Summary
Description
This project is a cooperative effort between the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment, the University of Hawaii, and Analytical Laboratories of Hawaii, LLC. The goal of the work was to develop coral reef mapping methods and compare benthic habitat maps generated by photointerpreting georeferenced color aerial photography, hyperspectral and IKONOS satellite imagery. The enhanced spectral resolution of hyperspectral and control of bandwidths of multispectral data yield an advantage over color aerial photography particularly when coral health and time series analysis of coral reef community structure are of interest. Depending on the type of instrument, a spectral imaging system can be utilized to see multiple colors from ultraviolet through the far infrared range. The AURORA hyperspectral imaging system collected 72 ten nm bands in the visible and near infrared spectral range with a 3 meter pixel resolution. The data was processed to select band widths, which optimized feature detection in shallow and deep water. Photointerpreters can accurately and reliably delineate boundaries of features in the imagery as they appear on the computer monitor using a software interface such as the Habitat Digitizer.

2003 U.S. Geological Survey (USGS) Experimental Advanced Airborne Research Lidar (EAARL): US Virgin Islands (St. John, St. Croix)
Published By National Oceanic and Atmospheric Administration, Department of Commerce
Issued over 9 years ago
Summary
Description
This data set contains topographic and bathymetric lidar data that were collected on April 21, 23, 30, May 2, and June 14, 17 of 2003, cooperatively by the U.S. Geological Survey (USGS), National Aeronautics and Space Administration (NASA), and National Park Service (NPS). The data is for part of the U.S. Virgin Islands (island of St. John and a portion of the northern coastline of St. Croix). The bathymetric lidar data are classified as 11 and the topographic lidar data are classified as 0. A first surface and submerged topography elevation map (also known as a Digital Elevation Model, or DEM) of a portion of the U.S. Virgin Islands (island of St. John and a portion of the northern coastline of St. Croix) was produced from remotely sensed, geographically referenced elevation measurements cooperatively by the U.S. Geological Survey (USGS), National Aeronautics and Space Administration (NASA), and National Park Service (NPS). Elevation measurements were collected over the area using the NASA Experimental Advanced Airborne Research Lidar (EAARL), a pulsed-laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high frequency laser beams directed at the Earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The plane travels over the target area at approximately 50 meters per second at an elevation of approximately 300 meters. The EAARL, developed by NASA at Wallops Flight Facility in Virginia, measures ground elevation with a vertical resolution of 15 centimeters. A sampling rate of 3 kilohertz or higher results in an extremely dense spatial elevation dataset. Over 100 kilometers of coastline can be surveyed easily within a 3- to 4-hour mission. When subsequent elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.

This data set contains three data files in text format (.txt) for a temperate dry steppe at Rio Mayo, Argentia. One file contains quarterly above-ground biomass data for grasses on the steepe (May 1984-May 1985). The second file contains average annual above-ground primary production (ANPP) data for grasses and shrubs for years 1972-1997 based upon peak above-ground biomass estimates. The third file contains precipitation and maximum/minimum temperature data for the Rio Mayo site for the period 1968 through 1990.Rio Mayo is located in the Patagonia region of Argentina. The vegetation is chiefly composed of grasses and shrubs. Harvest methods were used to estimate grass and shrub production. Between 1972 and 1997, peak annual ANPP of grasses plus shrubs ranged from 21 to 75 g/m2/yr, with an average of about 60 g/m2/yr. Grasses accounted for about two-thirds of the productivity. ANPP was reduced in a drought year, but did not increase in relatively wet years, suggesting that it may not be linearly related to precipitation. ANPP for 1984-1985 was slightly higher (79 g/m2/yr) when a different algorithm was used for estimation. Revision Notes: The original npp data file (rmy_npp.txt) has been split into two files, one file containing seasonal biomass and the other containing annual ANPP estimates. The data file containing annual ANPP estimates has been revised to extend temporage coverage and add additional annual ANPP data. See the Revisions section in this document for details.

Description
An all-composite driveshaft incorporating integral flexible diaphragms is described and proposed for further refinement. An approach is explored which obsoletes the split lines and associated fasteners required to attach metallic flex elements and either metallic or composite spacing tubes in current solutions. Sub-critical driveshaft weights half that of incumbent technology are projected for typical rotary wing shaft lengths. Spacing tubes are described, which comprise an integral part of the initial tooling but which remain part of the finished shaft and control natural frequencies and torsional stability. A concurrently engineered manufacturing process and design for performance is proposed which competes with incumbent solutions at significantly lower weight and with the probability of improved damage tolerance and fatigue life. This phase I proposal seeks to further remove manufacturing cost and to produce test articles suitable for concept verification and, subsequently, flight qualification during phase II.

Description
Indiana Integrated Circuits, LLC (IIC) proposes to develop the customizable, high-performance microchip interconnect technology called Quilt Packaging (QP) to address NASA's requirement for high performance integration of heterogeneous microwave systems. QP is an affordable, scalable, patented edge-interconnect technology for joining microchips of disparate materials and/or process technologies into monolithic-like systems that perform electrically as if they were one chip. QP enables sub-micron chip-to-chip alignment, extremely small (< 10 micron) chip-to-chip gaps, and can be implemented in multiple substrate materials, including SiGe, GaAs, Si, InP, GaSb, SiC, GaN, and more. Quilt Packaging can enable extremely low-loss, wide-bandwidth integration of MMIC modules comprising disparate material systems and/or process technologies. QP has demonstrated less than 0.1 dB insertion loss up to 100 GHz, and under 1 dB out to 220 GHz. Initial reliability testing of QP chipsets have demonstrated no degradation or mechanical issues, having undergone thermal cycling from -40 C to 125 C for over 350 cycles and counting. In addition to excellent microwave performance, QP has the potential for decreasing system size, weight and power. The proposed effort will leverage previous work in GaAs and Si QP to demonstrate a heterogeneously integrated "quilted" chipset of SiGe, GaAs and/or InP chips. Resulting data from this Phase I will directly apply to the design, fabrication and demonstration of a functioning MMIC module in Phase II. Throughout Phase I consideration will be given to NASA system needs and transition to production-level Quilt Package chip fabrication with commercialization partners Research Triangle Institute and Northrop Grumman Corp. for manufacturing scale-up of Quilt Packaging enabled MMIC modules.

NOAA ESRI Geotiff - 6m Multibeam Bathymetry, Puerto Rico (Isla de Mona) - Project NF-08-04, , UTM 19N NAD83
Published By National Oceanic and Atmospheric Administration, Department of Commerce
Issued over 9 years ago
Summary
Description
This dataset contains an ESRI Geotiff with 6 meter cell size representing the bathymetry of selected portions of seafloor around Isla de Mona in Puerto Rico, derived from data collected in 2008. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in Puerto Rico from 2/25/08 to 3/8/08. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) in 2008. It was processed by a NOAA contractor using CARIS HIPS software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 19 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and imported to ESRI ArcMap 9.2 using the 'Convert XYZ to Raster' tool developed by CCMA for this purpose. This was used to produce the final Geotiff. The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependent on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
