Lake Pertusillo reservoir induced seismicity catalog (Southern Italy)

We present a detailed analysis of the small magnitude (ML<3) Reservoir Induced Seismicity associated with the Pertusillo water reservoir located in the high seismic hazard zone of Val d’Agri (Southern Italy).  We apply template-matching detection to a 13-month-long dense passive survey, obtaining a final high-precision double-difference catalog of 5,068 earthquakes (-0.7<ML<2.6, MC=0.2).  The original template dataset is composed of 408 hand-picked earthquakes, recorded during a 13-month-long (2005-2006) passive survey, at a dense network of 46 seismic stations (the average receiver spacing is 5 km) composed by: 22 temporary 3C continuously-recording stations of the temporary experiment described in Valoroso et al., [2009], plus 24 permanent INGV and ENI (the local oil company) stations, and accurately located in a 3D high-resolution VP and VP/VS velocity model [Improta et al., 2017].  The attached file is a plain text with a space as separator.  Here below the header is explained. ID: the unique event identifier LAT: hypocenter latitude expressed in degrees  LONG: hypocenter longitude east of Greenwich, expressed in degrees DEPTH: hypocenter depth expressed in km  OTIME: date of the origin time in the format YYYY-MM-DD[T]hh:mm:ss.msec ML: magnitude (pure number)

Dataset from University of Idaho 2004, master's thesis [Littoral ecology of epilithic algae in the Rocky Reach Pool, Mid-Columbia River (Washington State) - The effects of reservoir fluctuations.]

(Abstract from thesis) Epilithic algae, water column physical/chemical properties, and sediments were examined in the impounded Mid-Columbia River including the Rocky Reach Reservoir. Primary objectives included determination of the effects reservoir drawdown has on epilithic algae and potential nutrient enrichment via sediment. Epilithic algae were analyzed by pigment concentration, gravimetrically, and species composition. Reservoir elevation fluctuated at higher rates at tailrace sites (0.41-0.25 m/hr) compared to the forebay site (0.06-0.08 m/hr). Littoral exposure times were also greater at tailrace sites (mean of 8 hrs compared to 0 hr at the forebay site). Mean epilithic algae monochromatic chlorophyll a over all sampling periods at mainstem sites was 76.7 ± 4.8 mg/m2 (95 % C.I.). Epilithic algae monochromatic chlorophyll a in the zone of water fluctuation (0-1 m) was less at Wells tailrace (38.8 mg/m2) compared to Rocky Reach forebay (141.3 mg/m2) during summer, 2000 and 2001. Mean epilithic biofilm ash-free oven-dry weight over all sampling periods at mainstem sites was 25.6 ± 1.5 g/m2 (95 % C.I.). Mean autotrophic index across all mainstem locations was 439 indicating a large heterotrophic component within the epilithic biofilms. Epilithic algae communities were dominated by diatoms (50.2 %) and cyanobacteria (35.9 %), with some green algae (13.8 %). Canonical correlation analysis indicated that temperature, depth, site, and the water elevation change rate were important controllers of epilithic algae chlorophyll pigments. Mean textural characteristics of dredged sediment were 51.1 % sand, 43.2 % silt, and 5.7 % clay. Mean organic matter content in this sediment was 4.1 %. The mean seston sedimentation rate across mainstem locations was 11.3 g m-2 d-1 and organic matter comprised 14.7 % of the material collected from the water column.

Bathymetry and watershed area for Falling Creek Reservoir, Beaverdam Reservoir, and Carvins Cove Reservoir

This data package includes bathymetric data and watershed delineations for Falling Creek (FCR), Beaverdam (BVR), and Carvins Cove (CCR) Reservoirs, all located near Roanoke, VA, USA. Bathymetric data were collected using an Acoustic Doppler Current Profiler (ADCP) and processed using WinRiver II and ArcGIS. Water level can vary in these reservoirs; at the time of ADCP measurement, maximum depth was ~9.3 m in FCR, ~13.5 m in BVR, and ~23 m in CCR. Bathymetric data are presented in two forms: (1) as hypsometric summaries of surface area and volume for 0.3-1.0 m depth intervals (for all three reservoirs) and (2) as spatially-explicit shapefiles (BVR and FCR) and triangular irregular networks (TIN) files (FCR and CCR). Watershed areas are included as shapefiles for each reservoir.

