TIFF image format of radiographs of gravity cores collected in 2008 by the U.S. Geological Survey around Puerto Rico and the U.S. Virgin Islands and accompanied by CSV and XLS files containing image lists and section information

In 2008, as a collaborative effort between Woods Hole Oceanographic Institution and the U.S. Geological Survey, 20 giant gravity cores were collected from areas surrounding Puerto Rico and the U.S. Virgin Islands. The regions sampled have had many large earthquake and landslide events, some of which are believed to have triggered tsunamis. The objective of this coring cruise, carried out aboard the National Oceanic and Atmospheric Administration research vessel Seward Johnson, was to determine the age of several substantial slope failures and seismite layers near Puerto Rico in an effort to map their temporal distribution. Data gathered from the cores collected in 2008 and 11 archive cores from the Lamont-Doherty Earth Observatory are included in this report. These data include lithologic logs, core summary sheets, x-ray fluorescence, wet-bulk density, magnetic susceptibility, grain-size analyses, radiographs, and radiocarbon age dates.

SfM Quantitative Underwater Imaging Device with 5 cameras (SQUID-5) – Field data from periodic surveys of the Florida Keys and other select shallow water environments

The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) and Processes Impacting Seafloor Change and Ecosystem Services (PISCES) projects collect underwater imagery of coral reefs and other scientifically interesting, submerged environments using the novel SfM (Structure-from-Motion) Quantitative Underwater Imaging Device with 5 cameras (SQUID-5) system. This sensor collects imagery with optimized endlap/sidelap and precise position information to create high-resolution orthomosaics, three-dimensional (3D) point clouds, and digital elevation/surface models (DEMs/DSMs) using  SfM photogrammetry methods. These products are valuable for measuring submerged topographic and ecological change, and for understanding reef vulnerability and response to disturbance events.
This is an ongoing collection of underwater imagery surveys of coral reefs and other clear water environments. Shallow water (approximately 2-10 meters [m] depth) digital imagery is acquired using the "SfM Quantitative Underwater Imaging Device with 5 cameras" (SQUID-5) towed surface sensor system. The system consists of five synchronized rigidly connected downward-looking digital cameras with overlapping views of the seafloor, along with a custom integrated survey-grade Global Navigation Satellite System (GNSS) receiver.

02031 - Geophysical Surveys of Bear Lake, Utah-Idaho, September 2002 - Chirp Seismic Tracklines (CHRPTRK)

Bear Lake is a tectonic lake that has existed for at least several hundred thousand years. The lake basin is a relatively simple half graben, a spoon-shaped depression tilted toward the main fault on the east side of the lake. The U.S. Geological Survey, in cooperation with researchers from several universities, has been studying the sediments of Bear Lake since 1996. The general purpose of this effort is to reconstruct past limnological conditions and regional climate on a range of timescales, from hundreds of years to hundreds of thousands of years. This research relates to a variety of human concerns, including water usage in the Bear River basin. Past work has included several coring operations, a seismic-reflection survey, sediment-trap deployments, a barge-mounted drilling operation with the GLAD800 drill rig, and a variety of other studies.
The objectives of the September, 2002 operations, preliminarily reported here, were (1) to compile a detailed bathymetric map of the lake using swath-mapping techniques, in order to provide baseline data for a variety of applications and studies, and (2) to complete a sidescan-sonar survey of the lake, providing a nearly complete acoustic image of the lake floor. Limited amounts of subbottom acoustic-reflection data (chirp) were also collected, along with samples of lake-floor sediments representative of different kinds of backscatter patterns. These surveys followed an earlier subbottom acoustic-reflection survey (1997), using boomer and 3.5 kHz systems (S. M. Colman, unpublished data).

National-scale, remotely sensed lake trophic status 1984-2020

Lake trophic status is a key water quality property that integrates a lake's physical, chemical, and biological processes. Despite the importance of trophic status as a gauge of lake water quality, standardized and machine readable observations are uncommon. Remote sensing presents an opportunity to detect and analyze lake trophic status with reproducible, robust methods across time and space. We used Landsat surface reflectance and lake morphometric data to create the first compendium of lake trophic status for more than 56,000 lakes of at least 10 ha in size throughout the contiguous United States from 1984 through 2020. The dataset was constructed with FAIR data principles (Findable, Accessible, Interoperable, and Reproducible) in mind, where data are publicly available, relational keys from parent datasets are retained, and all data wrangling and modeling routines are scripted for future reuse. Together, this resource offers critical data to address basic and applied research questions about lake water quality at a suite of spatial and temporal scales.

