Description

The 4 Layer Upper Atmosphere Temperature (UAT) Climate Data Record (CDR) dataset is a monthly analysis of the tropospheric and stratospheric data using temperature sounding microwave radiometers flown on polar-orbiting weather satellites providing an important record of upper atmosphere temperatures by merging data from the older Microwave Sounding Unit (MSU) and the new Advanced Microwave Sounding Units (AMSUs). The instruments measure the brightness temperature (tb) for each channel and corresponds to an average temperature of the atmosphere averaged over that channel's weighting function. Global average and global anomaly maps on a 2.5 x 2.5 degree resolution are produced from each month's data from both the MSU and the AMSU for over a 31 year period (1978-2011) for each channel (layer); the Temperature Lower Troposphere (TLT); the Temperature Middle Troposphere (TMT); the Temperature Troposphere/Stratosphere (TTS) ; the Temperature Lower Stratosphere (TLS). UAT 4 Layer MW data is important to continue into the future to ensure the existence of a high-quality record of atmospheric temperatures for climate change detection and climate model verification activities. The data are available in netCDF-4 file format with variables containing standard deviation, quality flags, and projection information and will be updated monthly as of FY 2013 CDR.

Description

The development of advanced methods for Microwave Enhanced Freeze Drying of Solid Waste (MEFDSW) is proposed. Methods for the recovery of relatively pure water as a byproduct of freeze drying will also be fully developed. The Phase II project will result in the design, assembly, thorough testing, and delivery of a technology demonstrator prototype which may be employed over a broad range of mission scenarios. The prototype system will recover water initially contained within the wastes and stabilize the residue with respect to microbial growth. The dry waste may then be safely stored or passed on to the next solid waste treatment process. Using microwave power in a closed microwave cavity, water-ice present in the frozen solid waste can be selectively and rapidly heated. This results in a more energy efficient lyophilization process, and therefore hardware based upon this technology will have a lower Equivalent System Mass (ESM) than currently available systems.

Description

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). This file is georeferenced to the earth's surface using the Universal Transverse Mercator, Zone 12, Meters, North American Datum 1983(NAD83), projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000. The Vertical Datum of this data set is North American Vertical Datum 1988 (NAVD88). The specifications for the vertical control of DFIRM data files are consistent with those required for mapping at a vertical accuracy of 2.4 feet or better.

Description

Under NASA Phase I funding, we have developed a system for the ball bearing fault detection and identification. Our system can effectively identify multiple fault modes related to the evolution of friction within the contact in the coated ball bearings. To detect bearing faulty modes, we have developed a new bispectrum and entropy analysis method to capture the faulty transient signals embedded in the measurements. To classify the fault modes, we further developed a set of stochastic models using hidden Markov model (HMM) and Gaussian mixtures. Test results using lab experiment data have shown that our system can identify coated ball bearing fault modes in near real-time. In Phase II, we will further develop and test our system developed in Phase I for spacecraft mechanical parts health monitoring and mitigating actions. A thorough understanding of the failure mechanisms of the moving parts will emerge by the end of the Phase II effort, as well as the methodology to prevent catastrophic failure while in orbit. Algorithms developed in Phase I/II will be implemented in C/C++. Effort will be focused on the accuracy, autonomous, speed and efficiency of the system. The Boeing Company has teamed with us for Phase II effort.

Description

In order to test hypotheses about groundwater flow under and into Chesapeake Bay, geophysical surveys were conducted by U.S. Geological Survey (USGS) scientists on Chesapeake Bay and the Potomac River Estuary in September 2006. Chesapeake Bay resource managers are concerned about nutrients that are entering the estuary via submarine groundwater discharge, which are contributing to eutrophication. The USGS has performed many related studies in recent years to provide managers with information necessary to make informed decisions about this issue. The research carried out as part of the study described here was designed to help refine nutrient budgets for Chesapeake Bay by characterizing submarine groundwater flow and discharge of groundwater beneath part of the mainstem and a major tributary, the Potomac River Estuary.

