Remote sensing of vegetation stress has been posed as a possible large area monitoring tool for surface CO2 leakage from geologic carbon sequestration (GCS) sites since vegetation is adversely affected by elevated CO2 levels in soil. However, the extent to which remote sensing could be used for CO2 leak detection depends on the spectral separability of the(More)
PROBLEM ADDRESSED Leafy spurge (Euphorbia esula) is an aggressive invasive species that has invaded large areas of the Northern Plains of the United States. Mapping leafy spurge has been identified as a critical stage for management [4], and numerous attempts have been made to do so using hyperspectral imagery (e.g., [2], [5], [6]). The most successful(More)