Microbial Ecology of the Floridan Aquifer near Okeechobee, FL: Uptake and Inactivation Data

This metadata record describes the microbial uptake of nutrients by native planktonic and biofilm-associated bacteria and the inactivation of E. coli, MS2 bacteriophage, polio virus and Cryptosporidium parvum in the Upper Floridan Aquifer (approximately 1,000 feet below land surface) in the Okeechobee, Florida area. Groundwater samples were collected or accessed via the use of a mesocosm between 2018 and 2020 from a South Florida Water Management District (SFWMD) monitoring well installed at the Kissimmee River Aquifer Storage and Recovery (ASR) facility, which is located at the discharge point of the Kissimmee River into Lake Okeechobee.

Digital data sets that describe aquifer characteristics of the Elk City aquifer in western Oklahoma

This data set consists of digitized water-level elevation
contours for the Elk City aquifer in western Oklahoma. The
aquifer covers an area of approximately 193,000 acres and
supplies ground water for irrigation, domestic, and industrial
purposes in Beckham, Custer, Roger Mills, and Washita Counties
along the divide between the Washita and Red River basins.
The Elk City aquifer consists of the Elk City Sandstone and
overlying terrace deposits, made up of clay, silt, sand and
gravel, and dune sands in the eastern part and sand and gravel
of the Ogallala Formation (or High Plains aquifer) in the
western part of the aquifer. The Elk City aquifer is unconfined
and composed of very friable sandstone, lightly cemented with
clay, calcite, gypsum, or iron oxide. Most of the grains are
fine-sized quartz but the grain size ranges from clay to cobble
in the aquifer. The Doxey Shale underlies the Elk City aquifer
and acts as a confining unit, restricting the downward movement
of ground water.
Water-level elevations were measured in July 1973 and ranged
from about 2,200 feet above sea level at the northwestern edge
of the aquifer to about 1,700 feet above sea level at the
southeastern edge of the aquifer. The water-level elevation
contours were digitized from a photocopy of a paper map from a
ground-water modeling thesis. The source map was published at a
scale of 1:63,360.

Assessing the Effectiveness of Nourishment in Decadal Barrier Island Morphological Resilience: Model Inputs and Outputs (Storm_152_Elevations_N)

Using version 5527 of the XBeach numerical model (Roelvink and others, 2009), barrier island morphological change was simulated at Dauphin Island, Alabama (AL), for a 30-year forecast of multiple storms and sea level rise, considering scenarios of no-action and beach and dune nourishment as described in Passeri and others (2021). The two-dimensional XBeach model can be applied to barrier islands to solve for time-dependent topography and bathymetry. The XBeach model setup requires the input of topographic and bathymetric elevations at each grid cell. Model inputs and outputs in the form of topography and bathymetry at each grid cell are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2021).

MODFLOW-2005 data sets for simulation of Groundwater-Flow Budget for the Lower Apalachicola-Chattahoochee-Flint River Basin in Southwestern Georgia and Parts of Florida and Alabama, 2008-12

As part of the National Water Census program in the Apalachicola-Chattahoochee-Flint (ACF) 
River Basin, the U.S. Geological Survey evaluated the groundwater budget of the lower ACF, 
with particular emphasis on recharge, characterizing the spatial and temporal relation between 
surface water and groundwater, and groundwater pumping. To evaluate the hydrologic budget of 
the lower ACF River Basin, a groundwater-flow model, constructed using MODFLOW-2005, was 
developed for the Upper Floridan aquifer and overlying semiconfining unit for 2008–12. Model input 
included temporally and spatially variable specified recharge, estimated using a preliminary version 
of a Precipitation-Runoff Modeling System (PRMS) model for the ACF River Basin, and pumping, 
partly estimated on the basis of measured agricultural pumping rates in Georgia. The model was 
calibrated to measured groundwater levels, and base flows which were estimated using hydrograph 
separation. The simulated groundwater flow budget resulted in a net cumulative loss in groundwater 
storage during the study period. Spatial variability in simulated hydrologic budgets for eight subbasins 
was attributed to such factors as soil storage capacity, Lake Seminole impoundment, and the 
presence of in-channel springs. The model simulated a net storage loss for all the subbasins. The 
model is limited by its conceptualization, the data used to represent and calibrate the model, and 
the mathematical representation of the system; therefore, any interpretations should be considered 
in light of these limitations. In spite of these limitations, the model provides insight regarding water 
availability in the lower ACF River Basin. 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/sir20175141).