Description

The Office of the Legal Adviser publishes the annual Digest of United States Practice in International Law to provide the public with a historical record of the views and practice of the Government of the United States in public and private international law. "In his introduction to the 2001 volume, then Legal Adviser William H. Taft IV stated in part: "2001 will likely prove to have been a watershed in the development of international law. In this field, as in so many other ways, the tragic, traumatic events of September 11 altered the landscape of U.S. practice. Issues of use of force, self-defense, and counter-terrorism, which have always been important, have posed unforeseen challenges in unanticipated contexts. Policy makers have been confronted by new questions related to humanitarian law, the law of war, and international criminal law. The various domestic and international responses to terrorism, including economic and trade sanctions, the freezing and seizing of assets, claims for compensation, and civil litigation, have each generated new and unique problems, to which the legal responses continue to develop. "At the same time, 2001 witnessed many other significant developments not directly related to the events of September 11, both through United States participation in international fora and developments in the application of international law in the United States. These cover the full range of topics in international legal practice, from treaties to consular affairs, the environment, and private international law. . . ."

Description

Semipermeable devices SPMDs were deployed in wetlands along a railroad rightofway at the Cokeville Meadows National Wildlife Refuge, Lincoln County, Wyoming to determine if hydrocarbons from discarded creosotetreated railroad ties have leached into the wetlands in quantities harmful to fish and wildlife. SPMDs were deployed in three wetlandtie sites and one reference site. Two SPMD deployment devices, each containing two SPMDs, were deployed at three wetland sites containing railroad ties on May 29, 2002. One SPMD deployment device was submerged in the water approximately one meter from the railroad ties and the second was placed approximately five meters from the railroad ties. SPMDs were deployed in water 0.5 to 1 meter in depth. One SPMD deployment device containing two SPMDs was placed in a railroad rightofway wetland without railroad ties reference site. The SPMDs were retrieved approximately 30 days later on July 2, 2002. One sediment sample was collected at each of 4 wetland sites containing old railroad ties and one reference site and analyzed for aromatic and aliphatic hydrocarbons. Thirtyfour wetland sites along the railroad rightofway contained railroad ties. A total of 784 railroad ties were observed in these wetlands with an average of 21 railroad ties at each site. Only two of the 34 sites were located in rightofway adjacent to a refuge tract. The two refuge sites contained 11 and 20 railroad ties, respectively. Hydrocarbon concentrations were below concentrations known to adversely affect sedimentdwelling organisms. Aromatic hydrocarbon concentrations from the SPMDs were extrapolated to water concentrations and all aromatic hydrocarbons were below chronic toxicity levels for aquatic invertebrates.

Description

A survey of the marine communities of Midway Atoll harbor and surrounding lagoon was conducted at 12 sites from September 5 to 9, 1998. The primary focus of these surveys was the invertebrates of the fouling communities present on artificial substrates. Occurrence of reef fishes at each site was also recorded, and algae was collected and identified from four stations. A total of 444 taxa were identified (47 algae, 316 invertebrates, and 81 fishes) from all stations. Approximately 250 invertebrate and 35 algae species are considered new records for Midway Atoll. All fishes observed were previously recorded from the atoll. Only three invertebrates identified in this survey are considered to be nonindigenous species in the Hawaiian Islands. One introduced bryozoan, Amathia distans, dominated the fouling communities at most stations where artificial substrates were available. Another introduced bryozoan, Schizoporella errata, was also common at the same stations. A non indigenous barnacle, Chthamalus proteus, recently introduced from the Caribbean, was common on pier pilings inside Midway harbor. No introduced invertebrates were present in natural habitats. The introduced snapper, Lutjanus kasmira, was also present along the reef outside the lagoon. The threat to the native reef community by established non-indigenous species is considered minimal. The presence of these introduced species at Midway, especially Chthamalus proteus, suggests that vectors of future, potentially more deleterious introductions exist. Transport of these introductions was most likely as fouling on ship bottoms, but other sources of introductions, such as ballast water carried in ships, should be guarded against to protect the relatively pristine reefs of Midway Atoll.
