Hydrographic surveys collected to monitor fish spawning reef placements, Detroit River, Michigan, June 23-24, 2015
The U.S. Geological Survey conducted hydrographic surveys from June 23-24, 2015, to monitor fish spawning substrate placements (reefs) in the Detroit River, Michigan. An interferrometric multibeam echosounder was used from the Great Lakes Science Center research vessel Mayfly to collect maps of river bottom topography in locations where spawning substrates have been placed. In addition, baseline topography was collected at locations where substrates were planned to be introduced. The Fighting Island reef had been constructed at the date of survey. Surveys were also conducted at prospective reef sites: Grassy Island, Fort Wayne and Upstream Belle Isle. This data release includes bathymetric surveys collected from...
The U.S. Geological Survey, in collaboration with the Water Resources University in Hanoi, Vietnam, conducted a bathymetric survey of the junction of the Hong and Luoc Rivers. The survey was carried out in December 2010 using a boat-mounted multibeam echo sounder integrated with a global positioning system. A bathymetric map of the Hong and Luoc River junction was produced which was referenced to the datum of the Trieu Duong tide gage on the Luoc River. This data release contains the data used to produce the bathymetric map.
Estimates of various low-flow statistics were computed at 71 ungaged stream locations throughout New Jersey during the 2017 water year using methods in the published reports, Streamflow Characteristics and Trends in New Jersey, Water Years 1897-2003 (U.S. Geological Survey Scientific Investigations Report 2005-5105) and Implementation of MOVE.1, Censored MOVE.1, and Piecewise MOVE.1 Low-Flow Regressions With Applications at Partial-Record Streamgages in New Jersey (U.S. Geological Survey Open File Report 2018-1089). The estimates are computed as needed for use in water resources permitting, assessment, and management by the New Jersey Department of Environmental Protection. The data release includes the stream name,...
ADCP data were collected on two separate occasions (May 14-15, 2013 and May 28, 2013) in the Marseilles Pool on the Illinois River using a Teledyne Rio Grande 1200 kHz Acoustic Doppler Current Profiler with integrated Trimble GPS. ADCP data was collected in reciprocal pairs along cross-sections and along roughly streamwise oriented lines between cross-sections. The data are provided in: (1) a zipped folder containing classic ascii output files exported from WinRiverII software, and a README text file indicating which files are reciprocal pairs, and which files are streamwise oriented lines (2) a zipped folder containing KML files for each transect.
Update to the groundwater withdrawals database for the Death Valley regional groundwater flow system, Nevada and California, 1913-2010
Groundwater withdrawal estimates from 1913-2010 for the Death Valley regional groundwater flow system (DVRFS) are compiled in a Microsoft® Access database. This database updates two previously published databases (Moreo and others, 2003; Moreo and Justet, 2008). A total of about 38,000 acre-feet of groundwater was withdrawn from the DVRFS in 2010, of which 47 percent was used for irrigation, 22 percent for domestic, and 31 percent for public supply, commercial, and mining activities. The updated database was compiled to support ongoing efforts to model groundwater flow in the DVRFS. References cited: Moreo, M.T., Halford, K.J., La Camera, R.J., and Laczniak, R.J., 2003, Estimated ground-water withdrawals from the...
We developed an age-structured population matrix model to perform population viability analysis for Lower Missouri River (LMR) shovelnose sturgeon (Scaphirhynchus platorynchus). We investigated potential effects of the commercial fishing moratorium put in place to help protect the similar-appearing pallid sturgeon (S. albus). The model applies different components of total variance in life history parameters at different levels: sampling variance (parameter uncertainty) between model iterations; temporal variance (temporal environmental fluctuations) between time steps within iterations; and individual variance (individual differences) within each time-step. The model predicted annual rates of population increase...
This is a collaborative, two-part project to compile and analyze resource data to support WLCI efforts. Part 1 entails directing data synthesis and assessment activities to ensure that they will inform and support the WLCI LPDTs and Coordination Team in their conservation planning efforts, such as developing conservation priorities and strategies, identifying priority areas for conservation actions, evaluating and ranking conservation projects, and evaluating spatial and ecological relations between proposed habitat projects and WLCI priorities. In FY2014, we helped the Coordination Team complete the WLCI Conservation Action Plan and BLM’s annual report, and we provided maps and other materials to assist with ranking...
The activities associated with the construction of a new walkway within Mammoth Cave caused vibrations to be felt in the cave, which is home to an endangered Indiana bat roost. These data were collected at the request of the National Park Service to monitor the vibration levels near a bat roost within Mammoth Cave National Park to determine if construction-induced vibration might be inducing the observed activity of the bats. Seven geophones and two accelerometers were placed in the passage to the bat roost to monitor the distribution of ground velocity and acceleration. The vibration signature of individual construction equipment (jackhammer, place compactor, and hammer drill), human activities during a simulated...
Subduction zones are home to the most seismically active faults on the planet. The shallow megathrust interface of subduction zones host our largest earthquakes, and are the only faults capable of M9+ ruptures. Despite these facts, our knowledge of subduction zone geometry - which likely plays a key role in determining the spatial extent and ultimately the size of subduction zone earthquakes - is incomplete. Here we calculate the three- dimensional geometries of all active global subduction zones. The resulting model - Slab2 - provides for the first time a comprehensive geometrical analysis of all known slabs in unprecedented detail.
Estimates of various low-flow statistics were computed at 61 ungaged stream locations throughout New Jersey during the 2016 water year using methods in the report, Streamflow Characteristics and Trends in New Jersey, Water Years 1897-2003 (U.S. Geological Survey Scientific Investigations Report 2005-5105). The estimates are computed as needed for use in water resources permitting, assessment, and management by the New Jersey Department of Environmental Protection. The data release includes the stream name, location, method, and intended use of the low-flow statistics computed during the 2016 water year. The data are provided as both a plain text file and an ArcGIS shapfile format.
