Site 33 Mississippi River Bathymetry and Velocimetry Data at Structure A6500 on Interstate 70 in St. Louis, Missouri, July 2009 and May 2016

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in ASCII format, generated from hydrographic and velocimetric surveys of the Mississippi River near structure A6500 on Interstate 70 in St. Louis, Missouri, in 2009 and 2016.  Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel.  Data were collected as the vessel traversed the river along planned survey lines distributed throughout the reach.  Data collection software integrated and stored the depth data from the MBES and the horizontal and vertical position and attitude data of the vessel from the INS in real time.  Data processing required computer software to extract bathymetry data from the raw data files and to summarize and map the information.  Velocity data were collected using an acoustic Doppler current profiler (ADCP) mounted on a survey vessel equipped with a differential global positioning system (DGPS).  Data were collected as the vessel traversed the river along planned transect lines distributed throughout the reach. Velocity data were processed using the Velocity Mapping Toolbox (Parsons and other, 2013), and smoothed using neighboring nodes.

Annual Channel Geomorphology Cross-Section Surveys 2005-2012 in Roanoke, Virginia

Geomorphology monitoring sites at 15 locations along the Roanoke River in Salem and Roanoke, Virginia, represented riffle or pool habitats and were designed to facilitate repeated measuring at the same cross section over time.  Local bench marks were installed at each site to provide both horizontal and vertical control.  At a minimum, each site had two bench marks (designated BM) and two transect control marks (designated TC) that were tied together through a static survey-grade Global Positioning System (GPS) survey to establish control to the nearest centimeter.  
Annual cross-section topographic surveys were conducted during summer low-flow periods at the 15 geomorphology monitoring sites using a total station from 2005 to 2012 at each site. Floodplains, banks, channels, and water-surface elevations were surveyed, with each survey beginning on the floodplain a minimum of 50 ft from the active channel.  Floodplain features were surveyed on 5-10-ft intervals and at major breaks in slope, channel banks were surveyed on 1-5-ft intervals, and the active channel was surveyed on 1-2-ft intervals to document channel changes with greater resolution.  Most sites had one bank that was steeper and more vegetated than the other; bank steepness occasionally prevented complete surveying of the banks, in which case the survey was continued up the bank as far as possible. Pools were surveyed from a canoe when depths prohibited wading.  Water-surface slope within 10 meters upstream and downstream of the cross section was surveyed most years for evaluation of changes in gradient.

Ammodramus savannarum ammolegus Grasshopper Sparrow bird measurements Arizona 2010-2013

In 2010-2013 a variety of measurements were taken from grasshopper sparrows captured as part of the study described below and referenced in the larger work citation of this metadata record.  Measurements include age, sex, wing length, weight, and exposed culmen length.
Ammodramus savannarum ammolegus (commonly referred to as the Arizona Grasshopper Sparrow) occurs in the desert and plains grasslands of southeastern Arizona, southwestern New Mexico, and northern Sonora, Mexico.  Although a subspecies of conservation concern, this is the first intensive study of its life history and breeding ecology, providing baseline data and facilitating comparisons with other North American Grasshopper Sparrow subspecies.  Specifically, I found that ammolegus males generally weighed less than other subspecies (16.0 ± 0.8 g), but with intermediate exposed culmen length (11.6 ± 0.5 mm) and wing chord length similar to the other two migratory subspecies (62.7 ± 1.5 mm).  Territory size for ammolegus was 0.72 ± 0.37 ha, with some variation between sites and among years, possibly indicating variation in habitat quality across spatial and temporal scales.  The return rate for ammolegus males was 39.2%.  Nest initiation for ammolegus was early to mid-July after the monsoons had begun.  Domed nests were constructed on the ground, primarily under native bunch grasses, and frequently with a tunnel extending beyond the nest rim, with nest openings oriented north.  Clutch size was 3.97 ± 0.68, with no evidence of Brown-headed Cowbird (Molothrus ater) nest parasitism.  Extreme climate factors in the arid Southwest may have affected the life history and morphology of ammolegus as compared to other subspecies, influencing body size and mass, culmen length, breeding phenology, and nest orientation.  Other geographic variation occurred in return rates, clutch size, and nest parasitism rates.  The baseline data for ammolegus obtained in this study will inform future taxonomic and ecological studies as well as conservation planning.  Comparisons of ammolegus morphometrics with those of other subspecies will assist field biologists in distinguishing among subspecies where they overlap, especially on wintering grounds.

Water Quality Profiles for Bushy Park Reservoir

The Bushy Park Reservoir is a relatively shallow impoundment in a semi-tropical climate and is the principal water supply for the 400,000 people of the City of Charleston and the surrounding areas including the industries in the Bushy Park Industrial Complex. Although there is an adequate supply of freshwater in the reservoir, there are taste-and-odor water-quality concerns. The U.S. Geological Survey (USGS) worked in cooperation with the Charleston Water System to study the hydrology and water-quality of the Bushy Park Reservoir to identify factors affecting water-quality conditions. This data release is for water-quality profiles collected with a hand-held calibrated field meter from a manned boat concurrent with the autonomous underwater vehicle (AUV) water-quality surveys to identify and verify diurnal- and depth-related changes during the water-quality surveys. Data includes water temperature, specific conductance, pH, dissolved oxygen, turbidity, chlorophyll, and blue-green algae.

Shorelines of the Central Beaufort Sea, Alaska coastal region (Hulahula River to the Colville River) used in shoreline change analysis

This dataset includes shorelines from 63 years ranging from 1947 to 2010 for the north coast of Alaska between the Hulahula River and the Colville River. Shorelines were compiled from topographic survey sheets (T-sheets; National Oceanic and Atmospheric Administration (NOAA)), aerial orthophotographs (U.S. Geological Survey (USGS), National Aeronautics and Space Administration (NASA), Conoco-Philips (CP), British Petroleum Alaska (BPXA)), satellite imagery (State of Alaska), and lidar elevation data (USGS). Historical shoreline positions serve as easily understood features that can be used to describe the movement of beaches through time. These data are used to calculate rates of shoreline change for the U.S. Geological Survey's National Assessment of Shoreline Change Project. Rates of long-term and short-term shoreline change were generated in a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3. DSAS uses a measurement baseline method to calculate rate-of-change statistics. Transects are cast from the reference baseline to intersect each shoreline, establishing measurement points used to calculate shoreline change rates.
