Description
The Integrated Biosphere Simulator (or IBIS) is designed to be a comprehensive model of the terrestrial biosphere. Tthe model represents a wide range of processes, including land surface physics, canopy physiology, plant phenology, vegetation dynamics and competition, and carbon and nutrient cycling. The model generates global simulations of the surface water balance (e.g., runoff), the terrestrial carbon balance (e.g., net primary production, net ecosystem exchange, soil carbon, aboveground and belowground litter, and soil CO2 fluxes), and vegetation structure (e.g., biomass, leaf area index, and vegetation composition). IBIS was developed by Center for Sustainability and the Global Environment (SAGE) researchers as a first step toward gaining an improved understanding of global biospheric processes and studying their potential response to human activity [Foley et al. 1996]. IBIS was constructed to explicitly link land surface and hydrological processes, terrestrial biogeochemical cycles, and vegetation dynamics within a single, physically consistent framework. Furthermore, IBIS was one of a new generation of global biosphere models, termed Dynamic Global Vegetation Models (or DGVMs), that consider transient changes in vegetation composition and structure in response to environmental change. Previous global ecosystem models have typically focused on the equilibrium state of vegetation and could not allow vegetation patterns to change over time. Version 2.5 of IBIS includes several major improvements and additions [Kucharik et al. 2000]. SAGE continues to test the performance of the model, assembling a wide range of continental- and global-scale data, including measurements of river discharge, net primary production, vegetation structure, root biomass, soil carbon, litter carbon, and soil CO2 flux. Using these field data and model results for the contemporary biosphere (1965-1994), their evaluation shows that simulated patterns of runoff, NPP, biomass, leaf area index, soil carbon, and total soil CO2 flux agreed reasonably well with measurements that have been compiled from numerous ecosystems. These results also compare favorably to other global model results [Kucharik et al. 2000].

Description
AM Biotechnologies (AM) will develop a diagnostic system in response to SBIR Topic X10.01 Reusable Diagnostic Lab Technology that will simultaneously detect and quantify numerous protein biomarkers with excellent sensitivity. AM will enhance the current clinical gold standard immunoassay methodology by using its proprietary bead-based aptamer selection process to select dithiophosphate backbone-modified (PS2) "thio" aptamers (PS2-thioaptamers) as replacements for antibodies in immunoassays. The PS2-thioaptamers are binding agents with functionality comparable to antibodies but with very long shelf-life under ambient environment storage. The PS2-thioaptamers bind much more tightly to their targets than regular aptamers without sacrificing specificity, and are much more nuclease resistant. AM's bead-based process allows fast selection and identification of PS2-thioaptamers, which cannot be directly selected using older aptamer technologies such as Systematic Evolution of Ligands by Exponential Enrichment (SELEX). AM will demonstrate PS2-thioaptamer integration into a state-of-the-art microfluidics instrument from Sandia National Laboratory that meets NASA's form factor needs for space flight. The Phase I Project will demonstrate detection and quantification of osteocalcin (OC) using a PS2-thioaptamer in a prototype microfluidics device (TRL-4). Phase II will entail completing the panel of biomarkers for bone demineralization and delivering a prototype of the system to NASA. In Phase III, AM and Sandia will deliver a flight test system to NASA and begin FDA validation of the system for potential use in clinical diagnostics of osteoporosis as well as other conditions.

A Simulation Testbed for Dynamic Air Corridors within the Next Generation Air Transportation System Project
Published By National Aeronautics and Space Administration
Issued about 9 years ago
Summary
Description
The key innovation in this effort is the development of a simulation testbed for identifying dynamic air corridors that can increase aircraft throughput in and around the terminal airspace. In this proposal, an air corridor is a three-dimensional region of space that is intended to safely isolate a stream of aircraft from other aircraft outside the corridor. Air corridors/routes effectively exist today in two forms: static and dynamic. Static air corridors exist in the form of published standard arrival routes (STAR) and standard instrument departures (SID). Dynamic air corridors are effectively created when air traffic control (ATC) issues vector and speed instructions to aircraft. The proposed testbed would identify dynamic air corridors that provide ATC with more options that are optimized to provide greater throughput than is currently available with today's static air corridors. The testbed would continuously identify dynamic air corridors in order to adapt to changing hazards, changing queues of arriving and departing aircraft, and changing runway configurations. We further propose integrating the simulation testbed with NASA's Airspace Concept Evaluation Software (ACES) in order to assess the impact of dynamic air corridors on the entire U.S. national airspace.

Description
To enable future robotic exploration systems to have greater mobility, sensing, sampling, and communication capabilities on difficult terrain such as craters, cliffs, gullies, and skylights, Tethers Unlimited proposes to develop a "Sensing and Positioning on Inclines and Deep Environments with Retrieval" (SPIDER) system. This system employs an innovative lightweight 'orbital winch' with the capacity for rapid tether deployment and high load retrieval or towing. The unique design of the orbital winch accomplishes cable winding and deployment without rotating the spool, minimizing mass and power consumption, while eliminating the need for electrical and optical slip-ring. The SPIDER system also integrates a launcher that can be used to deploy a wide variety of tethered end-effectors to provide new capabilities for sample retrieval and sensing. A carousel of these stowed end-effectors will allow selection of appropriate implements for a desired task. For example, tethered anchor end-effectors could give planetary rovers the ability to rappel down ravines, tow themselves up steep slopes, or free themselves from a stuck position. Sensing and sampling end-effectors with data- and power- transmitting tethers can be deployed and retrieved from otherwise inaccessible areas, giving in-situ feedback via optical fibers. The SPIDER system can also be a launch platform for subsurface boring or ice-penetrating probes such as the Cryobot. Moreover, by launching an RF transmitter/receiver, the system could improve communications for a planetary rover entering a geologic feature that would impede radio contact, such as a lava tube. The Phase I effort will mature the SPIDER to TRL 4 by testing prototypes of key components, and the Phase II will mature an integrated system to TRL 6 by testing and qualifying a prototype in a relevant terrestrial environment.

Description
Binary point-cloud data for part of Barnegat Bay, New Jersey, post-Hurricane Sandy (October 2012 hurricane), were produced from remotely sensed, geographically referenced elevation measurements by the U.S. Geological Survey. Elevation measurements were collected over the area using the second-generation Experimental Advanced Airborne Research Lidar, a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the Earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The plane travels over the target area at approximately 55 meters per second at an elevation of approximately 300 meters, resulting in a laser swath of approximately 240 meters with an average point spacing of 0.5-1.6 meters. The nominal vertical elevation accuracy expressed as the root mean square error (RMSE) is 25 centimeters. A peak sampling rate of 15-30 kilohertz results in an extremely dense spatial elevation dataset. More than 100 kilometers of coastline can be surveyed easily within a 3- to 4-hour mission. When resultant elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.
Temperature profile data collected using XBTs from the HARUNA MARU from the Pacific Ocean during the Thermal Structure Monitoring Program in the Pacific (TRANSPAC) project, 11 February 1977 to 18 February 1977 (NODC Accession 8100368)

Description
Temperature profile data were collected using bathythermograph (BT/XBT) casts from HARUNA MARU in the Pacific Ocean from February 11, 1977 to February 18, 1977. Data were submitted by Scripps Institution of Oceanography as part of the Thermal Structure Monitoring Program in the Pacific (TRANSPAC) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full BT descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points (''inflection points'') required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m.

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
