Description

Sablefish (Anoplopoma fimbria) have a wide distribution along the Pacific coast, extending from Baja California to Alaska, the Bering Sea and through to the eastern coast of Japan. A unique feature of these fish is the wide variation in temperature and depth that sablefish experience throughout their life cycle, extending from depths 200m as adults to the surface as larvae and juveniles. While the landed weight of sablefish in the commercial fishery is relative small, the exceptionally high value of this species ranks it 3rd in economic value to walleye pollock and Pacific cod. As such, sablefish are highly managed throughout the Pacific, and understanding the biology of this species is essential for proper management. The aim of this project is to characterize the reproductive life history of two populations of sablefish in coastal Washington and California. Fish will be collected from the same geographical location on a monthly basis for one year. The reproductive status will be determined from gonadal histology and plasma sex steroid levels, and age will be determined from otoliths. It is expected that data on size, age, rate of gonadal development, seasonal timing of spawning, fecundity, frequency of reproduction, and potential shifts in distribution of sexes will be obtained. This study applies directly to the Magnuson-Stevens Fishery Conservation and Management Reauthorization Act, because the data will be used to improve stock assessments and estimates of spawning biomass in this commercially important species. This project is a cooperation with the commercial fishing industry and scientists at the Northwest Fisheries Science Center (NWFSC) and Southwest Fisheries Science Center (SWFSC). Size, sex, gonad stage, fecundity

Description

The Center for Coastal Monitoring and Assessment (CCMA) conducted the third year of an ongoing scientific research mission on board the NOAA ship NANCY FOSTER. The purpose of this cruise is to support the benthic characterization of coral reef habitat in the U.S. Virgin Islands and Puerto Rico. The mission explored, surveyed, and mapped moderate depth bathymetry (30 – 1000 meters) with the NANCY FOSTER’s Simrad EM1002 multibeam system for natural resource management and seafloor characterization. Multibeam bathymetry and backscatter was collected along with Remotely Operated Vehicle (ROV) underwater video. Priority areas for 2006 included the deep water portion of the Buck Island Reef National Monument north of St. Croix and the La Parguera region along the southwestern coast of Puerto Rico. Additional multibeam data was collected to merge with pre-existing shallow water bathymetry from previous CCMA cruises in the Buck Island vicinity.

Description

DyMA-FM (Dynamic Multivariate Assessment for Fault Management) is a software architecture for real-time fault management. Designed to run in a distributed environment, DyMA-FM enables model-based reasoning and predictive modeling for FM applications. With the appropriate hardware, DyMA-FM can respond to signals at the device level while still placing each signals in context with the larger system and the overall mission objective. This functionality is enabled by a layered software architecture and decision-making hierarchy where each level receives signals from the level below and context from the level above. The contextual processing reduces false alarms and increases fault coverage. The distributed architecture, meanwhile, speeds processing time and reduces the burden on the communication system, enabling faster and more robust response to fault conditions. Building on our current and past experience with distributed system management and mathematical modeling, we will implement and test a prototype of the proposed software. Test data will be provided by Boeing Corporation and will consist of a representative set of signals from an actual spacecraft, collected either under actual use conditions or during a system test. Implementation will require the development of mathematical models that represent the relationships between the test signals, and this portion of the Phase I tasks will result in an analysis of the model's ability to support fault detection and management. Testing will focus on the software's fault coverage, the speed of the system responses, and the system's sensitivity to timing issues such as message lag and message collision. Results from initial tests will be reviewed, and suggested changes to the software will be documented. The final output from the project will include the system prototype, test results, and an analysis of the DyMA-FM's ability to produce superior fault coverage.

The data sets are generated using the OPTECH ALTM 70 kHz LIDAR system mounted onboard AeroMap's twin-engine Cessna 320 aircraft. Classified data sets such as this one may have varying posting due to some LIDAR pulses not reaching the ground caused by data anomalies. Accuracy statements are based on areas of moderate terrain. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected to meet the vertical accuracy standard; however, derived products may be less accurate in extreme terrain and dense vegetation due to a lesser number of points defining the bare-earth in these areas. The data were QA/QC'ed but some data holidays still exist. This data represents the last return data only.

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 UTM 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.

Description

Despite the rapid commercialization of additive manufacturing technology such as selective laser melting, SLM, there are gaps in process modeling and material property prediction that contribute to slow and costly process qualification and product certification. To address these gaps, CFDRC and our partner Dr. Kevin Chou, University of Alabama, will develop multiple computationally efficient, high-fidelity simulation tools for the SLM process. During Phase I the team will apply adaptive meshing to enable efficient thermomechanical simulations for centimeter size test coupon builds, leverage existing multiphase flow models to analyze particle size effects on material variations, apply phase field models to predict microstructure evolution, and evaluate model predictions against experimental characterization. During Phase II, the modeling tools will be extended to improve computational efficiency and scalability to aerospace component dimensions by further leveraging parallel computing and other acceleration techniques. The fidelity of the models will be enhanced to better predict distortion, residual stress, microstructure and defects from process conditions; and additional process data will be used to validate the resulting codes. The resulting toolset will be capable of efficiently predicting these dimensional and microstructural properties of SLM components from process conditions, while addressing important design and build features such as overhanging sections and build supports. The high-fidelity, physics based nature of the codes will allow straightforward application to new materials, and to guiding development of and verifying analytical physics models for process control.

