Summary
Description
The National Wildlife Refuge Systems 150 million acres in over 500 refuges representdiverse landscapes with different capacities to provide ecosystem goods and services to society.Natural processes associated with management of national wildlife refuges provide benefits tolocal communities by sustaining production of specific goods and services that are useful topeople. Estimated economic values of these services, such as those presented in this report, can be used to compare refuges in different locations and under different management, climatic, or socioeconomic conditions. Our estimates of economic benefits from natural ecosystems serve as complements to economic impact analyses, such as the FWSs Banking on Nature studies Carver and Caudill 2007. This report presents the methods and results from Phase I of our research project. In this report we compare wetlands on four national wildlife refuges to illustrate how existing data can be used to estimate the average annual economic benefits of specific ecosystem services from different types of wetlands. The four sites are Arrowwood National Wildlife Refuge NWR, North Dakota; Blackwater NWR, Maryland; Okefenokee NWR, Georgia; and Sevilleta and Bosque del Apache NWRs, New Mexico. These four sites were selected to contrast major types of wetlands in terms of physical and social parameters that influence the values of different ecosystem goods and services. We present multiple approaches to assessing ecosystem services benefits. For each of the four refuges, we first consider a purely qualitative assessment of the relative magnitudes of different ecosystem service benefits provided by each refuge. This approach proves to be the most inclusive in terms of our ability to consider ecological data specific to the refuge, and provides a useful tool for broad assessments and comparisons across refuges. However, it does not lead to quantitative estimates of ecosystem service benefits. For these estimates, we use two different benefit transfer techniques: 1 a metaanalysis benefit transfer to estimate the economic values of storm protection, water quality provisioning, and support for nursery and habitat for commercial fishing species; and 2 a point transfer approach to estimate the value of stored carbon. Our results suggest that refuge size and the sociodemographic characteristics of the surrounding region are important determinates of the estimated per acre value of wetlands in providing ecosystem services. Consistent with economic theory, larger refuges in areas with lower population density tend to have lower per acre values. However, these interaction effects between wetland size, population size and preferences, and ecosystem service values need to be further studied. Our results are an approximation of consumers aggregate willingness to pay to obtain the service provided by the wetlands of a particular NWR. Decision makers can use these numbers to understand how a population might be impacted by a change in distribution of wetlands across a landscape. The most straightforward application of the method we follow concerns estimating the net economic value of a change in an ecosystem service due to a management action which changes a wetland from one type to another. This report represents Phase I of our efforts to estimate the ecosystem service benefits of the National Wildlife Refuge System. The primary focus of the second phase will be the development of a metaanalysis benefit transfer model specifically tailored toward wetlands in National Wildlife Refuges.

The second release of Version 003 OMI/Aura Level-2 Total Column Ozone Data Product OMDOAO3 is now available ( http://disc.gsfc.nasa.gov/Aura/OMI/omdoao3_v003.shtml ) from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) for the public access. The data was processed in late 2011 using Algorithm or PGE version 1.2.3 and released in March 2012. OMI provides two total column ozone products based on two different algorithms. This level-2 global total column ozone product at the pixel resolution (13x24 km at nadir), is based on the Differential Absorption Spectroscopy (DOAS) fitting technique that essentially uses the OMI visible radiance values between 331.1 and 336.1 nm. In addition to the total ozone column this product also contains some auxiliary derived and ancillary input parameters e.g. ozone slant column density, ozone ghost column density, air mass factor, scene reflectivity, radiance over the DOAS fit window, root mean square of DAOS fit, cloud fraction, cloud radiance, cloud pressure, terrain height, geolocation, viewing angles and quality flags. (The shortname for this Level-2 OMI total column ozone product is OMDOAO3) The lead scientist for this product is Dr. J. Pepijn Veefkind (Veefkind@knmi.nl). OMDOAO3 product files are stored in Hierarchical Data Format (HDF-EOS5). Each file contains data from the day lit portion of an orbit (approx 53 minutes) and is roughly 10.978 MB in size. There are approximately 14 orbits per day thus the total data volume is approximately 150 GB/day. A list of tools for browsing and extracting data from these files can be found at: http://disc.gsfc.nasa.gov/Aura/tools.shtml A 'Readme' document containing brief algorithm description and known data quality related issues and file spec are provided by the OMDOAO3 Algorithm lead (see http://disc.gsfc.nasa.gov/Aura/OMI/omdoao3_v003.shtml).
Near-real-time surface ocean velocities derived from HF-radar stations located along coastal waters of Puerto Rico/Virgin Islands, eastern US/Gulf of Mexico, Hawaii and western US during May 2015 (NCEI Accession 0131932)

