Sedimentary data from the lower Pearl River, Louisiana, USA

Scientists from the U. S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center investigated the sedimentary and geochemical properties of the lower reaches of the Pearl River in eastern Louisiana by collecting estuarine, riverine and marsh sediments. This was done in order to increase understanding of the region's environmental history, quantify the deposition associated with Hurricane Katrina, identify the subsequent changes in the deposited sediments and assess the effects of this deposition on marsh sustainability. To this end, the group obtained long sediment cores, shovel-dug sediment slabs and marsh and riverine channel/estuarine surface samples from  a north-south transect along the river edge from the low-salinity bottomland hardwood forest through Lake Borgne, and a west-east transect near the coast, during field work conducted in September 2015.

Chesapeake Bay Nontidal Network 1985-2017: WRTDS output data

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring Network (RIM) stations for the period 1985 through 2017. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the RIM watersheds.

Dissolved organic carbon and nitrogen release from boreal Holocene permafrost and seasonally frozen soils of Alaska

Permafrost (perennially frozen) and active-layer (seasonally thawed) soils varying in soil carbon (C) and nitrogen (N) content and radiocarbon age were collected from three sites in interior Alaska to determine potential release of dissolved organic carbon (DOC), total dissolved N (TDN), dissolved organic nitrogen (DON), and dissolved inorganic nitrogen (DIN) upon thaw. Soil cores were cut into 15 cm thick sections, and deep active-layer (15-30 cm above the permafrost boundary) and shallow permafrost (15-30 cm below the permafrost boundary) sections were thawed and leached with deionized water. Soil leachates were analyzed for DOC, TDN, nitrate (NO3-), and ammonium (NH4+) concentrations, dissolved organic matter optical properties, and DOC biodegradability. Soils were analyzed for moisture content, bulk density, C, N, and radiocarbon content. Releases of dissolved carbon and nitrogen from soils are expressed as yields, with the units of milligrams (DOC, TDN, DIN, DON) per gram dry soil.

Chesapeake Bay River Input Monitoring Network 1985-2017: Short- and long-term trends

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring Network (RIM) stations for the period 1985 through 2017. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the RIM watersheds.  To determine the trend in loads, the annual load results are flow normalized to integrate out the year-to-year variability in river discharge.  The trend in load is derived from the flow-normalized load timeseries and represents the change in load resulting from changes in sources, delays associated with storage or transport of historical inputs, and (or) implemented management actions.

Chesapeake Bay River Input Monitoring Network 1985-2017: Average annual yields

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring Network (RIM) stations for the period 1985 through 2017. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  Yields (represents the mass of constituent transported from a unit area of a given watershed) are used to compare the export loads from one basin to another.  Yield results are obtained by dividing the annual load (pounds) of a given constituent by the respective watershed area (acres) from which the constituent was transported.  Yield results presented represent the average annual per-acre loads of nitrogen, phosphorus, and suspended sediment exported from each of the Chesapeake Bay River Input Monitoring stations for two possible time periods:  2008-2017 (10 year average yield) and 2013-2017 (5 year average yield).

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Water Balance

Flow interaction between Willow Creek Lake and groundwater was calculated from a lake water balance (Healy and others, 2007) in which all of the other flow components were either measured or estimated between 2012 and 2014 (as described in Rus and others, 2018) and the interaction was the residual term.  Inflow terms consisted of streamflow at three sites (Foster, NT, and ST) as well as the direct precipitation onto the lake.  Measured outflow terms consisted of the streamflow at the outflow site and the direct evaporation from the lake.  Increases in lake storage had the same effect on the water balance as an outflow.  All components of the water balance were tabulated on a daily basis and converted to units of acre-feet per day.  As written, this water balance considers groundwater interaction as an outflow, but this interaction can actually occur as an inflow or an outflow.  Positive values of groundwater represent flow into the groundwater away from the lake, and negative values represents a gain of water to the lake from groundwater.

