Digital Shoreline Analysis System version 4.3 transects and short-term (1970-2009) linear regression shoreline change statistics for the South Shore coastal region from Hewitts Cove in Hingham to the Cape Cod Canal in Sandwich (SouthShore_transects_rates_STlr.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) 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).

1992 County Pesticide Use Estimates for 200 Compounds

This dataset includes information for 200 pesticides on the average amount
(pounds) applied to 87 agricultural crops and the acres of crops treated for
counties within the conterminous United States.  These data were derived by 
combining published state pesticide use coefficients published by the
National Center for Food and Agricultural Policy (NCFAP) and county
harvested crop acres available from the 1992 Census of Agriculture.
A description of the methods used to develop the county database
is published in USGS OFR 00-250, "Method for Estimating Pesticide Use" 
and is available online from: http://pubs.er.usgs.gov/pubs/ofr/ofr00250.
Maps showing the geographic distribution of use patterns for 199
compounds (BT was not mapped) area available from http://ca.water.usgs.gov/pnsp/.
The pesticide use estimates contained in this file represent average
usage patterns for the years 1990-1993 and do not represent a specific
year.  The key limitations of the data include the following:
(1) state use coefficients represent an average for the entire
state and consequently do not reflect the local variability of
pesticide management practices found within states and counties,
(2) pesticide use estimates are not for a specific year, but
represent typical use patterns for a four year period, (3) state
pesticide use coefficients many not have been available for all states
where a pesticide may have been applied to agricultural land,
and therefore, are not included, and (4) the county crop acreage
use to estimate county pesticide use is from the 1992 Census of
Agriculture and may not represent all crop acreage because of
Census nondisclosure rules.

Raw continuous resistivity profiling data collected in Greenwich Bay, Rhode Island, on May 15, 2009, on U.S. Geological Survey Field Activity 2009-021-FA

As part of a larger investigation to understand groundwater-surface water interactions in Greenwich Bay, Rhode Island, a geophysical survey was conducted from a small research boat on 14-15 May 2009. The specific research objective was to gain an improved understanding of the role of direct groundwater discharge in delivery of excess nitrogen to the bay, which may have contributed to the development of low-oxygen conditions in waters of the bay and associated fish kills. Data collected in this survey included digital navigation information, continuous resistivity profiling (CRP) data, and point salinity measurements. The CRP method is a survey and data processing approach that is sensitive to differences in electrical properties of surface water and underlying porewater in sediments that have contrasting salinities. During the survey, Greenwich Bay salinity was approximately 27 ppm, so surface water would be expected to have low electrical resistivity (high conductivity), and any areas of active groundwater discharge from less salty aquifer sources would yield relatively higher resistivity values. This survey is identified as field activity 09021 (also referenced as 2009-021-FA) by the U.S. Geological Survey, Woods Hole, Massachusetts, and additional information is available from: https://cmgds.marine.usgs.gov/fan_info.php?fan=2009-021-FA.

LANDFIRE Remap 2016 Public Model Ready Events AK

The LANDFIRE (LF) Remap Public Model Ready Events feature class is a compilation of natural disturbance and vegetation/fuel treatment events that occurred between 1999 and 2016. The Public Model Ready Events feature class includes a subset of the full suite of data that were used in the production of LANDFIRE 2008 Refresh (LF 1.1.0), LANDFIRE 2010 (LF 1.2.0), LANDFIRE 2012 (LF 1.3.0), LANDFIRE 2014 (LF 1.4.0), and LANDFIRE Remap (LF 2.0.0) program deliverables. According to agreements between LANDFIRE and its data contributors, certain proprietary or otherwise sensitive data were removed to create this publicly available version. For more information about the data sources included and excluded from this release, please consult the Source_Code look up table found at: http://www.landfire.gov/publicevents.php. The data were collected from disparate sources including federal, state, and local, and private organizations, and systematically converted to the standard LANDFIRE Events format. The data in the Public Model Ready Events feature class were analyzed to eliminate geospatial or information content errors. The Public Model Ready Events feature class was reduced to only one unique event per year per location. In order to produce the Model Ready layer, a series of topologies were created with the Raw Events data to identify areas of overlap between polygons within the same year. The topology errors were corrected using a standard hierarchy of LANDFIRE Event types, which were organized so the events with the greatest impact on vegetation and/or fuels composition and structure were ranked highest. To correct topology errors, polygons with lower ranked events were merged into polygons with higher ranked events where they overlapped. When there were multiple perimeters for the same event one perimeter was chosen. The selected perimeter was not necessarily from a public data set so the Public Model Ready Events feature class may be missing information on events that appear in the Public Raw Events feature class. The result is a layer which contains only one event per year for a location. Reforestation (seeding and planting) events were analyzed further to remove all but the most recent event at each location. Point derived polygons and polygons less than 0.02 acres in size were removed.

