EM300 and EM3002D multibeam Data were collected from 13 June-08 July 2005 aboard NOAA Ship Hi'ialakai at Niihau, Penguin Bank, and Molokai in the Main Hawaiian Islands during cruise HI-05-04. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Surface sound velocity values were supplied by a Seabird SBE-45 MicroTSG and a SBE-38 remote temperature probe. Sound velocity corrections from a Seabird 911 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time and observed tides were applied in postprocessing. Horizontal accuracy is 5 m (differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from ~20-600m. Concurrent mapping at Niihau, Penguin Bank, and Molokai was done by the R/V AHI in water depths ranging from ~10-150m with the data set being AHI-05-04; metadata for AHI-05-04 are submitted separately.

Summary
Description
This dataset contains an ESRI Geotiff with 2 meter cell size representing the bathymetry of the a portion of the NPS's Salt River Bay National Historical Park and Ecological Reserve, north of St. Croix, 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 2/1/05 to 2/12/05. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9 as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster' was used to generate the final ESRI Geotiff.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.

Summary
Description
The Tropical Atmosphere Ocean (TAO) Array of 55 moored buoys spans the tropical Pacific from longitudes 165°E to 95°W between latitudes of approximately 8°S and 9°N. Moorings within the array measure surface meteorological and upper-ocean parameters and transmit most data in real time to shore via Service Argos. The array was part of the in-situ measurement portion of the Tropical Ocean-Global Atmosphere (TOGA) Program, a 10-year (1985 - 1994) study of climate variability on seasonal to interannual time scales, the most pronounced mode of which is the El Niño/Southern Oscillation (ENSO) phenomenon (McPhaden, 1993).

The proposed Phase I investigation will focus on the development of spacecraft systems required to obtain a sample from the nucleus of a comet, hermetically seal the sample within a capsule, and return the sealed sample to an orbiting spacecraft which can return the sample to Earth. A preliminary systems level concept has been developed. This concept will be refined during the proposed Phase I investigation, including proof-of-concept breadboards and analyses of critical subsystems.

Description
The AIRS Only Level 3 Monthly Gridded Retrieval Product contains standard retrieval means, standard deviations and input counts. Each file covers a calendar month. The mean values are simply the arithmetic means of the daily products, weighted by the number of input counts for each day in that grid box. The geophysical parameters have been averaged and binned into 1 x 1 deg grid cells, from -180.0 to +180.0 deg longitude and from -90.0 to +90.0 deg latitude. For each grid map of 4-byte floating-point mean values there is a corresponding 4-byte floating-point map of standard deviation and a 2-byte integer grid map of counts. The counts map provides the user with the number of points per bin that were included in the mean and can be used to generate custom multi-day maps from the daily gridded products. The thermodynamic parameters are: Skin Temperature (land and sea surface), Air Temperature at the surface, Profiles of Air Temperature and Water Vapor, Tropopause Characteristics, Column Precipitable Water, Cloud Amount/Frequency, Cloud Height, Cloud Top Pressure, Cloud Top Temperature, Reflectance, Emissivity, Surface Pressure, Cloud Vertical Distribution. The trace gases parameters are: Total Amounts and Vertical Profiles of Carbon Monoxide, Methane, and Ozone. The actual names of the variables in the data files should be inferred from the Processing File Description document. (The Shortname for this product is AIRS3STM).

AMPR data were collected at four microwave frequencies (10.7, 19.35, 37.1 and 85.5 GHz) for the period of 10 May 1998 through 08 June 1998. The FIRE-III/ACE mission is to study sea-ice melting, sea-ice drift, and other sea-ice properties. The experiment was focused on the Arctic Ocean in and near the Beaufort Sea off the northern coast of Alaska, in coordination with the ice-bound research ship Sheba.

Microwave Monolithic Integrated Circuits (MMIC) provide the technology base for miniaturization of microwave payloads in spacecraft. While MMIC chips are widely available for amplifiers, switches, converters, etc., there is only a limited supplier base for MMIC signal sources. Hittite has recognized the need and introduced a family of MMICs for phase-locking loops and phase-locked oscillators. Hittite's MMICs include; VCOs, frequency multipliers and dividers, programmable counters, phase-frequency detectors, and loop amplifiers. This proposal describes and approach of integrating many of those MMIC parts into a single chip for frequency synthesis without VCOs. This choice of the scale of integration will support the design architecture for frequency synthesizers with versatility of a wide range of operating frequencies. The selected design goals will allow signal generation from 100 MHz to 12 GHz. The phase noise floor of the synthesizer is expected to be ?150 dBC/Hz at 100 MHz offset. Design approaches for all component parts of the proposed MMIC are presented.

Investigation of Eggshell Thickness and Biochemical Indicators of Contaminant Exposure in Great Blue Heron (Ardea herodias) from Mason Neck National Wildlife Refuge
Published By US Fish and Wildlife Service, Department of the Interior
Issued about 9 years ago
Summary
Description
Mason Neck National Wildlife Refuge supports the largest great blue heron Ardea herodias rookery in the State of Virginia. The presence of bioaccumulative compounds such as polychlorinated biphenyls and DDT in fish collected from the Potomac River and tidal tributaries along the Refuge led to this study. The objective was to determine if there were any indications of pollutantinduced eggshell thinning or evidence of biochemical exposure to contaminants. We examined eggshell thickness and biomarkers of contaminant exposure in livers of embryos collected from the refuge and Coaches Island, a reference location in Chesapeake Bay. There was no evidence of eggshell thinning. Cytochrome P450 activity, measured as ethoxyresorufinOdealkylase EROD and benzyloxyresorufinOdealkylase BROD, was not significantly different in embryos from the two colonies. Biochemical indicators of oxidative stress can be reflected as changes in levels of reduced thiols, oxidized glutathione, and thiobarbituric reactive substances TBARS. Although there were significant differences in the levels of reduced glutathione GSH and total thiol TSH activities in the embryo livers, there were no statistically significant differences in TBARS, proteinbound sulthydryls PBSH, oxidized glutathione GSSG and the ratio of GSSG to GSH. In fact, the concentrations of GSH and TSH were higher in the Mason Neck birds relative to Coaches Island. Under conditions of increased oxidative stress at least one or more of the following would be expected: decreased concentrations of reduced thiols GSH and TSH, increased GSSG, and increased TBARS. In conclusion, we did not detect eggshell thinning or find evidence of a biochemical response to contaminant exposure in the Mason Neck great blue herons.
