Description

The Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) has performed a coastal survey along the Gulf of Mexico in the summer of 2005. The data types collected include bathymetry and topographic lidar point data, and true color imagery. The collection effort follows the coastline and extends 500m inland and 1000m offshore or to laser extinction, whichever comes first. Topographic lidar is collected with 200% coverage, yielding a nominal 1m x 1m post-spacing. Where water conditions permit, the bathymetry lidar data will have a nominal post spacing of 4m x 4m. The true color imagery will have a pixel size approximately 35cm. The final data will be tied to horizontal positions, provided in decimal degrees of latitude and longitude, and are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID03 model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88).

Description

The liberation of particles induced by rocket plume flow from spacecraft landing on unprepared regolith of the Moon, Mars, and other destinations poses high mission risks for robotic and human exploration activities. This process occurs in a combination of "extreme environments" that combine low gravity, little or no atmosphere, rocket exhaust gas flow that is supersonic and partially rarefied, and unusual geological and mechanical properties of highly irregular surface regolith. CFDRC and the University of Florida will deliver unique plume driven erosion simulation software for such environments by combining novel granular physics simulation modules developed by UF with multi-phase gas-granular flow simulation software developed by CFDRC. Granular flow constitutive models, formulated through first-principle 3-D Discrete Element Method particle kinetics and implemented in an efficient Eulerian gas-granular flow solver are the foundation of this software. The fidelity of these simulations will be advanced towards simulating particle compositions with broad shape and size variations. Novel particle kinetics modeling concepts will be applied to formulate granular flow physics models for both, realistic irregular particle shapes and dispersed particle size distributions. Phase I demonstrated the successful implementation and validation of irregular granular shape physics modeling in CFDRC's gas-granular multi-phase flow solver. An approach for extension to poly-disperse particle mixture simulations was also developed. Full integration of these models in Phase II will enable the simulation of gas flow interaction with poly-disperse, irregular shaped particle materials. Extensive verification, validation, and application demonstrations will be performed. The proposed technology development will result in unprecedented computer modeling capability for predicting liberation and flow of realistic granular material compositions in extreme extra-terrestrial environments.

Description

<p>The areal density of solar sails and laser sails is large due to the heavy support structure made of Mylar, Kapton or CP-1. Replacing this support structure with graphene essentially eliminates this mass resulting in a 87% weight savings compared to traditional solar sails, given that graphene is one-atom thick. This weight savings allows for more payload mass, greater acceleration or a combination of the two.  This project will investigate if graphene can be used as the solar sail support structure and if significant improvements in areal density can be achieved.  The objective of the project is to show feasibility of fabricating light sails by coating a thin layer of metal on a graphene support structure to obtain low area density sails.  Graphene is a single atom thick layer of carbon which is invisible to the naked eye. It often comes on a metal substrate such as nickel or copper.  The graphene will be characterized by using Raman Spectroscopy to determine the quality and coverage of the surface.  Our approach will use the substrate as a support structure by covering the metal on the edges so the middle section is etched away when it is suspended in the etchant, leaving a free graphene layer suspended in air.  This graphene will then be coated with a thin layer of metal by sputter coating a 100 or 50 nm thick layer.  Another approach will be to first sputter coat the metal and them etch away the nickel or copper substrate.  The edges of the substrate will be covered by tape and the middle section will be etched away.   Future work will consist of developing low areal density sails with high-reflectivity and high-temperature optimized to enable the highest possible acceleration both for solar and laser sails.</p><p>Both methods were attempted and the second method enabled us to fabricate the sail.  Some of the challenges found in the process was the surface tension in the etchant which tended to pull on the graphene causing it to break away from the substrate and float on the surface.  Graphene typically has many cracks and imperfections which we believe enabled the material to separate away coupled with the chemical process.  After modifying the approach, we were able to make some sail samples which we tested using Raman Spectroscopy.  The metal sail layer does shield out the Raman Spectroscopy signature of the graphene so verification of the graphene was not completely possible since the signature was shielded out, but some evidence was apparent.  An attempt was made to use AFM to verify that the graphene layer exists and supports the metal layer, but technical issues with the Atomic force microscopy (AFM) prevented us from obtaining results.  Ultraviolet-visible spectroscopy (UV-Vis) was used to quantify the optical transmissivity at various wavelengths, which was very low at about 2%.  The optical reflectometer  was not operational due to a recent failure in the system, so no true values on reflectivity were obtained.  Once this equipment is operational, testing will be conducted on the reflectance of the material.  The work is significant because it lays the groundwork for interstellar precursor missions for human exploration.</p>

Description

As NASA prepares for future exploration activities on the Moon, there is a growing need to develop higher fidelity lunar soil simulants that can accurately reproduce the properties and behavior of lunar soil. Simulants are employed on earth to verify the performance of equipment, mechanisms, structures and processes to be used on the lunar surface. One of the significant limitations of current simulants is the lack of constituents, such as agglutinates and spherules, which often contain nano-phase iron (Fe0). These constituents are needed in any high fidelity simulant. Recently, Plasma Processes, Inc. (PPI) has developed a process to create simulated agglutinates and volcanic glasses from JSC-1A lunar regolith simulant. Microstructural characterization has shown that these components contain an appreciable amount of nano phase Fe0. However, current production of these simulant additives is limited. The ultimate objective of this Phase I effort is to develop an economical, large scale manufacturing process to produce simulant agglutinates and volcanic glasses. This production process promises to be a viable route for significantly enhancing the fidelity of existing and future lunar regolith simulants.

