Plant and carbon data, snowmelt manipulation experiment, Rocky Mountain Biological Laboratory (RMBL), 2023
These data are from a 2023 snowmelt manipulation experiment in Vera Meadow at the Rocky Mountain Biological Laboratory. We experimentally advanced the snowmelt date in a montane meadow by approximately 12 days using black shade cloths and assessed the effect on plant and carbon dynamics. We measured net ecosystem exchange, gross primary productivity, and soil respiration using a Li-COR 7500 five times biweekly from June to August, plant community composition using the pin-drop method five times biweekly from June to August, and root biomass nine times using bulk soil cores. Using drone imagery, we measured the Normalized Difference Vegetation Index (NDVI). This data package is completed.
Road-deposited sediment wash-off experiments on a large-scale laboratory
<p><span>This dataset includes raw and processed data from a series of large-scale laboratory tests that were conducted to assess and study the wash-off process of RDS (Road deposited sediments) considering variations in rainfall intensity, for two scenarios: 30 mm/h and 50 mm/h; and modifying RDS loads applied on BLOCK for three scenarios: 100 g/m<sup>2</sup>, 150 g/m<sup>2</sup>, 200 g/m<sup>2</sup>. First, the hydraulic was detailly characterized including rainfall intensity maps, water flows, surface water depths and surface water velocities for both rainfall intensities tested. A synthetic granulometric of RDS was homogeneously distributed on the physical model surface and then washed-off by the simulated rainfall. A total of 31 water samples were collected at the manhole discharge per each experiment. Total RDS mass that remain on the surface and inside the gully was collected by a wet vacuum after the rainfall event. A mass balance considering the initial RDS applied and the total RDS recollected in the three samples locations, was calculated. TUR (Turbidity), EC (Conductivity), TS (Total Solids), TSS (Total suspended solids), TDS (Total dissolved solids), RDS mass by flow, and RDS mass flow variables were measured for the RDS samples recollected in the Manhole discharge. The behaviour of each RDS fraction was also analysed through laser diffraction (</span>Beckman Coulter LS 13 320, Aqueous Liquids Module<span>). This work is part of a Transnational Access developed by the Universidad Distrital Francisco José de Caldas (Colombia) and Universidade da Coruña (Spain) within the scope of Co-UDlabs project. Data may be used to increase knowledge on road-deposited sediment wash-off process, allowing also for calibrating, developing, and validating new and existing urban wash-off models.</span></p>
Laboratory experiments testing pH, alkalinity and particle impacts on Mn removal
Laboratory experiments were conducted to investigate impacts of pH, alkalinity, and presence of particles on Mn removal in freshwater. The dataset includes monitoring data from: 1) a 14-day experiment in Mn(II) solutions in nanopure water, 2) a 24-hour experiment in Mn(II) solutions in nanopure water, and 3) a 10-day experiment in water from two drinking water reservoirs. The 14-day pH and alkalinity laboratory experiment was conducted starting October 30, 2022 and included sample collection and pH monitoring on day 0, 1, 4, 7, 10, and 14. The 24-hour pH and alkalinity laboratory experiment was conducted starting February 20, 2023 and included sample collection and pH monitoring at 0, 1, 2, 6, 12, and 24 hours. The reservoir water laboratory experiment was conducted starting March 22, 2023 and included sample collection and pH monitoring on day 0, 1, 4, 7, and 10. This experiment tested Mn removal in water collected from the lower water column of Falling Creek Reservoir (FCR) and Carvins Cove Reservoir (CCR), located in Vinton, Virginia, USA and Roanoke, Virginia, USA respectively. Both reservoirs are owned and operated by the Western Virginia Water Authority and are managed as drinking-water sources for the city of Roanoke, VA, USA.

ENDGAME - Laboratory Experiment 2023-02-20 Exp. 001 - High Speed Camera data
<p>Shock-tube experiments in combination with high speed Schlieren shadow photography. </p> <p>The shocktube setup consists of a high-pressure reservoir connected with a cylindrical tube through a diaphragm pulse valve which allows a fast release of pressurized gas into the ambient pressure tube. The high-pressure reservoir is filled with compressed air at a given overpressure with respect to ambient pressure (up to 8 bar). The pipe was either empty (i.e. with air at ambient conditions) or filled with a given amount of fluids (water or viscous fluid) or small particles. We adopted pipes with different inner diameters (3 and 4 cm) and different lengths (30 and 80 cm). Images were collected at a frame rate of 30000 fps.</p> <p>When the valve is open, a jet flow is produced, with shock and acoustic waves propagating in the atmosphere, which become visible due to the high speed Schlieren shadow photography.</p>
