Project Skills: Remote Sensing - Studying crops using hyperspectral satellite imagery and developing methods of analyzing hyperspectral data in the cloud computing environment Google Earth Engine
Other Interests/Skills: Invasive plant species, plant communities, diversity.
Current/Recent Projects: Currently I am studying eight globally major crops (alfalfa, barley, corn, cotton, rice, soybean, and wheat) using Hyperion imagery in Google Earth Engine to classify these crops and estimate their biochemical and biophysical characteristics to address global food security. Additionally, I am constructing a hyperspectral library of these crops in various phenological stages, environmental conditions, and management regimes. I am also exploring best methods of data reduction and best bands and indices to estimate crop biophysical and biochemical characteristics using hyperspectral data.

Geographic Regions: Southwest and Western United States, Northern Mexico, Ambos Nogales, Patagonia Mountains, Naco/Naco, Bisbee, Douglas, Agua Prieta, Lower Colorado River, Mexican Highland Ecoregion, and the Madrean Sky Island Archipelago.
Current/Recent Projects:
  1. Working with partners, water harvesting structures are being installed and monitored for progressand success rates over time. Terrestrial monitoring documents the hydrological impacts of waterharvesting devices and helps identify sits for future installation. Landsat Thematic Mappersatellite imagery and the derived Normalized Difference Vegetation Index (NDVI) values are beingused to monitor changes in vegetation greenness at a desert wetland. Hydrological geospatial models,including the Soil and Water Assessment Tool (SWAT) and the Kinematic Runoff and Erosion Model(KINEROS2) are being used (with Terrestrial LiDAR (T-LiDAR) datasets) to monitor changes in surfaceflow, infiltration, and sediment build-up at new check dams and detention features. T-LiDAR data arealso being used to examine changes in vegetation structure and channel dimensions. Hydrographs aredeveloped using Continuous Slope Area methods to be input to calibrate watershed models forlong-term predictions. Visit the Aridland Water Harvesting Study Website

  2. In cooperation with the US EPA, Southwest Ecosystem Services Project, the USGS developed the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM). The SCWEPM tool will help to formalize andbroaden the scope of the decision-making process by representing ecosystems services equally viaeconomic valuation to be considered more readily in scenario and trade-off analyses in thiscrossborder watershed.

  3. In the Ambos Nogales binational watershed, developing appropriate land-use, watershed-management, and flood-attenuation plans are critical. Results were derived from coupling urban growth, hydrological, and nonpoint source pollution models to make estimates of current, future, and hypothetical conditions. Geographic Information Systems (GIS), remote sensing, and a watershed approach were used to create products used in a comprehensive plan for sustainable development at Ambos Nogales.

  4. The USGS U.S.-Mexico Border Environmental Health Initiative (BEHI) project is responsible for the development and hosting of transboundary datasets, standards, and web mapping services working in close collaboration with the Mexican Geography and Census Bureau (INEGI) and the International Boundary and Water Commission (IBWC). A multidisciplinary team of scientists under the BEHI, developed a research and monitoring program to understand and document the complex movement of natural and anthropogenic contaminants through the Upper Santa Cruz River Watershed.

Other Interests/Skills: Geostatistics.
Geographic Regions: Southwestern US, Arizona, California.
Current/Recent Projects: Southern California Multi-hazards demonstration project (MHDP):
As a part of the wildfire and debris flow hazards assessment for the Southern California MHDP, this research will characterize the impact of past management activities on loss of native plant communities and replacement by functionally different non-native assemblages. In collaboration with Jon Keeley (USGS-WERC, adjunct at UCLA), I am using satellite data to regionally map occurrences of alien-invasive grasses and forbs in the chaparral communities of Southern California. Based on the distinctive phenology of the alien-invasives, I am selecting a suite of Landsat images to model their current regional distribution. Using historical Landsat data I will extrapolate these results both temporally and spatially to compile a record of vegetation-conversion change across the southern California region back to the 1970’s.

Phenology and Land Cover Change:
Phenology, the study of the timing of biological events, is increasingly regarded as a key to understanding many phenomena that are related to land cover and land use change, global scale climatic change, and human health. Remote sensing of phenology provides a mechanism to move from plant-specific to regional and continental scale studies of phenology. Changing land use has an important impact on surface characteristics that subsequently affect land/atmosphere interactions (e.g., albedo, water, carbon). This project will develop methodologies for summarizing phenological impacts of land cover change by coupling satellite phenology with detailed land cover change information.

Regionally-mapped environmental variables for the Mojave Desert:
Total cover of perennial and annual vegetation are important measures of a number of processes in the Mojave Desert, including soil-moisture availability, stability of biological soil crusts, and the ability of disturbed areas to recover. Perennial vegetation was derived using Moderate Resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI) data coupled with pre-existing field transect data and applying step-wise linear regression techniques. Potential annual vegetation was derived using data mining and exploration techniques to reveal appropriate multi-image calculations applied to MODIS-EVI data that correlate with field data collected 2003 and 2005 at 50 plots. These maps are being used in the Mojave Desert tortoise habitat models and in Mojave Desert dust emissions studies.

Project Skills: Hazards - Community vulnerability assessments to tsunamis, volcanic lahars, hurricane storm surge, coastal storms, and sea level rise
Climate Change - Assessing future community vulnerability to climate-change-enhanced natural hazards (e.g., storm surge, erosion)
Land Use/Land Cover Studies - Use of landcover data for approximating community vulnerabilityto natural hazards
Tools and Techniques - Statistical approaches for summarizing data
GIS - Spatial analysis for vulnerability research
Geographic Regions: Oregon, Washington, Hawaii, Florida.
Current/Recent Projects: Detailed project information can be found at  [http://geography.wr.usgs.gov/science/vulnerability/index.htm].

1) Community vulnerability to tsunamis: Past research has included USGS reports summarizing variations in community exposure to tsunamis in Hawaii, Oregon, and Washington and journal articles describing various geospatial techniques to assess societal vulnerability to tsunamis. Wood was also a committee member for a National Research Council review of the nation's tsunami warning system and national preparedness for tsunamis. Current research focuses on developing geospatial approaches to characterize pedestrian evacuations from tsunamis and to develop societal-risk metrics for tsunamis.

2) Community vulnerability to climate change and coastal storms: Research focuses on assessing current and future community vulnerability to coastal storms, sea level rise due to climate change, and increasing urbanization of hazard-prone areas. Past research has focused on Sarasota County (Florida) and Kauai Island (Hawaii). Current research focuses on community vulnerability on the Oregon and Washington coast to climate-change-enhanced coastal erosion in collaboration with Oregon State University, via a grant from the NOAA Climate Change Program.

3) Community vulnerability to volcano hazards: Research focuses on assessing community vulnerability to volcanic hazards, such as lahars, in the Cascade Range. Research efforts also include development of societal-exposure metrics for national volcano monitoring and preparation of a textbook on volcano-hydrologic processes with USGS colleagues in the Volcano Hazards Program
