Description

This dataset is an aggregation of county-level tillage practices to the 8-digit hydrologic unit watershed. The original county-level data were collected by the Conservation Technology Information Center (CTIC) and is a proprietary dataset. The CTIC collects tillage data by conducting surveys about tillage systems for all counties in the United States. Watershed aggregations were done by overlying the 8-digit HUC polygons with a raster of county boundaries and a raster of the 2001 National Land Cover Data for land use 82 (cultivated land) to derive a county/land-use area weighting factor. The weighting factor was then applied to the county-level tillage data for the counties within each 8-digit HUC and summed to yield the total acreage of each tillage type within each 8-digit HUC watershed. Tillage systems include three types of conservation tillage (no-till, ridge-till, and mulch-till), reduced tillage, and intensive tillage. Total planted acreage for each tillage practice for each crop grown is reported to the CTIC. The dataset includes total planted acreage by tillage type for selected crops (corn, cotton, grain sorghum, soybeans, fallow, forage, newly established permanent pasture, spring and fall seeded small grains, and "other" crops) for 1989-2004. The CTIC did not collect data nationwide for 1999, 2001, and 2003. In addition, data were not collected for all counties every year. Missing data are coded with -9999. The companion WBDHUC8 geospatial dataset is available online: http://water.usgs.gov/lookup/getspatial?wbdhuc8.xml .

Description

Bathymetry for Bogue Sound was derived from eleven surveys containing52,366 soundings. Two older, overlapping, less accurate surveys wereentirely omitted. The overlap from one older, less accurate surveywas omitted before tinning the data. The average separation betweensoundings was 72 meters. Surveys dating from 1876 to 1953 coveredthe east and west portions of the sound. Surveys from 1974 coveredthe center portion of the sound. The total range of sounding datawas 0.9 to -17.1 meters at mean low water. Mean high water valuesbetween 0.5 to 1.0 meters were assigned to the shoreline. Onepoint that was not consistent with the surrounding data was removedprior to tinning. DEM grid values outside the shoreline (on land)were assigned null values (-32676).Bogue Sound has six 7.5 minute DEMs and two one degree DEMs. The 1degree DEMs were generated from the higher resolution 7.5 minute DEMswhich covered the estuary. A Digital Elevation Model (DEM) contains aseries of elevations ordered from south to north with the order ofthe columns from west to east. The DEM is formatted as one ASCIIheader record (A- record), followed by a series of profile records(B- records) each of which include a short B-record header followedby a series of ASCII integer elevations (typically in units of 1centimeter) per each profile. The last physical record of the DEM isan accuracy record (C-record).The 7.5-minute DEM (30- by 30-m data spacing) is cast on theUniversal Transverse Mercator (UTM) projection. It provides coveragein 7.5- by 7.5-minute blocks. Each product provides the samecoverage as a standard USGS 7.5-minute quadrangle but the DEMcontains over edge data. Coverage is available for many estuaries ofthe contiguous United States but is not complete.

Description

NASA seeks advanced high strength and toughness composite materials with the highest microcrack resistance at cryogenic temperatures suitable for use in fuel containment of liquid oxygen, hydrogen, and methane. Nanotrons Corporation, in collaboration with Prof. Bungki Kim at NSF nanomanufacturing research center in University of Massachusetts Lowell, proposes to develop lightweight functionalized graphene sheets-polymer nanocomposite materials for advanced composite cryotanks. By uniformly dispersing high performance functionalized graphene sheets through novel polymer matrix the new lightweight nanocomposite will be fabricated and should exhibit significantly increase resin strength and modulus and reduce coefficient of thermal expansion of polymer resin. The resultant nanocomposite material can much increase the resistance to microcracking at cryogenic temperature in ways it has never done before. The new composite materials also provide additional advantages in forming an impermeable barrier to gas and liquid molecules ideal for fuel tanks. Nanotrons' proposed new multifunctional nanocomposite based carbon fiber reinforced polymer composite cryotanks will replace the currently used aluminum-lithium cryotanks providing significant weight savings and can be economically scaled-up for manufacturing. Phase I will demonstrate the feasibility of our approach.

Description

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).

Description

Rocket plume impingement may cause significant damage and contaminate co-landed spacecraft and surrounding habitat structures during Lunar landing operations. Under this proposed SBIR program, CFDRC and the University of Florida will develop an innovative high-fidelity simulation system for predicting surface erosion and debris transport caused by rocket plume impingement on lunar surface. This simulation system will combine 1) a unified continuum-rarefied flow solver capable of simulating plume impingement flow in lunar vacuum, 2) granular flow solid-fluid interaction technology for developing lunar soil grain erosion and debris particle release mechanism models, and 3) particle tracking tools to simulate debris kinetics, dispersion and contamination after liberation. In Phase I, the plume stagnation layer flow conditions at the soil surface will be modeled and computed. The solid-fluid interaction physics in the soil layer in response to this surface flow environment will be simulated and a generalized soil erosion model will be derived. The erosion model will then serve to prescribe debris mass and initial conditions for the debris-tracking module embedded in the flow solver. In Phase II, the individual modules will be combined into a single simulation system. The simulation system will be essential for predicting the severity and range of dust and debris transport and for designing lunar settlement layout, dust and debris impact mitigation measures. He will spend at least 35 % of his time on this project and his commitment to other projects is less than 50 %.

