MODFLOW-2000 and MODPATH4 used to simulate groundwater flow and contaminant transport in the Pohatcong Valley, Warren County, New Jersey

The U. S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, 
developed a numerical ground-water-flow model, using MODFLOW-2000, to simulate 
ground-water flow in the Pohatcong Valley including the area within the Pohatcong Valley 
Ground Water Contamination Site. In 1978, the chlorinated solvents trichloroethene (TCE) 
and tetrachloroethene (PCE) were detected in thePohatcong Valley in production wells in 
Washington Borough and Washington Township, Warren County, New Jersey. Subsequent 
investigation revealed that many domestic wells in Washington and Franklin Townships 
also were contaminated, and in 1989 the Pohatcong Valley Ground Water Contamination 
Site was added to the U.S. Environmental Protection Agency (USEPA) National Priority List. 
A remedial investigation, by the USEPA and CH2M Hill with technical assistance from the 
U.S. Geological Survey (USGS), was begun in 1999.  The simulation of ground-water flow in 
the Pohatcong Valley described here was conducted by the USGS in cooperation with the 
USEPA. The ground-water-flow model, using MODFLOW-2000 and the particle–tracking 
program MODPATH, estimated flow paths of groundwater from known sources of contamination 
in Washington Borough and tested possible site contamination remediation alternatives. Five 
ground-water remediation alternatives (GW2a, GW2b, GW3a, GW3b, and GW4b) were 
simulated. In addition, a 10-year solute transport simulation was conducted, using the USGS 
groundwater-transport process, to illustrate the potential for dispersion to increase the width of 
the solute plume.  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/sir20065269).

Esri Binary 2-m Bathymetric Grid of National Oceanic and Atmospheric Administration (NOAA) Survey H12023 in Block Island Sound (H12023_2M_GEO, Geographic, WGS84)

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.

MODFLOW, MT3D-USGS and VS2DH simulations used to estimate groundwater and nutrient inflow to Upper Klamath Lake, Oregon

This model archive data release includes all models used to characterize the magnitude, 
spatial distribution and timing of groundwater (GW) flow through lakebed sediments to 
Upper Klamath Lake (UKL), Oregon, described in the associated journal article 
(https://doi.org/10.1016/j.scitotenv.2020.142768). One-dimensional vertical models 
of GW flow (MODFLOW-2005) and solute transport (MT3D-USGS) were calibrated 
(UCODE) to 2014 observed dissolved silica (Si, 0.2-micron filtered) porewater 
concentrations in the upper 0.1 m of lakebed sediment to estimate GW flow and 
Si exchange across the lakebed interface. The Si-based calibrated GW flow rates 
were then used in conjunction with observed dissolved phosphate-phosphorus (PP) 
porewater concentrations in the upper 0.1 m of lakebed sediment to estimate the 
amount of PP reacted during upward flow through the lakebed sediment and the 
PP discharge to the lake. One-dimensional, vertical GW flow and heat transport 
models (VS2DH) were calibrated (UCODE) to 2015 and 2017 observed lakebed 
temperatures to provide estimates of GW-inflow rates at multiple UKL locations. 
Calibrated GW inflows were greatest in the spring and decreased through the 
summer. The magnitude and timing of the GW-lake water exchange estimates 
obtained from these methods were compared to rates obtained from a generalized 
cross-sectional GW flow model (MODFLOW-NWT) with time-varying recharge. 
The cross-sectional GW flow model demonstrated that snow-melt GW recharge 
could be transported rapidly to the lake due to the relatively high permeability and 
low specific storage of the surrounding volcanic rocks explaining the greater GW 
discharge to the lake in the spring. This USGS data release contains all the input 
and output files for the simulations described in the associated journal article 
(https://doi.org/10.1016/j.scitotenv.2020.142768).

Tracklines of swath bathymetry collected by the U.S. Geological Survey - Woods Hole Coastal and Marine Science Center offshore of the Gulf Islands, MS, 2010 (ESRI polyline shapefile, 2010-012-FA_subx_Tracklines.shp)

In 2010, the U.S. Geological Survey in Woods Hole, MA and St. Petersburg, FL, in partnership with the U.S. Army Corps of Engineers, Mobile District conducted geologic mapping to characterize the seafloor and shallow subsurface stratigraphy offshore of the Gulf Islands of Mississippi. The mapping was carried out during two cruises in March, 2010 on the R/V Tommy Munro of Biloxi, MS. Data were acquired with the following equipment: an SEA Ltd SwathPlus interferometric sonar (both 234 kHz and 468 kHz systems), a Klein 3000 and a Klein 3900 dual frequency sidescan-sonar, and an Edgetech 512i chirp subbottom profiling system. The long-term goal of this mapping effort is to produce high-quality, high-resolution geologic maps and geophysical interpretations that can be utilized to identify sand resources within the region and better understand the Holocene evolution and anticipate future changes in this coastal system.

Station and data summary for data collected on Stellwagen Bank during U.S. Geological Survey field activity 2017-043-FA, aboard the R/V Auk, Aug. 22 and 23, 2017 (geographic, WGS84)

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.

Digital surface model representing Head of the Meadow Beach, Truro from images taken during field activity 2020-015-FA on March 6, 2020

The data in this release map the beach and nearshore environment at Head of the Meadow Beach in Truro, MA and provide environmental context for the camera calibration information for the 2019 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is related to the field activity 2020-015-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region that falls within the field of view of the CoastCam, which are two video cameras aimed at the beach. On March 4, 6, and 10, 2020, U.S Geological Survey and Woods Hole Oceanographic Institution (WHOI) scientists conducted field surveys to collect position and orientation information for the CoastCam cameras and map the field of view. Elevation data were collected using a real time kinematic – satellite navigation system (RTK-GNSS) receiver attached to a pole and walked on the beach. Point data of the beach face were collected along transects and at periodic locations of plywood targets moved throughout the day within the CoastCam view. Grain-size analysis was performed on sediment samples collected with a spade along multiple profiles from the bluff base to the intertidal zone. Images of the beach were taken with a camera (Ricoh GRII) and a post-processed kinematic (PPK) system attached to a kitesurfing kite, and high-precision targets (AeroPoints) were used as ground control points. Bathymetry was collected in the nearshore using a single-beam echosounder mounted on a surf capable self-righting electric autonomous survey vehicle. Agisoft Metashape (v. 1.6.1) was used to create a digital elevation model with the collected imagery and this was merged with the bathymetry in MatLab (v. 2020) to create a continuous topobathy product.
