Annual estimates of suspended-sediment concentration and load to support trend analysis on the Mississippi River and Atchafalaya River, 1980-2015

This data release contains annual estimates of suspended-sediment concentration and load for the Mississippi River, St. Francisville site and the Atchafalaya River, Melville site from 1980-2015. Annual estimates and flow-normalized estimates were generated using the Weighted Regressions on Time, Season and Discharge (WRTDS) model. Input data for the model included suspended-sediment concentrations publicly available from the U.S. Geological Survey (USGS)'s National Water Information System (U.S. Geological Survey, 2016) and daily-mean streamflow estimates from the Army Corps of Engineers (2016) and USGS. These annual concentrations and loads are used to support trend analyses and provide estimates of sediment availability to the Gulf of Mexico. See companion publication for more details (Mize, S.V., Murphy, J.C., Diehl, T.H., and Demcheck, D.K., 2018, Suspended-sediment concentrations and loads in the lower Mississippi and Atchafalaya Rivers decreased by half between 1980 and 2015, Journal of Hydrology, In review).

Occurrence of natural nest cavities in montane ohia trees in Hawaii Volcanoes National Park

We quantified the availability of breeding habitat of the endangered Hawaiian Akepa (Loxops coccineus). The species is thought to nest excusively in natural cavities within mature ohia (Metrosideros polymorpha) trees but birds commonly occur in short stature trees that presumably do not have any natural cavities because of their polyploidal (many-branched) structure. To test this hypothesis we searched for cavities in trees where akepa forage and we measured diameter of each stem of each tree examined. The habitat is in montane areas of Hawaii Volcanoes National Park on Mauna Loa volcano.We surveyed 57 plots, 49 in montane woodland and 8 in closed-canopy forest. Six tree cavities were detected in the 214 sampled trees: five cavities were found in 38 trees sampled in closed canopy forest (8.9/ha) and only one cavity was found in 176 trees sampled in montane woodland (0.29/ha). Tree diameters in the forest ranged from 10 cm to 128 cm diameter at breast height (DBH), while those in the woodland were much smaller ranging from 10 cm to a maximum DBH of 54 cm. Most trees in the closed-canopy forest were monopodial (87%, mean number of stems per tree = 1.16, SE = 0.07) with only five of the 38 trees having multiple stems at DBH height. In contrast, most trees in the woodland were sympodial (61%, mean number of stems per tree = 2.11, SE = 0.11) where 108 of the 176 trees had multiple stems.

Sleeping Bear Dunes National Lakeshore qPCR Data. Collection Year: 2012

This environmental data-set consists of 56 sediment, 23 Cladophora and 23 water samples collected from beaches at Glen Haven, Good Harbor, Platte Bay and Esch road, located within The Sleeping Bear Dunes National Lakeshore, Leelanau and Benzie counties, Michigan.  The data-set includes matrix type, location, date, and the qPCR reported value for each sample collected. 
Sample Collection and Processing: 
Samples were collected from Glen Haven, Good Harbor, Platte road and Esch road beaches in Sleeping Bear Dunes National Lakeshore. Sites were situated a short distance from stream or river inputs (except Glen Haven), and all sites had been associated with previous botulism outbreak events.  Beach sediment, surface water, and Cladophora samples were collected from four sampling sites in SLBE from May to November 2012. At each site, surface water and beach sediment were collected from three locations, approximately 50 meters away from each other.  Where available, sloughed Cladophora samples were collected from the beach or floating near the beach within the same range that sediment and water collected. Where applicable, samples were collected in triplicate as described in Wijesinghe and others, 2015.  
DNA Extraction: 
Sediment samples were collected in triplicate, composited into one sample and homogenized.  Cladophora samples were collected as a single sample, in duplicate or in triplicate, composited into one sample and homogenized. Ten grams of sediment or Cladophora (wet weight) was used in each extraction per manufacture’s protocol (PowerMax® Soil DNA Isolation Kit. Mobio Laboratories, Carlsbad, CA).  Water samples were composited, and one hundred milliliters of surface water was filtered through a polycarbonate filter.  DNA was extracted per manufacture’s protocol, using a PowerSoil® DNA Isolation Kit used for water filters.

Cumulative Compaction of Subsurface Sediments (2017) in 13 Extensometers in the Chicot and Evangeline Aquifers in the Houston-Galveston Region, Texas.

The U.S. Geological Survey, in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District, produced a dataset through 2017 of compaction values in the Chicot and Evangeline aquifers in the Houston‐Galveston region, Texas. 
This dataset contains compaction values of subsurface sediments (mostly in the fine-grained silt and clay layers because little compaction occurs in sand layers) in the Chicot and Evangeline aquifers that were recorded continuously by using analog technology at the 13 extensometers at 11 sites that were either activated or installed between 1973 and 1980. At 2 of the 11 sites, two extensometers are installed at different depths (one shallow and one deep). The cumulative compaction data for each extensometer are collected about 13 times per year during site visits. Cumulative compaction data collected by each extensometer is provided, starting with the data from the year the extensometer was installed through most recently completed year (2017). The amount of cumulative compaction for each site visit is determined by subtracting the previously recorded compaction value from the ending compaction value.

