Magnetotelluric sounding data, station 35, San Luis Valley, Colorado, 2007

This dataset includes the magnetotelluric (MT) sounding data collected in 2007 in and near the San Luis Valley, Colorado. The U.S. Geological Survey conducted a series of multidisciplinary studies, including MT surveys, in the San Luis Valley to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers of the Rio Grande rift. The shallow unconfined and the deeper confined Santa Fe Group aquifers in the San Luis Basin are the main sources of municipal water for the region. The population of the San Luis Valley region is growing rapidly and water shortfalls could have serious consequences. Future growth and land management in the region depend on accurate assessment and protection of the region's groundwater resources.

SeaBOSS sea floor images from cruise SUN00030: JPEG format

Pulley Ridge is a series of drowned barrier islands that extends almost 200 km in 60-100 m water depths. This drowned ridge is located on the Florida Platform in the southeastern Gulf of Mexico about 250 km west of Cape Sable, Florida. This barrier island chain formed during the initial stage of the Holocene marine transgression. These islands were then submerged and left abandoned near the outer edge of the Florida Platform. The southern portion of Pulley Ridge hosts zooxanthellate scleractinian corals, green, red and brown macro algae, and a mix of deep and typically shallow-water tropical fishes. This reef community is in unusually deep water, and its extent and the controls on its distribution were unknown. To address these questions scientists from the U.S. Geological Survey Coastal and Marine Geology Program in cooperation with scientists from the University of South Florida Department of Marine Sciences have completed a detailed mapping of the southernmost 35 km of Pulley Ridge. The area was mapped using multibeam bathymetry, sidescan-sonar imagery, and high-resolution seismic-reflection profiling to define the geologic framework on which the reef is established. Submersible dives, remotely operated vehicle (ROV) transects, and transects of bottom photographs and video were collected to identify the corals and to map their distribution. This extensive suite of data has been compiled and preliminary analysis of the data suggests that the reefs are not tied to the ridge system, but instead are more broadly distributed. Whether reef distribution is controlled by oceanographic conditions or by subtle differences in the substrate that overlies the barrier island system is unclear, and are topics of continued research.

Bathymetry and Capacity of Shawnee Reservoir, Oklahoma, 2016

The U.S. Geological Survey (USGS), in cooperation with the City of Shawnee, performed a detailed bathymetric survey of Shawnee Reservoir in 2016. Shawnee Reservoir (locally known as Shawnee Twin Lakes) is a man-made reservoir on South Deer Creek in Pottawatomie County, Oklahoma. The reservoir consists of two lakes connected by an equilibrium channel. The southern lake (Shawnee City Lake Number 1) was impounded in 1935 and the northern lake (Shawnee City Lake Number 2) was impounded in 1960. Shawnee Reservoir has a normal pool elevation of 1,069.0 feet above North American Vertical Datum of 1988. The auxiliary spillway, which defines the flood pool, is at an elevation of 1,075.0 feet above North American Vertical Datum of 1988.

Compilation of Data on the Middle Savannah River  for the Analysis of Sub-Daily Flow Variation, 2011-2015

The Nature Conservancy (TNC) has been working with the U.S. Fish and Wildlife Service (USFWS), the U.S Army Corps of Engineers – Savannah District (USACE - Savannah) and other stakeholders on environmental flow recommendations for the Savannah River since May 2002 and have recently (2015) updated the environmental flow recommendations from 2003. Analysis of the flow data revealed a large amount of flow variability on sub-daily basis in the reach of the Savannah River from the Augusta Shoal downstream to the New Savannah Lock and Dam.  The sub-daily flow variability affects sustaining suitable habitat during critical periods to promote fish spawning of robust redhorse, shad, and Atlantic sturgeon.  The cause of the flow variability is hypothesized to be a result of the interaction of flow releases by two upstream hydroelectric facilities (Strom Thurmond Lake and Stevens Creek Hydroelectric Facility [Stevens Creek]) and backwater conditions. An important goal of the USACE Sustainable River Program (SRP) is to improve the health of rivers by changing the operations of reservoirs. Important tasks to meet this goal include work to: improve the understanding of existing hydrologic, ecological and socio-economic conditions at project sites; to refine environmental flow needs; and improve reservoir operations.  
To better understand how these upstream flow releases interact, a time-series database was compiled to evaluate the flows releases and the downstream variability. Stream temperature was included in the dataset because the sub-daily variability is more biologically critical during particular temperature ranges. Continuous monitoring data was obtained from the U.S. Geological Survey (USGS) and the USACE.  The South Carolina Electric and Gas Company (SCE&amp;G) provided data on the daily operation for Stevens Creek. The data were organized in monthly workbooks with one spreadsheet per day of the month. Scripts were written to parse the data from the various workbooks and spreadsheets into a continuous time series of hourly flow releases from Stevens Creek. The period for the compiled data set is January 1, 2011 to December 31, 2015. Time-series of time derivatives of daily change in flow at the USGS gaging station was computed. The measured and computed time-series data were compiled into a data viewer to facilitate the interrogation of the flow and temperature data and to visualize the interaction of the hydropower releases on downstream flow rates.