Total organic carbon, total nitrogen, and iron-bound organic carbon in surficial sediment and settling particulate material from Falling Creek and Beaverdam Reservoirs in 2019 and 2021

This dataset includes measurements of sediment properties (total organic carbon, total nitrogen, and iron-bound organic carbon) in surficial sediment and sedimenting material from two reservoirs: Falling Creek and Beaverdam Reservoirs, both located in Vinton, VA, USA. To measure surficial sediment properties, sediment cores were collected at the deepest site in each reservoir using a gravity corer, and the top 1 cm was frozen then lyophilized. Sediment cores were collected approximately once per month in both reservoirs throughout the stratified period (May–November) in 2019 and 2021, though sampling frequency and duration varied by reservoir and year. Sedimenting material was sampled using sediment traps suspended approximately 1 m above the sediment in both reservoirs. Iron-bound organic carbon was measured using the citrate-bicarbonate-dithionite method, and we used a CN analyzer (Elementar VarioMax, Ronkonkoma, NY, USA) to determine the amount of OC per unit mass of sediment.

Small reservoir grab sample data, Parker, Ipswich, Lamprey, and Oyster River Watersheds, 2015 - 2020

This dataset contains water quality data from the inputs and outputs of eight reservoirs located in southeastern New Hampshire and northeastern Massachusetts. Samples were filtered in the field using Whatman GF/F filters with a nominal pore size of 0.7 µm and stored on ice until returned to the lab where they were frozen until analysis. Samples were analyzed for anions (NO3-, Cl-, SO4-, Br-) via ion chromatography on a Dionex Ion Chromatograph; NH4+ using a colorimetric method on a SmartChem Chemistry Analyzer; and total dissolved nitrogen (TDN) and dissolved organic carbon (DOC) via high-temperature oxidation on a Shimadzu TOC-V. DON was calculated as the difference between TDN and DIN (NO3- + NH4+). Samples correspond with individual sample names. Site (n = 8) indicate which reservoir each sample belongs to. Location indicates whether a sample was collected at the outflow or inflow ("UP", for reservoirs with one inflow) or "UP_1", "UP_2", or "UP_3" for sites with up to three inflows. CArea.km2 is the upstream drainage area estimated from the reservoir outflow while SArea.km2 is the surface area of each reservoir calculated via NHD+ polygons in GIS software. Temp.C is water temperature at the reservoir outflow on the day of sample collection while Discharge.m3s is the daily discharge scaled to the reservoir outflow from the nearest USGS gaging station. DIN.mgL, DON.mgL, and TDN.mgL are concentrations of dissolved inorganic nitrogen, dissolved organic nitrogen, and total dissolved nitrogen, respectively, in mg/L.

A Comparison of Recreational and Survey-Grade Side-Scan Sonar Systems in Mapping Reservoir Fish Habitat in 3 Southwest Ohio Reservoirs

Littoral zone aquatic habitat is thought to play an important driver of aquatic organism population dynamics, but historically has been difficult to obtain at the whole waterbody scale because it is costly and time-consuming to collect with traditional aquatic habitat sampling methods. Here we used side-scan sonar to quantification of habitat features over large areas using two levels of equipment: recreational (consumer-grade) and professional (survey-grade). Our goal was to compare performance of the different side-scan sonars by analyzing their ability to map shoreline habitat features (wood, vegetation, and substrate) in three southwest Ohio reservoirs that contain the range of habitat features of interest to fisheries biologists. We used a low-cost Lowrance Active Imaging 3-in-1 system (≈$2,000 USD) recreational sonar and an EdgeTech 6205 system (≈$150,000 USD) survey-grade sonar to collect imagery along the shoreline of three reservoirs in Ohio. Using imagery from each system, We manually delineated patches of submerged woody debris, standing timber, aquatic vegetation, and benthic substrate in GIS. We also compared the size of uniquely identifiable submerged wood from paired imagery to understand potential biases between the systems.

