Processed Continuous Resistivity Profiles from Cape Cod National Seashore, Feb. 28, 2006

Continuous resistivity profiling (CRP) surveys were conducted at Cape Cod National Seashore in 2004 and 2006 in order to test hypotheses about groundwater flow under and into estuaries and the Atlantic Ocean. Coastal resource managers here and elsewhere are concerned about nutrients that are entering coastal waters via submarine groundwater discharge, which are contributing to eutrophication and harmful algal blooms. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to differences in salinity of submarine ground water. The 2004 and 2006 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software.

Estimates of agricultural-chemical use in counties in the conterminous United States as reported in the 1987 Census of Agriculture

This coverage contains estimates of agricultural-chemical use in counties in the conterminous 
United States as reported in the 1987 Census of Agriculture (U.S. Department of Commerce, 1989a). 
Agricultural-chemical use data are reported as either acres on which used, tons, or as a percentage of 
county area.  Agricultural-chemical use estimates were generated from surveys of all farms where $1,000 
or more of agricultural products were sold, or normally would have been sold, during the census year.
		
Most of the attributes summarized represent 1987 data, but some information from the 1982 Census of 
Agriculture also was included.
		
The polygons representing county boundaries in the conterminous United States, as well as lakes, 
estuaries, and other nonland-area features were derived from the Digital Line Graph (DLG) files 
representing the 1:2,000,000-scale map in the National Atlas of the United States (1970).

Sediment grain size data from samples collected offshore Oceanside, southern California during field activity 2017-686-FA from 2017-10-23 to 2017-10-31

This section of the data release contains grain-size analysis of twenty-six seafloor surface grab samples that were collected aboard the R/V Snavely in 2017 on U.S. Geological Survey cruise 2017-686-FA offshore Oceanside, southern California. The samples were collected at strategic locations along the same transects as seismic-reflection lines oriented to assess sand and gravel resources in Federal and State waters for potential use in future beach nourishment projects along stretches of the coast where critical erosion hotspots have been identified. Samples were collected at 23 locations using a Van Veen sediment sampler along 4 shore-perpendicular transects spaced 5 to 9 km apart, aligned with previously collected seismic profile lines, at depths ranging from about 20 to 80 m. One sample on the outer shelf (BSS-06) was collected to evaluate an area of suspected sand occurrence. Two duplicate samples were collected at one location (BSS-08) in order to evaluate local sample variability.

Navigation and environmental data from R/V Weatherbird II for the West Florida Shelf: USGS Cruise 11BHM03

The United States Geological Survey (USGS) is conducting a study on the effects of climate change on ocean acidification within the Gulf of Mexico; dealing specifically with the effect of ocean acidification on marine organisms and habitats. To investigate this, the USGS participated in two cruises in the West Florida Shelf and northern Gulf of Mexico regions aboard the R/V Weatherbird II, a ship of opportunity lead by Dr. Kendra Daly, of the University of South Florida (USF). The cruises occurred September 20 - 28 and November 2 - 4, 2011. Both left from and returned to Saint Petersburg, Florida, but followed different routes (see Trackline). On both cruises the USGS collected data pertaining to pH, dissolved inorganic carbon (DIC), and total alkalinity in discrete samples. Discrete surface samples were taken during transit approximatly hourly on both cruises, 95 in September were collected over a span of 2127 km, and 7 over a trackline of 732 km line on the November cruise. Along with the surface samples, another set of samples were taken at various depths at stations; 27 in September at four stations and 15 in November at five stations. In addition to the discrete samples flow-through data was also collected on both cruises in a variety of forms. Surface CTD data was collected every five minutes which includes temperature, salinity, and pH. In addition, two more flow-through instruments were setup on both cruises that recorded pH and CO2 every 15 minutes. Corroborating the USGS data is the vertical CTD profiles collected by USF, using the following sensors: CTD, oxygen, chlorophyll fluorescence, optical backscatter, and transmissometer. Additionally, discrete depth samples for nutrients, chlorophyll, and particulate organic carbon/nitrogen were collected.

Faults--Offshore of San Francisco Map Area, California

This part of DS 781 presents data for faults for the geologic and geomorphic map of the Offshore San Francisco map area, California. The vector data file is included in "Faults_OffshoreSanFrancisco.zip," which is accessible from https://pubs.usgs.gov/ds/781/OffshoreSanFrancisco/data_catalog_OffshoreSanFrancisco.html. These data accompany the pamphlet and map sheets of Cochrane, G.R., Johnson, S.Y., Dartnell, P., Greene, H.G., Erdey, M.D., Golden, N.E., Hartwell, S.R., Endris, C.A., Manson, M.W., Sliter, R.W., Kvitek, R.G., Watt, J.T., Ross, S.L., and Bruns, T.R.

Faults in the Offshore of San Francisco 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 activities S-15-10-NC and F-2-07-NC).  The seismic reflection profiles were collected between 2007 and 2010.

Digital Shoreline Analysis System version 4.1 Transects with Short-Term Rate Calculations for the Greater Boston region from the southern side of Cape Ann, Massachusetts to Sandy Neck Beach in Sandwich, Massachusetts (GreaterBoston_ST.shp)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

Airborne geophysical survey: SE Bethel Basin '94

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field intensity values and location. In surveys such as this one where the data were originally collected in digital form and not digitized from contour maps, the information we provide typically includes latitude, longitude, magnetic anomaly in nanoTeslas, and intermediate values used to derive the magnetic anomaly such as total magnetic field.

