GFLOW groundwater flow model for the northern part of the Nicolet Unit of the Chequamegon-Nicolet National Forest, Wisconsin

The model simulates two-dimensional groundwater flow and base flow in streams in the 
northern Nicolet Unit of the Chequamegon-Nicolet National Forest using the analytic 
element program GFLOW (Haitjema, 1995). Significant streams and lakes in the model 
domain are represented at varying levels of detail as linesink elements fully connected 
to the groundwater system. The highest level of detail is given to surface water features 
within the Forest Unit, while greatly simplified features around the perimeter of the model 
provide a boundary condition for the groundwater flow system. Groundwater discharge 
to the linesinks is computed, and routed through the surface water network as base flow. 
Recharge to the groundwater system was obtained from a separate soil-water-balance 
(SWB) model, which uses topography, soils, land use, and climatic data to estimate 
recharge as deep drainage from the soil zone. Estimated average annual recharge rates 
were supplied to the GFLOW model on a regular 1-km grid covering the model domain, 
using the Hybrid GFLOW-MODFLOW feature of GFLOW.
		
The model was calibrated to groundwater levels, interpreted lake stages, and estimated 
annual base flows in streams, \with an emphasis on data collected since 1970. Parameters 
representing hydraulic conductivity, groundwater recharge, and surface water bed-sediment 
resistance were adjusted using the parameter estimation program PEST, to produce 
simulated groundwater levels and base flow estimates that agree with field measurements, 
and input parameter values that are consistent with previous studies and the conceptual 
understanding of the area. This USGS data release contains all of the input and output 
for the simulations described in the published report, which can be found in the main 
directory of this data release.

A Digital Hydrologic Network Supporting NAWQA MRB SPARROW Modeling--MRB_E2RF1WS

A digital hydrologic network was developed to support SPAtially Referenced Regression on Watershed 
attributes (SPARROW) models within selected regions of the United States. These regions correspond 
with the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program Major River 
Basin (MRB) study units 2, 3, 4, 5, and 7 (Preston and others, 2009).  MRB2, covers the South 
Atlantic-Gulf and Tennessee River basins.  MRB3, covers the Great Lakes, Ohio, Upper Mississippi, 
and Souris-Red-Rainy River basins.  MRB4, covers the Missouri River basins.  MRB5, covers the 
Lower Mississippi, Arkansas-White-Red, and Texas-Gulf River basins.  MRB7, covers the Pacific 
Northwest River basins. 
		
The digital hydrologic network described here represents surface-water pathways (MRB_E2RF1) 
and associated catchments (MRB_E2RF1WS). It serves as the fundamental framework to spatially 
reference and summarize explanatory information supporting nutrient SPARROW models (Brakebill 
and others, 2011; Wieczorek and LaMotte, 2011). The principal geospatial dataset used to support 
this regional effort was based on an enhanced version of a 1:500,000 scale digital stream-reach 
network (ERF1_2) (Nolan et al., 2002). Enhancements included associating over 3,500 water-quality 
monitoring sites to the reach network, improving physical locations of stream reaches at or near 
monitoring locations, and generating drainage catchments based on 100m elevation data.
		
A unique number (MRB_ID) identifies each reach as a single unit. This unique number is also shared 
by the catchment area drained by the reach, thus spatially linking the hydrologically connected 
streams and the respective drainage area characteristics. In addition, other relevant physical, 
environmental, and monitoring information can be associated to the common network and accessed 
using the unique identification number.

Ship tracklines along which continuous resistivity profiling data were collected in the Indian River Bay, Delaware, on April 14, 2010, on U.S. Geological Survey Field Activity 2010-006-FA (JD104GPS_LINES.SHP, Geographic, WGS 84)

A geophysical survey to delineate the fresh-saline groundwater interface and associated sub-bottom sedimentary structures beneath Indian River Bay, Delaware, was carried out in April 2010. This included surveying at higher spatial resolution in the vicinity of a study site at Holts Landing, where intensive onshore and offshore studies were subsequently completed. The total length of continuous resistivity profiling (CRP) survey lines was 145 kilometers (km), with 36 km of chirp seismic lines surveyed around the perimeter of the bay. Medium-resolution CRP surveying was performed using a 50-meter streamer in a bay-wide grid. Results of the surveying and data inversion showed the presence of many buried paleochannels beneath Indian River Bay that generally extended perpendicular from the shoreline in areas of modern tributaries, tidal creeks, and marshes. An especially wide and deep paleochannel system was imaged in the southeastern part of the bay near White Creek. Many paleochannels also had high-resistivity anomalies corresponding to low-salinity groundwater plumes associated with them, likely due to the presence of fine-grained estuarine mud and peats in the channel fills that act as submarine confining units. Where present, these units allow plumes of low-salinity groundwater that was recharged onshore to move beyond the shoreline, creating a complex fresh-saline groundwater interface in the subsurface. The properties of this interface are important considerations in construction of accurate coastal groundwater flow models. These models are required to help predict how nutrient-rich groundwater, recharged in agricultural watersheds such as this one, makes its way into coastal bays and impacts surface water quality and estuarine ecosystems. For more information on the survey conducted for this project, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-006-FA.

