Airborne Synthetic Aperture Radar (AIRSAR) is a side-looking imaging radar that is able to collect data irrespective of daylight or cloud cover. The AIRSAR instrument was operated in two modes over each Cold Land Processes Field Experiment (CLPX) Meso-cell Study Area (MSA). In the first mode (POLSAR), polarimetric radar data were collected at P-, L-, and C-bands. In the second mode (TOPSAR), cross-track interferometry data were collected at C-band and L-band. The CLPX AIRSAR mission flew on a DC-8 aircraft at 8 km altitude over the three MSAs at Rabbit Ears, North Park, and Fraser. 171 flight lines (87 TOPSAR and 84 POLSAR) were flown in February, March, and September of 2002 and in March 2003. The NASA CLPX is a multi-sensor, multi-scale experiment that focuses on extending a local-scale understanding of water fluxes, storage, and transformations to regional and global scales. Within a framework of nested study areas in the central Rocky Mountains of the western United States, ranging from 1-ha to 160,000 km2, intensive ground, airborne, and spaceborne observations are collected. Data collection focuses on two seasons: mid-winter, when conditions are generally frozen and dry, and early spring, a transitional period when both frozen and thawed, dry and wet conditions are widespread.

In certain markets, live fish can be sold for substantially higher prices than fresh dressed fish. A significant live-haul industry has developed in the U.S. and fish are commonly hauled 1,500-2,000 miles (25-30 hours) to market. The most common species hauled are tilapia, channel catfish, and rainbow trout; a smaller amount of marine rockfish, hybrid striped bass, and carp are also hauled. The most significant advancement in hauling technology in the last 20 years has been the use of bottled oxygen gas or liquid oxygen to maintain adequate dissolved oxygen levels. These types of systems can maintain significantly higher DO levels than systems using air. Some common stressors include harvest and loading procedures (pumping or out of water transfer), shaking as the transport vehicle is moving, low frequency sound from the vehicle and water treatment systems, crowding, and poor water quality (high ammonia and carbon dioxide levels, low dissolved oxygen), high light levels, or extreme water temperature. The physical shape and construction of the hauling unit may have an important impact on localized low DOs, physical damage to the fish, and survivability. Very little information has been published on the chemical and physical conditions in transport systems during long-distance transport and this limited data may not be representative of current commercial systems. This research will be conducted with NWFSC staff in cooperation with private fish farmers in the Pacific Northwest. Specific sub-objectives will include the following: (1) Documentation of water quality during transport and impact on mortality and product quality (2) Design of efficient aeration systems for oxygen transfer and carbon dioxide stripping (3) Determination of the impact of transport tank design and aerator type on the thermal balance during hauling. The impact of this project will be increased survival and product quality of transported fish as a result of adopting the recommended protocols and utilization of the models. Project outputs will include peer-reviewed publications, popular publications, and conference presentations. The oxygen transfer coefficient (KLa) will be determined by deaeration with nitrogen gas followed by aeration (0.60 slpm) using a YSI ProODO dissolved oxygen meter. The KLa value will be computed from the ASCE Standard for the Measurement of Oxygen Transfer in Clean Water http://cedb.asce.org/cgi/WWWdisplay.cgi?156576The measure KLa values will be reported at 20C using a theta = 1.047.

We propose to develop and commercialize a new type of low-stress iridium (Ir) X-ray mirror coating technology that can be used for the construction of high-resolution X-ray telescopes comprising thin-shell mirror substrates, such as the Soft X-ray Telescope (SXT) currently being developed for the Constellation-X mission. The urgent need for low-stress Ir coating technology is driven by the current limitations on telescope angular resolution resulting from substrate distortions caused by conventional reflective Ir coatings that have high stress. In particular, we have measured film stresses in excess of 3 GPa in the case of 30 nm Ir films deposited by conventional magnetron sputtering techniques. The distortions in thin glass mirror shells (such as those suitable for the Constellation-X SXT) resulting from these extremely large coating stresses presently make the largest contribution to the SXT telescope imaging error budget, of order 10 arcsec or more. Consequently, it will be difficult, if not impossible, to meet the imaging requirements of Constellation-X, or other future high-resolution X-ray missions, unless high-quality Ir coatings having significantly lower stresses can be developed. The development of such coatings is precisely the aim of our proposal.

In this phase II SBIR we will design, build, test, and deliver new scanning based micro-ladar sensors with unprecedented small size, weight, and power (SWaP), thereby enabling scanning LADAR deployment on previously inaccessible platforms such as satellites. The system will range out to > 1 km, have high frame rates, high resolution (up to 500 x 500), high range accuracy (<5 cm), weigh less than a kg, be constructed from space deployable technologies with no-moving parts. The enabling technology for this Micro-LADAR system is a combination of two new electro-optic laser scanning technologies: high speed refractive continuous scanners with a 60&#176;x15&#176; field of view (FOV) and diffractive-waveplate discrete or step-wise scanners to boost the total FOV (ultimately up to unthinkable angles such as 120&#176;x120&#176;). The results will be a very low-power, long-life (no moving parts), radiation hard, micro-LADAR.

