Description

Bathythermograph data were collected from the TANEY within a 1-mile radius of Ocean Weather Station H (3800N 07100W) and in transit. Data were collected by the United States Coast Guard from 01 August 1973 to 23 August 1973. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instrument. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

Description

Survey of the southeastern Hawaiian Ridge was the fifth major segment of the Exclusive Economic Zone (EEZ) mapping program to have been initiated. Data acquisition for this region required approximately one-half year and were acquired during eight cruises over a four year period from 1986 through 1989, skipping 1987. At the conclusion of the survey 29 mosaics of a 2 degree by 2 degree were completed for the region. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of twenty-seven digital mosaics of a 2 degree by 2 degree area and 2 mosaics of 2.25 degree by 2 degree with a 50-meter pixel resolution were completed for the region.

Description

This image represents a 4 meter resolution backscatter mosaic of of a sharply sloping swath of the St. John Shelf, south of St. John, US Virgin Islands. NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the US Virgin Islands from 3/28/2011 to 4/14/2011. Data was acquired with a hull-mounted Kongsberg 1002 multibeam echosounder (95 kHz) and 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 from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using Hypack 2011 Geocoder software. Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing surficial seafloor features and delineating benthic habitats.The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

Description

This SBIR seeks to improve the definition of design loads for rocket engine components such that higher performing, lighter weight engines can be developed more quickly. The long-term goal of this SBIR program is to substantially improve the overall load determination by demonstrating and validating new methods. The overall plan includes advances in computational fluid mechanics to provide more accurate tools for estimating the nozzle side loads and fluctuating pressure loads as well as the interaction between system models and components models and the combination of dynamic loads for prediction of component margins and life. The Phase I detailed development includes a tightly-integrated coupling of computational fluid dynamics and structural dynamics codes to better predict the nozzle side loads due to flow separation. In addition, improvements will be identified to both the loads process and the combination of dynamic loads in the time domain to support finite fatigue life predictions. These improvements to the loads definition will provide an improvement to the engine development process by providing better loads estimations which can be used to reduce conservatism and to significantly improve performance with reduced weight, cost, and development time. Phase II will include efforts to validate the fluid-structure interaction tool with experimental data and further develop and validate the new loads process methodologies.

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 Universal Transverse Mercator Coordinate System (ZONE 17N) and Lambert Conformal conic projection.F The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

Description

On August 17, 1996, the Japanese Space Agency (NASDA - National Space Development Agency) launched the Advanced Earth Observing Satellite (ADEOS). ADEOS was in a descending, Sun synchronous orbit with a nominal equatorial crossing time of 10:30 a.m. Amoung the instruments carried aboard the ADEOS spacecraft was the Ocean Color and Temperature Scanner (OCTS). OCTS is an optical radiometer with 12 bands covering the visible, near infrared and thermal infrared regions. (Eight of the bands are in the VIS/NIR. These are the only bands calibrated and processed by the OBPG) OCTS has a swath width of approximately 1400 km, and a nominal nadir resolution of 700 m. The instrument operated at three tilt states (20 degrees aft, nadir and 20 degrees fore), similar to SeaWiFS.

Description

We propose to develop a compact portable longwave camera for astronomical applications. In Phase 1, we successfully developed the eye of the camera, i.e. the focal plane array (FPA) and produced good imagery with it. In Phase 2, we will optimize the FPA for quantum efficiency and pixel operability, integrate it into a dewar cooler assembly, and package the resulting sensor engine with electronics and optics into a camera system. We will deliver the camera to NASA for field testing. We expect the camera to be particularly useful in the search for cold objects in the universe and in the measurement of atmospheric gases with absorption lines in the spectral response band of the camera.

Description

Recent R&D associated with designing high speed rotorcraft has been greatly hampered by a lack of test data and confidence in predictions for rotors operating above advance ratio 1.0. This proposal outlines a plan for addressing this situation through a series of rotor tests and analytical enhancements. The three-pillared approach begins with a model rotor test in Phase I that will obtain essential data on autorotation characteristics of rotors operating at high advance ratio. The second pillar will involve analytical enhancements for comprehensive rotorcraft analyses featuring an improved yawed flow correction and an improved lifting surface blade model that will properly shed wake off the "leading edge" of blades operating as reverse velocity rotors. The third pillar will focus on improving grid generation methods for CFD solutions to appropriately model reverse and spanwise flow regions. Phase II will see additional rotor tests and model improvements followed by incorporation of new technology into a software module suitable for immediate implementation in rotorcraft analysis and flight simulation software. The new software module will provide a hierarchy of methods capable of modeling high speed rotorcraft blade aerodynamics for a broad spectrum of fidelity/speed requirements ranging from real-time flight simulation to high resolution CFD.