Description

This GeoTiff is a mosaic of World View 2 panchromatic satellite imagery of Northeast Puerto Rico that contains the shallow water area (0-35m deep) surrounding Northeast Puerto Rico and Culebra Island. The WV2 imagery was processed using ArcGIS tools to cloudmask, deglint and water-column correct the image (Lyzenga method) then using PCI imagery analysis to create a continues, color balanced mosaic. The DigitalGlobe WV2 is a commercial high resolution (0.5m - 1.5m) multi-spectral satellite that surveyed the NEPR area in 2011-2013. The enhanced Red, Green, Blue and Near Infrared 1 bands allowed the Biogeography branch to delineate habitats using feature extraction tools in Envi 5.1 software. The multispectral bands were analyzed to detect coral reefs and seagrass beds under the surface of the water, as well as features above the surface, such as mangroves, salt ponds, and the shoreline edges. The WV2 mosaic, the bathymetry model, principle component analysis, and aerial imagery were all used integrally to create the NEPR Benthic Habitat Map.

Description

This part of SIM 3254 presents data for the geologic and geomorphic map (see sheet 10, SIM 3254) of the Offshore of Ventura map area, California. The vector data file is included in "Geology_OffshoreVentura.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreVentura/data_catalog_OffshoreVentura.html. The offshore part of the map area largely consists of a relatively shallow (less than 40 m deep), gently offshore-dipping (less than 1 degree) shelf underlain by recent marine and deltaic deposits of the Santa Clara and Ventura Rivers. The mean annual sediment load of these two rivers exceeds 3.25 kt/yr (Warrick and Farnsworth, 2009a), and the area is largely part of an extensive Quaternary deltaic depocenter (Dahlen, 1992; Slater and others, 2002; Sommerfield and others, 2009). Shelf deposits are primarily sand (Qms) at depths less than about 25 m and, at depths greater than about 25 m, are more fine-grained sediment (very fine sand, silt and clay) (Qmsf). The boundary between Qms and Qmsf is based on observations and extrapolation from sediment sampling (for example, Reid and others, 2006) and camera ground-truth surveying (see sheet 6, SIM 3254). Given that this is an area of abundant sediment supply and active sediment transport (Barnard and others, 2009; Warrick and Farnsworth, 2009a), it is important to note that the boundary between Qms and Qmsf should be considered transitional and approximate and is expected to shift as a result of seasonal- to annual- to decadal-scale cycles in wave climate, sediment supply, and sediment transport. Offshore of the mouth of the Ventura River, at water depths of between 20 and 30 m, the sandy shelf (Qms) includes an area of irregular arcuate depressions floored by coarser sediment (coarse sand and possibly gravel; Qmss). Such features have been referred to as "rippled-scour depressions" (for example, Cacchione and others, 1984) or "sorted bedforms" (for example, Goff and others, 2005; Trembanis and Hume, 2011). Although the general area in which Qmss depressions are found is not likely to change substantially, the boundaries of the unit(s), as well as the locations of individual depressions and their intervening flat sand sheets, likely are ephemeral, changing during significant storm events. Coarser grained deposits (Qmsc), which are recognized on the basis of high backscatter (sheet 3, SIM 3254), camera observations (sheet 6, SIM 3254), and sampling (Reid and others, 2006; Barnard and others, 2009), are found locally in water depths less than about 15 m. These units are concentrated at the mouths of the Santa Clara and Ventura Rivers and a few smaller coastal watersheds to the northwest, and they are inferred to represent wave-winnowed lags of deltaic sediment. It is likely that these deposits are ephemeral and are commonly covered by finer grained sediment. However, a few outcrops of Qmsc between Ventura and Pitas Point are not obviously tied to coastal watersheds. One large area in particular is characterized by high backscatter and rugosity (sheets 3 and 5, SIM 3254, respectively); camera ground-truth aurveying (sheet 6, SIM 3254) reveals that this area consists of boulder, cobble, gravel, and sand. The area lies immediately offshore of steep slopes underlain by variably consolidated Pliocene and Pleistocene deposits (sand, gravel, cobbles) of the Pico, Santa Barbara, and Saugus Formations (onshore units Tp, QTsb, and Qs, respectively), which are highly susceptible to landsliding (Tan and others, 2003a,b); thus, this area mostly likely represents wave-winnowed landslide deposits. It is also possible that these high-backscatter areas are partly underlain by bedrock, as is inferred on sheet 7 (SIM 3254). The steep onshore slopes are immediately north of, and in the hanging wall of, the active Pitas Point Fault, a location that undoubtedly has contributed to slope instability. The seafloor bedrock exposures south and west of Punta Gorda are inferred to consist of the Pico Formation (Tp) on the basis of their backscatter, rugosity, and relief, as well as adjacent exposures of Tp in coastal bluffs and platforms and their similar location along the axis of the Rincon-Ventura Avenue Anticline (Tan and others, 2003a,b). A few shallow (less than 10 m deep) areas offshore between Punta Gorda and Pitas Point are inferred to be underlain by a composite unit (Qms/Tp) consisting of the Pico Formation overlain by a thin (probably ephemeral) marine-sediment layer. The Offshore of Ventura map area is in the Ventura Basin, in the southern part of the Western Transverse Ranges geologic province, which is north of the California Continental Borderland (Fisher and others, 2009). This province has undergone significant north-south compression since the Miocene, and recent GPS data suggest north-south shortening of about 6 to 10 mm/yr (Larson and Webb, 1992; Donnellan and others, 1993). The active, north-verging Oak Ridge Fault and the south-verging Pitas Point-Ventura Fault are two of the structures on which this shortening occurs (for example, Sorlien and others, 2000; Fisher and others, 2009). High-resolution seismic-reflection data (sheet 8, SIM 3254) reveal that neither fault ruptures the surface; instead the surface expression of each fault is a narrow, asymmetric fold that involves the uppermost Pleistocene and Holocene (less than 21 ka) sedimentary section. Both structures are inferred to be parts of long fault systems that extend for more than 100 km, representing important potential earthquake hazards (for example, Fisher and others, 2009). Shortening is also occurring on the Montalvo Fault and Anticline system along the southeast edge of the map area (part of the broader Oak Ridge Fault Zone; Yeats, 1998) and on the Rincon-Ventura Avenue Anticline (for example, Rockwell and others, 1988), which crosses the northwest edge of the map area.