MMIC technology provides the technology base to reduce the size and weight of microwave and millimeter wave (MMW) equipment on board airborne and space-based platforms. Signal sources at MMW frequencies, however, have not been available in MMIC form widely. Hittite has developed a family of MMIC products to implement complete phase-locked synthesizers in using MMIC and mixed-signal ICs and demonstrated miniaturized frequency synthesizers representing size reduction of several orders of magnitude without sacrificing performance. Based on recent success in demonstration of critical MMICs and ICs, Hittite proposes to apply its novel MMIC concept to design MMW signal sources for application in earth monitoring sensors. Two different synthesizer architecture, one direct and one indirect, are proposed as candidate approaches. In both cases, frequency synthesis will take place at about 1/8 of the output frequency and then translated up to the final output with a fixed tone. The proposed approach relies on components operating at lower frequencies for better phase noise performance, and the method is applicable to generation of higher frequencies. The proposed program will lead to a family of novel miniaturized MMIC products for commercial communications.

Summary
Description
Bathymetry for Tomales Bay was derived from three surveys containing22,020 soundings. Five older, less accurate, overlapping surveys wereomitted before tinning. The average separation between soundings was 37meters. The three surveys used dated from 1993 and 1994. The total range ofsounding data was 1.5 meters to -18.9 meters at mean low water. A mean highwater value of 1.1 meters was assigned to the shoreline. Two points were foundthat were not consistent with the surrounding data and were removed priorto tinning. DEM grid values outside the shoreline (on land) wereassigned null values (-32676).Tomales Bay has four 7.5 minute DEMs and a single one degree DEM. The1 degree DEMs were generated from the higher resolution 7.5 minuteDEMs which covered the estuary. A Digital Elevation Model (DEM)contains a series of elevations ordered from south to north with theorder of the columns from west to east. The DEM is formatted as oneASCII header record (A- record), followed by a series of profilerecords (B- records) each of which include a short B-record headerfollowed by a series of ASCII integer elevations (typically in unitsof 1 centimeter) per each profile. The last physical record of theDEM is an accuracy record (C-record).The 7.5-minute DEM (30- by 30-m data spacing) is cast on theUniversal Transverse Mercator (UTM) projection. It provides coveragein 7.5- by 7.5-minute blocks. Each product provides the samecoverage as a standard USGS 7.5-minute quadrangle but the DEMcontains over edge data. Coverage is available for many estuaries ofthe contiguous United States but is not complete.

Five Year Mean Bottom to Surface Temperature Differences in the Northern Gulf of Mexico for 2005 through 2009
Published By National Oceanic and Atmospheric Administration, Department of Commerce
Issued oltre 9 anni ago
Summary
Description
These images were created by combining the estimates of the mean bottom to surface temperature differences to produce seasonal representations for winter, spring, summer and fall. Winter includes the months of January, February and March; spring includes the months of April, May and June; summer includes the months of July, August and September; fall includes the months of October, November and December. Estimates of bottom to surface temperature differences (Delta t) were originally obtained from the Naval Research Laboratory at the Stennis Space Center (NRL/SSC). NRL/SSC derived these estimates from a reanalysis of NRL/SSC Intra-Americas Sea Ocean Nowcast/Forecast System (IASNFS). The NRL IASNFS is a 3-dimensional circulation model based on the Navy Coast Model (NCOM) (Ko et al. 2003). The model has a 1/24 degree resolution or about ~5.8 km at the northern Gulf of Mexico and 40 vertical layers. It covers the Gulf of Mexico and Caribbean Sea and uses Navy Global NCOM for the open boundary conditions. IASNFS assimilates satellite altimeter data from GFO, Jason-1, ERS-1/2, EnviSat and TOPEX and sea surface temperature from NOAA AVHRR and MODIS (Ko et al. 2008). The surface forcing includes wind, heat fluxes and sea level air-pressure derived from Navy operational global weather forecast model NOGAPS. The temperature differences were calculated from temperature at surface layer and at bottom layer or to 100 m depth and interpolated onto a 2 minute grid for northern Gulf Coast.

