  3. I. Introduction Climate change Global warming

  4. What is Carbon Capture and Storage (CCS)/ Geologic Carbon Sequestration (GCS)? - Solution of CO2 reduction emission Source: The Intergovernmental Panel on Climate Change (2005)

  5. World-Wide projects Active CO2 storage demonstration projects around the world (CO2CRC, 2010)

  6. Proposed CO2 storage demonstration projects around the world (CO2CRC, 2010)

  7. Why monitoring GCS? 1. To ensure and verify of geologic carbon sequestration site 2. Safety and environmental concerns 3. To resolve any disputes arising from conflicts of use of the subsurface and possible contamination of underground resources

  8. Flux measurement Monitoring Techniques Isotope measurement Ground penetrating radar Source: Monitoring techniques (Benson, 2008) Soil gas sampling Seismic

  9. II. Mammoth Mountain Location: Inyo National Forest, CA, USA Coordinates: 37°37′50.26″N , 119°1′57.45″W Elevation: 11,059 ft (3,371 m)

  10. Natural CO2 and Environmental impact Invisible CO2 Gas Killing Trees at Mammoth Mountain, California (USGS, 2004 ) • In 1989, there was a swarm of small earthquake in the central region of the Sierra Nevada, CA and a dormant volcano is woke up after 760,000 years of sleeping • The swarm center was located beneath the mammoth mountain 2 km below the surface

  11. - In early 1990’s, there was the first notice of dead and dying trees on the south side of Mammoth Mountain Source: USGS(2004) - In1994, USGS surveyed for carbon dioxide gas around Mammoth mountain , and exceptionally high concentrations of gas were found in the soil beneath the trees Source: USGS(2004)

  12. CO2 leakage models: Natural VS GCS Natural leakage model (USGS, 2004) CO2 storage leakage model ( Damen et al., 2005)

  13. Using multispectal imagery Large area coverage Availability of data set: before and after event Objective To verify the usefulness of high altitude, low resolution Landsat TM image for monitoring natural CO2 leakages in order to apply in real sequestration site

  14. III. Methodology Data set: using Landsat 5 TM acquired on September of year 1988, 1992, 1993, 1994, 1995, 1996, 1999, 2003, 2004, 2005, 2008, 2010 Normalized Difference Vegetation Index (NDVI) is vegetation index which is calculated from the visible and near-infrared light reflected by vegetation. A Landsat TM scene, NDVI is given by the following formula: NDVI = (NIR — VIS)/ (NIR + VIS) Where; NIR = near-infrared light (band 4) VIS = visible light (band 3)

  16. IV. Result

  17. Spectrometer field results (USGS, 2000) According to USGS (2000), the spectrometer field results show that carbon-isotopic analyses of the annual growth rings in trees near the margins of the tree-kill areas imply that the gas-emission rate reached a peak in 1991, subsequently declined, and then have been relatively stable since about 1996

  18. The SVM classification result shows the area of dead/dying tree was in similar location to the USGS result. However, the comparison of total coverage of classification result may not always provide the most efficient analysis of changes due to the difference in vegetation spectral

  19. V. Conclusion - NDVI change detection of high altitude, low resolution Landsat TM can provide the useful vegetation health information related to both areas of dead/dying trees and vegetation in not affected by CO2 leakage - Particularly, we confirmed that the area of detected dead/drying vegetation at Mammoth Mountain agrees with the field survey result by USGS - The continual monitoring using satellite data set for natural leaking analogue will benefit the monitoring of the actual CO2 sequestration site in a long term time scale

  20. Further research - Future research also might aim to use high resolution multispectral satellite image and hyperspectral satellite image to provide large area coverage into the actual CO2 sequestration site - The combination of both imagery, optical and radar remote sensing should be concern for long term monitoring in order to ensure the safeguard of CO2 storage sequestration site