Polygon shapefile of the interpretation of the seabed geologic substrates in quadrangle 6 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts based on data collected by the U.S. Geological Survey from 1993-2004 (Geographic, NAD 83)

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration's National Marine Sanctuary Program, has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary region since 1993. The area is approximately 3,700 square kilometers (km2) and is subdivided into 18 quadrangles. Seven maps, at a scale of 1:25,000, of quadrangle 6 (211 km2) depict seabed topography, backscatter, ruggedness, geology, substrate mobility, mud content, and areas dominated by fine-grained or coarse-grained sand. Interpretations of bathymetric and seabed backscatter imagery, photographs, video, and grain-size analyses were used to create the geology-based maps. In all, data from 420 stations were analyzed, including sediment samples from 325 locations. The seabed geology map shows the distribution of 10 substrate types ranging from boulder ridges to immobile, muddy sand to mobile, rippled sand. Substrate types are defined on the basis of sediment grain-size composition, surficial morphology, sediment layering, and the mobility or immobility of substrate surfaces. This map series is intended to portray the major geological elements (substrates, features, processes) of environments within quadrangle 6. Additionally, these maps will be the basis for the study of the ecological requirements of invertebrate and vertebrate species that utilize these substrates and guide seabed management in the region.

GAK_Q39.TIF - Gulf of Alaska U.S. EEZ GLORIA sidescan-sonar data mosaic (9 of 30) (LCC, 50 m, WGS84)

GLORIA data for the Gulf of Alaska Exclusive Economic Zone (EEZ) were acquired during five cruises over a four year period. The first cruise conducted in 1986 (F-1-86-GA) surveyed an area of the north-central mosaic area and covered an area of approximately 40,000 square kilometers (sq km). The second two cruises (F-8-88-AA, F-9-88-WG) were conducted in 1988. One of the 1988 cruises (F-8-88-AA) focused on a survey of the Aleutian Arc. The eastern most portion of that survey extended outside of the Aleutian Arc survey area and covered an area of approximately 52,000 square kilometers (sq km) of seafloor on the western edge of the Gulf of Alaska. The final two cruises (F-6-89-GA, F-7-89-EG) were completed in 1989. 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. Thirty digital mosaics with a 50-meter pixel resolution were completed for the region.

Chirp Seismic Survey Tracklines - Lake Mead 2000

Lake Mead is a large interstate reservoir located in the Mojave Desert of southeastern Nevada and northwestern Arizona. It was impounded in 1935 by the construction of Hoover Dam and is one of a series of multi-purpose reservoirs on the Colorado River. The lake extends 183 km from the mouth of the Grand Canyon to Black Canyon, the site of Hoover Dam, and provides water for residential, commercial, industrial, recreational, and other non-agricultural users in communities across the southwestern United States. Extensive research has been conducted on Lake Mead, but a majority of the studies have involved determining levels of anthropogenic contaminants such as synthetic organic compounds, heavy metals and dissolved ions, furans/dioxins, and nutrient loading in lake water, sediment, and biota (Preissler, et al., 1998; Bevans et al, 1996; Bevans et al., 1998; Covay and Leiker, 1998; LaBounty and Horn, 1997; Paulson, 1981). By contrast, little work has focused on the sediments in the lake and the processes of deposition (Gould, 1951). To address these questions, sidescan-sonar imagery and high-resolution seismic-reflection profiles were collected throughout Lake Mead by the USGS in cooperation with researchers from University of Nevada Las Vegas (UNLV). These data allow a detailed mapping of the surficial geology and the distribution and thickness of sediment that has accumulated in the lake since the completion of Hoover Dam. Results indicate that the accumulation of post-impoundment sediment is primarily restricted to former river and stream beds that are now submerged below the lake while the margins of the lake appear to be devoid of post-impoundment sediment. The sediment cover along the original Colorado River bed is continuous and is typically greater than 10 m thick through much of its length. Sediment thickness in some areas exceeds 35 m while the smaller tributary valleys typically are filled with less than 4 m of sediment. Away from the river beds that are now covered with post-impoundment sediment, pre-impoundment alluvial deposits and rock outcrops are still exposed on the lake floor.