Maumee River, Toledo, Ohio Mixing Data 2013

These data were collected to examine water mixing in the lower Maumee River to determine the extent to which water from Lake Erie backflows into the river, and under what conditions this occurs. We used a combination of fixed hydrologic gauges; water chemistry including stable isotopes and conservative tracers; and direct physical measurements to estimate the percentages of lake and river water at both fixed sites and transects.  Those results were compared with concurrent flows and estimates of seiche activity. Data suggest that during 2013 mixing did occur, but was confined to the lowest river reach within the city limits of Toledo, Ohio. This tabular data set could be used for any questions involving large river water chemistry or physical processes. It includes boron and magnesium measurements, isotope data, sonde transect data, and sonde vertical profile data.

Time-Domain Electromagnetic Data Used in the Hydrogeologic Framework Development and Refinement for the Ogallala and Edwards-Trinity Aquifers In and Near Gaines, Terry, and Yoakum Counties, Texas

Declining groundwater levels in and near Gaines, Yoakum, and Terry Counties in the Texas Panhandle have raised concerns about the amount of available groundwater and the potential for water-quality changes resulting from dewatering and increased vertical groundwater movement between adjacent water-bearing hydrogeologic units. More than 9,800 well records, such as geophysical logs, drilling descriptions, and published hydrogeologic framework information, were evaluated to help characterize the framework of hydrogeologic units in the study area. Additional geophysical data were collected to improve the spatial coverage across the study area and to reduce uncertainty with regard to hydrogeologic unit extents. Of greatest interest was gaining a refined understanding of how the saturated thickness of the Ogallala and Edwards-Trinity aquifers vary throughout the study area.

Determine nutrient conditions, cycling, and biological effects in two riverine parks, St.Croix National Scenic River (SACN) and Upper Mississippi River National Recreation Area (MNRA): Data

Hydraulic connection between channels and floodplains (“connectivity”) is a fundamental determinant of ecosystem function in large floodplain rivers.  Factors controlling material processing in these rivers depend not only on the degree of connectivity but also on the sediment conditions, nutrient loads and source.  Nutrient cycling in the nutrient-rich upper Mississippi River (MISS) is relatively well studied, while that of less eutrophic tributaries is not (e.g., St Croix River; SACN).  We examined components of nitrogen cycling in two floodplain rivers of contrasting nutrient enrichment and catchment land-use to test the hypothesis that N-cycling rates will be greater in the MISS with elevated nutrient-loads and productivity in contrast to the relatively nutrient-poor SACN.  Nitrate (NO3-N) concentrations were highest in flowing habitats in the MISS and often undetectable in isolated backwaters (IBW) except where groundwater inputs occurred.  In the SACN, (NO3-N) concentrations were greatest in the flowing backwater (FBW) where groundwater inputs were high.  Ambient nitrification in the MISS was 2x that in SACN and tended to be lowest in the main channel (MC). Denitrification was 3x higher in the MISS than SACN; N-limited in both rivers. Community P/R (production/respiration) was &gt;1 in the MISS and likely provisioned labile C to fuel microbial metabolism and dissimilatory NO3-N reduction, while the heterotrophic (P/R&lt;1) nature of the SACN likely limited microbial metabolism and NO3-N dissimilation.  It appears that N-cycling in the SACN was driven by groundwater, while that in the MISS was supported mainly by water column N-sources.

Water Quality data from the Providence Water Supply Board for tributary streams to the Scituate Reservoir, water year 2016

Water-quality data were collected by the Providence Water Supply Board (PWSB) from tributaries in the Scituate Reservoir drainage area, October 2015 through September 2016 (water year 2016). These data were used to calculate instantaneous loads and yields of constituents in a report by the U.S. Geological Survey. Water-quality samples were collected by the PWSB either monthly or quarterly at fixed stations on 34 tributaries in the Scituate Reservoir drainage area. Water-quality samples were collected following a strict sampling schedule so that water-quality samples would be representative of various weather conditions. Samples were analyzed at the PWSB water-quality laboratory at the P.J. Holton Water Purification Plant in Scituate, Rhode Island. Water-quality properties and constituent concentrations were measured by using unfiltered water samples. These water-quality properties included pH, alkalinity, color, turbidity, and concentrations of chloride, nitrite, nitrate, orthophosphate, and bacteria (Escherichia coli [E. coli] and total coliform).