Description

Los Gatos Research proposes to develop a new automated health monitoring sensor system capable of monitoring distributed load and acoustic emission (AE) for rapid inspection of damages in composite overwrapped pressure vessels (COPV). Our novel sensor technology offers a number of advantages including sensor compactness and lightweight with multiplexing capability for load and AE for monitoring and characterizing damages in advanced composite structures and components. We achieve this by employing Bragg grating sensor arrays and using a novel interrogation technique combined with state-of-the-art AE method to detect and pinpoint composite defects in these structures. In Phase I, we have demonstrated the sensor's capability to measure crack-induced acoustic emissions in a composite overwrapped pressure vessel structure loaded up to rupture pressure. In Phase II, the grating sensors, interrogation system, and diagnostic software will be integrated into an automated system, capable of measuring and correlating the load history, acoustic emission activity, and determining the severity of damages and their location in the COPV. This dedicated prototype will include an integrated fiber optic conditioning hardware, state-of-the-art AE hardware and software, and address the power and stability requirements unique to ground based and in-flight studies.

The National Reporting System for Adult Education, 2009-10 (NRS 2009-10) is part of the Adult Education and Family Literacy program; program data is available since 1997 at . NRS 2009-10 (http://www.nrsweb.org) is a cross-sectional study that was designed to monitor performance accountability for the federally funded, state-administered adult education program. States were required to submit their progress in adult education and literacy activities by reporting data on core indicators of outcomes on all adult learners who receive 12 or more hours of service as well as state expenditures on the adult education program. States could also report on additional, optional secondary measures that included outcomes related to employment, family, and community. The study was conducted using a web-based reporting system of states. NRS 2009-10 is a universe survey, and all states submitted data. Key statistics produced from the study include student demographics, reasons for attending the program, receipt of secondary school diploma or general education development (GED) certificate, placement in postsecondary education or training, educational gain, and employment placement and retention.

Description

The Missisquoi Wilderness Study concluded that nearly the entire wildlife refuge is, or will be, needed for intensive waterfowl habitat management. The Fish and Wildlife Service, however, proposed wilderness designation for the 114acre Shad Island in the northern end of the refuge. This proposal for wilderness designation of the 620acre area within the Missisquoi National Wildlife Refuge involved consideration of the following factors: 1 the preservation of 620 contiguous acres including the 114acre Shad Island in a natural state. 2 The effect on existing and future public uses of the area. 3 The impact of the proposal on existing and future economic, cultural, and social values. 4 The effect on refuge programs and the attainment of refuge objectives.

Description

This Bonneville Power Administration (BPA) - funded project pays for NOAA staff to operate the adult salmon trap located in the fish ladder at Lower Granite Dam. The trap is operated to provide access to fish for sampling for several NOAA projects as well as other researchers from many agencies. The trap is used for random sampling of adults used in run reconstructions, determining age classes of returning adults, assess injuries from marine mammals, brood stock collection for hatcheries, scale sampling to determine age of ocean entry for fall Chinook, radio tagging of adults, and various other uses. NOAA has operated this trap since it was built in the mid-1970s, with BPA funding beginning in 2006. An annual report is provided to BPA summarizing trap activities. Lower Granite Dam adult trap data
