Description

<p>The full potential of small spacecraft remains untapped because they lack maneuverability. Plasmonic force propulsion provides attitude control capability for small spacecraft with no power penalty and minimal mass and volume penalty. This creates new capabilities for small spacecraft enabling NASA science and exploration missions that were previously impossible. One of NASA’s strategic goals is expanding scientific understanding of the Earth and the universe. NASA envisions a broad class of scientific missions where extremely fine pointing and positioning of spacecraft is required, such as a single Earth observing spacecraft, deployable x-ray telescopes, exoplanet observatories, and constellations of spacecraft for Earth and deep space observations. In recognizing this, the National Research Council emphasized the need for micro-propulsion for extremely fine pointing and positioning of micro-satellites for astrophysics missions.</p><p>Within the context of these types of missions, we propose to assess the ability of plasmonic force propulsion to advance the state-of-the-art. We propose to numerically simulate plasmonic force fields with asymmetric/gradient geometry and relevant solar light constraints, predict nanoparticle velocity, mass flow rate, and resulting propulsion performance (thrust, specific impulse), and evaluate spacecraft position control resolution and pointing precision enabled by plasmonic propulsion. We will compare our results with state-of-the-art thrusters (e.g., colloid/electrospray electric propulsion) and torquers (e.g., reaction wheels). We will also assess the feasibility of plasmonic propulsion to meet and/or exceed the stringent demands of future NASA missions.</p>

Description

<p> An ultra-compact superconducting on-chip-spectrometer has the potential to revolutionize far-IR through millimeter-wave observational astronomy and astrophysics, allowing for the first time wide-field mm- and sub-mm spectral surveys and efficient follow up observations of known sources. Our ultimate plan is to use planar lithography to fabricate superconductin g transmission line filters to sort incident radiation by frequency to an array of direct detectors such as MKIDs. However, for this task, we are only focusing on the antenna array element and coupling structures which will couple energy from the telescope to the spectrometer chip. We will design and fabricate a 2x2 array of multi-flare-angle smooth walled horn array to demonstrate the feasibility of this concept for the spectrometer-on-a-chip as well as other focal plane arrays in the submillimeter-wave frequency band. The 2x2 horn array antennas will be fabricated using a tool which can make hundreds of arrays of horn antennas without much difficulty. This is the key innovation of this approach. The horn array will be designed for the 190-320 GHz frequency band. We will also design and fabricate a 2x2 array of circular to rectangular transition block which will be used to test the performance of the horn array. Fig. 1 shows the design concept and that fabrication tool that will enable fabrication of antenna arrays with hundreds of pixels.</p>

Description

The marine mammal and sea turtle layers in MarineCadastre.gov represent habitat-based density-model estimates of animal density. The marine mammal layers are a subset of a larger data set being delivered via the Cetacean and Sound Mapping website (http://cetsound.noaa.gov) of the National Oceanic and Atmospheric Administration (NOAA). The model results show estimates of the average number of animals present per square kilometer during a given season. Most of the average estimates of animals per km2 are less than 1 because marine mammals are highly mobile and often occur in large groups. For example, an average value of 0.5 bottlenose dolphins per km2 during the summer could mean that 1 animal would be present every other day, or 1 group of 5 animals would be present once in a 10 day period, or 1 group of 50 animals would be present every 100 days, etc. These data originate largely from marine mammal observations generated through shipboard and aerial surveys conducted by NOAA's National Marine Fisheries Service. Models explicitly incorporate environmental factors whenever possible. The model outputs were generated through a collaborative effort that included NOAA, the U.S. Navy, and Duke University.

Description

_(Abstract):_ Each TMY is a data set of hourly values of solar radiation and meteorological elements for a 1-year period. Solar radiation is modeled using the NREL METSTAT model, with surface observed cloud cover being the principal model input. The container file contains one TMY file for each selected station in the region, plus documentation files and a TMY data reader file for use with Microsoft Excel. _(Purpose):_ Simulations _(Supplemental Information):_ A TMY consists of months selected from individual years and concatenated to form a complete year. The intended use is for computer simulations of solar energy conversion systems and building systems. Because of the selection criteria, these TMYs are not appropriate for simulations of wind energy conversion systems. A TMY provides a standard for hourly data for solar radiation and other meteorological elements that permit performance comparisons of system types and configurations for one or more locations. A TMY is not necessarily a good indicator of conditions over the next year, or even the next 5 years. Rather, it represents conditions judged to be typical over a long period of time, such as 30 years. Because they represent typical rather than extreme conditions, they are not suited for designing systems and their components to meet the worst-case conditions occurring at a location.

