Popis
The proposed innovation builds on the successes of the Phase I program by integrating our direct oxidation membrane electrode assembly (MEA) into a monolithic solid oxide fuel cell stack (SOFC) capable of long-term operation on methane or syngas. This innovation is significant because it will contribute to durable, cycle-able simple SOFC systems to meet the needs for NASA and commercial customers. ITN's Phase II strategy addresses the technical hurdles that limit the long-term durability and thermal cycling of state-of-the-art SOFCs operating on methane fuel, including : <ul> <li>Matching stack components for coefficient of thermal expansion </li> <li>Reducing stack mass</li> <li>Stack sealing</li> <li>Reducing anode degradation, and </li> <li>Reducing operating temperatures.</li> </ul> With this innovation, we project that the proposed SOFC stack will be capable of operating without degradation for more than the targeted 2500 hours and will operate without power density degradation after 50 start-up and shut-down cycles. By utilizing the direct-oxidation membrane electrode assemblies developed in the phase I program, the thermodynamic efficiencies from fuel source to DC output should exceed 70%. Higher efficiencies translate to lower cooling requirement as obtained by way of conduction through the stack to a radiator exposed to space and/or by anode exhaust flow.

Land-Ocean Interaction Study (LOIS) investigated sediments, nutrients and contaminants from the watershed to the edge of the coastal shelf. The programme quantified and modelled fluxes of these materials and investigated how they are transformed as they move through river catchments, estuaries and coastal seas. This highly interdisciplinary study considered riverine, atmospheric, estuarine, coastal and shelf processes. The work included a major geological study of the sedimentary record across the coastal zone to determine how fluxes of material have influenced sea level, climate and land use.

Popis
This project is a cooperative effort among 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 and hyperspectral imagery. Aerial photographs were acquired for the Main Eight Hawaiian Islands Benthic Mapping Project in 2000 by NOAA Aircraft Operation Centers aircraft and National Geodetic Survey cameras and personnel. Approximately 1,500, color, 9 by 9 inch photos were taken of the coastal waters of the Main Eight Hawaiian Islands at 1:24,000 scale. Specific sun angle and maximum percent cloud cover restrictions were adhered to when possible during photography missions to ensure collection of high quality imagery for the purpose of benthic mapping. In addition, consecutive photos were taken at 60 percent overlap on individual flight lines and 30 percent overlap on adjacent flight lines to allow for orthorectification and elimination of sun glint. 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. The AURORA hyperspectral imaging system collected 72 ten nm bands in 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. The digital scans of aerial photos and hyperspectral imagery were orthorectified to eliminate sources of spatial distortion. With these orthorectified images 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.

Bathythermograph data were collected from the SPENCER within a 1-mile radius of Ocean Weather Station B (5600N 05100W) and in transit. Data were collected by the United States Coast Guard from 25 September 1967 to 29 October 1967. 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 the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

Objectives are to: 1) perform multibeam mapping of transitional and deepwater habitats in Hudson Canyon (off New Jersey) with the National Institute of Undersea Science and Technology (NIUST) AUV Eagle Ray. About one half of the shelf portion of the canyon was mapped with Eagle Ray between 2007 aboard Ronald H. Brown and 2008 aboard Henry B. Bigelow. We seek to complete the mapping of the shelf segment of the Hudson Canyon on this cruise; 2) perform visual ground truthing of areas up to 1,000 m deep in Hudson Canyon using the NIUST AUV Mola Mola. In particular, we will be investigating ravines in canyon walls mapped by Eagle Ray for vulnerable deepwater coral and sponge communities, tilefish pueblo villages, and suspected areas of methane blowouts in the canyon bottom for vulnerable chemosynthetic communities. Such vulnerable communities may be at risk due to overlap with deepsea red crab, witch flounder, and/or monkfish distributions. The intention is to detect and locate vulnerable communities and also to gain experience for development of protocols for further exploration for vulnerable deepwater habitats in canyon and slope areas; 3) perform a series of CTD/rosette sampler casts down the canyon to a maximum depth of about 1,200 m in the canyon axis. This will provide a near-synoptic, 3-dimensional view of water mass interaction around Hudson Canyon and allow collection of water samples at multiple depths for dissolved methane analysis. The latter will help resolve the source of elevated methane previously detected in deep water within Hudson Canyon. Possible discovery of a local seep raises the possibility of a chemosynthetic community supported by that feature; and 4) collect ME70 multibeam sonar data for purposes of benthic mapping in order to resolve some issues encountered during summer 2008 cruises for that purpose.

Terrapoint collected LiDAR for 197 square miles covering five islands off the coast of Los Angeles, California. These islands are part of the Channel Islands National Park and consists of San Miguel Island, Santa Rosa Island, Santa Cruz Island, Anacapa Island, and Santa Barbara Island. The nominal pulse spacing for this project was better than 0.7 meters. This project was collected with a sensor which collects waveform data and provides an intensity value for each discrete pulse extracted from the waveform. GPS Week Time, Intensity, Flightline and echo number attributes were provided for each LiDAR point. Dewberry used proprietary procedures to classify the LAS according to USGS ARRA specifications: 1-Unclassified 2-Ground 7-Noise 9-Water 10-Ignored Ground due to breakline proximity. Dewberry produced 3D breaklines, seamless DSMs, and seamless hydro flattened DEMs for the 204 tiles (2000 m x 2000 m) that cover the project area. Area mapped by island is as follows: Santa Barbara Island-1 sq. mi. Anacapa Island-1 sq. mi. San Miguel Island-15 sq. mi. Santa Rosa Island-83 sq. mi. Santa Cruz Island-97 sq. mi. Two UTM zones cover the Channel Islands. The islands delivered per each UTM zone are as follows (please note that Santa Rosa Island was delivered in both UTM zone 10 and UTM zone 11): UTM Zone 10: Santa Rosa Island San Miguel Island UTM Zone 11: Santa Barbara Island Santa Rosa Island Santa Cruz Island Anacapa Island The NOAA Office for Coastal Management received the data in UTM Zones 10 and 11. The data were converted to geographic coordinates and from NAVD88 heights to ellipsoid heights using GEOID09. These files were converted for data storage and Digital Coast provisioning purposes.

This dataset contains counts of adult and juvenile (non-pup) Steller sea lions on rookeries and haul-outs in Alaska made between 1904 and 2014. Non-pup counts have been conducted throughout the year. Breeding season (June-mid July) non-pup counts are used for population trend analysis, while counts at other times are used for analyses of distribution and for other purposes. Non-pups are counted from the ground (by walking along the rookery), from cliff-side overlooks, and from aerial imagery (oblique and vertical orientation). Non-pup counts represent only a fraction of the total number of animals that may use a site. Sea lions haulout less frequently in winter than in summer; thus, winter counts represent a smaller fraction of the total population than summer counts.