In situ geochemical data related to the gold-quartz veins of Grass Valley, California, 2014-2015

In situ geochemical data were obtained for pyrite crystals and native gold from two distinct vein sets in the Grass Valley gold district, California. Samples of the N-S (north-south-trending) veins were collected underground at the Empire Mine State Historic Park and samples of the E-W (east-west-trending) veins were collected from drill core provided by the Idaho-Maryland Mining Corporation in 2008. These geochemical data were analyzed to better understand paragenesis of quartz veins in orogenic gold deposits. Data includes electron probe microanalysis (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) chemistry and LA-ICP-MS sulfur isotope values for pyrite crystals, and EPMA geochemistry of native gold grains found within the orogenic gold veins. The geochemical results presented in this data release were analyzed at the U.S. Geological Survey in Denver, Colorado.  
Electron probe microanalyses were performed using a JEOL 8900 electron microprobe with five wavelength dispersive X-ray spectrometers. Operating conditions included a beam current of 100 nano-ampere (nA) measured on the Faraday cup, a focused electron beam, and an accelerating voltage of 20 kiloelectron-volt(keV).  
Minor and trace element geochemistry was determined by LA-ICP-MS using a Photon Machines Analyte (193-nanometer (nm) excimer) coupled to a PerkinElmer DRC-e ICP-MS using a spot size of 25 micrometers (µm).  
In situ sulfur isotope data was collected using a Nu Instruments high-resolution MC-ICP-MS via a 193-nm wavelength GS excimer laser ablation system with spot sizes varying from approximately 25-55 µm.

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Streamflow

Streamflow was measured at the three largest inflows (the Foster, NT, and ST sites) of Willow Creek Lake and at the outflow of the lake. Flow data were typically available at a 15-minute frequency, but generally were summarized as daily means. Flow data for the Foster, NT, and outflow sites were provided by the Nebraska Department of Natural Resources (NDNR) and were estimated using stage-flow relations applied to measured stage following protocols described by Kennedy (1983).  Flow at the ST site was measured by the U.S. Geological Survey using an indirect rating curve with water levels monitored continuously by a submersible pressure transducer and periodic streamflow measurements collected using a Parshall flume (Kilpatrick and Schneider, 1983).  Gap-filling techniques were applied to complete the datasets at the NT and ST sites.  Adjustments were made to the Foster and outflow site streamflow values to account for hydrologic changes that were observed between the measurement sites and the lake.  Additional information is provided in Rus and others (2018)

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Sediment Nutrients

The retention or release of nutrients into the water column from sediment, also known as internal loading, is another source of nutrients to the lake water column.  Sediment cores collected from Willow Creek Lake in September 2013 and June 2014 were incubated for 7 days to assess potential for sediment to produce or consume water column phosphorus under aerobic (oxic) and anaerobic (anoxic) conditions using techniques similar to Penn and others (2000); the oxic conditions served as a control and the anoxic conditions represented typical lake sediment environments.   
Phosphate as phosphorus and total dissolved phosphorus release rates (milligrams phosphorus per square meter per day) were estimated by dividing the change in phosphate concentration by the water residence time in the core chamber (core water volume divided by the pump flow rate) and correcting for the sediment area in each core. Cumulative phosphate as phosphorus and total dissolved phosphorus fluxes were estimated by summing the release rates through time over the course of the experimental incubation.

Marsh Island Hydrologic Restoration (TV-14): 2016 land-water classification

The Louisiana State Legislature created Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Marsh Island Hydrologic Restoration (TV-14) project for 2016. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration efforts, a land-water classification is performed on specific CWPPRA sites to help assess landscape changes.

Inputs and Selected Predictions of a Differential Spatially Referenced Regression Model for 20-year Changes in Total Nitrogen in the Chesapeake Bay Watershed

The core equations of the SPARROW model (Schwarz and others, 2006) were implemented in differential form using the R programming language (R Core Team, 2017), as the basis of a tool for empirically relating a regional pattern of changes in constituent flux, over a multi-year period, to spatially referenced changes in explanatory variables over the same period. A pilot implementation was developed to explore factors influencing changes in flow-normalized flux of total nitrogen (TN) over the period 1990-2010 at 43 sites in the non-tidal Chesapeake Bay watershed. Model inputs, outputs, and code are included in this data release, and are described below.