Methane ebullition and diffusion rates, turbulence, water temperature, and water depth data from Falling Creek Reservoir (Virginia, USA) in the ice-free period during 2016-2019

This dataset includes weekly and subweekly methane ebullition and diffusion rates collected from March through November in 2016, 2017, 2018, and 2019 in Falling Creek Reservoir (FCR), a drinking water reservoir owned and managed by the Western Virginia Water Authority and located in Vinton, Virginia, USA. In 2016, ebullition rates were measured at four near-shore sites along a longitudinal gradient in FCR that included four replicate locations within each site, for a total of 16 sites in the reservoir. In 2017, methane emission rates and five different potential environmental driver variables (water temperature, wind speed, pressure, turbulence, primary production) were measured at five longitudinal transects that included four replicate sites per transect, for a total of 20 sites in the reservoir. In 2018, ebullition was measured at the same five longitudinal transects but with two replicate sites per transect, for a total of 10 sites. In 2019, ebullition was only measured at the furthest upstream transect monitored in 2017-2018, with four replicate sites within that transect. The dataset consists of four tables: 1) weekly methane ebullition and diffusion rates and the water depths at each of the 24 unique monitoring sites; 2) 10-minute resolution sediment-water interface and surface water temperatures from 16 sites in 2017; 3) weekly sediment-water interface and surface turbulence at the four transects in 2017; and 4) geographical coordinates of each of the 24 sites in the reservoir.

Half-hourly gap-filled Northern Hemisphere lake and reservoir carbon flux and micrometeorology, 2006 - 2015

This archive accompanies the manuscript New insights into diel to interannual variation in carbon emissions from lakes and reservoirs We synthesize 171 site-months (and 3,832 site-hours) of high-frequency flux measurements to quantify the magnitudes and temporal variability of direct CO2 fluxes from 13 lakes and reservoirs in the Northern Hemisphere (NH). Constraining short- and long-term variability is necessary to improve detection of temporal changes of CO2 fluxes in response to natural and anthropogenic drivers. These data were collected based on a workshop and open call for eddy covariance observations over lakes organized by Ankur Desai (UW-Madison), Timo Vesala (U Helsinki), and Malgorzata Golub (DKIT).

Phosphorus Content of Belwood Reservoir Sediment Core

On February 14, 2018, four sediment cores were obtained from Belwood Lake, an approximately 7-km2 reservoir in the upper Grand River Watershed that was created in 1941 as a result of dam construction.Of these four, one core, , 8.7 cm internal  diameter and 47 cm long, was selected for sediment core dating and laboratory analysis. Cores were collected using a Glew hammer-driven gravity corer fitted with a lucite tube and were subsequently transported to the lab, where they were sectioned at 0.5-cm intervals. Sediment samples were sealed in plastic bags and refrigerated at 4℃ until undergoing further analysis. One of the four cores collected (47 cm long), was selected for sediment core dating and laboratory analysis. In the laboratory, sequential loss-on-ignition (LOI) analysis was performed using ~0.5-g subsamples of wet sediment from each core slice, as described previously, to obtain the organic matter and carbonate content. The sediment P content of core slices was determined by IC-OES (Thermo Scientific iCAP 6300) after digestion with potassium persulfate-sulfuric acid . A sediment core chronology was developed based on gamma ray spectrometric determination of 210Pb activity at contiguous 0.5-cm intervals, using previously described methods.
