundwater and moisture content levels—wet from October to May and dry between June and...
This dataset is the largest global dataset to date of soil respiration, moisture, and temperature measurements, totaling >3800 observations representing 27 temperature manipulation studies, spanning nine biomes and nearly two decades of warming experiments. Data for this study were obtained from a combination of unpublished data and published literature values. We find that although warming increases soil respiration rates, there is limited evidence for a shifting respiration response with experimental warming. We also note a universal decline in the temperature sensitivity of respiration at soil temperatures >25°C. This dataset includes 3817 observations, from control (n=1812), first (i.e., lowest or sole) level...

This dataset contains field measurements of vegetation from the (1) Adirondack Sugar Maple Project (ASM), and (2) Buck Creek North and Buck Creek South Watersheds. The ASM data, collected in 2009 in 20 Adirondack watersheds (2 or 3 0.10 ha plots per watershed), are comprised of general plot characteristics, tree species identification and diameter at breast height (DBH) for all trees greater than 10 cm DBH, canopy position and health ratings, common and scientific names, and species identification and counts for saplings and seedlings. In Buck Creek North Tributary Watershed and Buck Creek South Tributary Watershed, near Inlet, New York, all trees greater than 5 cm DBH were identified in 15 circular plots (245 square...

This dataset contains data supporting the paper: DeCrappeo, N.M., DeLorenze, E.J., Giguere, A.T., Pyke, D.A., and Bottomley, P.J. Fungal and bacterial contributions to nitrogen cycling in cheatgrass-invaded and uninvaded native sagebrush soils of the western USA (accepted at the journal Plant and Soil). The purpose of the study was to evaluate the relative contributions of soil bacteria and fungi to inorganic nitrogen (N) cycling in sagebrush and cheatgrass-invaded soils using a 15N isotope dilution experiment. Soils were collected from sagebrush and cheatgrass rhizospheres at six paired sites in southwest Idaho and southeast Oregon. In order to partition the contribution of each microbial group to N cycling, soils...

Monitoring shoreline change is of interest in many coastal areas because it enables quantification of land loss over time. Evolution of shoreline position is determined by the balance between erosion and accretion along the coast. In the case of salt marshes, erosion along the water boundary causes a loss of ecosystem services, such as habitat provision, carbon storage, and wave attenuation. In terms of vulnerability, higher shoreline erosion rates indicate higher vulnerability. This dataset displays shoreline change rates at the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA. Shoreline change rates are based on...

This dataset contains measurements of chemical concentrations of forest soil samples and associated site measurements collected in the Adirondack Ecoregion of New York State. Data are presented in four groups (tabs) in an Microsoft EXCEL 2013 spreadsheet (and comma-delimited CSV files): (1) Adirondack Sugar Maple Project (ASM), (2) Buck Creek North Watershed, (3) Buck Creek South Watershed, and (4) Western Adirondack Stream Survey (WASS) soil sampling. The ASM data were all collected in 2009 and the WASS data were all collected in 2004. The Buck Creek North Tributary Watershed was sampled in 1997 and repeated at the same plot locations in 2009/10. The Buck Creek South Tributary Watershed was sampled in 1998 and...

Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. While drylands as a whole are expected to increase in distribution and aridity in coming decades, temperature and precipitation forecasts vary by latitude and geographic region suggesting different trajectories for tropical, subtropical, and temperate drylands. Uncertainty in the future of tropical and subtropical drylands is well constrained, whereas soil moisture and ecological droughts, which drive vegetation productivity and composition, remain poorly understood in temperate drylands. Here we show that, over the 21st century, temperate drylands may contract by a third, primarily converting to subtropical drylands,...

Concentrations of tetrachloroethylene (PCE) in interpolated soil surface boundary points at the Vienna Wells Site: Maries County, Missouri. This boundary is composed of points with an assumed PCE concentration of 11 micrograms per kilogram (detection limit) and was used with the soil sample dataset (doi: 10.5066/F71835D8) to create an interpolated surface. These data support the following publication: Wilson, J.L., Samaranayake, V.A., Limmer, M.A., Schumacher, J.G., Burken, J.G., 2017, Contaminant Gradients in Trees: Directional Tree Coring Reveals Boundaries of Soil and Soil-Gas Contamination with Potential Applications in Vapor Intrusion Assessment: Environmental Science and Technology, Just Accepted Manuscript....

Concentrations of tetrachloroethylene (PCE) in points from interpolated tetrachloroethylene soil data gridded at a 1-m interval at the Vienna Wells site, Vienna, Missouri, 2012-2015. These data were extracted at 1-meter intervals from interpolating published soil data (doi: https://doi.org/10.5066/F71835D8), which was created using the inverse-distance weighting method at a 1-meter interval, the mean PCE concentration at each location, a power of 2, and minimum and maximum neighbor search of 10 and 15. These data support the following publication: Wilson, J.L., Samaranayake, V.A., Limmer, M.A., Schumacher, J.G., Burken, J.G., 2017, Contaminant Gradients in Trees: Directional Tree Coring Reveals Boundaries of Soil...

A Gust erosion chamber was used to apply horizontal shear stress to sediment cores obtained at selected locations within the Yolo Bypass near Sacramento, California. The locations correspond to different land uses; two cores were taken at each site. The shear stress was increased in stepwise fashion, and turbidity of the effluent monitored. From this, two quantities are calculated: 1) critical shear stress required to initiate erosion, and 2) soil mass eroded per square meter at an applied shear stress of 0.4 Pa. So for each core we have a date, land use or site, core number, latitude, longitude, critical shear stress, and eroded mass at tau = 0.4 Pa.
