Summary
Description
This digital elevation model (DEM) is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Sea Level Rise and Coastal Flooding Impacts Viewer (www.coast.noaa.gov/slr/viewer). The DEMs created for this project were developed using the NOAA National Weather Service's Weather Forecast Office (WFO) boundaries. Because the WFO boundaries can cover large areas, the WFO DEM was divided into smaller DEMs to ensure more manageable file sizes. The Mobile/Tallahassee (AL/FL) WFO DEM was split into three smaller DEMS. They are divided as follows: 1. Mobile/Tallahassee (AL/FL) WFO - Mobile County in Alabama and Escambia, Santa Rosa, and Okaloosa (portion) Counties in Florida 2. Mobile/Tallahassee (AL/FL) WFO - Okaloosa (portion), Walton, Bay, Gulf, Franklin (portion), and Wakulla (portion) Counties 3. Mobile/Tallahassee (AL/FL) WFO - Wakulla (portion), Franklin (portion), Jefferson, Taylor, Dixie, and Levy Counties. This metadata record describes the DEM for the Mobile/Tallahassee (AL/FL) WFO - Wakulla (portion), Franklin (portion), Jefferson, Taylor, Dixie, and Levy Counties. The DEM includes the best available lidar data known to exist at the time of DEM creation for the coastal areas of Wakulla (portion), Franklin (portion), Jefferson, Taylor, Dixie, and Levy counties, that met project specification. This DEM is derived from LiDAR collected for the Florida Department of Emergency Management (FDEM). Hydrographic breaklines used in the creation of the DEM were obtained from FDEM and Southwest Florida Water Management District (SWFWMD). This DEM is hydro flattened such that water elevations are less than or equal to 0 meters. This DEM is referenced vertically to the North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 5 meters.

Why are rugged, low temperature actuator materials important? By themselves, they are useless; however, when fabricated into thin films and integrated into optical devices that require movement of optical surfaces for functionality, they extend the device operational envelope into temperature and environmental extremes not previously accessible. The actuator media also serves as a compliant adhesive that holds optical surfaces to rigid mechanical supports and allows optical devices to survive extremely low temperatures and harsh vibration environments such as vehicle launch without producing deleterious high voltage. Our actuator technology enables tunable optical devices without a media like liquid crystals in the optical path. Consequently, our optical devices will have superior optical performance limited only by the quality of the optical coatings and substrate surfaces. Several areas will be advanced by this new low-temperature actuator technology. High-resolution tunable optical filters such as Fabry-Perot optical filters are needed in direct-detection LIDAR applications to spectrally resolve the back scattered radiation broadened by temperature and Doppler-shifted by atmospheric winds. When used in imaging spectrometers, the ability to cool the narrowband optical filter and retain etalon plate motion will allow greater instrumental sensitivity to resolving trace ChemBio species. Our rugged low temperature actuator technology could enhance device operation on airborne and satellite platforms.

This Phase 2 SBIR proposal describes the design, fabrication and calibration of a brass-board Self-Calibrating Vector Helium Magnetometer (SVHM). The SVHM instrument is capable of making high accuracy vector component measurements of Earth and planetary magnetic fields. The major SVHM innovation is use of scalar field measurements made with the SVHM sensor to self-calibrate the vector measurements thereby eliminating the standard suite of three fluxgate vector magnetometers and the independent scalar magnetometer required to correct for fluxgate drifts and offsets. The SVHM bread-board conceptual design can achieve a dynamic range of !S65,000 nT, both vector and scalar accuracy with self-calibration of !S1 nT, and sensitivity of <10 pT /?)Hz. The SVHM bread-board will be miniaturized to meet volume, power and mass goals. The SVHM bread-board will utilize a fiber-coupled laser pump source and resonance drive, which permits reduction of helium cell volume by a factor of 10 and eliminates resonance drive coils and cables. The feasibility of designing a brass-board SVHM model using advanced laser and digital components was established in Phase 1. The SVHM bread-board will be calibrated and the self-calibration function demonstrated at a NASA coil facility during Phase 2.

Wintering snow goose populations have increased dramatically in the vicinity of Bombay Hook National Wildlife Refuge during the last 20 years. Peak populations have risen from 1,500 in 1968 to over 198,000 in 1997. The birds concentrate their feeding activities in a relatively small portion of the refuge salt marshes and create eatouts, areas of marsh stripped of vegetation, following their feeding activities. Beginning with the 198384 season the refuge opened portions of the marshes to public snow goose hunting. Since it was noted that most damage occurred shortly after the birds arrived in October, a special early hunt was permitted prior to the regular State waterfowl season beginning in 198788 which has continued since that time. With the advent of snow goose hunting in Bombay Hooks marshes changes in the birds use patterns on Bombay Hook and surrounding areas were noted. Concentrations of the birds began using Prime Hook National Wildlife Refuge, the Little Creek Wildlife Management Area, as well as private lands to the west into Marylands eastern shore. This study was proposed to documentand monitor the habitat preferences, population fluctuations, and vegetation changes associated with the snow goose flocks in the Bombay Hook Area.