Mitochondrial sequence data for Peninsula Leaf-toed Geckos from southern California, USA (2018-2019)

We amplifed and sequenced a 386 base-pair region of the mitochondrial protein-coding cytochrome c oxidase subunit I (COI) gene to  analyze genetic diversity from a new population of Peninsula Leaf-toed Gecko (Phyllodactylus nocticolus) in the Tranverse Range of southern California, USA. We compare these data with genetic data gathered from more southern populations of P. nocticolus from the Peninsular Ranges and determined that genetic diversity from the Tranverse Range population was distinct. These results provide support for a naturally occurring population in the Transverse Range of southern California.

National Land Cover Database 2001 (NLCD01) Tree Canopy Layer Tile 2, Northeast United States: CNPY01_2

This 30-meter resolution data set represents the tree canopy layer for the conterminous 
United States for the 2001 time period. The data have been arranged into four tiles to 
facilitate timely display and manipulation within a Geographic Information System, 
browse graphic: nlcd01-partition.jpg
		
The National Land Cover Data Set for 2001 was produced through a cooperative project 
conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC 
Consortium is a partnership of Federal agencies (www.mrlc.gov), consisting of the U.S. 
Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), 
the U.S. Environmental Protection Agency (USEPA), the U.S. Department of Agriculture 
(USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish 
and Wildlife Service (USFWS), the Bureau of Land Management (BLM), and the USDA 
Natural Resources Conservation Service (NRCS). One of the primary goals of the project 
is to generate a current, consistent, seamless, and accurate National Land Cover Database 
(NLCD) circa 2001 for the United States at medium spatial resolution. For a detailed definition 
and discussion on MRLC and the NLCD 2001 products, refer to Homer and others (2004) 
and http://www.mrlc.gov/mrlc2k.asp.
		
The NLCD 2001 was created by partitioning the United States into mapping-zones. A total 
of 68 mapping-zones browse graphic: nlcd01-mappingzones.jpg were delineated within the 
conterminous United States based on ecoregion and geographical characteristics, 
edge-matching features, and the size requirement of Landsat mosaics. Mapping-zones 
encompass the whole or parts of several states. Questions about the NLCD mapping 
zones can be directed to the NLCD 2001 Land Cover Mapping Team at the USGS/EROS, 
Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.

Globorotalia truncatulinoides Sediment Trap Data in the Gulf of Mexico

Modern observations of planktic foraminifera from sediment trap studies help to constrain the regional ecology of paleoceanographically valuable species. Results from a weekly-resolved sediment trap time series (2008–2014) in the northern Gulf of Mexico demonstrate that 92% of Globorotalia truncatulinoides flux occurs in winter (January, February, and March), and that encrusted and non-encrusted individuals represent calcification in distinct depth habitats. Individual foraminiferal analysis (IFA) of G. truncatulinoides tests were used to investigate differences in the elemental Magnesium/Calcium (Mg/Ca) and isotopic composition (δ18O and δ13C) of the encrusted and non-encrusted ontogenetic forms of G. truncatulinoides, and to estimate their calcification depth in the northern Gulf of Mexico. Estimates show that non-encrusted and encrusted G. truncatulinoides have mean calcification depths of 66 ± 9 meters and 393 ± 83 meters, respectively. The Mg/Ca-calcification temperature relationship was validated for G. truncatulinoides and demonstrated that the δ18O and Mg/Ca of the non-encrusted form is a suitable proxy for winter surface mixed layer conditions in the Gulf of Mexico. Care should be taken not to combine encrusted and non-encrusted individuals of G. truncatulinoides for down core paleoceanographic studies. For further information regarding data collection and/or processing methods as well as the associated published manuscript refer to Reynolds and others (2018b).

DS-777 Spatial Location of Stream Elevations for the Northern High Plains Groundwater-Flow Model in Parts of Colorado, Kansas, Nebraska, South Dakota, and Wyoming

This data set is one of many developed in support of The High Plains Groundwater Availability Project 
and the USGS Data Series Report: Geodatabase Compilation of Hydrogeologic, Remote Sensing, and 
Water-Budget-Component data for the High Plains aquifer, 2011 (DS 777). 
		
This dataset contains point vector data from the National Hydrography Dataset Plus (NHD+) 1:100,000 
stream polyline data converted into points and attributed with elevation values in feet above sea level.
Streams were initially included if they had a mean estimated base flow of more than 10 cubic feet per 
second (based on streamflow data from long-term streamflow-gaging stations operated by the USGS 
or the Nebraska Department of Natural Resources). The stream network then was expanded to include 
selected streams that were deemed hydrogeologically important but had a mean estimated base flow 
of less than 10 cubic feet per second.

Base of aquifer contours for the Northern High Plains aquifer

Several pre-existing datasets that characterize portions of the 
Northern High Plains aquifer base were merged together in order 
to define the entire base of the Northern High Plains aquifer. This 
digital dataset consists of the aquifer base elevation contours 
(100-foot contour interval) for the northern portion of the High Plains 
aquifer in the central United States. The boundaries were chosen 
to simplify boundary conditions for a computer simulation model 
being used for a hydrologic study of the Northern High Plains.