Summary
Description
This dataset is one of eight datasets produced by this study. Four of the datasets predict the probability of detecting atrazine and(or) desethyl-atrazine (a breakdown product of atrazine) in ground water in Colorado; the other four predict the probability of detecting elevated concentrations of nitrate in ground water in Colorado. The four datasets that predict the probability of atrazine and(or) desethyl-atrazine (atrazine/DEA) are differentiated by whether or not they incorporated atrazine use and whether or not they incorporated hydrogeomorphic regions. The four datasets that predict the probability of elevated concentrations of nitrate are differentiated by whether or not they incorporated fertilizer use and whether or not they incorporated hydrogeomorphic regions. Each of the eight datasets has its own unique strengths and weaknesses. The user is cautioned to read Rupert (2003, Probability of detecting atrazine/desethyl-atrazine and elevated concentrations of nitrate in ground water in Colorado: U.S. Geological Survey Water-Resources Investigations Report 02-4269, 35 p., http://water.usgs.gov/pubs/wri/wri02-4269/) to determine if he(she) is using the most appropriate dataset for his(her) particular needs. This dataset specifically predicts the probability of detecting elevated concentrations of nitrate in ground water in Colorado with hydrogeomorphic regions not included and fertilizer use included. The following text was extracted from Rupert (2003). Draft Federal regulations may require that each State develop a State Pesticide Management Plan for the herbicides atrazine, alachlor, metolachlor, and simazine. Maps were developed that the State of Colorado could use to predict the probability of detecting atrazine/DEA in ground water in Colorado. These maps can be incorporated into the State Pesticide Management Plan and can help provide a sound hydrogeologic basis for atrazine management in Colorado. Maps showing the probability of detecting elevated nitrite plus nitrate as nitrogen (nitrate) concentrations in ground water in Colorado also were developed because nitrate is a contaminant of concern in many areas of Colorado. Maps showing the probability of detecting atrazine/DEA at or greater than concentrations of 0.1 microgram per liter and nitrate concentrations in ground water greater than 5 milligrams per liter were developed as follows: (1) Ground-water quality data were overlaid with anthropogenic and hydrogeologic data by using a geographic information system (GIS) to produce a dataset in which each well had corresponding data on atrazine use, fertilizer use, geology, hydrogeomorphic regions, land cover, precipitation, soils, and well construction. These data then were downloaded to a statistical software package for analysis by logistic regression. (2) Relations were observed between ground-water quality and the percentage of land-cover categories within circular regions (buffers) around wells. Several buffer sizes were evaluated; the buffer size that provided the strongest relation was selected for use in the logistic regression models. (3) Relations between concentrations of atrazine/DEA and nitrate in ground water and atrazine use, fertilizer use, geology, hydrogeomorphic regions, land cover, precipitation, soils, and well-construction data were evaluated, and several preliminary multivariate models with various combinations of independent variables were constructed. (4) The multivariate models that best predicted the presence of atrazine/DEA and elevated concentrations of nitrate in ground water were selected. (5) The accuracy of the multivariate models was confirmed by validating the models with an independent set of ground-water quality data. (6) The multivariate models were entered into a geographic information system and the probability GRIDS were constructed.

The NOAA Hypoxia Watch project provides near-real-time, web-based maps of dissolved oxygen near the sea floor over the Texas-Louisiana continental shelf during a period that extends from early June to mid-July. The NOAA National Marine Fisheries Service Mississippi Laboratories at Pascagoula and Stennis Space Center and the NOAA National Coastal Data Development Center (NCDDC) at Stennis Space Center began the Hypoxia Watch project in 2001. Scientists aboard the NOAA Research Vessel Oregon II measure seawater properties, such as water temperature, salinity, chlorophyll, and dissolved oxygen at each of approximately 240 locations as the Oregon II cruises the waters south of Pascagoula, MS and then makes its way from Brownsville, Texas, to the mouth of the Mississippi River. A scientist aboard the ship processes the measurements from electronic dissolved oxygen sensors, checks the measurements periodically with chemical analyses of the seawater, then sends the data by e-mail to NCDDC at Stennis Space Center approximately every three to five days. Physical Scientists at NCDDC transform the dissolved oxygen measurements into contour maps, which identify areas of low oxygen, or hypoxia. During the 6-week cruise, as the data is received from the ship, NCDDC generates new maps and immediately publishes them on the web. The first map will usually cover an area off the Mississippi coast, successive maps will add areas of the continental shelf from Brownsville to Galveston, and the final map will usually cover the entire Texas-Louisiana-Mississippi coast. Maps are published every three to five days from approximately June 10 to July 20.

Diamond turning is able to produce highly aspheric visible quality optics which can be easily aligned. Very large optical systems such as OWL and EUSO are impossible to produce using diamond turning because machines capable of machining 3 meter size optics do not exist. This is because no air bearing spindle is available with load capacity for the weight of the optical component and the required heavy part holding fixture. Large diamond turning machines today have oil hydrostatic spindles which are not useful for very large diamond turning because of excessive heat generation when this type bearing is large enough to have load capacity for very large optics. The viscosity of air is more than three orders of magnitude less than oil, therefore the heating of large diameter air bearings is very small. The extreme precision required for air bearings is in the realm of optical tolerances. Air bearings utilizing two metal surfaces in close contact fail in large sizes because metals weld together in the event of the slightest touch. Porous graphite air bearings do not friction weld in the event of the spindle bearing surface contacting the bearing journal surface. The porous graphite flow structure provides uniform flow to damp the instability that is a problem with air hydrostatic bearings. This proposal combines porous graphite air bearing technology with optical fabrication methods to build a new type of vertical axis air bearing for diamond turning machine use. The goal of this Phase I SBIR effort will be to demonstrate the technology with a sub-scale air bearing spindle. The Phase I and II efforts will be coordinated with internal R&D efforts of DOS and Moore Tool Co. The object of a Phase III proposal will be to integrate an air bearing spindle in a 3 meter capacity diamond turning machine that will have a load capacity of approximately 89,000 Newton (20,000 lb.) and a rotational speed capability of 1000 rpm.