Imagery from USGS CoastCam deployed at Madeira Beach, Florida

A digital video camera was installed at Madeira Beach, Florida (FL) and faced west along the beach. Every hour during daylight hours, daily from 2017 to 2022, the camera collected raw video and produced snapshots and time-averaged image products. The images included in this data release were collected from January 21, 2017, to December 31, 2017. The camera is part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. USGS researchers analyzed the imagery collected from this camera to remotely sense a range of information including shoreline position, sandbar migration, wave run-up on the beach, alongshore currents, and nearshore bathymetry. This camera is part of the USGS CoastCam network, supported by the Total Water Level/Coastal Change Project under the Coastal and Marine Hazards and Resources Program (CMHRP).

JPEG Images of Cores Collected in August 2006 in the Nauset Marsh Area of Cape Cod, Massachusetts

In order to test hypotheses about groundwater flow under and into estuaries and the Atlantic Ocean, geophysical surveys, geophysical probing, submarine groundwater sampling, and sediment coring were conducted by U.S. Geological Survey (USGS) scientists at Cape Cod National Seashore (CCNS) from 2004 through 2006. Coastal resource managers at CCNS and elsewhere are concerned about nutrients that are entering coastal waters via submarine groundwater discharge, which are contributing to eutrophication and harmful algal blooms. The research carried out as part of the study described here was designed, in part, to help refine assumptions required by earlier versions of models about the nature of submarine groundwater flow and discharge at CCNS. This study was conducted in four phases, with a variety of field techniques and equipment employed in each phase. Phase 1 consisted of continuous resistivity profiling (CRP) surveys of the entire study area conducted in 2004. Phase 2 consisted of CRP ground-truthing via resistivity probe measurements and submarine groundwater sampling from hydraulically-drive piezometers using a barge in the Salt Pond/Nauset Marsh area in 2005. Phase 3 consisted of supplemental detailed CRP surveys in the Salt Pond/Nauset Marsh area in 2006. Finally, Phase 4 consisted of sediment coring and porewater extraction in the Salt Pond/Nauset Marsh area later in 2006 to supplement the 2005 sampling.

Nearshore water level, tide, and non-tidal residual future projections (2016-2050) for the U.S. Atlantic coast

A dataset of modeled nearshore water levels (WLs) was developed for three states (Virginia, Georgia, and Florida) along the U.S. Atlantic coast. Water levels, defined for this dataset as the linear sum of tides and non-tidal residuals (NTR), were produced by Muis and others (2016) using a global tide and surge model (GTSM) forced by global atmospheric fields. Water level outputs were extracted from the global grid at approximately 20 km resolution along the Atlantic coastline. These data were then statistically downscaled using a signal-specific set of corrections to improve skill in comparison to tide gauge observations  (Parker and others, 2023). Projected water levels were forced by CMIP6 future period data. Four CMIP6 climate models were selected from the High-Resolution Model Intercomparison project (highresMIP; Haarsma and others, 2016) to sample variability in climate predictions. Similar modeled data for North Carolina and South Carolina are available from Barnard and others, 2023, at https://doi.org/10.5066/P9W91314)

Interpretation of road locations in the John Day Reservoir based on sidescan-sonar imagery

A two-week field operation was conducted in the John Day Reservoir on the Columbia River to image the floor of the pool, to measure the distribution and thickness of post-impoundment sediment, and to verify these geophysical data with video photography and bottom sediment samples. The field program was a cooperative effort between the USGS Coastal and Marine Geology Team of the Geologic Division and the USGS Columbia River Research Laboratory of the Biological Resources Division. The data collection was completed aboard the R/V ESTERO during September 13-27, 2000. The interest in sediment accumulation in the reservoir was two-fold. First, it was unknown how effective this reservoir was as a sediment trap to material that otherwise would have been transported down-river to the estuary and eventually to the ocean. The recent erosion of beaches along the Washington coast has been attributed to a decreased contribution of sediment from the Columbia River to the coastal system due to the damming of the river. Second, sediment accumulation on the floors of reservoirs along the Columbia River has been suggested to be diminishing salmon spawning grounds. The extent of changes in habitat since construction of the John Day Dam, however, had not been documented. Common data sets were needed to address both of these questions, and for these reasons this geophysical and sampling program was undertaken.

Text Files of the DGPS Navigation Logged with HYPACK Software on U.S. Geological Survey Cruise 2012-002-FA from June 11 to June 14, 2012

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetric and sidescan-sonar data, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2012, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sidescan-sonar, sedimentary, and photographic data collected in Block Island Sound.

Airborne geophysical survey: Delaware Fall Zone

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. In the earlier days of surveying, the only way to represent this data was to generate an analog map with contour lines. This dataset is a representation of the digitized contour lines either by following the lines or by choosing the intersection of the contour and flight-line to create a value of the magnetic field. The values presented are latitude, longitude, and map magnetic-field values.