Description

The San Bernardino National Wildlife Refuge was established in 1982 for the protection and management of endangered desert fishes which are indigenous to the Rio Yaqui drainage. The 2,309acre refuge is located on the United StatesMexico border 16 miles east of Douglas, Arizona. Collectively, copper smelter emissions in southern Arizona and northern Sonora have a created a regional atmospheric condition where mean annual precipitation pH is 4.7 to 5.0. Background chemistries are largely unavailable and influence of both nonferrous smelter emissions and current agricultural practices and pesticide use remain unexplored. During May and June 1987 water chemistry was determined onsite at each of 13 locations within the refuge including Leslie Creek and sediment and selected tissue samples were collected for trace metals and pesticide analysis. Overall, refuge waters were virtually absent of dissolved trace metals and spring chemistries were relatively consistent due to their presumable origin from a common aquifer. Alkalinity exceeded the EPA recommended minimum of 20 mg1 for freshwater aquatic life by a factor of 10 to 18 and appears to be the mitigating factor which allows acidic deposition to adversely manifest itself in the aquatic ecosystem. Biota are probably the best integrative indicator of water shed quality, and its ability to neutralize acid. Trace metal residues in tissue matrices were mixed in their occurrence, especially for frogs. However, no evidence of acidstress in resident organisms on the refuge was observed. Native fish populations exhibited no symptoms of lack of recruitment, incidence of morphological abnormalities, or subnormal growth. Likewise, bullfrogs flourish throughout the refuge and exhibited little in regard to trace metal body burdens. Periodic biological and chemical monitoring is the recommended course of action to evaluate refuge condition and trend relative to environmental quality.

Description

Jason-3 is the fourth mission in U.S.-European series of satellite missions that measure the height of the ocean surface. Scheduled to launch in 2015, the mission will extend the time series of ocean surface topography measurements begun by the TOPEX/Poseidon satellite mission in 1992 and continuing through the currently operating Jason-1 (launched in 2001) and OSTM/Jason-2 (launched in 2008) missions. These measurements provide scientists with critical information about circulation patterns in the ocean and about both global and regional changes in sea level and the climate implications of a warming world. TOPEX/Poseidon and Jason-1 were cooperative missions between NASA and the French space agency, CNES. Additional partners in the Jason-2 mission included NOAA and Eumetsat. Jason-3 continues the international cooperation, with NOAA and Eumetsat leading the efforts, along with partners NASA and CNES. The primary instrument on Jason-3 is a radar altimeter. The altimeter measures sea-level variations over the global ocean with very high accuracy (as 1.3 inches or 3.3 centimeters, with a goal of achieving 1 inch or 2.5 centimeters). These auxiliary data files are used to generate Level-2 products. They include both static tabular data files and dynamic files which change/grow over time. Auxiliary files are produced outside of OSTM, but are used in product development. Filetypes in the Auxiliary data family (J3-AUX) which are produced by the European Center for Medium range Weather Forecasting (ECMWF) are restricted by ECMWF to the Jason-3 project team. Additional documentation for Jason-3 data is archived at the NODC at: https://archive.nodc.noaa.gov/cgi-bin/AMS/prod/accession/details/118276. The documentation includes metadata in International Standards Organization (ISO) format.

Description

The goal of this SBIR is to adapt an initial prototype ultra-miniature high-performance brushless-DC-motor controller, code named 'Puck', for use by NASA across a wide range of motor drives. The Puck was recently developed by Barrett for terrestrial mobile-manipulation uses where efficiency, low mass, and robustness are critical factors. While quite small (<50 grams), the controller can pump from milliamps to several amps continuous. Several features of this controller make it a candidate for NASA's wide range of needs for servomotor control in the demanding environments of extra-terrestrial and interplanetary exploration. One of the key enabling design strategies that led to the Puck is elimination of transmission lines through total integration of power conditioning, rotor-position optics, and commutation into a single tiny module. The module is small and energy efficient enough to make casting within high-heat-conduction plastic feasible. Pure conduction cooling, a distinct advantage for NASA applications, is unusual for motor amplifiers which are generally cooled by natural convection or forced air. The hermetically-sealed packaging also excludes lunar or Martian dust from affecting robustness. The primary strategy for this technology to avail for NASA will be to minimize the effects of radiation while enabling self-diagnosis, self-repair, and ultimately easy change-out.

Description

These data are qualitatively derived interpretive polygon shapefiles and selected source raster data defining surficial geology, sediment type and distribution, and physiographic zones of the sea floor from Nahant to Northern Cape Cod Bay. Much of the geophysical data used to create the interpretive layers were collected under a cooperative agreement among the Massachusetts Office of Coastal Zone Management (CZM), the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Army Corps of Engineers (USACE). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes because of natural or human effects. The project is focused on the inshore waters of coastal Massachusetts. Data collected during the mapping cooperative involving the USGS have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). The interpretations released in this study are for an area extending from the southern tip of Nahant to Northern Cape Cod Bay, Massachusetts. A combination of geophysical and sample data including high resolution bathymetry and lidar, acoustic-backscatter intensity, seismic-reflection profiles, bottom photographs, and sediment samples are used to create the data interpretations. Most of the nearshore geophysical and sample data (including the bottom photographs) were collected during several cruises between 2000 and 2008. More information about the cruises and the data collected can be found at the Geologic Mapping of the Seafloor Offshore of Massachusetts Web page: http://woodshole.er.usgs.gov/project-pages/coastal_mass/.

Description

The LAT team monitors flux values for a number of bright sources and transient sources that have shown flares during the mission. (See up-to-date weekly reports on flaring sources at the Fermi-LAT Flare Advocate Blog.) As sources cross the monitoring flux threshold of 1x10-6 cm-2s-1, they are added to the monitored source list. (The initial flux threshold was 2x10-6 cm-2s-1, but this value was lowered in June 2009.) In addition to the light curves below, the flux values in several bands are available via Browse. This list will continue to grow as the mission progresses.
