Estimated Perennial Streams in Idaho

Perennial streams in Idaho have been modeled using regression 
equations for 7-day, 2-year low flows (7Q2) described in Wood 
and others (2009, U.S. Geological Survey Scientific Investigations 
Report 2009-5015). The model produces "synthetic" streams
based on 10-meter resolution digitial elevation models that have been
processed to agree closely with 1:24,000-scale National Hydrography
Dataset flowlines. Lines having attribute PerCode = 1 represent model
grid cells having 7Q2 flow estimates between 0.1 cubic feet per second
(ft3/s) and 0.1 minus the standard error for the applicable regional
regression equation. Lines having attribute PerCode = 2 represent model
grid cells having 7Q2 flow estimates between 0.1 ft3/s and 0.1 plus the
standard error for the applicable regional regression equation. Lines
having attribute PerCode = 3 represent model grid cells having 7Q2 flow
estimates greater than 0.1 ft3/s plus the standard error for the
applicable regional regression equation. These three categories of lines
indicate approximate levels of uncertainty in the model results, with
lines having PerCode = 1 representing the most uncertainty, and lines
having PerCode = 3 representing the least uncertainty with respect to
representing a perennial stream.

Baseline coastal oblique aerial photographs collected from Dauphin Island, Alabama, to Breton Island, Louisiana, September 26–27, 2006

The U.S. Geological Survey (USGS) conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms. On September 26-27, 2006, the USGS conducted an oblique aerial photographic survey from Dauphin Island, Alabama, to Breton Island, Louisiana, aboard a U.S. Coast Guard HH60 Helicopter aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore. This mission was conducted to collect data for assessing incremental changes in the beach and nearshore area since the last survey, which was flown in June 2006 (https://cmgds.marine.usgs.gov/fan_info.php?fan=06ACH02) and the data can be used to assess future coastal change. The photographs provided are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the aircraft's position and do not indicate the location of the features in the images. These photographs document the configuration of the barrier islands and other coastal features at the time  of the survey. ExifTool (version 4.0) was used to add the following to the header of each photograph: time of collection, GPS latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. Photographs can be opened with any JPEG-compatible image viewer. All image times are recorded in Coordinated Universal Time (UTC).

DS-777 Spatial Location of Gages with Total Flow and estimated Base Flow, organized by Seasonal Stress Periods for the Development Simulation Period for the Northern High Plains Groundwater-Flow Model in Parts of Colorado, Kansas, Nebraska, South Dakota, and Wyoming

Baseflow is the portion of streamflow derived from groundwater flow. It is an 
important component of the groundwater budget, and can be estimated using 
known total streamflow at given points through time. Daily streamflow data was 
collected from 91 streamflow gaging stations across the northern High Plains 
Groundwater Availability Study (NHPGAS) area from the National Water 
Information System (NWIS) and the Nebraska Department of Natural Resources 
Stream Gaging Data Bank. The data from each site was processed using the BFI 
program, version 4.15 (Wahl and Wahl, 2007) to determine the baseflow component 
of total streamflow at each site. The average daily baseflow was computed for the 
months of April and October, spanning the development period model (1940-2009). 
The resulting baseflow values were applied as calibration targets to corresponding 
stress periods.

Horizontal flow barriers for the transient ground-water flow model, Death Valley regional ground-water flow system, Nevada and California

This digital dataset defines the surface traces of regional features simulated as horizontal flow barriers 
in the Death Valley regional ground-water flow system (DVRFS) transient flow model, an approximately 
45,000 square-kilometer area of southern Nevada and California. The DVRFS transient groundwater flow 
model is one of several regional-scale models developed by the U.S. Geological Survey (USGS) for the 
U.S. Department of Energy (DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca 
Mountain, Nevada (see "Larger Work Citation", Chapter A, page 8). Initially, potential ground-water flow 
barriers were identified on the basis of length, offset, type of slip, orientation with respect to predominant 
ground-water flow directions, the location of springs, abrupt water level offsets, and hydraulic characteristics 
(Sweetkind and others, 2004). These potential flow barriers were tested in the transient ground-water flow 
model for effect on the simulated DVRFS flow system (Faunt and others, 2004). Ultimately, portions of 9 
features simulated as horizontal flow barriers were shown to retard flow in the calibrated DVRFS transient 
model.

Photomicrograph Images of Sediment Samples Collected at Crocker Reef, Florida, 2013-2014

Understanding the processes that govern whether a coral reef is accreting (growing) or dissolving are fundamental to questions of reef health and resiliency. A total of 52 surficial sediment samples were collected within a 1-km x 1-km area around Crocker Reef in the Florida Keys, USA, between 2013 and 2014.  Samples 1-35 were collected in July 2013 and samples 36-52 were collected in July 2014. The samples were processed using conventional, published techniques (see process step section) to yield grain size and mineralogical data. The dataset, CRKR2013-2014_SEDIMENT_Images.zip contains photomicrograph images that correspond to each sediment sample. These images also include additional, survey-specific EXchangable Image File format (EXIF) header information.

SEAWAT model used to evaluate the potential effects of alterations to the hydrologic system on the distribution of salinity in the Biscayne aquifer in Broward County, Florida: U.S. Geological Survey Data Release

A three-dimensional, variable-density solute-transport model (SEAWAT) was developed to examine 
causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system 
on salinity distribution in eastern Broward County, Florida. The model was calibrated to conditions 
from 1970 to 2012, the period for which data are most complete and reliable, and was used to 
simulate historical conditions from 1950 to 2012. The model was used to (1) evaluate the sensitivity 
of the salinity distribution in groundwater to sea-level rise and groundwater pumping , and (2) simulate 
the potential effects of increases in pumping, variable rates of sea-level rise, movement of a salinity 
control structure, and use of drainage recharge wells on the future distribution of salinity in the aquifer. 
This USGS data release contains all of the input and output files for the simulations described in the 
associated model documentation report (https://doi.org/10.3133/sir20165022). This data release 
also includes (1) preprocessing python scripts and associated input data files for creating the sensitivity 
and scenarios runs, (2) flopy source code, and (3) SEAWAT (v4) source code.

Still images in JPEG format of the sediment surface in the grab sampler, collected on Stellwagen Bank during U.S. Geological Survey field activity 2017-043-FA, aboard the R/V Auk, Aug. 22 and 23, 2017

This field activity is part of an effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000-scale) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. The data collected in this study will aid research on the ecology of fish and invertebrate species that inhabit the region. On August 22 and 23, 2017, the U.S. Geological Survey, in collaboration with the Stellwagen Bank National Marine Sanctuary, conducted a research cruise aboard the Sanctuary’s Research Vessel Auk, visiting 39 locations within the sanctuary. A customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a conductivity, temperature, and depth (CTD) instrument was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.

Continuous Resistivity Profile Tracklines of Data Collected from Cape Cod National Seashore, May 17-20, 2004

Continuous resistivity profiling (CRP) surveys were conducted at Cape Cod National Seashore in 2004 and 2006 in order to test hypotheses about groundwater flow under and into estuaries and the Atlantic Ocean. Coastal resource managers here and elsewhere are concerned about nutrients that are entering coastal waters via submarine groundwater discharge, which are contributing to eutrophication and harmful algal blooms. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to differences in salinity of submarine ground water. The 2004 and 2006 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software.
