Detecting Leakage from Carbon Capture and Storage Facilities Using Hyperspectral Remote Sensing Techniques

The study aims to detect the effects of leakage from carbon capture and storage (CCS) facilities using the spectral reflectance properties of vegetation. Carbon dioxide concentrations up to 80% in soil were applied to experimental plots as part of a study of the potential effects of CCS. Plant stress effects are detected by spectral scanning between 350 and 2500nm with an ASD Fieldspec FR spectroradiometer (ASD, Boulder, USA) fitted with a fibre optic probe having a 23 degrees field of view. The sampling interval over the 350-1050 nm range is 1.4 nm with a resolution of 3 nm. Over the 1050-2500 nm range the sampling interval is about 2 nm and the spectral resolution is between 10 and 12 nm. The results are then interpolated by the ASD software to produce readings at every 1 nm. Derivative analysis was used to locate the position and height of the inflection point of the red edge and other peaks that may indicate stress in plants. The study investigates the ability of hyperspectral remote sensing techniques to determine the severity of stress in crops.