Description

Fault to Failure Progression (FFP) signature modeling and processing is a new method for applying condition-based signal data to detect degradation, to identify fault modes, and to produce system estimates for State of Health (SoH) and Remaining Useful Life (RUL). The base technology has been applied for prognostic purposes for various government-sponsored programs, but FFP signature modeling and processing has not been applied for the area of Fault Management, nor does it include such features as fault dictionaries, lookup tables, and management algorithms. The technology includes Ridgetop-designed and developed algorithms to do the following: (1) perform Kalman Filtering to reduce noise; (2) transform sensor signal data to reveal underlying (hidden) FFP signatures; (3) normalize units-of-measure dependent signal data into dimensionless FFP signatures to facilitate re-use and reduce the time to characterize and define new FFP signatures; (4) define and use model definitions that reduce memory requirements and support fast and accurate processing and calculations; (5) two forms of trajectory curve characterization, both straight-line and curvilinear; (6) a fast yet accurate, graphics-based mathematical routine to adapt an FFP model to received data; (7) amplitude and time updates similar to Extended Kalman Filtering to estimate how long it will take an adapted FFP model to reach a defined failure threshold; and (8) produce SoH and RUL estimates that rapidly converge to the estimated time-to-failure (TTF) solution. The FFP signature modeling and processing will include additional innovation to support FM to minimize application-specific programming, those include algorithms to simplify fault identification and isolation.

Description

These data represent the interpretations from borehole electric (resistivity) logs from oil and gas wells and lithologic logs from nearby water wells. These interpretations were used to build the hydrogeologic framework in the Williston structural basin. The resistivity logs were used to identify the hydrogeologic units (fig. 3A of SIR 2014-5047) and to quantify the vertical detailed lithology (thickness of sand, coal, gravel, silt, and shale) in the oil and gas exploration boreholes.

Description

The MAI-400SS Space Sextant is a precision attitude determination and control system for CubeSats and Nanosats. The MAI-400SS enables future CubeSat missions with precision fine pointing (0.1deg) and dynamic slewing as will be required for imaging operations of ground targets. A flight control computer, 2 Star Trackers, 3 reaction wheels and 3 electromagnets are incorporated in a 4" x 4" x 3" (3/4U) CubeSat sized module. The system is based on the highly successful MAI-400 miniADACS and extends its performance capability to the 0.1deg range by incorporation of 2 star cameras and attitude determination software. Phase I developed the software algorithms and prototyped the star cameras and electronics. Phase II consists of a development program culminating with a system at TRL 7. The technology is significant because it extends the capability of current low cost Nanosats to tactical imaging and other missions requiring fine pointing and dynamic retargeting, missions hitherto restricted to large and expensive spacecraft. The MAI-400SS will facilitate rapid development of low cost satellites by providing a turnkey system which would be capable of determining and controlling spacecraft attitude automatically; simplifying operations and enabling rapid mission development as envisioned by ORS.

Description

An area's economic and social characteristics have significant effects on its development and need for various types of public programs. To provide policy-relevant information about diverse county conditions to policymakers, public officials, and researchers, ERS has developed a set of county-level typology codes that captures differences in economic and social characteristics. The 2004 County Typology codes classify all U.S. counties according to six non-overlapping categories of economic dependence and seven overlapping categories of policy-relevant themes. The economic types include farming, mining, manufacturing, services, Federal/State government, and unspecialized counties. The policy types include housing stress, low education, low employment, persistent poverty, population loss, nonmetro recreation, and retirement destination. In addition, a code identifying counties with persistent child poverty is available. An update of the County Typology codes is planned for 2014.

Description

The National High Altitude Photography (NHAP) program, which was operated from 1980-1989, was coordinated by the U.S. Geological Survey as an interagency project to eliminate duplicate photography in various Government programs. The aim of the program was to cover the 48 conterminous states over a 5-year span. In the NHAP program, black-and-white and color-infrared aerial photographs were obtained on 9-inch film from an altitude of 40,000 feet above mean terrain elevation and are centered over USGS 7.5-minute quadrangles. The color-infrared photographs are at a scale of 1:58,000 (1 inch equals about .9 miles), and the black-and-white photographs are at a scale of 1:80,000 (1 inch equals about 1.26 miles). All NHAP flights where flown in a North to South direction. These photographs are offered as digital images.

Description

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).The file is georeferenced to earth's surface using the State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.