Description

Metal, hydrocarbon, or nutrient data have not been recorded for the Arctic coastal plain 1002 area of the Arctic National Wildlife Refuge Arctic Refuge in areas of prospective oil and corridor development. Predevelopment baseline data for contaminants are necessary to enable general characterization of water quality and contaminant residues, as well as to provide sitespecific predevelopment information in the event of a Congressional decision to open the Arctic coastal plain to oil and gas exploration and development. This study examines 19881989 samples of sediments, water, sedge, birds, invertebrates, and fishes from the 1002 area. Volume 1 of the three volumes in this report describes the study area, study sites, methods, and objectives, and provides summary statistics geometric mean, arithmetic mean, arithmetic standard deviation, maximum, minimum, and median for those analytes with more than 23 of the concentrations greater than the limit of detection. Volume 2 contains the raw metal and hydrocarbon contaminant data, and the raw water quality data. Volume 3 summarizes quality assurancequality control QAQC results which include mean relative percent differences RPDs from duplicate analyses, mean percent recoveries from spiked analyses, mean recoveries and Z scores from standard reference material analyses, and maximum concentrations from blank analyses. For a comprehensive description of all quality assurancequality control methods, also see Volume 1. These reports provide a database on a sufficient number of aquatic, terrestrial, and lagoon samples to enable general characterization of water quality and contaminant residues, as well as to provide site specific predevelopment information. The reader is strongly encouraged to use the QAQC data in Volume 3 to assess data quality on an analytebyanalyte basis for each sample matrix. This information will be used by Refuge management and State and Federal regulators to assess any post development changes that result from any oil and gas exploratory or production activities. The data will also be useful in evaluating special use permits, Clean Water Act Sections 402 and 404 permits, and State wastewater permits, and in recommending appropriate mitigation measures if development occurs on the 1002 area.

Description

Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters and causes; and (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset (NHD). Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale data (frequently provided by state GIS layers).

Description

NASA's Future Air traffic management Concepts Evaluation Tool (FACET) is a simulation tool to evaluate next generation air traffic management (ATM) systems. FACET has been gaining popularity with ATM researchers in research years due to its well-designed user interface and robust capabilities for simulating the interaction between the National Airspace System (NAS) and new ATM concepts. Since controller task load and performance is a critical aspect of any future ATM concept, we propose to integrate human performance metrics into FACET. Currently, the only representation of human performance in FACET is through calculation of dynamic density, which estimates controller task load at the sector level through regression analysis of subjective controller ratings for current operations. However, the applicability of dynamic density in its current form for predicting controller task load of future ATM operations is unknown. By integrating human performance metrics directly into FACET, preliminary task load implications and predictions of workload-constrained sector capacity of any future ATM concept would be immediately available to researchers. This would be particularly useful to future ATM tradeoff studies and could be used in lieu of subjective controller ratings for preliminary recalibration of dynamic density for future ATM operations.

This part of DS 781 presents data for the bathymetry and shaded-relief maps of Offshore of San Francisco, California (raster data file is included in "Bathymetry_OffshoreSanFrancisco.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreSanFrancisco/data_catalog_OffshoreSanFrancisco.html. The bathymetry and shaded-relief maps of Offshore of San Francisco, California, were generated from bathymetry data collected by Fugro Pelagos, and by California State University, Monterey Bay (CSUMB). Mapping was completed between 2004 and 2008, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders. These mapping missions combined to collect bathymetry (sheets 1, 2) from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters. A large portion of this map area was re-mapped in 2009, however the older bathymetry data were used in this map due to co-registered, acoustic backscatter data. NOTE: the horizontal datum of the bathymtry data (NAD83) differs from the horizontal datum of other layers in this SIM (WGS84). Some bathymetry grids within this map were projected horizontally from WGS84 to NAD83 using ESRI tools to be more consistent with the vertical reference of the North American Vertical Datum of 1988 (NAVD88). These data are not intended for navigational purposes.

Description

The Topological Faces / Area Hydrography Relationship Files (FACESAH.dbf) contain a record for each face / area hydrography feature relationship. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The face to which a record in the Topological Faces / Area Hydrography Relationship File (FACESAH.dbf) applies can be determined by linking to the Topological Faces Shapefile (FACES.shp) using the permanent topological face identifier (TFID) attribute. The area hydrography feature to which a record in the Topological Faces / Area Hydrography Relationship File (FACESAH.dbf) applies can be determined by linking to the Area Hydrography Shapefile (AREAWATER.shp) using the area hydrography identifier (HYDROID) attribute. A face may be part of multiple area water features. An area water feature may consist of multiple faces. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.