Digital Shoreline Analysis System version 4.3 shoreline intersection points used to calculate short-term (End Point Rate) shoreline change statistics for the Boston coastal region from Carson Beach in South Boston to Weymouth River, including the Boston Harbor Islands (Boston_intersects_STepr.shp)

Due to continued coastal population growth and increased threats of erosion, current data on trends and rates of shoreline movement are required to inform shoreline and floodplain management. The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Office of Coastal Zone Management, has compiled reliable historical shoreline data along open-facing sections of the Massachusetts coast under the Massachusetts Shoreline Change Mapping and Analysis Project 2013 Update. Two oceanfront shorelines for Massachusetts (approximately 1,800 km in total length) were (1) delineated using 2008/09 color aerial orthoimagery, and (2) extracted from topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. The new shorelines were integrated with existing Massachusetts Office of Coastal Zone Management and USGS historical shoreline data in order to compute long- and short-term rates using the latest version of the Digital Shoreline Analysis System (DSAS).

2010-012-FA_MOSAIC_GE.tif - Composite sidescan-sonar mosaic collected by the U.S. Geological Survey in Woods Hole, MA  offshore of the Gulf Islands, MS, 2010 (UTM Zone 16N GeoTIFF)

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. More information on the field work can be accessed from the Woods Hole Coastal and Marine Science Center Field Activity webpage https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-012-FA or the St. Petersburg Coastal and Marine Geology InfoBank https://walrus.wr.usgs.gov/infobank/m/m210gm/html/m-2-10-gm.meta.html.

Umpqua River Oregon Active Channel 1939

The Umpqua River drains 12,103 square kilometers (4,673 square miles) in southwest Oregon before flowing into 
the Pacific Ocean at Winchester Bay near the city of Reedsport. In cooperation with the Portland District of the 
U.S. Army Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage along the 
downstream alluvial reaches of the North and South Umpqua Rivers and the entire mainstem Umpqua River. 
This includes the lower 46.8 kilometers (29.1 miles) of the North Umpqua River and the lower 122.6 kilometers 
(76.2 miles) of the South Umpqua River. 
	 
The Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical 
channel change and estimation of a sediment budget. To support these analyses, digital channel maps were
 produced to depict channel and floodplain conditions along the Umpqua River system from different time periods.
		
GIS layers defining the active channel of the Umpqua River system were developed for three time periods: 
1939, 1967, and 2005. For the South Umpqua River and the 19 kilometers (12 miles) of the mainstem 
Umpqua River downstream from the confluence of the North and South Umpqua Rivers, GIS layers were 
also developed for the time periods 1994, 2000, and 2009.
		
For this project, the active channel was defined as area typically inundated during annual high flows, and 
includes the low-flow channel as well as side channels, islands, and channel-flanking gravel bars. The 
active channel datasets were developed by digitizing from aerial photographs. Aerial photographs from 
1939 and 1967 were scanned, rectified, and mosaiced for this project. Digital orthophotographs from 
1994, 2000, 2005, and 2009 are publicly available (See metadata for each photograph set for more 
information on the rectification process and resolution of each dataset). Although our study area 
encompasses the Umpqua River and lower reaches of the North and South Umpqua Rivers, the 
extent of each dataset depended upon the underlying aerial photographs; for example, the 1967 
photographs extend only as far downstream as floodplain kilometer 7, whereas the 1939 and 2005 
datasets extend to the mouth of the Umpqua River at the Pacific Ocean.
