JPEG Images of the Floor of the John Day Reservoir Acquired in 2002

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.

EC_Q15.TIF - U.S. Atlantic East Coast EEZ GLORIA sidescan-sonar data mosaic (15 of 23) (ACEA, 50 m, Clarke1866)

From February to May 1987 the U.S. Geological Survey (USGS) conducted five cruises to cover the U.S. Atlantic Continental Margin Exclusive Economic Zone (EEZ) seaward of the continental shelf edge, and from the Canadian border southward to the northern Blake Plateau off Florida. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. Twenty-three digital mosaics of a 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the U.S. Atlantic Continental Margin region.

Hydrographic Surveys of the Missouri River at Plattsmouth backwater, 2011-13

An Innerspace 456 single-beam echosounder in conjunction with a Trimble® differential Global Positioning 
System (DGPS), HYPACK® navigation software, and Ashtech Z-Xtreme and Trimble® R8 Global Navigation 
Satellite System (GNSS) receivers was used to survey 7 chutes and 3 backwaters on the Missouri River 
yearly from 2011-13. These chutes and backwaters are located on the Missouri River between Newcastle, 
Nebraska and Rulo, Nebraska in the States of Nebraska, Iowa, and Missouri.  Surveys of chutes consisted 
of topographic and bathymetric data collected along transects spaced 30.48 m apart from high bank to high 
bank.  Surveys of backwaters consisted of topographic and bathymetric data collected along a transect grid 
of 76.2 m spacing. The data were collected by the U.S. Geological Survey in cooperation with the U.S. Army 
Corps of Engineers (USACE) Omaha District as part of the Missouri River Habitat Assessment and Monitoring 
Program.

Shot point navigation at 100 shot intervals for EdgeTech SB-512i chirp seismic-reflection data collected in May 2012 by the U.S. Geological Survey within the Norfolk Canyon, mid-Atlantic margin (Esri point shapefile, Geographic, WGS 84, NC_all100shot.shp)

A large number of high-resolution geophysical surveys between Cape Hatteras and Georges Bank have been conducted by federal, state, and academic institutions since the turn of the century. A major goal of these surveys is providing a continuous view of bathymetry and shallow stratigraphy at the shelf edge in order to assess levels of geological activity during the current sea level highstand.  In 2012, chirp seismic-reflection data was collected by the U.S. Geologial Survey aboard the motor vessel Tiki XIV near three United States mid-Atlantic margin submarine canyons. These data can be used to further our understanding of passive continental margin processes during the Holocene, as well as providing valuable information regarding potential submarine geohazards. For more information on the U.S. Geological Survey involvement in this effort, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2012-005-FA.

Area of aquifer contours enhanced with airborne electromagnetic (AEM) surveys of the principal aquifer for portions of the North Platte, South Platte, and Twin Platte Natural Resources Districts, western Nebraska

The U.S. Geological Survey and its partners have collaborated to complete airborne 
geophysical surveys for areas of the North and South Platte River valleys and 
Lodgepole Creek in western Nebraska. The objective of the surveys was to map 
the aquifers and bedrock topography of selected areas to help improve the 
understanding of groundwater-surface-water relationships to be used in water 
management decisions. Frequency-domain (2008 and 2009) and time-domain 
(2010) helicopter electromagnetic surveys were completed, using a unique survey 
flight line design, to collect resistivity data that can be related to lithologic information 
for refinement of groundwater model inputs.  To make the geophysical data useful for 
multidimensional groundwater models, numerical inversion is necessary to convert 
the measured data into a depth-dependent subsurface resistivity model.  This inversion 
model, in conjunction with sensitivity analysis, geological ground truth (boreholes), and 
geological interpretation, is used to characterize hydrogeologic features.  The two- and 
three- dimensional interpretation provides the groundwater modeler with a high-resolution 
hydrogeologic framework and a quantitative estimate of framework uncertainty.  This 
method of creating hydrogeologic frameworks improved the understanding of the actual 
flow path orientation by redefining the location of the paleochannels and associated 
bedrock highs. The improved models represent the hydrogeology at a level of accuracy 
not achievable using previous data sets.

Faults in the Point Reyes map area are identified on seismic-reflection data based on abrupt truncation or warping of reflections and (or) juxtaposition of reflection panels with different seismic parameters such as reflection presence, amplitude, frequency, geometry, continuity, and vertical sequence. Faults were primarily mapped by interpretation of seismic reflection profile data (see field activity S-8-09-NC). The seismic reflection profiles were collected in 2009.

Sprague River Oregon Vegetation 2000

The Sprague River drains 4090 square kilometers in south-central Oregon before flowing into the Williamson 
River and upper Klamath Lake. In cooperation with the U.S. Fish and Wildlife Service, the USGS and University 
of Oregon conducted a study to evaluate channel and floodplain processes for the 131 km of the Sprague River 
and its major tributaries, including the lower 20 km of the South Fork Sprague River, the lower 16 km of the North 
Fork Sprague River, and the lower 62 km of the Sycan River. The study involved multiple analyses, including 
assessments of historical channel change, riparian and floodplain vegetation, and surficial geology. To support 
these analyses, digital floodplain and channel maps were prepared from historic notes, maps, and aerial photos 
to depict channel and floodplain conditions at different times between 1866 and 2005. The geospatial database 
of current and historic channel and floodplain conditions will also enable evaluation of long-term trends pertaining 
to aquatic and riparian habitat conditions.

Topobathy grid representing the backshore to the nearshore at Head of the Meadow Beach, Truro from data taken during field activity 2020-015-FA on March 6 and 10, 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.
