Assessing the Impact of Ordinances, Outreach and Enforcement on the Resiliency of Gulf Coastal Watersheds
This study explores the link, if any exists, between ordinances and regulations and NGO's (non-governmental organization) compared to water quality. GIS is used to map the codes and regulations, NGO's and water quality spatially. This allows for data analysis that can reveal relationships between watershed regulation and water quality. The spatial data gathered in Year 1 will inform the development of focus group topics and questionnaires as the study continues.

Coastal Ocean Color Trade Study
GRI scientists have created a system of unique data sets to enable a better understanding of environmental processes that occur in coastal environments. Coastal and inland waters and their environments were targeted for the initial mission due to their importance to various aspects of human activity and the inability of current systems to accurately sense these unique environments. This mission works in support of the planned GEO-CAPE satellite mission that monitors these environments and is critical for evaluating and understanding the spatial variations and dynamics associated with coastal environments.

Coastal Resiliency from Hurricane Impacts
Coastal wetlands provide a line of defense for coastal communities against hurricane impacts. The wetlands can reduce wind, wave, and surge energy which will in-turn reduce the damaging effects of hurricanes on coastal infrastructure and communities. Research has been developed to improve our understanding of coastal resiliency from hurricane impacts in regards to wetland areas. This was achieved by using integrated numerical modeling and in-situ observations and remote sensing techniques.

Developing a Foundation for Analysis of Natural and Human-Induced Disturbances to Coastal Economies
This project focuses on the relationship between people and the ecosystems, resources, and hazards of the Gulf Coast. Because almost all human decisions are dependent on time, uncertainty (risk), cost, and expected benefits, this project can shed light on how the choices of coastal residents, businesses, and other entities are influenced by those characteristics unique to the coast. Furthermore, because economic analysis is always geared toward understanding the value of things and how these values influence decisions, this project will provide a wide range of cost and benefit estimates that can be utilized by decision-makers at all levels to make choices that improve the quality of life along the Northern Gulf Coast.

FloodViz: Visual Analytics for Assessment and Interpretation of Simulated River Flooding
The FloodViz project involves the development and testing of visual analytics software to enable scientists and forecasters to better interpret and distribute hydrologic information. This software will be useful in the research community as an interpretation tool for river level and flood data. The tools developed serve as a useful platform for hydrologic forecasters within the National Weather Service to more quickly and accurately determine areas at risk for flooding and allow NOAA river forecasters to better visualize the extent of flooding. Additionally, these tools allow forecasters to relay more information to the emergency management community while issuing forecasts to help protect lives, property and the nation.

Forecasting Episodic Changes in Hurricane Intensity and Structure over the Gulf of Mexico
The primary goal of this proposed initial one-year project is to provide greater insight into forecasting time-sensitive trends of rapid formation, changing intensity, and changing wind field area (or size) of hurricanes over the Gulf Mexico in the interest of reducing the uncertainty in the risk posed to Gulf Coast residents and infrastructure. The focus would be to identify key features or processes present in the ambient atmosphere and in the Gulf of Mexico that led to critical episodic changes in the intensity and structure of recent hurricanes: Humberto, Gustav, and Ike.

GeoVol-Geospatial Volume Rendering
This project created software using direct volume rendering techniques that achieved real-time performance and high image quality. A user study was conducted to compare the implemented volume rendering technique with state-of-the-art isosurface rendering to examine hurricane data. The results of the study established that both volume rendering and isosurface visualizations were effective in examining data from computer simulations of hurricanes. Because of the higher image quality and the interactive frame rates, direct volume rendering was preferred. Future studies will be conducted to quantify performance differences between using the traditional 2D methods and the 4D methods.

Health and Productivity of Louisiana Salt Marshes
This study will allow the identification of hotspots of marsh degradation in Louisiana by evaluating marsh biophysical characteristics including distribution of chlorophyll content, green leaf area and green marsh canopy cover. This assessment of marsh health and productivity is due to the Deepwater Horizon oil spill. NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images will be used to retrieve and map these characteristics across the coastal Louisiana salt marshes before and after the spill. The maps and tools produced from the study will be helpful to coastal managers across Louisiana as they evaluate and prioritize the marsh restoration effort which will take place due to the oil spill. Tangible map products will be generated for the first time that can quantitatively assess the effect of the restoration activities and speed of marsh ecosystem recovery.

Hurricane Landfall Estimation and Storm Surge
The storm surge of Hurricane Katrina, which made landfall in Mississippi and Louisiana in 2005, was unprecedented for its elevation, area coverage, and levee breaches. Due to the storm surge, areas along the Gulf Coast were severely flooded and destroyed. GRI is addressing recent Mississippi and Louisiana storm surge issues using the finite element model ADCIRC. The research will facilitate answers to the sensitivity of the storm surge in Mississippi to wind profiles of major hurricanes, as well as to hurricane eye size and landfall estimation.

Toward an Understanding of Gulf Coast Resident Preferences on Risk and Restoration
The results of this work will provide useful insights into whether seemingly anomalous coastal risk taking behavior can be explained by more robust behavioral models. Policy makers and scientists concerned with coastal management will obtain clarification of whether coastal resident behavior is driven by a lack of information, misguided perceptions, or simply personal preferences. Additionally, this work will allow for identification of perceived benefits from restoration and how individuals prioritize them. Finally, it may allow for identification of incentives that can be used to induce socially-optimal behavior.