<p>Life support systems on human&nbsp;spacecraft are designed to provide a safe, habitable environment for the astronauts, and one of the most significant challenges is managing acceptable air quality. Carbon dioxide (CO<sub>2</sub>) is an important trace gas produced by human metabolism that must be actively removed from spacecraft cabin atmosphere.</p><p>The Carbon Dioxide Removal Assembly (CDRA) currently on board the ISS performs the carbon dioxide (CO<sub>2</sub>) removal function as part of the on-board Atmosphere Revitalization System (ARS). It is considered the state-of-the-art for manned spacecraft cabins, but has two significant drawbacks:</p><p>1. The CDRA requires that air be dried prior to CO<sub>2</sub> capture, and this costs energy &ndash; in fact, the system uses much energy drying the air than is&nbsp;required for&nbsp;capturing and releasing carbon dioxide.</p><p>2. The CDRA works in batch mode, requiring complicated valving and control to switch between sorbing and desorbing beds, while downstream CO<sub>2</sub> processing systems can operate on a continuous stream of CO<sub>2</sub>. This adds unnecessary complexity, as well as a second parasitic energy loss.</p><p>An ideal system would process CO<sub>2</sub> continuously without any need for drying of the air, and without any moving parts. Such a system would require a fraction of the size and weight of the CDRA while dropping the cost of CO<sub>2</sub> capture by 5X or more. Such a technology would be enabling for future long term manned flight missions, such as a mission to Mars. This element is developing a new electrochemical membrane technology using patented innovations in electrolyte materials. Technology development began under a Phase I effort funded by the NASA Advanced Innovative Concepts Program.</p><p>The prior Phase I effort&nbsp;demonstrated the functionality of the basic approach to CO<sub>2</sub> separation, demonstrating CO<sub>2</sub>&nbsp;removal using&nbsp;only electrical input using&nbsp;a film in a membrane configuration. Membrane synthesis and fabrication techniques were developed that allowed for the successful incorporation and retention of an electrochemically active carrier molecule&nbsp;using composite liquid membrane technology. This allowed for the successful demonstration of a continuous CO<sub>2</sub> capture rate at 40% in a single step with no moving parts. A higher capture rate of 80% was demonstrated in a batch mode during this phase.&nbsp;&nbsp;The work gave promise that highly efficient, low energy separation of CO<sub>2</sub>&nbsp;was possible using this technology, with&nbsp;the potential&nbsp;of operational energy savings as high as 80%&nbsp;compared with the state of the art, together with a weight and size footprint that could be as much as 75% smaller. The key enabling technology &ndash; composite liquid membrane materials &ndash; allow creation of a functional electrochemical membrane in a thin film form factor that enables this technology and application.&nbsp; This prior work, however, demonstrated CO<sub>2</sub> from nitrogen gas only, not humidified air.&nbsp; It will be a technical challenge to&nbsp;prove the concept&nbsp;in representative cabin atmosphere containing moisture and oxygen.</p><p>This Element, representing Phase II tasks, will focus on modifying the composite membrane system, evaluating active carrier molecules, ionic liquid solvents and membrane properties to operate the system efficiently in humid air.&nbsp;&nbsp;Reliability and performance&nbsp;of&nbsp;the system&nbsp;will be evaluated.&nbsp; Finally, a&nbsp;subscale system&nbsp;for a prototype air purifier will be designed. The effort will include&nbsp;increasing the size of the test cell and demonstrating long-term operation of the membranes under simulated cabin air (oxygen and nitrogen mixture with moisture), consistent with NASA requirements.</p>

Black Forest Engineering has identified innovative modifications in uncooled focal plane array (UFPA) architecture and processing that allows development of large format long wavelength infrared (8-14 ?m) imaging sensors to meet future NASA system requirements for a light weight, low power, and radiation tolerant imager. These modifications allow development of bolometer-based large format UFPA, with a pixel pitch of 20-?m and 1024x768 pixel elements with sensitivity comparable to commercially available UFPAs with 30-?m pixel pitch. The identified modifications are applicable to amorphous silicon bolometer-based UFPAs, such as those manufactured by Raytheon Commercial Infrared in Dallas, Texas.

The Historical Land Cover and Land Use data set was developed to provide the global change community with historical land use estimates. The data set describes historical land use changes over a 300-year historical period (1700-1990).Testing against historical data is an important step for validating integrated models of global environmental change. Owing to long time lags in the climate and biogeochemical systems, these models should aim to simulate the land use dynamics for long periods, i.e., spanning decades to centuries. Developing such models requires an understanding of past and current trends and is therefore strongly data dependent. For this purpose, a historical database of the global environment has been developed: HYDE. Historical statistical inventories on agricultural land (census data, tax records, land surveys, etc) and different spatial analysis techniques were used to create a geographically-explicit data set of land use change, with a regular time interval. The data set can be used to test integrated models of global change. Continental-scale historical data were used for that period.

FUNCTION: Studies coastal ocean processes with autonomous underwater vehicles (AUVs). Maintains, tests, ballasts, and prepares for deployment the Slocum Electric Glider AUV built by Webb Research Corporation. Slocums are designed to independently perform wide-area ocean surveys of temperature and salinity for up to about one month. DESCRIPTION: Slocum gliders are equipped with temperature/salinity/pressure sensors and with real-time satellite connection to the Iridium newtork. These gliders, unlike conventional AUVs, have no active propulsion system and instead rely on a battery-induced change of buoyancy and active control surfaces to glide through the coastal ocean from the surface to the bottom and from the bottom to the surface in a saw-tooth pattern. This system requires low amounts of power and therefore the gliders do not need to carry heavy battery payloads and can be deployed over long-duration missions (&gt;30 days). An altimeter is used to prevent bottom collisions. Two-way communication of data/instructions occurs through Iridium satellite or freewave radio when the gliders are on the ocean surface. The central payload of the gliders can be equipped with various instruments for ocean measurements. The coastal gliders can dive to 200 meters depth. INSTRUMENTATION: A Slocum glider typically carries an altimeter and a Sea-Bird CTD (temperature, salinity, and depth) as part of a fundamental sensor faculty. Vertically averaged current velocity can be calculated using the difference of the actual glider track with the programmed track and surface current velocity can be calculated using the consecutive GPS fixes while at surface. Additional sensors include Wetlabs BB3 (optical backscattering), FL3 (fluorescence), and AUVB (total volume scattering).
