Defining the coupled effects of cryogenic, space-radiation, and hypervelocity impact damamge on COPV's Project
Published By National Aeronautics and Space Administration

Summary
Description
The intent of the proposed effort is to investigate the detailed composite overwrapped pressure vessel (COPV) performance characteristics after being subject to irradiation, hypervelocity micro-meteor impact, and cryogenic environments. This will result in a safer, more reliable design for high performance COPVs. This intent will be achieved via empirical characterization of composite raw materials subsequent to exposure of the aforementioned environments. Phase I of this effort (NASA contract #NNM06AA56C) demonstrated a significant reduction in structural performance following exposure to various combinations of the aforementioned environments. This reduction in structural performance would seriously compromise the structural performance of any composite structure to be utilized in deep space applications. The data proposed in this effort would be extremely useful to NASA in what might be used in the upcoming CEV and CONSTELLATION missions. The aerospace and the commercial communities have shown significant interest in using filament wound COPVs for cryogenic applications. In addition there is serious consideration for using COPVs in deep space exploration which would sustain significant radiation exposure and possible impact damage. Constituent raw materials and existing COPV designs have not been characterized for the coupled effects of these applications and as such the safety margins for these applications are undefined. Therefore, the reliability of such usage is unknown.

GRID has had a successfully completed Phase I 'Mobile Online Intelligent Decision Support System' (MOIDSS). The system developed into a total solution that supports the ability to send and receive digital and analog data from sensors such as photography cameras, spectrometers, infrared and thermal scanners and other system sensors using the 'cube' computers and mobile Personal Data Adapters (PDA's). The data from the sensors can be accessed rapidly in real-time within a GIS using GRID 'geospatial-realty intelligent linking database' (GRILD) autonomously using GPS geospatial authentication. The system has successfully received data using wireless networking systems such as spread spectrum, UHF, and satellite communication systems. Using commercial-off-the-shelf (COTS) solutions allows a solution that is not proprietary and proven security biometric identification. This system uses GRID's customized software with partners ESRI and Leica Geosystems. The solution was designed with input from local first responders and facility managers. GRID is prepared to move to the next phase to enter the market with a valuable product.

Description
Dorris Reservoir is a vital component of the water infrastructure at the U.S. Fish and Wildlife Services U.S. FWS Modoc National Wildlife Refuge MNWR. This report intends to provide detailed bathymetric data collected efficiently with a Lowrance HDS Gen2 sonar fish finder and compare results to previously assessed bathymetry. A Lowrance HDS Gen2 sonar unit with an 83200 kHz transducer was used to survey Dorris Reservoir on during the peak annual water surface elevation on May 6th and 7th, 2013. Due to the timing of the study with the WSE about 6 feet below the spillway crest elevation, resulting in reduced area accessible by the sonar system, the waters edge at the time of the sonar survey was surveyed using a Trimble GeoXH with submeter accuracy after postprocessing. A Digital Elevation Model DEM of the reservoir was developed from reservoir bottom topographic data generated from the sonar survey and waters edge points in the geographic information system GIS ArcMap 10.2.

Mercury concentrations in gafftopsail catfish and other fishes in waters adjacent to Hobe Sound National Wildlife Refuge

Summary
Description
From September 2226, 1990, 20 gafftopsail catfish Bagre marinus and 3 other fish species n4 were collected from marine waters adjacent to Hobe Sound National Wildlife Refuge NWR, Florida. The fish were collected for mercury analysis of muscle tissue. Ninetyfive percent of the gafftopsail catfish n 19 had mercury levels that exceeded the Florida limitedconsumption advisory of 0.5 parts per million ppm, wet weight. Twentyfive percent n 5 exceeded Floridas noconsumption advisory of 1.5 ppm. Two other species, crevalle jack Caranx hippos n 2 and Atlantic croaker Micropogonias undulatus n 1, also had mercury concentrations exceeding the 0.5 ppm advisory. One black drum Pogonias cromis had a mercury concentration below advisory levels. Evaluation of mercuryweight and mercurylength relationships of the gafftopsail catfish did not provide mechanisms by which recreational fishermen could selectively retain individual fish that are low in mercury. The collection area between Hobe Sound and Peck Lake may be a marine environment that encourages bioconcentration of mercury in some marine fishes. Fish and wildlife trust resources may be at some risk when utilizing the food chain resources of these waters. Additional habitat and biota contaminant work is recommended.

CRED and partners: Environmental Monitoring of Coral Bleaching and Disease in the Hawaiian Islands; Belt Surveys of Coral Population and Disease Assessments at Maui, Hawaii in 2010

Summary
Description
The field data described herein are part of a joint NESDIS-NMFS project aimed at advancing the understanding of the occurrence, abundance, and outbreak of coral bleaching and disease in the Hawaiian Archipelago through expanded field surveys and in-situ and remotely-sensed temperature data. To this end Line-Point-Intercept (LPI), belt-transect surveys of coral population, and diseases quantitative assessments were conducted on MAUI in the MAIN HAWAIIAN ISLANDS by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC) and partners. At the specific sites, coral biologists conducted Line-Point-Intercept (LPI) and coral belt surveys, focused at quantifying the composition, relative abundance, density, and size-class distribution of the anthozoan and hydrozoan corals, as well as the condition and health state of the coral populations. The surveys were conducted along two consecutively-placed, 25m transect lines. The LPI surveys documented the composition of the coral reef community at 25 or 50cm intervals, for 50 or 100 points per transect. The belt width was 1-m wide (0.5-m on each side of the transect line), for community structure assessments, and 2-m wide (1.0-m on each side of the transect line), for coral condition and health surveys. Within each 25m transect, up to 15, 1.0-meter segments were surveyed, whereby in each segment, all coral colonies whose center fell within 0.5m of either side of the transect line were identified to the lowest taxonomic level possible (genus or species) and colony size visually estimated and binned by its maximum diameter in one of 7 size classes: 0-5cm, 5-10cm, 10-20cm, 20-40cm, 40-80cm, 80-160cm, or >160cm. When a coral colony exhibited signs of disease or compromised health, additional information was recorded including type of affliction (bleaching, skeletal growth anomaly, white syndrome, tissue loss other than white syndrome, trematodiasis, necrosis, other, pigmentation responses, algal overgrowth, and predation), severity of the affliction (mild, moderate, marked, severe, acute), as well as photographic documentation and sometimes tissue samples. Raw survey data included species presence and relative abundance, colony counts per taxon, size (width and length), mortality, predation, and health status. The surveyed area ranged from 25m2 to 50m2 per site.

The proposed research pursues a path for reducing structural weight, increasing structural performance, and reducing fabrication cost while also minimizing maintainability. The approach, which is a based on selective reinforcement, is a change in the basic design philosophy and will result in the development of a hybrid material form. The selective reinforcement approach allows the structural design requirements to define the material form. This is the reverse of the typical development flow path used for building structures. This backward path results in more efficient material forms that are of greater value to structural engineers. Specifically, the proposed effort will combine a metal matrix composite (MMC) prepreg tape feedstock with an advanced fiber placement process. The combination of these technologies will lead to enhanced metallic structures through selective reinforcement (SR), which consists of adding a high-performance material to structures to achieve local stiffening and strengthening.