Summary
Description
This archival package contains near-real-time ocean surface velocities, also known as total vector velocities, derived from HF radar stations. The velocities are arranged in a horizontal latitude/longitude grid. Measured velocities are indicative of the upper 0.3 - 2.5 meters of the ocean depending on the operating frequency and the vertical velocity profile of the water column. Data are in netCDF and velocities are reported in the Climate and Forecast (CF) compliant variables, surface_eastward_sea_water_velocity and surface_northward_sea_water_velocity. NDBC, which with SIO assembles data from the IOOS HF Radar Network, submits these data monthly to NCEI as part of NCEI's Integrated Ocean Observing System Data Assembly Centers (IOOS DACs) Data Stewardship Program. Remote sensing of ocean surface velocity from shore-based HF radar sites bridges the operational observational gap between point samples obtained from in-situ sampling and synoptic scale relatively low resolution data obtained from satellites by providing continuous mesoscale coverage at relatively high resolution near the coast.

Summary
Description
Oceanographic Station Data were collected from bottle casts from the MELVILLE from 30 August 1973 to 08 June 1974. Data were collected by the Scripps Institution of Oceanography (SIO) as part of the International Decade of Ocean Exploration / Geochemical Ocean Study (IDOE/GEOSECS). Data were processed by NODC to the NODC standard Oceanographic Station Data (SD2) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/sd2.html. The Oceanographic Station Data format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity, but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t), sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.

Selenium in the ecosystem of the grassland area of the San Joaquin Valley: Has the problem been fixed?
Published By US Fish and Wildlife Service, Department of the Interior
Issued about 9 years ago
Summary
Description
The West Grassland area consists of 26,690 hectares of federal, state, and private native pasture and seasonal wetlands representing the largest tract of waterfowl habitat in the San Joaquin Valley of California. Subsurface tile drains, designed to remove saline water from the root zone of agricultural crops, have been installed in irrigated farmland of the western San Joaquin Valley since 1960. Although subsurface drainage water contains elevated concentrations of selenium as well as other naturally occurring trace elements and salts, it was used for wetland management for several decades. In the early 1980s it was discovered that selenium in the drainwater caused malformations and reproductive failure in waterfowl at the Kesterson National Wildlife Refuge. Selenium levels in waterfowl tissue where also high enough to warrant the issuance of human health advisories. Beginning in 1985, Agricultural drainwater was no longer applied directly to wetlands, but wetland water supply channels continued to be used periodically to convey agricultural drainwater through wetland areas to the San Joaquin River. Since September of 1996 a new drainwater management program the Grassland Bypass Project GBP, has been diverting the agricultural drainwater through the San Luis Drain, thus removing drainwater from Grassland area channels that are used to supply wetlands. The purpose of this project is to provide a timely assessment of the degree to which drainwater management initiatives have indeed reduced toxicological risk to wildlife in the area. Selenium levels in most bird eggs 93.5 were below the 6.0 ugg level of concern. Somewhat elevated selenium concentrations in fish, tadpole, and invertebrate samples collected mainly from ditches and canals indicate that the selenium problem in the South Grassland area has improved but remains unresolved. Full recovery of the Grassland area wetland ecosystems may not yet be fully realized for two potential reasons: A recycling of a persistent reservoir of residual selenium, and B continuing input of additional selenium into the ecosystems.

The objective of the Phase I SBIR project is to develop sensors that can discriminate the presence of combustible gases like oxygen (O2) in hydrogen (H2) or H2 in O2 backgrounds. These sensors will meet NASA applications for on-orbit crew and mission safety. Currently, H2 and O2 are produced by electrolysis of water. The O2 is used in the environmental control and life support systems (ECLSS) of spacecraft while the hydrogen is vented. H2 is a flammable gas while oxygen aids in combustion. InnoSense LLC (ISL) will utilize its Chemical Fingerprint (TM) sensor array fabrication technology in Phase I to engineer a miniature device with multi-analyte detection capability. The Phase I working model would be evaluated to demonstrate NASA use potential. Upon fine-tuning various parameters in Phase II, the system performance will be tested with a prototype hardware. ISL has received technology endorsement letter from a prime contractor in the NASA application area. For assuring success of this project, ISL has assembled a technical team with a cumulative 60 person-years of experience in developing commercially viable sensor systems.
